Using Xprint an application can + search, query and use devices like printers, FAX machines or create + documents in formats like PDF or SVGprint. In particular, an + application can seek a printer, query supported attributes (like paper + size, trays, fonts etc.), configure the printer device to match it's + needs and print on it like on any other X device reusing parts of the + code which is used for the video card Xserver... + Q: + + Where can I get Xprint/Xprt from ? + A: + + Xprint is client-server based, therefore two answers: + * The server side is available by default on Solaris (see [143]Note + below) and HP-UX (Xfree86 ships a "Xprt" binary, but that is + broken and the server config files are missing, too). For those + platforms who do not have a (working) Xprt server the you can get + source, binary tarballs and Linux RPMs from + [144]http://xprint.mozdev.org/, Debian Linux has a package based + on the same sources (see + [145]http://packages.qa.debian.org/x/xprint-xprintorg.html). + +Note + For Solaris >= 2.7 [146]http://xprint.mozdev.org/ provides the + "GISWxprintglue" and "GISWxprint" packages (available from + [147]http://xprint.mozdev.org/download.html) which provides a + single-step drop-in way to configure and start Xprint at system + startup and/or per-user for all applications and users (the + package provides only startup scripts and some config data and + uses the Xprt binary provided with Solaris + (/usr/openwin/bin/Xprt)). + * The client-side Xprint support library (libXp.so) is available on + all X11 platforms >=R6.4, including Linux, Solaris, HP-UX, AIX, + FreeBSD, NetBSD, etc. + If you do not have it you can build it from the sources available + at [148]http://xprint.mozdev.org/. + + Q: + + What is "Xprt" ? + A: + + Xprt is the server-side of Xprint. It's just like any other Xserver - + it uses only an other kind of output device (printer instead of + framebuffer) and implements an extra X11 extension ("XpExtension") to + handle the special features/requirements of a "paged device"(=printer + etc.). + Q: + + Where can I get help for problems with Xprint ? + A: + + The current main site for the Xprint development is + [149]http://xprint.mozdev.org/ which hosts various resources including + a [150]mailinglist (please subscribe before posting) for end-users, + admin and developers. + Q: + + "Why do some people like Xprint ?" / "What are the advantages of + Xprint ?" + A: + + * Xprint allows an application to query what features (paper size, + trays, orientation, resolutions, plexes, fonts and much more) a + printer supports. For example it is avoidable that a user + accidently prints DIN-A4 on a DIN-A0 poster printer (the print + dialog would only offer DIN-A0 as paper size, e.g. offers only + choices which are valid for this printer). + * Server-side, localizeable configuration - changes to the server + config apply to all users without the need to change/updating + anything on the user side (the user may still start his/her own + Xprt instance using his/her preferred configuration). + * Small footprint - ideal for for mobile devices (client side does + not need to process any fonts - that's the job of the server + side). + * API not restriced to PostScript (X11R6.5.1 comes with PCL and + Raster implementations - and PDF/G3-FAX/SVG would be possible + without problems). + * Scaleable - Xprint can use as many Xprt servers as the user/admin + wants. + * "Xprint is designed for the enterprise", e.g. Xprint was designed + to match the needs of large company networks. + * Automatic font handling - font download or the existence of + printer-builtin fonts is automagically handled by Xprt - the + application does not need to know/handle any details (but the + application can optionally get information and control the usage + of printer builtin fonts). + * You can print anything what you can render on the + framebuffer(=video card) Xserver. + * Existing code can be reused 1:1 for printing - which means reduced + development costs. + * Easy support for I18N (internationalization) - you simply render + any fonts in any language with Xprint. + * Network-transparent design - Client can use local or remote Xprt + servers like any other Xserver. + * Uses the X11 protocol - easy adoption of existing code to + implement printer support. And all the network goodies like + firewall proxies, compressors etc. can be used for Xprint without + modifications. + * Security: Xprint can use all authentification schemes available in + X11 (like Kerberos5, SecureRPC, MIT-MAGIC-COOKIE or host-based + authentification). + * Enhachements on the server side (Xprt) to not require the change + of client-side code. + * Optimized job output (like the PostScript created by the + PostScript DDX) is usually a lot smaller than the PS code created + by other PostScript engines. + + Q: + + Why do some people dislike Xprint ? + A: + + There are a few common misconceptions about Xprint. Let's take a look + some of these "myths", some background - and the facts: + + Myth: [151]Xprint prints just a XWD dump of the Xserver bitmap + Myth: [152]Xprint cannot handle non-'ISO Latin 1' chars + Myth: [153]Xprint uses a 1024x768 screen resolution to render the + stuff on the paper - therefore it will never be able to do + high-resolution stuff + + Myth: [154]Xprint prints only graphics(=bitmap/gfx) fonts + Myth: [155]Xprint does not support pages sizes larger than DIN-A4 + Myth: [156]Xprint does not support rotated text + + Myth: + + " Xprint prints just a XWD dump of the Xserver bitmap " + Fact: + + Whoever says Xprint simply does an "xwd"-like dump is wrong. + + In short, Xprint currently (X11R6.5.1) supports *four* drivers: + 1. X to native Postscript + 2. X to native PCL5 + 3. X to native PCL3 + 4. X to a raster which is then feed to something like xpr to create + PS or PCL5 wrapped rasters. + + In long, the original X Print Service ("XPS") was attempted during CDE + 1.0, and they only got so far as the "raster" driver. + + As CDE 2.0 came around, Bob Schiefler and others at the X Consortium + agreed that the X Consortium would work on a X to native PS Level 2 + driver and HP would work on a X to native PCL5 driver. + + It was probably the CDE 1.0 effect that left many people with the + impression that Xprint is all about xwd-like window dumps. NO! Xprint + has native PostScript and PCL5 printing and more drivers (like PDF and + SVGprint DDXs etc.) are in the development. + Myth: + + " Xprint cannot handle non-'ISO Latin 1' chars " + Fact: + + Xprint can print any chars incl. those required for MathML, Hebrew, + Arabic, Japanese etc. etc. For example - the Xprint module for + Mozilla5 is the only print module which can proprtly print MathML. + Myth: + + " Xprint uses a 1024x768 screen resolution to render the stuff on the + paper - therefore it will never be able to do high-resolution stuff " + Fact: + + Xprt uses the screen resolution requested by the application or the + printers default resolution. For example a 300 DPI printer which + supports paper sizes up to DIN-A4 will get a screen with 3300x3300 + pixels (screen width and height are usually equal to support per-page + changes in the orientation (potrait/landscape etc.), the window size + would be 2400x3149 for "portrait" orientation) - and larger + resolutions will result in larger screens. + Myth: + + " Xprint prints only graphics(=bitmap/gfx) fonts " + Fact: + + In short, Xprt supports printer-builtin fonts and can download fonts + to the printer if they do not exist on the printer. + + In long, this myth seems to have it's root in a feature of Xprt which + can - if Xprt gets misconfigured - disable the use of printer-builtin + fonts and the ability to download fonts. + + Xprt's PostScript and PCL DDX have the unique feature to create font + glyphs from bitmap fonts if they are not available as printer-builtin + fonts nor as PostScipt Type1 fonts. However this is the fallback - the + last option used by Xprt. Used if everything else fails. But when + someone does not pass any PS Type1 fonts with the font path nor + configures a printer model-config (which contains a description of the + features&fonts supported by the printer) Xprt will never have a chance + to use them. And if everything else fails it has no other option than + using what has been left - the bitmap fonts... + Myth: + + " Xprint does not support pages sizes larger than DIN-A4 " + Fact: + + There is no such limitation. The only limit is the 16bit coordinate + system of the X11 protocol - which is large enougth that Xprint can + support paper sizes larger than DIN-A0 oversize papers. There is no + problem with creating your own monster-size DIN-A0 posters using + Xprint-based applications. + Myth: + + " Xprint does not support rotated text " + Fact: + + Xprint and all it's drivers support the X11 matrix XLFD enhancement + introduced in X11R6 (and future versions of Xprint will support the + [157]STSF font API which supports matrix transformations as well). + Fonts can be rotated at any angle. Take a look at the [158]SOFTWARE + DEVELOPMENT section in this FAQ for examples... + + Q: + + Does Xprint support anti-aliased fonts ? + A: + + Question back: When do we need anti-aliased fonts ? Anti-aliasing is a + "hack" to work around the limitations caused by the low resolution of + monitors - they usually operate between 72 DPI and 150 DPI. + + But Xprint operates on printers where the usual minimum resolution is + 300 DPI (today's normal office printers support resolutions ranging + from 300 DPI up to 2400 DPI depending on the model; most common is 600 + DPI). Anti-aliasing at those resolutions is not required anymore. + Additionally many printers support their own font anti-aliasing at + lower resolutions which is far better and faster than it could be + "done" on the client side. + Q: + + How can I check if Xprint is working and should be used ? + A: + + Check whether the ${XPSERVERLIST} env var is set or not. If + ${XPSERVERLIST} is set then Xprint is available and should be used. + Q: + + How can I view PS(=PostScript) files ? + A: + + * On Unix/Linux (general): + + GhostScript ("gs") and GhostView ("gv" and it's KDE- and + Gnome-specific versions "kghostview" and "ggv") + + * Solaris: + + /usr/dt/bin/sdtimage (DPS-based image viewer for CDE) + + /usr/openwin/bin/pageview (DPS-based image viewer for + OpenWindows) + + Q: + + How can I view PCL files ? + A: + + XXX - [159]xprint.mozdev.org bug 2261 has been filed for that issue. + Q: + + How does Xprt find fonts ? + A: + + Lookup-rule for Xprt's PostScript DDX to find fonts: + 1. Printer-builtin fonts (defined by the fonts/-dir in the + model-config) + 2. PostScript fonts (will be downloaded via generated print job) + 3. GFX-fonts build from X11 scaleable fonts + 4. GFX-fonts build from X11 bitmap fonts + + Q: + + How can I print TrueType fonts with Xprint ? + A: + + 1. Linux Xprt build from [160]http://xprint.mozdev.org/'s source + supports TrueType fonts out-of-the-box (starting with the 008 + development tree; xprint.mozdev.org's releases <= 007 do not + support TrueType fonts) and and does not require any special + actions. + 2. Sun's Xprt on Solaris (/usr/openwin/bin/Xprt) has TrueType font + support out-of-the-box and does not require any special actions. + 3. You can setup a TTF-aware X font server ("xfs", see xfs(1x)) with + the matching TrueType fonts and add the font server location to + Xprt's font path. + 4. Sourceforge has a TrueType to PostScript Type 1 converter project, + see [161]http://ttf2pt1.sourceforge.net/download.html. You may + convert the TTF files into PT1 files that Xprt can download them + to the printer on demand... + + Q: + + What does "DDX" mean ? + A: + + "DDX" is a short term for "Device Dependent X" - the device-specific + layer of a Xserver ([162]"DIX"(="Device Independent X") is the + counterpart). + Q: + + What does "DIX" mean ? + A: + + "DIX" is a short term for "Device Independent X" - the non-device + specific code of a Xserver ([163]"DDX"(="Device Dependent X") is the + counterpart). + Q: + + What does "PDL" mean ? + A: + + "PDL" is a short term for "Page Description Language". Examples for + PDLs are PostScript, PCL, PDF and SVGprint. + Q: + + I have twenty printers installed on my system - but Xprt only shows + two screens. Where are all the other printers ? + A: + + A Xprt screen does not represent a single printer. A Xprt screen + represents a single DDX (currently supported are PostScript, PCL3/5 + color, PCL mono and "raster" output(=1bit deep bitmap). + Q: + + Which platforms support Xprint ? + A: + + All platforms which support X11 >= R6.4 can use Xprint. The client + side (libXp.so) is available on Linux/FreeBSD(=Xfree86), Solaris, + HP-UX and AIX and the Xprt server side is available by default on + Solaris and HP-UX (Xfree86 shipps with a Xprt binary - but that is + broken and unuseable). The client-side extension library (libXp.so) + can be compiled on any platform, the Xprt server needs minor + adjustments for the specific platforms... If your platform does not + have Xprint (client-side and/or server-side) you can get the sources + from [164]http://xprint.mozdev.org/. + Q: + + I have the broken Xfree86 Xprt binary on my system. Do I need a new + version of libXp.so (the client side X11 extension library for + Xprint), too ? + A: + + No, the libXp.so shared library shipped with Xfree86 or build from + Xfree86 sources is not broken, only the server side ("Xprt") is buggy. + There is no need to replace the library. + Q: + + Which spelling is correct - "Xprint", "XPrint", "Xprinter" or Xprt" ? + A: + + "Xprint" is the correct one - "XPrint" is just a typo, "Xprinter" is a + complety different product not related to X11/Xprint and "Xprt" is + only the "X11 print server"(=the server side of Xprint). + Q: + + Which applications support Xprint ? + A: + + There are various applications which support Xprint: + * Motif/LessTif (full framework incl. special widgets like + XmPrintShell) + * [165]Common Desktop Environment (CDE) 2.x + * [166]Mozilla + * Eclipse + * KDE/Qt support is comming is planned for the end of Dec/2003 + * StarOffice 5.x + * etc. + + Q: + + Is "Xprint" "mozilla"-only (I saw that it's hosted by mozdev.org) ? + A: + + No, Xprint is a general-purpose print API based on the X11 API used by + many applications ([167]mozdev.org is just hosting the development + area, but this does not mean the project is limited to mozilla... :)). + Q: + + Under which license is the source code from xprint.mozdev.org + distributed under ? + A: + + That's the plain "MIT" license, the same as used by Xfree86.org and + X.org: +Copyright (c) <year> <copyright holders> + +Permission is hereby granted, free of charge, to any person obtaining a copy of + this software +and associated documentation files (the "Software"), to deal in the Software wi +thout +restriction, including without limitation the rights to use, copy, modify, merg +e, publish, +distribute, sublicense, and/or sell copies of the Software, and to permit perso +ns to whom the +Software is furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or +substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPL +IED, INCLUDING +BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR +PURPOSE AND +NONINFRINGEMENT.

