-Version 3.3 (released 2001-08-19)
-=================================
-* Options
- - There is a new option "-sPJLJob" for declaring the generated file as a
- PJL print job.
- - I've documented the options "PCLInit1" and "PCLInit2" because I now know of
- a situation where one of them is needed.
- - The option "-dCUPSMessages" has been split into "-dCUPSMessages" and
- "-dCUPSAccounting".
- - I have added a new option "-dConfigureEveryPage" which is needed by some
- not strictly PCL-3-conforming printers.
-* Compilation
- - Adaptation to AFPL ghostscript 7.0 (previously only available as a patch
- file) and GNU ghostscript 6.51.
-* Other
- - I've removed the "PageCountFile" configuration parameter for cups-pcl3
- because the corresponding device parameter can also be set from PostScript.
- - I've corrected a bug which showed itself in wrong colour rendering for
- yellow on 64-bit platforms when using Floyd-Steinberg error diffusion.
- - If you've been using gs-pcl3-hpdj8xxc.ppd or gs-pcl3-hpdj1120c.ppd in an
- environment where you had to explicitly specify values for the options
- "*eprnBlackLevels" or "*eprnNonBlackLevels" you'll have to replace these
- now with a reference to "*pcl3IntensityLevels".
-
-
-
-Version 3.2 (released 2001-03-26)
-=================================
-This is the first non-beta release of pcl3 after hpdj 2.6.
-
-The main functional extension in this release is support for the Common UNIX
-Printing System (CUPS):
-- I have added PPD files for the supported subdevices.
-- The package now contains a filter for using pcl3 with CUPS.
-- The driver has a new option "-dCUPSMessages" to generate messages in the
- format demanded by CUPS.
-
-
-Version 3.1 (released 2001-02-28)
-=================================
-- After waiting almost 5 years for someone to implement it where it logically
- belongs (in the ghostscript core distribution somewhere near the "prn"
- device), I have finally dropped a deliberate restriction in hpdj/pcl3 and
- have implemented Floyd-Steinberg error diffusion on my own. The resulting
- quality is quite good, the performance isn't. There is a new option
- "-sIntensityRendering" which selects the rendering method to use.
-- I have added support for the RGB colour model. This is mostly of interest to
- people writing other ghostscript drivers and wishing to use pcl3's "eprn"
- device.
-- I have changed the "SendNULs" option to be of integer type instead of a
- boolean.
-- The option "-dNoHalftoning" has been replaced by the value "printer" for the
- new option "-sIntensityRendering".
-- I have changed the %N name used by the message catalogues for pcl3opts from
- "pcltools" to "pcl3opts". You should delete your old catalogues if you
- installed them.
-
-
-Version 3.0.2 (released 2000-11-09)
-===================================
-- Because I'm disappointed with the way the FTP server previously used for
- distributing hpdj is administered, I've moved pcl3's WWW home page to
- http://home.t-online.de/home/Martin.Lottermoser/pcl3.html.
-- I've made one change in the generated PCL code (argument value for Start
- Raster Graphics) which, according to the HP documentation available to me,
- should be equivalent but which is apparently a necessary condition for duplex
- printing on the HP DJ 970C.
-- The option -dOnlyCRD is now documented.
-- Rearrangements in the output of pcl3opts, addition of -dOnlyCRD if needed.
-- Clarifications in the reference page.
-
-
-Version 3.0.1 (released 2000-10-27)
-===================================
-Bugfix release (-sSubdevice leading to 300 ppi resolution).
-
-
-Version 3.0 (released 2000-10-22)
-=================================
-As predicted in hpdj 2.5, the name of this driver has been changed to "pcl3".
-I am sorry it took so long for this version to be released, but, apart from
-other tasks intervening, the work for this driver expanded in a manner I had
-not anticipated. The current version is practically a new implementation, hence
-this is only a beta release which should be approached with appropriate care.
