;;; Commentary:
;; ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;;
;; Introduction
;; ------------
;;
;; With `printing' you can preview or print a PostScript file. You can also
;; print a text file using PostScript, and preview or print buffers that use
;; certain special modes like mh-folder-mode, rmail-summary-mode,
;; gnus-summary-mode, etc. This package also includes a PostScript/text
;; printer database.
;;
;; There are two user interfaces:
;;
;; * Menu interface:
;; The `printing' menu replaces the usual print options in the menu bar.
;; This is the default user interface.
;;
;; * Buffer interface:
;; You can use a buffer interface instead of menus. It looks like a
;; customization buffer. Basically, it has the same options found in the
;; menu and some extra options, all this on a buffer.
;;
;; `printing' is prepared to run on GNU, Unix and NT systems.
;; On GNU or Unix system, `printing' depends on gs and gv utilities.
;; On NT system, `printing' depends on gstools (gswin32.exe and gsview32.exe).
;; To obtain ghostscript, ghostview and GSview see the URL
;; `https://www.gnu.org/software/ghostscript/ghostscript.html'.
;;
;; `printing' depends on ps-print package to generate PostScript files, to
;; spool and to despool PostScript buffer. So, `printing' provides an
;; interface to ps-print package and it also provides some extra stuff.
;;
;; `printing' was inspired by:
;;
;; print-nt.el Frederic Corne <frederic.corne@erli.fr>
;; Special printing functions for Windows NT
;;
;; mh-e-init.el Tom Vogels <tov@ece.cmu.edu>
;; PS-print for mail messages
;;
;; win32-ps-print.el Matthew O. Persico <mpersico@erols.com>
;; PostScript printing with ghostscript
;;
;; ps-print-interface.el Volker Franz <volker.franz@tuebingen.mpg.de>
;; Graphical front end for ps-print and previewing
;;
;;
;; Log Messages
;; ------------
;;
;; The buffer *Printing Command Output* is where the `printing' log messages
;; are inserted. All program called by `printing' has a log entry in the
;; buffer *Printing Command Output*. A log entry has the following form:
;;
;; PROGRAM (ARG...)
;; MESSAGE
;; Exit status: CODE
;;
;; Where
;; PROGRAM is the program activated by `printing',
;; ARG is an argument passed to PROGRAM (it can have more than one argument),
;; MESSAGE is an error message returned by PROGRAM (it can have no message, if
;; PROGRAM is successful),
;; and CODE is a numeric exit status or a signal description string.
;;
;; For example, after previewing a PostScript file, *Printing Command Output*
;; will have the following entry:
;;
;; /usr/bin/gv ("/home/user/example/file.ps")
;; Exit status: 0
;;
;; In the example above, the previewing was successful. If during previewing,
;; you quit gv execution (by typing C-g during Emacs session), the log entry
;; would be:
;;
;; /usr/bin/gv ("/home/user/example/file.ps")
;; Exit status: Quit
;;
;; So, if something goes wrong, a good place to take a look is the buffer
;; *Printing Command Output*. Don't forget to see also the buffer *Messages*,
;; it can help.
;;
;;
;; Novices (First Users)
;; ---------------------
;;
;; First of all, see printing documentation only to get an idea of what
;; `printing' is capable.
;;
;; Then try to set the variables: `pr-ps-name', `pr-ps-printer-alist',
;; `pr-txt-name', `pr-txt-printer-alist' and `pr-path-alist'. These variables
;; are the main variables for printing processing.
;;
;; Now, please, see these variables documentation deeper. You can do this by
;; typing C-h v pr-ps-name RET (for example) if you already loaded printing
;; package, or by browsing printing.el source file.
;;
;; If the documentation isn't clear or if you find a way to improve the
;; documentation, please, send an email to maintainer. All printing users
;; will thank you.