What is that for a thing ?! + + Q: [182]How can I forward Xprint services when logging-in via ssh to + another machine ? + + Q: + + How do I configure Xprint on the client side ? + A: + + There are two env vars which control Xprint on the client side: + 1. The env variable ${XPSERVERLIST} contains a list of display + identifiers (seperated by whitespace) to tell the application + where it can find the Xprt servers. Usually ${XPSERVERLIST} is set + by the profile startup scripts (e.g. /etc/profile or + /etc/profile.d/xprint.sh) using the output of "/etc/init.d/xprint + get_xpserverlist". Example: + % export XPSERVERLIST="`/etc/init.d/xprint get_xpserverlist`" + Alternativly ${XPSERVERLIST} can be set manually: + Example: + % export XPSERVERLIST="littlecat:80 bitdog:72" + instructs an application to look at the displays 80 on the machine + "littlecat" and display 72 on the machine bigdog to look for Xprt + servers. + 2. The env variable ${XPRINTER} defines the default printer used by + print applications. The syntax is either <printername> or + <printername>@<display> + Examples: + a. + % export XPRINTER=ps003 + tells an application to look for the first printer named + "ps003" on all Xprt servers. + b. + % export XPRINTER="hplaser19@littlecat:80" + tells an application to look for the printer "hplaser19" on + the Xprt display "littlecat:80". + +Note: + If ${XPRINTER} is not set the applications will examine the values + of the ${PDPRINTER}, ${LPDEST}, and ${PRINTER} env vars (in that + order). + + Q: + + How do I start Xprt ? + A: + + 1. Linux RPM installations on Mandrake/RedHat/SuSE Linux: Binary RPM + packages provided by xprint.mozdev.org (or based on the same + source :) will install /etc/init.d/xprint and related glue (see + [183][4]) automatically; after a reboot a Xprt instance will be + started at system startup and ${XPSERVERLIST} should be populated + for all users. Note that you can start/stop per-user instances + using /etc/init.d/xprint (see [184][4]), too... + 2. Debian Linux: Same as [185][1], however Debian does not support + /etc/profile.d/ - you have to add the following line to + /etc/profile (for sh/ksh/bash) to populate ${XPSERVERLIST}: + export XPSERVERLIST="`/bin/sh /etc/init.d/xprint get_xpserverlist`" + See [186]bugs.debian.org bug 171174 ('"xprint-xprintorg" should + automatically populate $XPSERVERLIST') for further details on this + issue... + 3. + a. Solaris using the "GISWxprintglue" package: + [187]http://xprint.mozdev.org/ provides a Solaris package + called "GISWxprintglue" which contains all the neccesary + configuration files and startup scripts to use Xprint; after + a reboot a Xprt instance will be started at system startup + and ${XPSERVERLIST} should be populated for all users. Note + that you can start/stop per-user instances using + /etc/init.d/xprint (see [188][4]), too... + b. Solaris using the "GISWxprint" package: + [189]http://xprint.mozdev.org/ provides a Solaris package + called "GISWxprint" which is technically identical to the + "GISWxprintglue" (see [190][3a]) but provides a Xprt binary + build from the xprint.mozdve.org sources ("GISWxprintglue" + uses the /usr/openwin/bin/Xprt binary provided by Solaris). + 4. General: Using /etc/init.d/xprint and related glue: There are + startup/shutdown scripts in xc/programs/Xserver/Xprint/etc/ to + start/stop/restart Xprt per-machine and/or per-user and to + populate the ${XPSERVERLIST} env var: + + "xc/programs/Xserver/Xprint/etc/init.d/xprint" is a script + for SystemV and Linux to start/stop/restart Xprt. The script + includes installation and usage details and can be used by + both "root" (to start Xprt for all users) or by a single + (non-priviledged, plain) user (to start Xprt instances only + for his/her own use) + + "xc/programs/Xserver/Xprint/etc/profile.d/xprint.csh" and + "xc/programs/Xserver/Xprint/etc/profile.d/xprint.sh" are + scripts for Linux (which support /etc/profile.d/ ; note that + this does not include Debian) to populate the ${XPSERVERLIST} + env var for each user. + 5. Starting Xprt "manually" (without using /etc/init.d/xprint): Set + the ${XPCONFIGDIR} env variable to the directory where Xprt can + find it's configuration data. + +WARNING + If Xprt cannot find it's configuration data it will not be able to + use printer-builtin fonts (which are defined by the model-config + in the configuration dir). Without printer-builtin fonts Xprt may + fall back to generate font glyphs from bitmap fonts (this resulted + in the MYTH that "Xprt can only print gfx fonts". This is not TRUE + - this only happens if Xprt is either misconfigured or no matching + builtin or PS Type1 font is available). + You may want to make a copy of the default configuration directory + and modify it to match your needs. + 6.

Solaris is an + exception here since it requires to start any Xserver (incl. Xprt) + setgid "root" (set-group-id "root", this is not set-user-id "root") + since the sockets/pipe files in /tmp/.X11-pipe/ and /tmp/.X11-unix/ + are only accessible for the group "root".

The + file format is identical to the PCF ("Portable Compiled Format") font + format except that the bitmap data is not provided. + Q: + + Can I use the fontserver ("xfs") with Xprt ? + A: + + You can use Xprt with the font server ("xfs") like with any other + Xserver - but it is not recommded since the font server protocol does + not allow access to the native font format and therefore disables font + download, e.g. both PS Type1 and TrueType fonts cannot be downloaded + anymore and Xprt will fall-back to embed them as bitmap glyphs in the + print job (e.g. the fonts will still appear correctly in the printout, + but the quality may be reduced since downloaded fonts are always + better than bitmap glyphs). (users of xprint.mozdev.org-release <= 006 + may see [218]xprint.mozdev.org bug 2092 if they use "xfs"; this has + been fixed in the 007 release!) + Q: + + What is a "model-config" ? + A: + + The term "model-config" refers to the subdirs in + ${XPCONFIGDIR}/${LANG}/print/models/. There subdirs contain + information about the attributes for a specific printer model or + family/class of printer models. In particular there are two kinds of + information: + * "${XPCONFIGDIR}/${LANG}/print/models/${NAME_OF_MODEL}/model-config + " this file defines a set of attributes supported by this specific + printer (-family/-class/etc.) and + * "${XPCONFIGDIR}/${LANG}/print/models/${NAME_OF_MODEL}/fonts/" - a + directory which contains a set of PMF (printer metrics file) fonts + builtin into the printer itself (actually the PMF "font" format + contains only metrics information and no glyphs). These fonts are + only available to the application after the application has + selected a printer and configured it (for developers: After + XpSetContext has been called). + + Q: + + Where can I store the default values for printers ? + A: + + XXX + Q: + + How can I create my own model-config ? + A: + + XXX + Q: + + How can I create my own PMF "fonts" ? + A: + + XXX - no solution yet, but [219]xprint.mozdev.org bug 2430 ("RFE: Need + tool to create PMF (printer metrics file) fonts") has been filed to + create a freeware tool to create such fonts. + Q: + + Where can I get more model-configs from ? + A: + + If you miss a model-config for your printer please open a bug/RFE at + [220]http://xprint.freedesktop.org/cgi-bin/bugzilla/enter_bug.cgi?prod + uct=xprint&component=Server%3A+Config%3A+model-configs (e.g. + [221]http://xprint.freedesktop.org/cgi-bin/bugzilla/enter_bug.cgi, + product "Xprint", component "Server Config: model-configs"). + Q: + + If I install Xprt &co. as "root" in the default location and don't + need to set ${XPCONFIGDIR} - where are my configuration files located + then ? + A: + + This is platform-specific, based on the "XPrintDir" Imake variable set + at build time. Default location for plain X11R6.x is + "${XProjectRoot}/lib/X11/xserver" (set at build time), but some + platforms modify "XPrintDir" to alternate locations: + * Solaris sets ${XPCONFIGDIR} to /usr/openwin/server/etc/XpConfig/ + * Linux (non-Debian) sets ${XPCONFIGDIR} to + /usr/X11R6/lib/X11/xserver/ or /etc/X11/xserver/ + * Debian Linux sets ${XPCONFIGDIR} to /usr/share/Xprint/xserver/ + +Tip + + If you don't know where the default location for ${XPCONFIGDIR} is + located try + strings -a /usr/openwin/bin/Xprt | grep XPRINTDIR + + - it may return some debug info from the binary containing the builtin + XpConfig path. + + Q: + + Are config files and/or the PMF fonts architecture dependent ? + A: + + The PMF fonts are a variant of the PCF font format, they are (like the + PCF format) architecture-independent. These fonts must be kept + together with the other model config data since they depend on the + printer model (de facto ${XPCONFIGDIR}/C/print/models/ (and/or + ${XPCONFIGDIR}/${LANG}/print/models/) should be supplied by the + printer vendors (but most people will create their own models on + demand since I doubt that any vendor except HP, Sun and + xprint.mozdev.org staff ever looked at that stuff)). Per definition + they are read-only data supplied by the vendor, but modifying them may + be usefull, too. I would say it is recommended to put treat all Xprint + files in ${XPCONFIGDIR} as read-only vendor data; admins should create + copies of this tree on demand (and/or (soft-)link some files) and set + ${XPCONFIGDIR} to the modified config data. + Q: + + Can I localise my Xprint/Xprt configuration (l10n) ? + A: + + Yes, Xprt supports localisation ("l10n") by default. Default values + for all locales are stored in ${XPCONFIGDIR}/C/print/, locale-specific + settings can be set in ${XPCONFIGDIR}/${LANG}/print/ Rules: + * Attribute pools ("${XPCONFIGDIR}/*/print/attributes/document", + "${XPCONFIGDIR}/*/print/attributes/job", + "${XPCONFIGDIR}/*/print/attributes/printer" and + "${XPCONFIGDIR}/*/print/models/*/model-config"): "document", "job" + and "printer" attribute pools and printer model-configs are + sourced first from the "${XPCONFIGDIR}/C/print/"-directory, then + they are overridden by any attributes from the locale-specific + pools (in "${XPCONFIGDIR}/${LANG}/print/"), e.g. any values set in + "${XPCONFIGDIR}/C/print/attributes/*" and + "${XPCONFIGDIR}/C/print/models/*/model-config" will automatically + apply to all other locales unless they are overridden by + locale-specific versions of these files + ("${XPCONFIGDIR}/${LANG}/print/attributes/*", + "${XPCONFIGDIR}/${LANG}/print/models/*/model-config") + * "Xprinters" (list of printers): If there is a locale-specific + ${XPCONFIGDIR}/${LANG}/Xprinters present it will be used instead + of ${XPCONFIGDIR}/C/Xprinters (e.g. values set in + ${XPCONFIGDIR}/C/Xprinters will be ignored and the values from + ${XPCONFIGDIR}/${LANG}/Xprinters will be used instead). + * Xprt will determinate the locale which should be used based on the + ${LANG}-environment vaiable at startup time. If there is no such + variable set at that time LANG="C" is assumed. + +Note: + Attribute values for paper names and orientation names refer to + builtin strings in the DDX code (which are itself based on + international standards), these cannot be changed to your own + "inventions" (it does it make sense to try to "localize" paper + names - "ISO-A4" is "ISO-A4" even in japanese/hebrew/german etc.). + Locale-spefific attribute pools can set their own, different + values - but only within the allowed range of values supported by + the DDX and printers's model-config. + + Q: + + Can I execute my own scripts to process the PostScript files generated + by Xprt ? + A: + + Yes, there are at least two possible solutions: + 1. Create your own model-config which uses a custom + "xp-spooler-command" value - the xprint.mozdev.org's "PSspooldir" + model config (see "${XPCONFIGDIR}/C/print/models/PSspooldir/" and + "${XPCONFIGDIR}/C/print/attributes/printer" and + "${XPCONFIGDIR}/C/print/Xprinters") and "PS2PDFspooldir-GS" model + config (see "${XPCONFIGDIR}/C/print/models/PS2PDFspooldir-GS/" and + "${XPCONFIGDIR}/C/print/attributes/printer" and + "${XPCONFIGDIR}/C/print/Xprinters") are good examples for that. + 2. Use an existing "model-config" (which would normally send it's + data to a printer using the default print spooler command) and + provide a custom "xp-spooler-command". + + Procedure 2. Example (using "SPSPARC2" as printer model, + /w/xp_conv as the script to execute and "myscriptprinter" as name + of the printer): + 1. Edit ${XPCONFIGDIR}/C/print/attributes/printer and add these + lines (Xprt will replace "%printer-name%" with the printer's + name, "%copy-count%" with the number of job copies, + "%job-name%" with the job's title and "%options%" with any + custom spooler options): +myscriptprinter.xp-model-identifier: SPSPARC2 +myscriptprinter.xp-spooler-command: /w/xp_conv -p %printer-name% -c %copy-count +% -t %job-name% -o "%options%" + 2.