-
-* Functionality/behaviour of the driver
-
- + Removed Functionality
- - I have removed the optional source code for generating a device-specific
- 'InputAttributes' page device parameter. I had misunderstood the purpose
- of this parameter in PostScript.
-
- + Modifications
- - The option "Colo[u]rMode" is now called ""Colo[u]rModel" and its default
- value is called "Gray" instead of "mono".
- - The default for "ManualFeed" is now always "false".
- - The "MarginFile" option has been renamed "MediaConfigurationFile" and
- media configuration files now expect PPD mediaOption keywords (like "A4")
- instead of PCL page size codes ("26" for ISO A4) to identify media sizes.
- - The "MediaType" parameter has been renamed "Medium" to prevent a conflict
- with PostScript Level 3. There are extensions in the permissible values
- as well.
- - The "Model" option has been renamed "Subdevice" and the permissible
- values have been changed.
- - The "PagecountFile" option is now called "PageCountFile" in order to
- agree with the spelling of the page device parameter "PageCount".
- - The default compression method depends now on the subdevice chosen.
- For "unspec", it is 2 instead of 9 as previously.
-
- + Extensions
- - More printer models are explicitly supported (in particular some of the
- series 300 and 600 DeskJets).
- - It is now possible to select supported printer models (subdevices)
- directly by a "-sDEVICE" option.
- - The driver can now also deal with media fed long edge first. This is
- needed for envelope sizes on some older DeskJets. The implementation is
- actually more general and adds support for the standard
- PostScript-Level-3 page device parameter "LeadingEdge".
- - The driver now reacts to media positions (numbers identifying input or
- output trays) determined by PostScript's media selection process.
- - The driver now supports banner printing.
- - The driver now supports duplex printing.
- - There is a new option "-dNoHalftoning" which turns off ghostscript's
- halftoning.
- - I've added support for printers (e.g., Olivetti JP 792) which violate PCL
- in requiring the black pixel plane to be sent last when printing in
- colour.
- - You now have direct access to print quality parameters for older DeskJets.
- - There are two new options with minor usefulness (SendNULs, PJLLanguage).
-
-* Documentation
- - I have rewritten the documentation in SGML, using the DocBook DTD.
- The distribution contains derived variants as an nroff/troff manual page
- and in HTML format.
- - To my dismay I have discovered that the description on how to increase the
- halftone screen frequency does not work with current ghostscript versions.
- The manual page has been corrected accordingly.
- - The support for functionality needing the PCL command "Configure Raster
- Data" is no longer marked as unsafe because I have finally obtained some
- official HP documentation on it.
- - I've added a preliminary version of a TeX document (notes.tex) containing
- useful information for other driver implementors.
-
-* Other Changes
- - I've added a command "pcl3opts" which parses PCL-3+ files and guesses the
- options needed to generate a file with similar settings using pcl3. This
- command is intended for people having access to a manufacturer-endorsed
- driver for their printer.
- - I've added some PostScript files to the package:
- - calign.ps for checking the relative alignment of ink cartridges
- - dumpppd.ps for dumping the contents of the page device dictionary to
- standard output
- - levels-test.ps for checking the basic colour capabilities of ghostscript
- and the driver
-
-* Compilation/Sources
- - I have restructured the driver and split it into three layers.
- The top-most one is a new abstract gs device ("eprn") extending
- ghostscript's standard "prn" device and dealing with aspects independent of
- PCL. The lowest layer is a PCL-3+ generator. Both components are intended
- to be usable in other contexts as well. The "pcl3" driver proper is the
- intermediate layer connecting the other two.
- - The way you have to integrate pcl3's sources in the compilation has
- changed. You now have less compilation options to worry about.
-
-
-
-Version 2.6 (released 1999-10-16)
-=================================
-The main purpose of this version is to update the address of hpdj's FTP site
-and my e-mail address which have changed. Other changes are:
-
-* Documentation
- - I have removed the description of HPDJ_INPUTATTRIBUTES from README.hpdj.
