Peter Deutsch, Aladdin Enterprises. * Modified by rjl 1995-03-29 to use BMP printer code * Modified by Pierre Arnaud 1999-02-18 (see description below) * Modified by lpd 1999-04-03 for compatibility with Borland C++ 4.5. * Modified by Pierre Arnaud 1999-10-03 (accept b&w printing on color printers). * Modified by Pierre Arnaud 1999-11-20 (accept lower resolution) * Bug fixed by Pierre Arnaud 2000-03-09 (win_pr2_put_params error when is_open) * Bug fixed by Pierre Arnaud 2000-03-20 (win_pr2_set_bpp did not set anti_alias) * Bug fixed by Pierre Arnaud 2000-03-22 (win_pr2_set_bpp depth was wrong) * Modified by Pierre Arnaud 2000-12-12 (mainly added support for Tumble) * Bug fixed by Pierre Arnaud 2000-12-18 (-dQueryUser now works from cmd line) */ /* This driver uses the printer default size and resolution and * ignores page size and resolution set using -gWIDTHxHEIGHT and * -rXxY. You must still set the correct PageSize to get the * correct clipping path. * The code in win_pr2_getdc() does try to set the printer page * size from the PostScript PageSize, but it isn't working * reliably at the moment. * * This driver doesn't work with some Windows printer drivers. * The reason is unknown. All printers to which I have access * work. * * rjl 1997-11-20 */ /* Additions by Pierre Arnaud (Pierre.Arnaud@opac.ch) * * The driver has been extended in order to provide some run-time * feed-back about the default Windows printer and to give the user * the opportunity to select the printer's properties before the * device gets opened (and any spooling starts). * * The driver returns an additional property named "UserSettings". * This is a dictionary which contens are valid only after setting * the QueryUser property (see below). The UserSettings dict contains * the following keys: * * DocumentRange [begin end] (int array, can be set) * Defines the range of pages in the document; [1 10] would * describe a document starting at page 1 and ending at page 10. * * SelectedRange [begin end] (int array, can be set) * Defines the pages the user wants to print. * * MediaSize [width height] (float array, read only) * Current printer's media size. * * Copies n (integer, can be set) * User selected number of copies. * * PrintCopies n (integer, read only) * Number of copies which must be printed by Ghostscript itself. * This is still experimental. * * DocumentName name (string, can be set) * Name to be associated with the print job. * * UserChangedSettings (bool, read only) * Set to 'true' if the last QueryUser operation succeeded. * * Paper n (integer, can be set) * Windows paper selection (0 = automatic). * * Orient n (integer, can be set) * Windows paper orientation (0 = automatic). * * Color n (integer, can be set) * Windows color (0 = automatic, 1 = monochrome, 2 = color). * * MaxResolution n (integer, can be set) * Maximum resolution in pixels pet inch (0 = no maximum). If * the printer has a higher resolution than the maximum, trim * the used resolution to the best one (dpi_chosen <= dpi_max, * with dpi_chosen = dpi_printer / ratio). */ /* Supported printer parameters are : * * -dBitsPerPixel=n * Override what the Window printer driver returns. * * -dNoCancel * Don't display cancel dialog box. Useful for unattended or * console EXE operation. * * -dQueryUser=n * Query user interactively for the destination printer, before * the device gets opened. This fills in the UserSettings dict * and the OutputFile name properties. The following values are * supported for n: * 1 => show standard Print dialog * 2 => show Print Setup dialog instead * 3 => select default printer * other, does nothing * * The /Duplex & /Tumble keys of the setpagedevice dict are supported * if the Windows printer supports duplex printing. */ #include "gdevprn.h" #include "gdevpccm.h" #include "windows_.h" #include #include "gp_mswin.h" #include "gp.h" #include "gpcheck.h" #include "commdlg.h" /* Make sure we cast to the correct structure type. */ typedef struct gx_device_win_pr2_s gx_device_win_pr2; #undef wdev #define wdev ((gx_device_win_pr2 *)dev) /* Device procedures */ /* See gxdevice.h for the definitions of the procedures. */ static