What does that mean ? + A: + + Some versions of Xprt look up printer queues using "lpc" on Linux. In + this case "lpc" cannot be found for some reason. Solution: Find the + place where "lpc" is installed on your machine (some distributions put + it into /usr/sbin, some into /usr/bin/) and check whether your PATH + env var includes this directory.

You can have host-based, cookie-based + (a "cookie" is used like a passport) or user-based (SecureRPC or + Kerberos5) authentification. Xsecurity(7) has most of the details. + 1. No access control: . If you do not want to use access control for + Xprt then you can start it with the option "-ac" (see Xserver(1x)) + to disable the access control. Example: + % Xprt -ac -audit 4 :12 + will start Xprt with access control disabled and with auditing + enabled (e.g. the "-audit 4" option). + +WARNING + Disabling the access control will enable everyone who can access + Xprt to print on your printers (that's why the above example shows + how to use auditing, too - that you can see who does something + with Xprt...) !! + 2. Host-based access control: . Host-based access control can be + archived using /etc/X<dpy>.hosts (<dpy> == display number, e.g. + /etc/X0.hosts for display 0 (see Xserver(1x) manual page for + further details)). + + Procedure 3. Example + 1. Add the following line to `/etc/X12.hosts' (assuming you want + that the hosts 'merkur' and 'mars' should be able to access + the Xprt server running as display 12 on your host 'neptun'): +INET:merkur +INET:mars + 2. Start Xprt + 3. Verify that Xprt is correctly configured: +% export DISPLAY=neptun:12 +% xhost +access control enabled, only authorized clients can connect +INET:localhost +LOCAL: +INET:merkur +INET:mars + + Q: + + Xprt refuses to start with the message "failed to set default font + path '...' Fatal server error: could not open default font 'fixed'". + What does that mean ? + A: + + This means one or more components in the font path (set via the option + "-fp") are either... + * ... not valid + * ... contain fonts not supported by this Xserver (e.g. support has + not be compiled "in" (usually happens for TrueType (which are only + support for Solaris version of Xprt and xprint.mozdev.org releases + >= 008), OpenType (which are only supported by xprint.mozdev.org + releases 009 or higher) or F3 fonts (Sunsoft/F3 fonts are + Solaris-specific and not supported by other vendors (AFAIK)) when + support for these fonts was not enabled at build time)) + * ... no font or font alias in the font path matches the name + "fixed" + * ... an entry in fonts.dir or fonts.alias with the name "fixed" + which references a non-existing or non-readable file + + Q: + + Just copying my fonts into a directory and adding the path to my Xprt + command line didn't work - I always get "Fatal server error: could not + open default font 'fixed'". What am I doing wrong ? + A: + + Every Xserver needs an index file called fonts.dir to tell it which + fonts are available in this directory and which properties these fonts + have. + + If you are lucky there may be already a fonts.scale file which can be + used by "mkfontdir" to create the fonts.dir file. If there is no + fonts.scale then you have to create your own fonts.dir/fonts.scale + either by hand or via tools like "mkfontscale" (works for all types of + scaleable fonts), "type1inst" (for PS Type1 fonts; see + [246]http://packages.debian.org/stable/utils/type1inst.html) or + "ttmkfdir" (for TrueType fonts; see + [247]http://packages.debian.org/stable/x11/ttmkfdir.html). + Q: + + Xprt refuses to start with the message "Fatal server error: Cannot + establish any listening sockets - Make sure an X server isn't already + running". What does that mean ? + A: + + There is already a Xserver running at the display ID you have + specified to start Xprt (for example your framebuffer Xserver runs at + ":0" then Xprt can't run at the same display display). + Q: + + Xprt refuses to start with the message "Fatal server error: Failed to + establish all listening sockets". What does that mean ? + A: + + This means that the Xserver could not open one of it's sockets. Check + the permission of /tmp/.X11-pipe and /tmp/.X11-unix (on Solaris a + Xserver must run set-gid "root" to access these directories). Either + fix the permission or start Xprt with the option "-pn". Using this + option requires to access the server always with + <hostname>:<displaynum> (see Xserver(1x) manual page for the + side-effects of this option). + Q: + + Xprt refuses to start with the message "Fatal server error: could not + open default font 'fixed'" or "Fatal server error: could not open + default cursor font 'cursor'". + A: + + All Xservers at least two fonts as the minimum: One fixed-width font + ("fixed") and one font for the cursor ("cursor"). Be sure that the + font path contains these fonts. + Q: + + Xprt refuses to start with the message "Fatal server error: no screens + found". What does that mean ? + A: + + Cause: This means that Xprt could not find any printers. Either there + are no printers installed, "lpstat"/"lpc" could not find any printers + or the configuration does not contain any manual printer + configurations (see Q/A item "Which program is used by default by Xprt + to enumerate the printers on my system" for further details...). + + Solution: Two solutions: + 1. Using "PSspooldir" model: . Xprt releases from + [248]http://xprint.mozdev.org/ provide the "PSspooldir" model + config for such cases. Just edit the "Xprinters" file and add this + line: +Printer xp_ps_spooldir_tmp_Xprintjobs + this will add the pre-configured (see + ${XPCONFIGDIR}/C/print/attributes/printer) + "xp_ps_spooldir_tmp_Xprintjobs" printer which will send jobs to + the directory "/tmp/Xprintjobs/" instead to a printer queue. (This + feature was added in the xprint.mozdev.org release 007, see + [249]xprint.mozdev.org bug 2475 ("RFE: Need model-config which + spools print jobs in a predefined directory").) + 2. Manual setup (task list): . + + 1. Provide a simple "Xprinters" spec file which contains a dummy + queue. Example: +# Create "Xprinters_onlydummy" file which turns autolookup of printers +# OFF (using "Augment_Printer_List %none%") and provides one dummy +# queue called "ps_myscript" instead (using "Printer ps_myscript") +% echo "Augment_Printer_List %none%" >Xprinters_onlydummy +% echo "Printer ps_myscript" >>Xprinters_onlydummy + 2. Edit ${XPCONFIGDIR}/C/print/attributes/printer and add these + two lines: +ps_myscript.xp-model-identifier: PSdefault +ps_myscript.xp-spooler-command: /home/sanja/xprint_test/my_xprt_cat_script.sh + This means that the printer "ps_myscript" now uses the + "PSdefault" printer model and it will feed the jobs to the + script "/home/sanja/xprint_test/my_xprt_cat_script.sh" (via + stdin). Note that the absolute path is required for + "*xp-spooler-command". + 3. Start Xprt on display 18, passing the "Xprinters_onlydummy" + using the "-XpFile" option: +% Xprt -XpFile ./Xprinters_onlydummy -pn -ac -audit 4 :18 + + Q: + + "Printing itself works but the printout covers only 1/4 of the paper - + what am I doing wrong ?" + A: + + This is usually an indicator for a wrong DPI setting. The default + "PSdefault" model config uses 300 DPI but some printers only support + 600 DPI. + + Workaround: Edit ${XPCONFIGDIR}/C/print/attributes/document and + replace the line "*default-printer-resolution: 300" with + "*default-printer-resolution: 600" (Note that locale-specific settings + in ${XPCONFIGDIR}/${LANG}/print/attributes/document always override + values set in ${XPCONFIGDIR}/C/print/attributes/document.) + + Solution: Create a model-config for your printer which only contains + attributes supported by your printer ("printer-resolutions-supported" + is the attribute in the "model-config" which holds the space-seperated + list of DPI values which are supported by the printer). + Q: + + "Printing works but I get large borders/margins..." / "[Top] margin is + too small" / "Margins are wrong" / etc. + A: + + Two possible causes: + * Usually same issue as "Printing itself works but the printout + covers only 1/4 of the page"-issue: Wrong DPI. Solution: Check the + DPI value and adjust it as described in the FAQ item above. Common + DPI values for the PostScript DDX are 240, 300, 360, 400 and 600 + DPI. + * You are trying to print "US-letter" on a "DIN-A4" paper or + "DIN-A4" on "US-letter". + Solution: Check your paper settings + Note that the default papersize for Xprt depends on the locale + (e.g. on the env var ${LANG}) Xprt is running in - "en_US"&co. get + US-letter, all others use DIN-A4 (incl. german/austrian etc. + locales)). Exception from this rule: If the selected printer does + not support the default paper size it will set no default paper + size for this printer (then the application side has to make an + explicit choice). + + Q: + + Xprt prints a warning like "Xp Extension: could not find config dir + /usr/X11R6/lib/X11/C/print" - what does that mean ? + A: + + This is actually the worst case what can happen. The message indicates + that Xprt was unable to find it's configuration data. + + Solution: Two solutions are possible: + * Install the configuration data at the requested location + (/usr/X11R6/lib/X11/C/print/ in this example) + * Set the ${XPCONFIGDIR} env var to the location of the Xprt + configuration directory. + + Q: + + Xprt crashes with "Fatal server error: Beziers this big not yet + supported" What does that mean ? + A: + + This is a known issue in the X11R6.5.1 code. In rare cases some + PostScript Type1 fonts can trigger this. See "My PS Type1 font does + not work with my Xserver" ... + Q: + + "My PS Type1 font does not work with my Xserver - how can I fix this + ?" + A: + + Some PS Type1 do not work out-of-the-box with all PS Type1 font + engines - some will work with the Adobe font engine (used in Solaris + Xsun) but not with the X.org font engine (or the other way round) or + the fonts are simply broken. The following procedure will try to fix + this problem: Get the "type1fix" perl script the TeXTrace package + ([250]http://www.inf.bme.hu/~pts/textrace-latest.tar.gz) and run it + over the fonts. Example 1 (filter fonts): +# Broken PFA fonts are in broken_fonts/ +% mkdir fixed_fonts ; cd fixed_fonts +% for i in ../broken_fonts/*.pfa ; do + echo " ------- $i" ; + type1fix.pl --ofmt=pfa --infile=$i --outfile=$(basename ${i}) ; + done + + Example 2 (filter fonts and convert them to PFB on-the-fly; do not + forget to update fonts.scale and run "mkfontdir" (to update fonts.dir) + ; systems which use the Adobe font engine (like Solaris/Xsun) may + require to run "makepsres", too): +# Broken PFA fonts are in broken_fonts/ +% mkdir fixed_fonts ; cd fixed_fonts +% for i in ../broken_fonts/*.pfa ; do + echo " ------- $i" ; + type1fix.pl --ofmt=pfb --infile=$i --outfile=$(basename ${i%.pfa}.pfb) ; + done + + Q: + + I can't get it working. I have set ${DISPLAY} correctly to point to + the Xprt display and... ... What is going wrong ? + A: + + Do not set ${DISPLAY} to the Xprt server. You still need your normal + Xserver for your video card - Xprt is only for your printer(s). + Applications look up Xprt servers via the ${XPSERVERLIST} env var, NOT + via the ${DISPLAY} env var. + Q: + + When I try to print via Xprint I get the message "Fatal server error: + unable to exec '/usr/bin/lp'". What is going wrong here ? + A: + + This usually means that the spooler application "/usr/bin/lp" could + not be launched. This is usually the result when /usr/bin/lp does not + exist or cannot be executed (for example, shell scripts without the +x + (executable) flag etc.). + Q: + + The Solaris Xprt prints some error messages about PostScript fonts + like "FOOBAR not found, using Courier. CMEX0123 not found, using + Courier." etc. and uses "Courier" instead of these fonts... + A: + + Cause: The Solaris (Adobe-based) PostScript font engine requires a + "PostScript resource database" file named "PSres.upr" to use the + PostScript fonts correctly. + + Solution: Create the missing PSres.upr database. + + Procedure 5. Steps to create the missing "PSres.upr" file (task list): + 1.