- The symbol can still be defined during compilation if you need it, but
- because I had misunderstood the purpose of the 'InputAttributes' page
- device parameter hpdj's resulting behaviour is not in agreement with the
- PostScript language definition.
- - README.hpdj now describes a fix for ghostscript's BG/UCR bug which was
- previously mentioned only on hpdj's WWW home page.
- - I've made numerous small changes in the manual page and README.hpdj.
-
-* Compilation
- - The make file parts needed for hpdj are no longer diffs but simply text
- segments which can be inserted with an ordinary text editor.
-
-There are almost no changes in the source code.
-
-
-
-Version 2.5 (released 1998-11-22)
-=================================
-This is mainly a release to adapt hpdj to gs 5.50. There are no changes in
-functionality.
-
-Unless there arise reasons for quickly issuing a new package, this will be the
-last release where the driver is called "hpdj". The new name will probably be
-"pcl3" and numbering will start with version 3.0.
-
-* Changes in behaviour
- - hpdj will now complain if you specify the option 'BitsPerPixel' unless the
- value given happens to be the same as the one chosen by hpdj.
-
-* Compilation
- - hpdj should now adapt automatically to the ghostscript version used, i.e.,
- you no longer have to set version-specific defines for older gs releases.
- - One user encountered and located a bug in Microsoft VC++ 5.0 which
- prevented reading margin files. This release works around the bug.
-
-* Documentation
- - Numerous small changes.
-
-
-
-Version 2.4 (released 1998-04-27)
-=================================
-Starting with this version, hpdj is released under the terms of the GNU Library
-General Public License (LGPL) instead of the GNU GPL.
-
-* Extensions
- - This version supports the Color Resolution Enhancement technology (C-REt)
- feature of some HP series-800 DeskJets, at least as far as I've been able
- to discover how this works without any documentation from HP. See the
- description of the new options 'BlackLevels' and 'CMYLevels' in the manual
- page.
- - There is a new option, "PagecountFile", which can be used to keep track of
- the number of pages printed. It is intended for spooler backends.
- - As an example of an input filter for a BSD spooler (lpr), I've added a file
- 'if-hpdj' to the distribution. Read the comments in the file to find out
- what it can do.
- - I've extended the list of PCL media size codes known to hpdj by some codes
- of interest to people with series-1100 DeskJets.
-
-* Modifications
- - The DJ 850C/855C/unspec margin information has been modified:
- - The margins for the JIS B5 format were demonstrably wrong for the DJ 850C
- and have been changed.
- - I've removed the entry for US A2 envelopes because contrary to what I
- believed previously this size is not supported.
-
-* Documentation
- - The FILES section in the manual page has been restructured and extended as
- a CONFIGURATION section. In particular, for those not familiar with
- PostScript, I've added much more on configuration with PostScript commands.
-
-* Compilation
- - I have added a missing "#include <errno.h>" directive to hpdjprn.c.
- - I have added an include directive for Aladdin's header "std.h" where
- appropriate in order to avoid some name clashes with non-standard system
- types like 'uint' on some operating systems (e.g., FreeBSD).
-
-
-
-
-Version 2.3 (released 1997-12-16)
-=================================
-This is a release to fix a bug preventing linking when HPDJ_MARGIN_FILE was
-defined during compilation.
-
-
-
-Version 2.2 (released 1997-12-08)
-=================================
-Most of the changes in this version are either in the documentation or internal.
-So far, only one bug has been reported for hpdj 2.1 and it is concerned with
-compilation and not with the generated PCL code (see below).
-
-* Changes in behaviour
-
- - Printing with a series-500 DeskJet on envelope sizes now assumes manual
- feed unless overridden by the new 'ManualFeed' option.
-
- - I have finally managed to see how to support automatic rotation for pages
- in landscape orientation without help from 'setpagedevice'. The rule is
- now: put media into the input tray short edge first and let hpdj worry
- about the rest.