;;
;; One way to set variables is by calling `pr-customize', customize all
;; variables and save the customization by future sessions (see Options
;; section). Other way is by adding code to your init file; see below
;; for a first setting template that it should be inserted on your
;; init file:
;;
;; * Example of setting for Windows system:
;;
;; (require 'printing) ; load printing package
;; (setq pr-path-alist
;; '((windows "c:/applications/executables" PATH ghostview mpage)
;; (ghostview "c:/gs/gsview-dir")
;; (mpage "c:/mpage-dir")
;; ))
;; (setq pr-txt-name 'prt_06a)
;; (setq pr-txt-printer-alist
;; '((prt_06a "print" nil "/D:\\\\printers\\prt_06a")
;; (prt_07c nil nil "/D:\\\\printers\\prt_07c")
;; (PRN "" nil "PRN")
;; (standard "redpr.exe" nil "")
;; ))
;; (setq pr-ps-name 'lps_06b)
;; (setq pr-ps-printer-alist
;; '((lps_06a "print" nil "/D:" "\\\\printers\\lps_06a")
;; (lps_06b "print" nil nil "\\\\printers\\lps_06b")
;; (lps_07c "print" nil "" "/D:\\\\printers\\lps_07c")
;; (lps_08c nil nil nil "\\\\printers\\lps_08c")
;; (LPT1 "" nil "" "LPT1:")
;; (PRN "" nil "" "PRN")
;; (standard "redpr.exe" nil "" "")
;; ))
;; (pr-update-menus t) ; update now printer and utility menus
;;
;; * Example of setting for GNU or Unix system:
;;
;; (require 'printing) ; load printing package
;; (setq pr-path-alist
;; '((unix "." "~/bin" ghostview mpage PATH)
;; (ghostview "$HOME/bin/gsview-dir")
;; (mpage "$HOME/bin/mpage-dir")
;; ))
;; (setq pr-txt-name 'prt_06a)
;; (setq pr-txt-printer-alist
;; '((prt_06a "lpr" nil "prt_06a")
;; (prt_07c nil nil "prt_07c")
;; ))
;; (setq pr-ps-name 'lps_06b)
;; (setq pr-ps-printer-alist
;; '((lps_06b "lpr" nil "-P" "lps_06b")
;; (lps_07c "lpr" nil nil "lps_07c")
;; (lps_08c nil nil nil "lps_08c")

;; (pr-update-menus t) ; update now printer and utility menus
;;
;;
;; NOTE 1: Don't forget to download and install ghostscript utilities (see
;; Utilities section).
;;
;; NOTE 2: The `printer-name' and `ps-printer-name' variables don't need to be
;; set, as they are implicit set by `pr-ps-printer-alist' and
;; `pr-txt-printer-alist'.
;;
;; NOTE 3: The duplex feature will only work on PostScript printers that
;; support this feature.
;; You can check if your PostScript printer supports duplex feature
;; by checking the printer manual. Or you can try these steps:
;; 1. Open a buffer (or use the *scratch* buffer).
;; 2. Type:
;; First line (on first page)
;; ^L
;; Second line (on second page)
;; 3. Print this buffer with duplex turned on.
;; If it's printed 2 (two) sheets of paper, then your PostScript
;; printer doesn't have duplex feature; otherwise, it's ok, your
;; printer does have duplex feature.
;;
;; NOTE 4: See Tips section.
;;
;;
;; Tips
;; ----
;;
;; 1. If you have a local printer, that is, a printer which is connected
;; directly to your computer, don't forget to connect the printer to your
;; computer before printing.
;;
;; 2. If you try to print a file and it seems that the file was printed, but
;; there is no paper in the printer, then try to set `pr-delete-temp-file'
;; to nil. Probably `printing' is deleting the temporary file before your
;; local system can get it to send to the printer.
;;
;; 3. Don't try to print a dynamic buffer, that is, a buffer which is
;; modifying while `printing' tries to print. Eventually you got an error
;; message. Instead, save the dynamic buffer to a file or copy it in
;; another buffer and, then, print the file or the new static buffer.
;; An example of dynamic buffer is the *Messages* buffer.
;;
;; 4. When running Emacs on Windows (with or without cygwin), check if your
;; printer is a text printer or not by typing in a DOS window:
;;
;; print /D:\\host\printer somefile.txt
;;
;; Where, `host' is the machine where the printer is directly connected,
;; `printer' is the printer name and `somefile.txt' is a text file.