Most obvious is the use of "print ddx drivers" instead of "video + ddx drivers". While a video ddx driver modifies pixels in a video + frame buffer, a print ddx driver generates "page description + language ([301]PDL)" output (such as PCL, PDF, PostScript, + SVGprint, etc.) or sends the print rendering instructions to a + platform-specific print API (like Win32/GDI). + Once a print ddx driver generates [302]PDL output, it can be sent + to a spooler (using XpuStartJobToSpooler) or retrieved by the + client (to implement functionality like "print-to-file" with + functions such as XpuStartJobToFile). + 2. Since printers support "paged" output, unlike video, a portion of + the Xp Extension supports APIs to delineate printed output into a + print job. + A "print job" in Xprint consists of one or more "documents" which + itself consists of one or more "pages". + A client starts a job sequence with XpStartJob and ends it with + XpEndJob or XpCancelJob to cancel the generation of the current + print job. Any document-specific print attributes MUST be changed + before XpStartJob. + A client starts a document sequence with XpStartDoc and ends it + with XpEndDoc or XpCancelDoc to cancel the generation of the + current document. Any document-specific print attributes MUST be + changed before XpStartDoc or after XpEndDoc (to affect the + following document). + A client starts a page sequence with XpStartPage and ends it with + XpEndPage or XpCancelPage to cancel the generation of the current + page. Any page-specific print attributes MUST be changed before + XpStartDoc or after XpEndDoc (to affect the following document). + 3. Since printers have extensive capabilities, another portion of the + Xp Extension supports APIs to manipulate "print contexts". + Once a printer is selected using the Xp Extension API, a print + context to represent it can be created. A print context embodies + the printer selected - it contains the printer's default + capabilities, selectable range of capabilities, printer state, and + generated output. Some "attributes" within the print context can + be modified by the user, and the X-Server and print ddx driver + will react accordingly. For example, the attribute + "content-orientation" can be set to "landscape" or "portrait" (if + the printer supports these values - which can be queried using the + Xprint API as well). + 4. Since printers can have "built in" fonts, the Xp Extension in the + X-Server works with the print ddx drivers to make available (for + printing only) additional fonts on a per print context basis. + When a print context is created and set for a given printer, the X + font calls may be able to access additional printer fonts. To do + this (typically), the X-Server must have access to "printer metric + files" (.pmf) that describe at minimum the metrics of the built in + fonts. + 5. Since printers can have "built in" fonts, the Xp Extension in the + X-Server works with the print ddx drivers to make available (for + printing only) additional fonts on a per print context basis. + When a print context is created and set for a given printer, the X + rendering calls use the resolution of the current page (or if not + given, the resolution of the current document or the current + resolution for this print job). The screen's resolution is INVALID + in this case. XprintUtils has the functions XpuGetResolution (to + get the current print resolution (searching page, document and job + level attributes (in that order)), XpuSetPageResolution (to set + the current page resolution), XpuSetDocResolution (to set the + current document resolution), XpuGetResolutionList (to get the + list of all resolutions supported by this printer) and + XpuFindResolution (to find a resolution in the list returned by + XpuGetResolutionList) to support getting/setting/queries of + resolutions. + When a print context is created and set for a given printer, the X + image rendering calls (such as XPutImage support scaling of + images. The Xp Extension API provides the functions + XpSetImageResolution and XpSetImageResolution to set and get an + image resolution. The scaling factor for an image printed on the + paper can simply calculated via scaling_factor = + curr_print_resolution_resolution / image_resolution where + curr_print_resolution_resolution is the value returned by a + function such as XpuGetResolution, image_resolution the resolution + passed to XpSetImageResolution and scaling_factor the resulting + scaling factor. Note that XpSetImageResolution will failure + (=FALSE) when the print DDX (for example the RASTER DDX) does not + support scaling. In that case the application has to scale the + image manually. + + Q: + + How can I get the printable area (e.g. the portion of the page on + which the printer is physically capable of placing ink) of the paper + after I have chosen a paper ? + A: + + The XpGetPageDimensions function returns the printable area and other + information about the current page geometry. Note that the page + geometry changes when the page attributes such as content-orientation + or default-medium are changed by the application. + Q: + + Do "offscreen" pixmaps work on Xprt ? + A: + + Yes, "offscreen" pixmaps are working on Xprt. + Q: + + How can I get the DPI value for the current Xprt server ? Can I use + the values from "xdpyinfo" ? + A: + + The Xprt screen resolution defines only the maximum resolution + configured for the matching DDX, the printers real DPI is obtained via + an another API (XprintUtil has a bunch of functions to get/set the + document/page resolution, see XpuGetResolutionList, + XpuFreeResolutionList, XpuGetResolution, XpuSetPageResolution, + XpuSetDocResolution and XpuFindResolution). + Q: + + Why does Xprt not offer the MIT-SHM protocol extension ? + A: + + The MIT-SHM protocol extension is partially (XShmPutImage would work, + but others like XShmGetImage and esp. XShmCreatePixmap cannot be + implemented properly) incompatible to the way how some of the Xprint + DDX are implemented. For example the PostScript, PDF, PCL and SVGprint + DDX do not rasterize any images on their side - instead they convert + the stream of X11 rendering instructions into the matching [303]PDL + instruction stream. Only the printer side will (finally) do the + rasterisation of the output image. This is the basically the same + reason why [304]XGetImage does not work for those DDXs - and functions + such as XShmCreatePixmap would be useless since drawing operations on + the shared pixmap would not be applied to the application (e.g. Xprint + client) as well. + Q: + + Does Xprint/Xprt support font rotation ? + A: + + Yes - Xprint/Xprt supports font rotation at any angle via the matrix + XLFD enhancement (this even works for printer-builtin fonts !!). For + details see the paper "New Font Technology for X11R6" by Nathan Meyers + (a copy can be found in the Xprint.org source tree under + xc/doc/hardcopy/XLFD/x11r6_fonts_94_paper.PS.gz) + + Short: The transformation-matrix for rotation can be calculated like + this: ++-- --+ +| cos(angle) sin(angle)| +| | +|-sin(angle) cos(angle)| ++-- --+ + + Examples: + 1. the following code fragment obtains a 180 degree rotated font + (matrix [-1 0 0 -1]): + ... = XLoadQueryFont(..., "-adobe-courier-bold-r-normal--*-[~24 0 0 ~24]-0-0- +m-*-iso8859-1"); + 2. the following code fragment obtains a 90 degree rotated font + (matrix [0 1 -1 0]): + ... = XLoadQueryFont(..., "-adobe-courier-bold-r-normal--*-[0 24 ~24 0]-0-0-m +-*-iso8859-1"); + + Future versions of Xprint will support the [305]STSF font API which + supports matrix transformations as well. + Q: + + When I render something on my window and call XpStartPage all the + rendered stuff is gone, I only get a white, empty paper. What is going + wrong here ? + A: + + Remember the rule that "only those drawings are printed on the paper + which were rendered between XpStartPage and XpEndPage". XpStartPage + clears the window you passed as argument, e.g. it creates a new, blank + sheet of paper where you can do your rendering stuff on. XpEndpage + then pushes the "paper sheet" to the stash of papers from the document + in process. + +Tip + + If you want to render something once for multiple or all pages: Render + on a offscreen pixmap and copy (with XCopyArea) the content to the + "paper" drawable (after calling XpStartPage) - XpStartpage only + affects the window passed as parameter. + + Q: + + What is XpStartDoc for ? + A: + + ISO 10175 and some advanced printing systems by IBM and HP had set + forth the standard that a "Job" is made up of one or more "Documents", + and each document is made up of one or more "Pages". Xprint was + designed that in a true ISO 10175 environment/implementation (lp(1) on + steroids, and with an API), Xprt can actually learn about all printers + and their capabilities though API's into the printer subsystem (vs. + using config files), map Job/Doc/Page directly into ISO 10175 + equivalents, and use APIs to view job status and kill jobs (vs. + cancel(1), lpcancel(1), lpstatus(1)). Because most applications of the + day are only printing one document per job, XpStartPage was designed + that it generates a "synthetic" XpStartDoc if it has not been called + yet. + Q: + + How does the XLFD for printer-builtin fonts look like ? / How can I + find/identify printer-builtin fonts ? + A: + + There is no special XLFD scheme for printer-builtin fonts. Instead the + xp-listfonts-modes-supported is used to define whether XListFonts and + co. return printer-builtin fonts or not. By default the attribute + looks is set to *xp-listfonts-modes-supported: + xp-list-internal-printer-fonts xp-list-glyph-fonts which defines thaht + XListFonts and co. return both printer-builtin and normal fonts. + Removing xp-list-internal-printer-fonts will make printer-builtin + fonts disappear, removing xp-list-glyph-fonts will make normal glyph + fonts disappear from font lists. + Q: + + How can I scale images using the Xprint API ? + A: + + XXX + Q: + + Can I pass my own PostScript code (fragment) to the print spooler + instead of letting Xprt's PostScript DDX generate it ? + A: + + XXX + Q: + + When I use XpPutDocumentData I get a BadValue X protocol error. Any + idea what am I doing wrong ? + A: + + XXX + Q: + + How do I use the XprintUtil library ? + A: + + XXX + Q: + + Why does the XGetImage not work for Xprt ? + A: + + There are at least three reasons why XGetImage does not work for Xprt: + 1. Most of the Xprt DDX implementations do not render itself on any + bitmaps like the framebuffer(=video) DDX do, they translate the + rendering commands into the matching commands of the printer + language (it is technically possible to implement such support for + XGetImage even for those drivers - but there are more reasons:) + 2. Xprt usually operates at high resolutions which results in very + large dimensions. If a client would request the 24bit TrueColor + bitmap data for a whole DIN-A4 page at 2400 DPI a data chunk of + ~173 megabytes would be the response. This would be more or less a + DOS(=Denial of Service) for either the client, the network and/or + the server. + 3. The printer-builtin fonts only provide metrics information - there + is no real "outline" information at that time (these fonts reside + only in the printer's ROM and are only available at the time the + printer rasterizes the incoming [306]PDL (e.g. PCL/PostScript) + data stream) which could be used to rasterize the matching glyphs + (which means: A XGetImage implementation would return image data + but glyphs rendered using the printer-builtin fonts would be + missing). + + Q: + + How to print with Xt/Athena widgets ? + A: + + There are two examples in the Xprint.org source tree which demonstrate + how to use Xprint using Athena widgets: + 1. xc/programs/xphelloworld/xpawhelloworld/ contains a simple demo + application which prints a Athena widget using the XawPrintShell + widget class. + 2. xc/programs/xphelloworld/xpxthelloworld/ contains a simple demo + application which prints a Athena widget without using a special + print widget class (however, if possible a print shell such as + XawPrintShell or XmPrintShell should be used since this is the + easier way to add print support to an Athena application). + + Q: + + How to print with Xt/Motif widgets ? + A: + + The Xprint.org source tree contains the xpxmhelloworld + (xc/programs/xphelloworld/xpxmhelloworld/) application to demonstrate + how to print using the Motif2 toolkit. + Q: + + What are the differences between normal display and Xprint display ? + A: + + XXX + Q: + + How do I scale images ? + A: + + XXX + Q: + + libXp Image scaling vs. max. request size ? + A: + + XXX + Q: + + How can I use XprintUtils ? + A: + + XXX + Q: + + How do I calculate the DPI values for Xprt DDX screens ? + A: + + XXX + Q: + + How do I find scaleable fonts ? + A: + + XXX + Q: + + How do I find printer-builtin fonts ? + A: + + XXX + Q: + + The XLFD for Printer-builtin fonts look like bitmap fonts - is that + bad ? + A: + + No, this is not "bad". The XLFD of a printer-builtin font only looks + like a bitmap font since the *.pmf (Printer metrics file) format is a + PCF file format variant (the DPI values in the XLFD AFAIK specifies + the resolution which was used for generating the metrics) - however + this does not change the fact that the printer-builtin fonts are + outline scaleable fonts these fonts reside in the printer's ROM). + Q: + + When printing using the XawPrintShell/XmPrintShell print shells my + PostScript output is always corrupt. What am I doing wrong ? + A: + + Make sure the widgets (such as text input widgets) have the (blinking) + cursor turned-off. Setting the XmNcursorPositionVisible, to False + usually solves the problem (for Motif2 widgets). Example: +... +XtSetArg(args[n], XmNcursorPositionVisible, False); +... + + Q: + + When printing using the XawPrintShell/XmPrintShell print shells I + always get a grey/dithered background on paper. Any idea how to change + that to "white" ? + A: + + XXX + Q: + + Are there any caveats/suggestions when printing via Xt/Motif2 widgets + ? + A: + + There are a couple of Xt resources which may likely differ from the + normal values (e.g. those values used for a video Xserver): + + Core class level + + XmNbackground resource + The application will probably want to set the + XmNbackground resource to "white" to match the default + paper color. + + XmNborderWidth resource + The application will probably want to set the + XmNborderWidth resource to "0" (usually the default + value) to avoid that a black border appears around the + widget. + + XmPrimitive class + + XmNshadowThickness and XmNhightlightThickness resources + The application will probably want to set + XmNshadowThickness and XmNhightlightThickness to "0" + (usually the default value) to avoid 3D border effects on + the printout (depends on application and author's + preference... :-)). + + XmText and XmTextField classes + + XmNcursorPositionVisible resource + The application will probably want to set + XmNcursorPositionVisible to False to avoid that the + cursor is visible on printouts (and to avoid problems + with some nasty implementation details which may cause + corrupted PostScript output). + + XmNscrollHorizontal and XmNscrollVertical resources + The application will probably want to set the + XmNscrollHorizontal and XmNscrollVertical resources to + False to suppress printing of scrollbars (on paper + "scrolling" is replaced with "pagination" except for rare + exceptions (like 1:1 WYSIWYG-printing)). + + XmNmarginWidth and XmNmarginHeight resources + The application will probably want to recalculate the + XmNmarginWidth and XmNmarginHeight resources based on the + (far) higher print resolution (or reverse: set them to + "0" - depending on what style matches the application + needs better...). + + XmLabel class + + XmNmarginTop, XmNmarginBottom, XmNmarginRight, XmNmarginLeft, + XmNmarginWidth, XmNmarginHeight and XmNalignment + resources + The application will probably want to use different value + for XmLabel class's XmNmarginTop, XmNmarginBottom, + XmNmarginRight, XmNmarginLeft, XmNmarginWidth, + XmNmarginHeight and XmNalignment resources. These + resources are mainly usefull when the widget holds a + border, highlight or shadow of some kind.