-
- In particular, it is now possible to use setpagedevice to declare landscape
- orientation in default user space and thus obtain a file which can be
- viewed on the screen in its proper orientation and which will, without
- modifications, print correctly if processed by hpdj.
-
- - hpdj can now also install its own 'InputAttributes' dictionary in its page
- device dictionary. (And if you don't know what that can be used for you
- should skip this paragraph.) There will be one entry for each page size
- supported by the printer model chosen. This has the disadvantage that
- unsupported page sizes no longer produce readable messages like
-
- ? Device hpdj: This document requests a page size of 210 x 297 pt.
- This exceeds the custom page size limits for the DeskJet 850C.
-
- from hpdj but instead slightly cryptic messages like
-
- Error: /configurationerror in --setpagedevice--
- Additional information: [/PageSize [210 297]]
-
- from the setpagedevice operator (some ghostscript versions, e.g. gs 4.03,
- even omit the second of these lines). The advantage is that setpagedevice
- can now perform the usual media size matching.
-
- This feature is not active by default because it generates the wrong
- initial CTM if the printer model supports custom page sizes and the media
- size requested could be matched as a custom page size. This is due to a bug
- in make_adjustment_matrix() (file zmedia2.c) which is present in at least
- gs 3.53, gs 4.03 and gs 5.10. The hpdj distribution contains a patch file
- for zmedia2.c based on gs 5.10 which fixes this problem.
-
- Compile hpdj with -DHPDJ_INPUTATTRIBUTES to activate this feature.
-
-
-* Command line options:
-
- - New options (see the manual page for descriptions):
- - DryTime
- - ManualFeed
-
- - Changes in option interfaces (no change in functionality):
- - ColourMode and ColorMode accept "monochrome" as a synonym for "mono".
- - MediaType now recognizes the string "photo paper".
- - PrintQuality accepts "best" as a synonym for "presentation".
-
-
-* Manual page:
- - I have made the nroff/troff syntax more acceptable to man commands of
- limited intelligence and faulty man macros. In particular, man is now more
- likely to discover that preprocessing by tbl is needed, and nroff should
- no longer get confused what the "previous" font is after CW has been used.
- (The Linux system on which I developed hpdj 2.1 did not have these faults,
- but since then I have switched distributions...)
- - The man page now contains a reference to hpdj's FTP site.
- - The list of printers known to work with hpdj has been extended.
- - I have rewritten most of the "LIMITATIONS" section.
-
-* Additional files in the distribution:
- - This file :-).
- - A copy of the hpdj home page, hpdj.html, giving a short introduction to
- ghostscript and hpdj, together with instructions on where to get them.
- - Patch files for devs.mak in Aladdin ghostscript 3.53 and 5.10.
- - Patch file for zmedia2.c (bug in make_adjustment_matrix()) based on Aladdin
- ghostscript 5.10.
- - Margin test files in landscape orientation for ISO A4 and US Letter.
-
-* Compilation:
- - In two places, I had used dynamic initializers for structs. This is not
- required to be supported by ISO/ANSI C and gave error messages from at
- least one compiler. This bug has been fixed.
- - A user reported problems with the interpretation of return values of
- fprintf() on his non-ISO/ANSI-C-conforming system. This lead to hpdj
- erroneously assuming that an error had occurred. The code has been changed
- to circumvent this problem.
- - Based on user feedback, I have rewritten parts of README.hpdj.
- - There is a new printer model, "none", intended only as a compile-time value
- for HPDJ_DEFAULT_MODEL. Using this model leads to an error message telling
- the user that s/he should explicitly specify -sModel. I have introduced this
- value for the benefit of persons distributing binary versions of ghostscript
- and wishing to force their users to deliberately choose the printer model.
- This is the default value for HPDJ_DEFAULT_MODEL now.
- - The source code for the driver is now distributed over 7 files instead of
- 3 as before.
-
-
-
-Version 2.1 (released 1997-06-08)
-=================================
-This was the first widely-released version of hpdj.