dev_proc_open_device(win_pr2_open); static dev_proc_close_device(win_pr2_close); static dev_proc_print_page(win_pr2_print_page); static dev_proc_map_rgb_color(win_pr2_map_rgb_color); static dev_proc_map_color_rgb(win_pr2_map_color_rgb); static dev_proc_get_params(win_pr2_get_params); static dev_proc_put_params(win_pr2_put_params); static void win_pr2_set_bpp(gx_device * dev, int depth); static const gx_device_procs win_pr2_procs = prn_color_params_procs(win_pr2_open, gdev_prn_output_page, win_pr2_close, win_pr2_map_rgb_color, win_pr2_map_color_rgb, win_pr2_get_params, win_pr2_put_params); #define PARENT_WINDOW HWND_DESKTOP BOOL CALLBACK CancelDlgProc(HWND, UINT, WPARAM, LPARAM); BOOL CALLBACK AbortProc2(HDC, int); /* The device descriptor */ typedef struct gx_device_win_pr2_s gx_device_win_pr2; struct gx_device_win_pr2_s { gx_device_common; gx_prn_device_common; HDC hdcprn; bool nocancel; int doc_page_begin; /* first page number in document */ int doc_page_end; /* last page number in document */ int user_page_begin; /* user's choice: first page to print */ int user_page_end; /* user's choice: last page to print */ int user_copies; /* user's choice: number of copies */ int print_copies; /* number of times GS should print each page */ float user_media_size[2]; /* width/height of media selected by user */ char doc_name[200]; /* name of document for the spooler */ char paper_name[64]; /* name of selected paper format */ bool user_changed_settings; /* true if user validated dialog */ int user_paper; /* user's choice: paper format */ int user_orient; /* user's choice: paper orientation */ int user_color; /* user's choice: color format */ int max_dpi; /* maximum resolution in DPI */ int ratio; /* stretch ratio when printing */ int selected_bpp; /* selected bpp, memorised by win_pr2_set_bpp */ bool tumble; /* tumble setting (with duplex) */ int query_user; /* query user (-dQueryUser) */ HANDLE win32_hdevmode; /* handle to device mode information */ HANDLE win32_hdevnames; /* handle to device names information */ DLGPROC lpfnAbortProc; DLGPROC lpfnCancelProc; HWND hDlgModeless; bool use_old_spool_name; /* user prefers old \\spool\ name */ gx_device_win_pr2* original_device; /* used to detect copies */ }; gx_device_win_pr2 far_data gs_mswinpr2_device = { prn_device_std_body(gx_device_win_pr2, win_pr2_procs, "mswinpr2", DEFAULT_WIDTH_10THS, DEFAULT_HEIGHT_10THS, 72.0, 72.0, 0, 0, 0, 0, 0, win_pr2_print_page), /* depth = 0 */ 0, /* hdcprn */ 0, /* nocancel */ 0, /* doc_page_begin */ 0, /* doc_page_end */ 0, /* user_page_begin */ 0, /* user_page_end */ 1, /* user_copies */ 1, /* print_copies */ { 0.0, 0.0 }, /* user_media_size */ { 0 }, /* doc_name */ { 0 }, /* paper_name */ 0, /* user_changed_settings */ 0, /* user_paper */ 0, /* user_orient */ 0, /* user_color */ 0, /* max_dpi */ 0, /* ratio */ 0, /* selected_bpp */ false, /* tumble */ -1, /* query_user */ NULL, /* win32_hdevmode */ NULL, /* win32_hdevnames */ NULL, /* lpfnAbortProc */ NULL, /* lpfnCancelProc */ NULL, /* hDlgModeless */ false, /* use_old_spool_name */ NULL /* original_device */ }; /********************************************************************************/ static int win_pr2_getdc(gx_device_win_pr2 * dev); static int win_pr2_update_dev(gx_device_win_pr2 * dev, LPDEVMODE pdevmode); static int win_pr2_update_win(gx_device_win_pr2 * dev, LPDEVMODE pdevmode); static int win_pr2_print_setup_interaction(gx_device_win_pr2 * dev, int mode); static int win_pr2_write_user_settings(gx_device_win_pr2 * dev, gs_param_list * plist); static int win_pr2_read_user_settings(gx_device_win_pr2 * dev, gs_param_list * plist); static void win_pr2_copy_check(gx_device_win_pr2 * dev); /********************************************************************************/ /* Open the win_pr2 driver */ static int win_pr2_open(gx_device * dev) { int code; int depth; PRINTDLG pd; POINT offset; POINT size; float m[4]; FILE *pfile; DOCINFO docinfo; float ratio = 1.0; win_pr2_copy_check(wdev); /* get a HDC for the printer */ if ((wdev->win32_hdevmode) && (wdev->win32_hdevnames)) { /* The user has already had the opportunity to choose the output */ /* file interactively.