GENERAL +- Q: What is "Xprint" ? + A: In short, "Xprint" is an advanced printing system which enables X11 + applications to use devices like printers, FAX or create documents in + formats like PostScript or PDF. + + In long, "Xprint" is a very flexible, extensible, scaleable, client/server + print system based on ISO 10175 (and some other specs) and the X11 + rendering protocol. + Using Xprint an application can search, query and use devices like + printers, FAX machines or create documents in formats like PDF. + In particular, an application can seek a printer, query supported + attributes (like paper size, trays, fonts etc.), configure the printer + device to match it's needs and print on it like on any other X device + reusing parts of the code which is used for the video card Xserver... + +- Q: Where can I get Xprint/Xprt from ? + A: Xprint is client-server based, therefore two answers: + - The server side is available by default on Solaris[1] and HP-UX (Xfree86 + ships a "Xprt" binary, but that is broken and the server config files + are missing, too). + For those platforms who do not have a (working) Xprt server the you + can get source, binary tarballs and Linux RPMs from + http://xprint.mozdev.org/ , Debian Linux has a package based on the + same sources (see http://packages.qa.debian.org/x/xprint-xprintorg.html) + - The client-side Xprint support library (libXp.so) is available on all + X11 platforms >=R6.4, including Linux, Solaris, HP-UX, AIX etc. + if you do not have it you can build it from the sources available at + http://xprint.mozdev.org/ + + [1]=(for Solaris >= 2.7 xprint.mozdev.org provides the "GISWxprintglue" + and "GISWxprint" packages (available from + http://xprint.mozdev.org/download.html) which provides a single-step + drop-in way to configure and start Xprint at system startup and/or + per-user for all applications and users (the package provides only + startup scripts and some config data and uses the Xprt binary provided + with Solaris (/usr/openwin/bin/Xprt)) + +- Q: What is "Xprt" ? + A: Xprt is the server-side of Xprint. It's just like any other Xserver - it + uses only an other kind of output device (printer instead of framebuffer) + and implements an extra X11 extension ("XpExtension") to handle the + special features/requirements of a "paged device"(=printer etc.). + +- Q: "Why do some people like Xprint ?" / "What are the advantages of Xprint ?" + A: - Xprint allows an application to query what features (paper size, trays, + orientation, resolutions, plexes, fonts and much more) a printer supports. + For example it is avoidable that a user accidently prints DIN-A4 on a + DIN-A0 poster printer (the print dialog would only offer DIN-A0 as paper + size, e.g. offers only choices which are valid for this printer). + - Server-side, localizeable configuration - changes to the server + config apply to all users without the need to change/updating anything + on the user side (the user may still start his/her own Xprt instance + using his/her preferred configuration). + - Small footprint - ideal for for mobile devices (client side does not + need to process any fonts - that's the job of the server side) + - API not restriced to PostScript (X11R6.5.1 comes with PCL and Raster + implementations - and PDF/G3-FAX/SVG would be possible without problems) + - Scaleable - Xprint can use as many Xprt servers as the user/admin wants + - "Xprint is designed for the enterprise", e.g. Xprint was designed to + match the needs of large company networks. + - Automatic font handling - font download or the existence of + printer-builtin fonts is automagically handled by Xprt - the application + does not need to know/handle any details (but the application can + optionally get information and control the usage of printer builtin + fonts) + - You can print anything what you can render on the framebuffer(=video + card) Xserver + - Existing code can be reused 1:1 for printing - which means reduced + development costs + - Easy support for I18N (internationalization) - you simply render any + fonts in any language with Xprint + - Network-transparent design - Client can use local or remote Xprt servers + like any other Xserver + - Uses the X11 protocol - easy adoption of existing code to implement + printer support. And all the network goodies like firewall proxies, + compressors etc. can be used for Xprint without modifications. + - Security: Xprint can use all authentification schemes available in X11 + (like Kerberos5, SecureRPC, MIT-MAGIC-COOKIE or host-based + authentification). + - Enhachements on the server side (Xprt) to not require the change of + client-side code. + - Optimized job output (like the PostScript created by the PostScript DDX) + is usually a lot smaller than the PS code created by other PostScript + engines. + +- Q: Why do some people dislike Xprint? + A: There are a few common misconceptions about Xprint. + Let's take a look some of these "myths", some background - and the facts: + + - Myth: "Xprint prints just a XWD dump of the Xserver bitmap" + Fact: Whoever says Xprint simply does an "xwd"-like dump is wrong. + + In short, Xprint _currently_ (X11R6.5.1) supports *four* drivers: + 1) X to native Postscript + 2) X to native PCL5 + 3) X to native PCL3 + 4) X to a raster which is then feed to something like xpr to + create PS or PCL5 wrapped rasters. + + In long, the original X Print Service ("XPS") was attempted + during CDE 1.0, and they only got so far as the "raster" driver. + + As CDE 2.0 came around, Bob Schiefler and others at the X + Consortium agreed that the X Consortium would work on a X to + native PS Level 2 driver and HP would work on a X to native + PCL5 driver. + + It was probably the CDE 1.0 effect that left many people with + the impression that Xprint is all about xwd-like window dumps. + NO! Xprint has native PostScrpt and PCL5 printing and more + drivers (like a PDF DDX etc.) are in the development. + + - Myth: "Xprint cannot handle non-'ISO Latin 1' chars" + - Fact: Xprint can print any chars incl. those required for MathML, + Hebrew, Arabic, Japanese etc. etc. + For example - the Xprint module for Mozilla5 is the only print + module which can proprtly print MathML. + + - Myth: "Xprint uses a 1024x768 screen resolution to render the stuff on + the paper - therefore it will never be able to do high-resolution + stuff" + Fact: Xprt uses the screen resolution requested by the application or + the printers default resolution. + For example a 300 DPI printer which supports paper sizes up to + DIN-A4 will get a screen with 3300x3300 pixels (screen width and + height are usually equal to support per-page changes in the + orientation (potrait/landscape etc.), the window size would be + 2400x3149 for "portrait" orientation) - and larger resolutions + will result in larger screens. + + - Myth: "Xprint prints only graphics(=bitmap/gfx) fonts" + - Fact: In short, Xprt supports printer-builtin fonts and can + download fonts to the printer if they do not exist on the printer. + + In long, this myth seems to have it's root in a _feature_ of + Xprt which can - if Xprt gets misconfigured - disable the use of + printer-builtin fonts and the ability to download fonts. + + Xprt's PostScript and PCL DDX have the _unique_ feature to create + font glyphs from bitmap fonts if they are not available as + printer-builtin fonts nor as PostScipt Type1 fonts. However this + is the fallback - the _last_ option used by Xprt. Used if + everything else fails. + But when someone does not pass any PS Type1 fonts with the font + path nor configures a printer model-config (which contains a + description of the features&fonts supported by the printer) Xprt + will never have a chance to use them. And if everything else + fails it has no other option than using what has been left - the + bitmap fonts... + + - Myth: "Xprint does not support pages sizes larger than DIN-A4" + Fact: There is no such limitation. + The only limit is the 16bit coordinate system of the X11 + protocol - which is large enougth that Xprint can support paper + sizes _larger_ than DIN-A0 oversize papers. There is no problem + with creating your own monster-size DIN-A0 posters using + Xprint-based applications. + + - Myth: "Xprint does not support rotated text" + Fact: Xprint and all it's drivers support the X11 matrix XLFD + enhancement introduced in X11R6. Fonts can be rotated at any + angle. Take a look at the "SOFTWARE DEVELOPMENT" section in this + FAQ for examples... + +- Q: Does Xprint support anti-aliased fonts ? + A: Question back: When do we need anti-aliased fonts ? + Anti-aliasing is a "hack" to work around the limitations caused by the + low resolution of monitors - they usually operate between 72 DPI and + 150 DPI. + But Xprint operates on printers where the usual _minimum_ resolution is + 300 DPI (today's normal office printers support resolutions ranging from + 300 DPI up to 2400 DPI depending on the model; most common is 600 DPI). + Anti-aliasing at those resolutions is not required anymore. + Additionally many printers support their own font anti-aliasing at lower + resolutions which is far better and faster than it could be "done" on the + client side. + +- Q: How can I check if Xprint is working and should be used ? + A: Check whether the ${XPSERVERLIST} env var is set or not. + If ${XPSERVERLIST} is set then Xprint is available and should be used. + +- Q: How can I view PS(=PostScript) files ? + A: - On Unix/Linux (general): + - GhostScript ("gs") and GhostView ("gv") + - Solaris: + - /usr/dt/bin/sdtimage (DPS-based image viewer for CDE) + - /usr/openwin/bin/pageview (DPS-based image viewer for OpenWindows) + +- Q: How can I view PCL files ? + A: XXX - http://xprint.mozdev.org/bugs/show_bug.cgi?id=2261 has been filed + for that issue. + +- Q: How does Xprt find fonts ? + A: Lookup-rule for Xprt's PostScript DDX to find fonts: + 1. Printer-builtin fonts (defined by the fonts/-dir in the model-config) + 2. PostScript fonts (will be downloaded via generated print job) + 3. GFX-fonts build from X11 scaleable fonts + 4. GFX-fonts build from X11 bitmap fonts + +- Q: How can I print TrueType fonts with Xprint ? + A: 1. Linux Xprt build from http://xprint.mozdev.org 's source supports + TrueType fonts out-of-the-box (starting with the 008 development tree; + xprint.mozdev.org's releases <= 007 do not support TrueType fonts) and + and does not require any special actions. + 2. Sun's Xprt on Solaris (/usr/openwin/bin/Xprt) has TrueType font + support out-of-the-box and does not require any special actions + 3. You can setup a TTF-aware X font server ("xfs", see xfs(1)) with the + matching TrueType fonts and add the font server location to Xprt's font + path. + 4. Sourceforge has a TrueType to PostScript Type 1 converter project, + see http://ttf2pt1.sourceforge.net/download.html + You may convert the TTF files into PT1 files that Xprt can download them + to the printer on demand... + +- Q: What does "DDX" mean ? + A: DDX is a short term for "Device Dependent X" - the device-specific layer + of a Xserver ("DIX"(="Device Independent X") is the counterpart). + +- Q: What does "DIX" mean ? + A: DIX is a short term for "Device Independent X" - the non-device specific + code of a Xserver ("DDX"(="Device Dependent X") is the counterpart). + +- Q: I have twenty printers installed on my system - but Xprt only shows two + screens. Where are all the other printers ? + A: A Xprt screen does not represent a single printer. A Xprt screen + represents a single DDX (currently supported are PostScript, PCL3/5 color, + PCL mono and "raster" output(=1bit deep bitmap). + +- Q: Which platforms support Xprint ? + A: All platforms which support X11 >= R6.4 can use Xprint. The client side + (libXp.so) is available on Linux/FreeBSD(=Xfree86), Solaris, HP-UX and AIX + and the Xprt server side is available by default on Solaris and HP-HX + (Xfree86 shipps with a Xprt binary - but that is broken and unuseable). + The client-side extension library (libXp.so) can be compiled on any + platform, the Xprt server needs minor adjustments for the specific + platforms... + If your platform does not have Xprint (client-side and/or server-side) + you can get the sources from http://xprint.mozdev.org/ + +- Q: I have the broken Xfree86 Xprt binary on my system. Do I need a new + version of "libXp.so" (the client side X11 extension library for Xprint), + too ? + A: No, the libXp.so shared library shipped with Xfree86 or build from + Xfree86 sources is not broken, only the server side ("Xprt") is buggy. + There is no need to replace the library. + +- Q: Which spelling is correct - "Xprint", "XPrint", "Xprinter" or Xprt" ? + A: "Xprint" is the correct one - "XPrint" is just a typo, "Xprinter" is a + complety different product not related to X11/Xprint and "Xprt" is only + the "X11 print server"(=the server side of Xprint). + +- Q: Which applications support Xprint ? + A: There are various applications which support Xprint: + - Motif/LessTif (full framework incl. special widgets like XmPrintShell) + - Common Desktop Environment (CDE) 2.x + - Mozilla + - Eclipse + - KDE/Qt support is comming is planned for the end of Dec/2002 + - StarOffice 5.x + etc. + +- Q: Is "Xprint" "mozilla"-only (I saw that it's hosted by mozdev.org) ? + A: No, Xprint is a general-purpose print API based on the X11 API used by + many applications (mozdev.org is just hosting the development area, but + this does not mean the project is limited to mozilla... :) + +- Q: Under which license is the source code from xprint.mozdev.org distributed + under ? + A: That's the plain "MIT" license, the same as used by Xfree86.org and X.org: + -- snip -- + Copyright (c) <year> <copyright holders> + + Permission is hereby granted, free of charge, to any person obtaining a copy of this software + and associated documentation files (the "Software"), to deal in the Software without + restriction, including without limitation the rights to use, copy, modify, merge, publish, + distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the + Software is furnished to do so, subject to the following conditions: + + The above copyright notice and this permission notice shall be included in all copies or + substantial portions of the Software. + + THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING + BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + NONINFRINGEMENT.

USAGE +- Q: How do I configure Xprint on the client side ? + A: There are two env vars which control Xprint on the client side: + 1. The env variable ${XPSERVERLIST} contains a list of display identifiers + (seperated by whitespace) to tell the application where it can find + the Xprt servers. + Usually ${XPSERVERLIST} is set by the profile startup scripts (e.g. + /etc/profile or /etc/profile.d/xprint.sh) using the output of + "/etc/init.d/xprint get_xpserverlist". + Example: + % export XPSERVERLIST="`/etc/init.d/xprint get_xpserverlist`" + Alternativly ${XPSERVERLIST} can be set manually: + Example: + % export XPSERVERLIST="littlecat:80 bitdog:72" + instructs an application to look at the displays 80 on the machine + "littlecat" and display 72 on the machine bigdog to look for Xprt + servers. + 2. The env variable ${XPRINTER} defines the default printer used by print + applications. The syntax is either <printername> or + <printername>@<display> + - Examples: + 1. % export XPRINTER=ps003 + tells an application to look for the first printer named "ps003" on + all Xprt servers. + 2. % export XPRINTER="hplaser19@littlecat:80" + tells an application to look for the printer "hplaser19" on the Xprt + display "littlecat:80". + * If ${XPRINTER} is not set the applications will examine the values of + the ${PDPRINTER}, ${LPDEST}, and ${PRINTER} env vars (in that order). + +- Q: How do I start Xprt ? + A: 1. Linux RPM installations on Mandrake/RedHat/SuSE Linux: + Binary RPM packages provided by xprint.mozdev.org (or based on the same + source :) will install /etc/init.d/xprint and related glue (see [4]) + automatically; after a reboot a Xprt instance will be started at system + startup and ${XPSERVERLIST} should be populated for all users. + Note that you can start/stop per-user instances using /etc/init.d/xprint + (see [4]), too... + + 2. Debian Linux: + Same as [1], however Debian does not support /etc/profile.d/ - you have + to add the following line to /etc/profile (for sh/ksh/bash) to populate + ${XPSERVERLIST}: + -- snip -- + export XPSERVERLIST="`/bin/sh /etc/init.d/xprint get_xpserverlist`" + -- snip -- + See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=171174 + ('"xprint-xprintorg" should automatically populate $XPSERVERLIST') for + further details on this issue... + + 3a. Solaris using the "GISWxprintglue" package: + http://xprint.mozdev.org/ provides a Solaris package called "GISWxprintglue" + which contains all the neccesary configuration files and startup scripts + to use Xprint; after a reboot a Xprt instance will be started at system + startup and ${XPSERVERLIST} should be populated for all users. + Note that you can start/stop per-user instances using /etc/init.d/xprint + (see [4]), too... + + 3b. Solaris using the "GISWxprint" package: + http://xprint.mozdev.org/ provides a Solaris package called "GISWxprint" + which is technically identical to the "GISWxprintglue" (see [3a]) but + provides a Xprt binary build from the xprint.mozdve.org sources + ("GISWxprintglue" uses the /usr/openwin/bin/Xprt binary provided by Solaris). + + 4. General: Using /etc/init.d/xprint and related glue: + There are startup/shutdown scripts in xc/programs/Xserver/Xprint/etc/ + to start/stop/restart Xprt per-machine and/or per-user and to populate the + ${XPSERVERLIST} env var: + - "xc/programs/Xserver/Xprint/etc/init.d/xprint" is a script for SystemV + and Linux to start/stop/restart Xprt. The script includes installation + and usage details and can be used by both "root" (to start Xprt for all + users) or by a single (non-priviledged, plain) user (to start Xprt + instances only for his/her own use) + - "xc/programs/Xserver/Xprint/etc/profile.d/xprint.csh" and + "xc/programs/Xserver/Xprint/etc/profile.d/xprint.sh" are scripts for + Linux (which support /etc/profile.d/ ; note that this does not include + Debian) to populate the ${XPSERVERLIST} env var for each user. + + 5. Starting Xprt "manually" (without using /etc/init.d/xprint): + Set the ${XPCONFIGDIR} env variable to the directory where Xprt can find + it's configuration data. + | WARNING: If Xprt cannot find it's configuration data it will not be + | able to use printer-builtin fonts (which are defined by the + | model-config in the configuration dir). Without printer-builtin fonts + | Xprt _may_ fall back to generate font glyphs from bitmap fonts (this + | resulted in the MYTH that "Xprt can only print gfx fonts". This is not + | _TRUE_ - this only happens if Xprt is either misconfigured or no + | matching builtin or PS Type1 font is available). + You may want to make a copy of the default configuration directory and + modify it to match your needs. + + Starting Xprt is just as easy as starting any other Xserver: + % Xprt :12 + will start Xprt on display 12 (e.g. set ${XPSERVERLIST} to ":12" or + "myhostname:12". + + You may want to copy your framebuffer Xserver's font path to be able to + print all fonts which can be displayed on that Xserver. + % Xprt -fp $(xset q | awk "/Font Path:/ { i=1 ; next } i==1 { print \$0 ; i=0 }") :12 + + Notes: + - The /etc/init.d/xprint has a more advanched filtering scheme based on + regex patters to "accept" and/or "reject" font paths + - 'xset q | awk "/Font Path:/ { i=1 ; next } i==1 { print \$0 ; i=0 }"' + may be too simple-minded if your Xserver does not support TrueType + fonts. The following statemement is better in this case since it + filters the font path and removes all path elements which have TrueType + fonts (*.ttf, *.TTF) or TrueType font collections (*.ttc, *.TTC) in + "fonts.dir": + -- snip -- + % xset q | awk "/Font Path:/ { i=1 ; next } i==1 { print \$0 ; i=0 }" | + tr "," "\n" | while read i ; do \ + if [ "$(cat ${i}/fonts.dir | egrep -i "ttf|ttc" 2>/dev/null)" == "" ] \ + ; then echo $i ; fi ; done | (fontpath="" ; fpdelim=""; while read i ; \ + do fontpath=${fontpath}${fpdelim}${i} ; fpdelim="," ; done ; echo \ + $fontpath) + -- snip -- + - It may be easier to just feed all available font paths to Xprt + (BTW: mozilla 1.0 had a bug in that case which resulted in the problem + that it used many many bitmap fonts in that case - this has been fixed + for 1.0.1 and Netscape 7 (that's the reason why the quickguides for + hebrew/cyrillic use the "Xp_dummyfonts" fonts instead of + /usr/openwin/lib/X11/fonts/misc/ - to avoid that Mozilla finds bitmap + fonts for the same locale). + The following "small" one-liner finds all fonts (except printer builtin + fonts): + -- snip -- + % find /usr/openwin -name fonts.dir | while read i ; do echo + ${i%/fonts.dir} ; done | fgrep -v "models/" + -- snip -- + Plug it into the filter above to remove the Truetype fonts and you are + "done"... :) + + See TROUBLESHOOTING if you run into problems... + +- Q: How can I get a list of printers managed by Xprint ? + A: The tool "xplsprinters" is designed for that purpose. It can deliver both + list of printers and attributes supported for a specific list of printers. + Use % xplsprinters -h # to obtain usage information. + Example: + - Get list of available printers: + -- snip -- + % xplsprinters + printer: hplaserjet001@castor:19 + printer: hpcolor001@castor:19 + printer: laser1@jason:5 + printer: david_dj01@jason:5 + -- snip -- + - Get information about the supported attrbites of printer "ps002": + -- snip -- + % xplsprinters -printer ps002 -l + printer: ps002@castor:18 + comment= + model-identifier=HPDJ1600C + default-medium=iso-a4 + default-input-tray= + medium-source-sizes-supported=iso-a4 false 6.35 203.65 6.35 290.65 + medium-source-sizes-supported=na-letter false 6.35 209.55 6.35 273.05 + default-printer-resolution=300 + resolution=300 + default_orientation= + orientation=portrait + orientation=landscape + default_plex= + plex=simplex + -- snip -- + +- Q: How can I start Xprt at boot time ? + A: "xc/programs/Xserver/Xprint/etc/init.d/xprint" is a script for SystemV + and Linux to start/stop/restart Xprt at system startup (e.g. per-machine) + or for a single user (e.g. per-user). + The script includes installation and usage details. + +- Q: How can I start Xprt per-user ? + A: "xc/programs/Xserver/Xprint/etc/init.d/xprint" is a script for SystemV + and Linux to start/stop/restart Xprt at system startup (e.g. per-machine) + or for a single user (e.g. per-user). + The script includes installation and usage details. + +- Q: How can I start Xprt only for one application ? + A: Create your own version/copy of /etc/init.d/xprint and modify it to fit + your requirements and then make sure that you issue a + "my_xprint_startscript start" before starting the application and a + "my_xprint_startscript stop" after leaving the application. + +- Q: How can I filter the font path which should be passed to Xprt for + certain fonts ? + A: XXX + +- Q: How can I manage access control to the Xprt server ? + A: Access control to Xprt is not differently as to any other Xserver and + can be handled in various ways - like per-cookie + (using MIT-MAGIC-COOKIE-1 authentification), + per-user (using SUN-DES-1 or MIT-KERBEROS-5 auth., see (see xhost(1))) + and/or per-machine (using "xhost" (see xhost(1)) and/or + /etc/X<dpy>.hosts (<dpy> == display number, e.g. /etc/X0.hosts for + display 0) (see Xserver(1))) + Consult manual pages Xsecurity(7), xhost(1), Xserver(1) etc. for further + details. + +- Q: How can I log access to the Xprt server ? + A: Logging access to Xprt can be done using the standard Xserver auditing, + see the Xserver(1) manual page, option "-audit" + +- Q: Does it require "root" permissions to use Xprt/Xprint ? + A: No, both Xprint clients and Xprint server(s) do not require root rights + to work. + Xprint clients are handled like any other X11 application and the Xprt + servers can run without any special requirements. + Solaris is an exception here since it requires to start any Xserver + (incl. Xprt) setgid "root" (set-group-id "root", this is _not_ + set-user-id "root") since the sockets/pipe files in /tmp/.X11-pipe/ and + /tmp/.X11-unix/ are only accessible for the group "root". + The workaround is to start Xprt with the option "-pn"; therefore even + Xprt server binaries which are not setgid "root" can run without + problems). + +- Q: How can I see the attributes of a printer managed by Xprint ? + A: "xplsprinters -printer myprinter004 -l" will do the job for printer + "myprinter004".

There subdirs contain information + about the attributes for a specific printer model or family/class of + printer models. In particular there are two kinds of information: + - "${XPCONFIGDIR}/${LANG}/print/models/${NAME_OF_MODEL}/model-config" + this file defines a set of attributes supported by this specific printer + (-family/-class/etc.) + and + - "${XPCONFIGDIR}/${LANG}/print/models/${NAME_OF_MODEL}/fonts/" - a + directory which contains a set of PMF (printer metrics file) fonts + builtin into the printer itself (actually the PMF "font" format + contains only metrics information and no glyphs). + These fonts are only available to the application _after_ the + application has selected a printer and configured it (for developers: + After |XpSetContext()| has been called). + +- Q: Where can I store the default values for printers ? + A: XXX + +- Q: How can I create my own model-config ? + A: XXX + +- Q: How can I create my own PMF "fonts" ? + A: XXX - no solution yet, but + http://xprint.mozdev.org/bugs/show_bug.cgi?id=2430 ("RFE: Need tool to + create PMF (printer metrics file) fonts") has been fixed to create a + freeware tool to create such fonts. + +- Q: Where can I get more model-configs from ? + A: If you miss a model-config for your printer please open a bug/RFE at + http://xprint.mozdev.org/bugs/enter_bug.cgi?product=xprint&component=Server%3A+Config%3A+model-configs + (e.g. ttp://xprint.mozdev.org/bugs/ , product "Xprint", component + "Server Config: model-configs"). + +- Q: If I install Xprt&co. as "root" in the default location and don't need + to set ${XPCONFIGDIR} - where are my configuration files located then ? + A: This is platform-specific, based on the "XPrintDir" Imake variable set + at build time. Default location for plain X11R6.x is + "${XProjectRoot}/lib/X11/xserver" (set at build time), but some + platforms modify "XPrintDir" to alternate locations: + - Solaris sets ${XPCONFIGDIR} to /usr/openwin/server/etc/XpConfig/ + - Linux (non-Debian) sets ${XPCONFIGDIR} to /usr/X11R6/lib/X11/xserver/ + or /etc/X11/xserver/ + - Debian Linux sets ${XPCONFIGDIR} to /usr/share/Xprint/xserver + * If you don't know where the default location for ${XPCONFIGDIR} is + located try + % strings -a /usr/openwin/bin/Xprt | grep XPRINTDIR # - it _may_ + return some debug info from the binary containing the builtin XpConfig + path. + +- Q: Are config files and/or the PMF fonts architecture dependent ? + A: The PMF fonts are AFAIK a variant of the PCF font format, they are + (like the PCF format) architecture-independent. + These fonts must be kept together with the other model config data since + they depend on the printer model (de facto + ${XPCONFIGDIR}/C/print/models/ (and/or + ${XPCONFIGDIR}/${LANG}/print/models/) should be supplied by the printer + vendors (but most people will create their own models on demand since + I doubt that any vendor except HP, Sun and xprint.mozdev.org staff ever + looked at that stuff)). + Per definition they are read-only data supplied by the vendor, but + modifying them may be usefull, too. + I would say it is recommended to put treat all Xprint files in + ${XPCONFIGDIR} as read-only vendor data; admins should create copies of + this tree on demand (and/or (soft-)link some files) and set + ${XPCONFIGDIR} to the modified config data. + +- Q: Can I localise my Xprint/Xprt configuration ? + A: Yes, Xprt supports localisation ("l10n") by default. Default values for + all locales are stored in ${XPCONFIGDIR}/C/print/, locale-specific + settings can be set in ${XPCONFIGDIR}/${LANG}/print/ + Rules: + - Attribute pools + ("${XPCONFIGDIR}/*/print/attributes/document", + "${XPCONFIGDIR}/*/print/attributes/job", + "${XPCONFIGDIR}/*/print/attributes/printer" and + "${XPCONFIGDIR}/*/print/models/*/model-config"): + "document", "job" and "printer" attribute pools and printer + model-configs are sourced first from the + "${XPCONFIGDIR}/C/print/"-directory, then they are overridden by any + attributes from the locale-specific pools (in + "${XPCONFIGDIR}/${LANG}/print/"), e.g. any values set in + "${XPCONFIGDIR}/C/print/attributes/*" and + "${XPCONFIGDIR}/C/print/models/*/model-config" will automatically + apply to all other locales unless they are overridden by + locale-specific versions of these files + ("${XPCONFIGDIR}/${LANG}/print/attributes/*", + "${XPCONFIGDIR}/${LANG}/print/models/*/model-config") + - "Xprinters" (list of printers): + If there is a locale-specific ${XPCONFIGDIR}/${LANG}/Xprinters present + it will be used instead of ${XPCONFIGDIR}/C/Xprinters (e.g. values set + in ${XPCONFIGDIR}/C/Xprinters will be ignored and the values from + ${XPCONFIGDIR}/${LANG}/Xprinters will be used instead). + - Xprt will determinate the locale which should be used based on the + ${LANG}-environment vaiable at startup time. If there is no such + variable set at that time LANG="C" is assumed. + * Notes: + - Attribute values for paper names and orientation names refer to + builtin strings in the DDX code (which are itself based on + international standards), these cannot be changed to your own + "inventions" (it does it make sense to try to "localize" paper names - + "ISO-A4" is "ISO-A4" even in japanese/hebrew/german etc.). + Locale-spefific attribute pools can set their own, different values - + but only within the allowed range of values supported by the DDX and + printers's model-config. + +- Q: Can I execute my own scripts to process the PostScript files generated + by Xprt ? + A: Yes, there are at least two possible solutions: + 1. Create your own model-config which uses a custom "xp-spooler-command" + value - the xprint.mozdev.org's "PSspooldir" model config (see + "${XPCONFIGDIR}/C/print/models/PSspooldir/" and + "${XPCONFIGDIR}/C/print/attributes/printer" and + "${XPCONFIGDIR}/C/print/Xprinters") is a good example for that. + 2. Use an existing "model-config" (which would normally send it's data to + a printer using the default print spooler command) and provide a + custom "xp-spooler-command". + Example (using "SPSPARC2" as printer model and "myscriptprinter" as + name of the printer): + 1. Edit ${XPCONFIGDIR}/C/print/attributes/printer and add these lines + (Xprt will replace "%printer-name%" with the printer's name, + "%copy-count%" with the number of job copies, "%job-name%" with the + job's title and "%options%" with any custom spooler options): + -- snip -- + myscriptprinter.xp-model-identifier: SPSPARC2 + myscriptprinter.xp-spooler-command: -printer %printer-name% -copies %copy-count% -title %job-name% -options "%options%" + -- snip -- + 2. Edit ${XPCONFIGDIR}/C/print/Xprinters and append this line: + -- snip -- + Printer myscriptprinter + -- snip -- + +- Q: How can I disable "spooldir_tmp_Xprintjobs" printer target ? + A: Edit ${XPCONFIGDIR}/C/print/Xprinters and remove or comment-out the line + "Printer spooldir_tmp_Xprintjobs". + Note that Xprt will _NOT_ start if this printer has been removed/disabled + and no other print queue is available (e.g. if "spooldir_tmp_Xprintjobs" + is the only printer target available). + +4. TROUBLESHOOTING +- Q: Xprt refuses to start with the message "sh: lpc: command not found" on + my Linux machine. What does that mean ? + A: Xprt looks up printers using "lpc" on Linux. In this case "lpc" cannot be + found for some reason. + Solution: + Find the place where "lpc" is installed on your machine (some + distributions put it into /usr/sbin, some into /usr/bin) and check + whether your PATH env var includes this directory. + Example (if "lpc" is located in /usr/sbin): + % which lpc + /usr/sbin/lpc + % export PATH=$PATH:/usr/sbin + # Start Xprt ... + % Xprt <your-options-come-here> + +- Q: When the application (=client side) tries to connect to the Xprt + (Xserver) side it fails with a + -- snip -- + Xlib: connection to "meridian:52.0" refused by server + Xlib: Client is not authorized to connect to Server + -- snip -- + What does that mean ? + A: X11 implements access control. You can have host-based, cookie-based (a + "cookie" is used like a passport) or user-based (SecureRPC or Kerberos5) + authentification. Xsecurity(7) has most of the details. + a. No access control: + If you do not want to use access control for Xprt then you can start it + with the option "-ac" (see XSERVER(1)) to disable the access control. + Example: + % Xprt -ac -audit 4 :12 + will start Xprt with access control disabled and with auditing enabled + (e.g. the "-audit 4" option). + WARNING: Disabling the access control will enable _everyone_ who can + access Xprt to print on your printers (that's why the above example + shows how to use auditing, too - that you can see who does something + with Xprt...) !! + + b. Host-based access control: + Host-based access control can be archived using /etc/X<dpy>.hosts + (<dpy> == display number, e.g. /etc/X0.hosts for display 0 (see + Xserver(1) manual page for further details)). + Example: + 1. Add the following line to `/etc/X12.hosts' (assuming you want that + the hosts 'merkur' and 'mars' should be able to access the Xprt + server running as display 12 on your host 'neptun'): + -- snip -- + INET:merkur + INET:mars + -- snip -- + 2. Start Xprt + 3. Verify that Xprt is correctly configured: + -- snip -- + % export DISPLAY=neptun:12 + % xhost + access control enabled, only authorized clients can connect + INET:localhost + LOCAL: + INET:merkur + INET:mars + -- snip -- + +- Q: Xprt refuses to start with the message "failed to set default font path + '...' Fatal server error: could not open default font 'fixed'". + What does that mean ? + A: This means one or more components in the font path (set via the option + "-fp") are either... + - ... not valid + - ... contain fonts not supported by this Xserver (e.g. support has not + be compiled "in" (usually happens for TrueType or F3 fonts (Sunsoft/F3 + fonts are Solaris-specific and _not_ supported by other vendors (AFAIK)) + when support for these fonts was not enabled at build time)) + - ... no font or font alias in the font path matches the name "fixed" + +- Q: Just copying my fonts into a directory and adding the path to my Xprt + command line didn't work - I always get "Fatal server error: could not + open default font 'fixed'". What am I doing wrong ? + A: Every Xserver needs an index file called "fonts.dir" to tell it which + fonts are available in this directory and which properties these fonts + have. + If you are lucky there may be already a "fonts.scale" file which can be + used by "mkfontdir" to create the "fonts.dir" file. + If there is no "fonts.scale" then you have to create your own + fonts.dir/fonts.scale either by hand or via a tool like "type1inst" (see + http://packages.debian.org/stable/utils/type1inst.html) for PS Type1 + fonts and "ttmkfdir" (see + http://packages.debian.org/stable/x11/ttmkfdir.html) for TrueType fonts. + +- Q: Xprt refuses to start with the message "Fatal server error: Cannot + establish any listening sockets - Make sure an X server isn't already + running". What does that mean ? + A: There is already a Xserver running at the display ID you have specified + to start Xprt (for example your framebuffer Xserver runs at ":0" then + Xprt can't run at the same display display). + +- Q: Xprt refuses to start with the message "Fatal server error: Failed to + establish all listening sockets". What does that mean ? + A: This means that the Xserver could not open one of it's sockets. Check + the permission of /tmp/.X11-pipe and /tmp/.X11-unix (on Solaris a + Xserver must run set-gid "root" to access these directories). + Either fix the permission or start Xprt with the option "-pn". Using this + option requires to access the server _always_ with + <hostname>:<displaynum> (see Xserver(1) manual page for the side-effects + of this option). + +- Q: Xprt refuses to start with the message "Fatal server error: could not + open default font 'fixed'" or "Fatal server error: could not open default + cursor font 'cursor'". + A: All Xservers at least two fonts as the minimum: One fixed-width font + ("fixed") and one font for the cursor ("cursor"). Be sure that the font + path contains these fonts. + I created a tarball which contains only these two fonts, get it from + http://puck.informatik.med.uni-giessen.de/people/gisburn/work/xprint/fonts/Xp_dummyfonts.tar.gz + +- Q: Xprt refuses to start with the message "Fatal server error: no screens + found". What does that mean ? + A: This means that Xprt could not find any printers. Either there are no + printers installed, "lpstat"/"lpc" could not find any printers or the + configuration does not contain any manual printer configurations + (see Q/A item "Which program is used by default by Xprt to enumerate the + printers on my system" for further details...). + + Two solutions: + 1. Using "PSspooldir" model: + Xprt releases from http://xprint.mozdev.org/ provide the "PSspooldir" + model config for such cases. Just edit the "Xprinters" and add + this line: + -- snip -- + Printer spooldir_tmp_Xprintjobs + -- snip -- + this will add the pre-configured (see + ${XPCONFIGDIR}/C/print/attributes/printer) "spooldir_tmp_Xprintjobs" + printer which will send jobs to the directory "/tmp/Xprintjobs/" + instead to a printer queue. + (This feature was added in the xprint.mozdev.org release 007, see + http://xprint.mozdev.org/bugs/show_bug.cgi?id=2475 ("RFE: Need + model-config which spools print jobs in a predefined directory")) + + 2. Manual setup: + Step 1: Provide a simple "Xprinters" spec file which contains a dummy + queue. + Example: + # Create "Xprinters_onlydummy" file which turns autolookup of printers + # OFF (using "Augment_Printer_List %none%") and provides one dummy + # queue called "ps_myscript" instead (using "Printer ps_myscript") + % echo "Augment_Printer_List %none%" >Xprinters_onlydummy + % echo "Printer ps_myscript" >>Xprinters_onlydummy + Step 2: Edit ${XPCONFIGDIR}/C/print/attributes/printer and add these + two lines: + -- snip -- + ps_myscript.xp-model-identifier: PSdefault + ps_myscript.xp-spooler-command: /home/sanja/xprint_test/my_xprt_cat_script.sh + -- snip -- + This means that the printer "ps_myscript" now uses the "PSdefault" + printer model and it will feed the jobs to the script + "/home/sanja/xprint_test/my_xprt_cat_script.sh" (via stdin). + Note that the absolute path is required for "*xp-spooler-command". + Step 3: Start Xprt on display 18, passing the "Xprinters_onlydummy" + using the "-XpFile" option: + % Xprt -XpFile ./Xprinters_onlydummy -pn -ac -audit 4 :18 + +- Q: "Printing itself works but the printout covers only 1/4 of the paper + - what am I doing wrong ?" + A: This is usually an indicator for a wrong DPI setting. The default + "PSdefault" model config uses 300 DPI but some printers only support + 600 DPI. + - Workaround: + Edit ${XPCONFIGDIR}/C/print/attributes/document and replace the line + "*default-printer-resolution: 300" with + "*default-printer-resolution: 600" + (Note that locale-specific settings in + ${XPCONFIGDIR}/${LANG}/print/attributes/document always override values + set in ${XPCONFIGDIR}/C/print/attributes/document.) + - Solution: + Create a model-config for your printer which only contains attributes + supported by your printer ("printer-resolutions-supported" is the + attribute in the "model-config" which holds the space-seperated list + of DPI values which are supported by the printer). + +- Q: "Printing works but I get large borders/margins..." / "[Top] margin is too small" / + "Margins are wrong" / etc. + A: Two possible causes: + - Usually same issue as "Printing itself works but the printout covers + only 1/4 of the page"-issue: Wrong DPI. + Solution: Check the DPI value and adjust it as described in the FAQ item + above. Common DPI values for the PostScript DDX are 240, 300, 360, 400 + and 600 DPI. + - You are trying to print "US-letter" on a "DIN-A4" paper or "DIN-A4" on + "US-letter". + Solution: Check your paper settings + Note that the default papersize for Xprt depends on the locale + (e.g. on the env var ${LANG}) Xprt is running in - "en_US"&co. get + US-letter, all others use DIN-A4 (incl. german/austrian etc. locales)). + Exception from this rule: If the selected printer does not support the + default paper size it will set no default paper size for this printer + (then the application side has to make an explicit choice). + +- Q: Xprt prints a warning like "Xp Extension: could not find config dir + /usr/X11R6/lib/X11/C/print" - what does that mean ? + A: This is actually the worst case what can happen. + The message indicates that Xprt was unable to find it's configuration + data. + Solution: + - Install configuration data at the requested location + OR + - Set the ${XPCONFIGDIR} env var to the location of the Xprt + configuration directory. + +- Q: Xprt crashes with "Fatal server error: Beziers this big not yet supported" + What does that mean ? + A: This is a known issue in the X11R6.5.1 code.

What does that mean ? + A: The policy file for the SECURITY extension cannot be found. + This is not serious unless you want to make use of features of the + SECURITY extensions (like treating clients as "untrusted", e.g. restrict + their access to certain Xserver resources). + Normally the missing policy file is a problem with your Unix/Linux X11 + distribution; consult your vendor where to get the missing file from. + Alternatively you can get the plain X11R6.6 security policy file from + ftp://ftp.x.org/pub/R6.6/xc/programs/Xserver/Xext/SecurityPolicy (copy it + to the matching location - but be sure that you do not overwrite any + existing security policy file). + +- Q: I have modified the "HPLJ4family" [or "HPDJ1600C" etc.] printer model to + work with my PostScript printer, but when I print I get empty places + where some text should be - what am I doing wrong here ? + A: The "HPLJ4family" and "HPDJ1600C" models are PCL-only, check + the model-config spec + (${XPCONFIGDIR}/C/print/models/${MODEL_NAME}/model-config) - if the + "xp-ddx-identifier" attribute says something with "PCL" (like + "XP-PCL-MONO" etc.) in the value string then this model-config is for + the PCL-DDX _only_ (e.g. their PMF fonts do not supply the neccesary + information (e.g. the "_ADOBE_POSTSCRIPT_FONTNAME" chunk is missing; + they only provide the "PCL_FONT_NAME" chunk) nor are these fonts + accessible via the PostScript-support in these printers. + A solution is to use the "PSdefault" model instead (and/or create your + customized own version of this model) - or look if there is a + model-config beginning with the same name and ending with "PS" (e.g. + "HPLJ4family-PS"). + +- Q: Xprt outputs warning messages like: + -- snip -- + Xp Extension: Can't load driver XP-PCL-MONO + init function missing + Xp Extension: Can't load driver XP-RASTER + init function missing + -- snip -- + What does that mean ? + A: Two possible problems: + 1. The requested driver is not supported by that version of Xprt. + For example Solaris 2.7 Xprt does not support XP-PCL-MONO nor the + XP-RASTER driver. + Valid values for the "xp-ddx-identifier" attribute in + ${XPCONFIGDIR}/*/print/attributes/printers and/or + ${XPCONFIGDIR}/*/print/models/*/model-config are + - Solaris 2.7: XP-POSTSCRIPT and XP-PCL-COLOR + - Solaris >=2.8: XP-POSTSCRIPT, XP-PCL-COLOR, XP-PCL-MONO and XP-RASTER + - HP-UX: XP-POSTSCRIPT, XP-PCL-COLOR, XP-PCL-MONO, XP-PCL-LJ3, + XP-PCL-DJ1200 and XP-RASTER + - xprint.mozdev.org release 007: XP-POSTSCRIPT and XP-RASTER + - xprint.mozdev.org release 008: XP-POSTSCRIPT, XP-PCL-COLOR, + XP-PCL-MONO, XP-PCL-LJ3 and XP-RASTER + - xprint.mozdev.org release >=1.0 (planned): XP-POSTSCRIPT, XP-PCL-COLOR, + XP-PCL-MONO, XP-PCL-LJ3, XP-RASTER and XP-PDF + 2. There may be too many drivers loaded into one Xprt instance. + By default a single Xserver instance can only handle three screens - and + since one Xprint DDX maps to one Xserver screen this limit applies to + the number of loaded Xprt drivers, too. + Starting with xprint.mozdev.org release 008 the per-Xserver screen limit + was increased from "3" to "8" to avoid this issue... + Workaround: Start a 2nd instance of Xprt which handles the other + drivers which do not fit into the first instance. + +- Q: Printing on Solaris with Mozilla/Eclipse [or any other Xprint client] + removes spaces between words. What is going wrong ? + A: This is a bug in the Solaris Xprint server binary (/usr/openwin/bin/Xprt). + Various bug reports have been filed, see + - http://xprint.mozdev.org/bugs/show_bug.cgi?id=3353 ("Solaris Xprt looses + space when rendering with '-monotype-arial-*'-fonts") + - http://bugzilla.mozilla.org/show_bug.cgi?id=199957 ("Solaris 8 Mozilla + removes spaces for text within <font face="Arial">...</font>") + Known workarounds: + - Remove the '-monotype-arial-*' fonts from the font path + - Use an alternate Xprint server like available in the "GISWxprint" package + (this package is identical to the "GISWxprintglue" package except that it + uses a Xprint server build from xprint.mozdev.org sources and not the + /usr/openwin/bin/Xprt binary from Solaris) + - Mozilla-only: Adding + -- snip -- + user_pref("print.xprint.font.rejectfontpattern", + "fname=-dt-.*;scalable=.*;outline_scaled=false;xdisplay=.*;xdpy=.*;ydpy=.*;xdevice=.*|" + + "fname=-monotype-arial.*;scalable=.*;outline_scaled=.*;xdisplay=.*;xdpy=.*;ydpy=.*;xdevice=.*"); + -- snip -- + to prefs.js works around the problem (see + http://bugzilla.mozilla.org/show_bug.cgi?id=199957#c6 , too). + +5. SOFTWARE DEVELOPMENT +- Q: How can I get the printable area (e.g. the portion of the page on which + the printer is physically capable of placing ink) of the paper after I + have chosen a paper ? + A: XpGetPageDimensions() returns the printable area and other information + about the page geometry. + +- Q: Do "offscreen" pixmaps work on Xprt ? + A: Yes, "offscreen" pixmaps are working on Xprt. + +- Q: How can I get the DPI value for the current Xprt server ? Can I use the + values from "xdpyinfo" ? + A: The Xprt screen resolution defines only the maximum resolution configured + for the matching DDX, the printers real DPI is obtained via an another + API (XprintUtil has a bunch of functions to get/set the document/page + resolution, see XpuGetResolutionList(), XpuFreeResolutionList(), + XpuGetResolution(), XpuSetPageResolution(), XpuSetDocResolution() and + XpuFindResolution()). + +- Q: Does Xprint/Xprt support font rotation ? + A: Yes - Xprint/Xprt supports font rotation at any angle via the matrix XLFD + enhancement (this even works for printer-builtin fonts !!). For details + see the paper "New Font Technology for X11R6" by Nathan Meyers <XXX: URL ?>. + Short: + The transformation-matrix for rotation can be calculated like this: + +-- --+ + | cos(angle) sin(angle)| + | | + |-sin(angle) cos(angle)| + +-- --+ + Examples: + 1. the following code fragment obtains a 180 degree rotated font (matrix [-1 0 0 -1]): + -- snip -- + ... = XLoadQueryFont(..., "-adobe-courier-bold-r-normal--*-[~24 0 0 ~24]-0-0-m-*-iso8859-1"); + -- snip -- + 2. the following code fragment obtains a 90 degree rotated font (matrix [0 1 -1 0]): + -- snip -- + ... = XLoadQueryFont(..., "-adobe-courier-bold-r-normal--*-[0 24 ~24 0]-0-0-m-*-iso8859-1"); + -- snip -- + +- Q: When I render something on my window and call XpStartPage() all the + rendered stuff is gone, I only get a white, empty paper. + What is going wrong here ? + A: Remember the rule that "only those drawings are printed on the paper which + were rendered between XpStartPage() and XpEndPage()". + XpStartPage() clears the window you passed as argument, e.g. it creates + a new, blank sheet of paper where you can do your rendering stuff on. + XpEndpage() then pushes the "paper sheet" to the stash of papers from the + document in process. + Solution - if you want to render something once for multiple or all pages: + Render on a offscreen pixmap and copy (with XCopyArea()) the content to + the "paper" drawable (after calling XpStartPage()) - XpStartpage() only + affects the window passed as parameter. + +- Q: What is XpStartDoc() for ? + A: ISO 10175 and some advanced printing systems by IBM and HP had set forth + the standard that a "Job" is made up of one or more "Documents", and + each document is made up of one or more "Pages". Xprint was designed that + in a true ISO 10175 environment/implementation (lp(1) on steroids, and + with an API), Xprt can actually learn about all printers and their + capabilities though API's into the printer subsystem (vs. using config + files), map Job/Doc/Page directly into ISO 10175 equivalents, and use + APIs to view job status and kill jobs (vs. cancel(1), lpcancel(1), + lpstatus(1)). + Because most applications of the day are only printing one document per + job, XpStartPage() was designed that it generates a "synthetic" + XpStartDoc() if it has not been called yet. + +- Q: How does the XLFD for printer-builtin fonts look like ? + A: XXX + +- Q: How can I scale images using the Xprint API ? + A: XXX + +- Q: How do I use the XprintUtil library ? + A: XXX + +- Q: Why does XGetImage() not work for Xprt ? + A: There are at least two reasons why XGetImage() does not work for Xprt: + 1. Most of the Xprt DDX implementations do not render itself on any + bitmaps like the framebuffer(=video) DDX do, they translate the + rendering commands into the matching commands of the printer language + (it is technically possible to implement such support for XGetImage() + even for those drivers - but there is reason [2]:) + 2. Xprt usually operates at high resolutions which results in very large + dimensions. If a client would request the 24bit TrueColor _bitmap_ + data for a _whole_ DIN-A4 page at 2400 DPI a data chunk of ~173 + megabytes would be the response. This would be more or less a + DOS(=Denial of Service) for either the client, the network and/or the + server. + +- Q: How to print with Xt/Athena widgets ? + A: XXX + +- Q: How to print with Xt/Motif widgets ? + A: XXX + +- Q: What are the differences between normal display and Xprint display ? + A: XXX + +- Q: How can I find/identify printer-builtin fonts ? + A: XXX + +- Q: How do I scale images ? + A: XXX + +- Q: libXp Image scaling vs. max. request size ? + A: XXX + +- Q: How can I use XprintUtils ? + A: XXX + +- Q: How do I calculate the DPI values for Xprt DDX screens ? + A: XXX + +- Q: How do I find scaleable fonts ? + A: XXX + +- Q.

KNOWN BUGS: + ('P'=Problem, 'S'=Solution) + - P: Xprt build from Xfree86 sources is completely broken and unuseable. + S: Build Xprt from the CVS tree at http://xprint.mozdev.org/ or the + X.org X11R6.5.1 sources (note that the client side Xprint extension + library ("libXp.so") from Xfree86 is not broken and do not need to be + replaced). + + - P: The code which matches XLFD names to PS Type1 font names is + case-sensitive in Xprts build from X.org X11R6.5.1/X11R6.6 and the + current Solaris Xprt.