;;
;; If the printer `\\host\printer' doesn't print the content of
;; `somefile.txt' or, instead, it returns the following message:
;;
;; PostScript Error Handler
;; Offending Command = CCC
;; Stack =
;;
;; Where `CCC' is whatever is at the beginning of the text to be printed.
;;
;; Therefore, the printer `\\host\printer' is not a text printer, but a
;; PostScript printer. So, please, don't include this printer in
;; `pr-txt-printer-alist' (which see).
;;
;; 5. You can use gsprint instead of ghostscript to print monochrome PostScript
;; files in Windows. The gsprint utility documentation says that it is more
;; efficient than ghostscript to print monochrome PostScript.
;;
;; To print non-monochrome PostScript file, the efficiency of ghostscript
;; is similar to gsprint.
;;
;; Also the gsprint utility comes together with gsview distribution.
;;
;; For more information about gsprint see
;; `https://www.cs.wisc.edu/~ghost/gsview/gsprint.htm'.
;;
;; As an example of gsprint declaration:
;;
;; (setq pr-ps-printer-alist
;; '((A "gsprint" ("-all" "-twoup") "-printer " "my-b/w-printer-name")
;; (B "gsprint" ("-all" "-twoup") nil "-printer my-b/w-printer-name")
;; ;; some other printer declaration
;; ))
;;
;; The example above declares that printer A prints all pages (-all) and two
;; pages per sheet (-twoup). The printer B declaration does the same as the
;; printer A declaration, the only difference is the printer name selection.
;;
;; There are other command line options like:
;;
;; -mono Render in monochrome as 1bit/pixel (only black and white).
;; -grey Render in greyscale as 8bits/pixel.
;; -color Render in color as 24bits/pixel.
;;
;; The default is `-mono'. So, printer A and B in the example above are
;; using implicitly the `-mono' option. Note that in `-mono' no gray tone
;; or color is printed, this includes the zebra stripes, that is, in `-mono'
;; the zebra stripes are not printed.
;;
;; See also documentation for `pr-ps-printer-alist'.
;;
;;
;; Using `printing'
;; ----------------
;;
;; To use `printing' insert in your init file:
;;
;; (require 'printing)
;; ;; ...some user settings...
;; (pr-update-menus t)
;;
;; During `pr-update-menus' evaluation:
;; * On Emacs 20:
;; it replaces the Tools/Print menu by Tools/Printing menu.
;; * On Emacs 21:
;; it replaces the File/Print* menu entries by File/Print menu.
;; Please, see section Menu Layout below for menu explanation.
;;
;; To use `printing' utilities you can use the Printing menu options, type M-x
;; followed by one of the commands below, or type a key associated with the
;; command you want (if there is a key binding).
;;
;; `printing' has the following commands:
;;
;; pr-interface
;; pr-ps-directory-preview
;; pr-ps-directory-using-ghostscript
;; pr-ps-directory-print
;; pr-ps-directory-ps-print
;; pr-ps-buffer-preview

;; pr-help
;; pr-ps-name
;; pr-txt-name
;; pr-ps-utility
;; pr-show-ps-setup
;; pr-show-pr-setup
;; pr-show-lpr-setup
;;
;; The general meanings of above commands are:
;;
;; PREFIX:
;; `pr-interface' buffer interface for printing package.
;; `pr-help' help for printing package.
;; `pr-ps-name' interactively select a PostScript printer.
;; `pr-txt-name' interactively select a text printer.
;; `pr-ps-utility' interactively select a PostScript utility.
;; `pr-show-*-setup' show current settings.
;; `pr-ps-*' deal with PostScript code generation.
;; `pr-txt-*' deal with text generation.
;; `pr-toggle-*' toggle on/off some boolean variable.
;; `pr-despool-*' despool the PostScript spooling buffer.
;; `pr-printify-*' replace nonprintable ASCII by printable ASCII
;; representation.
;;
;; SUFFIX:
;; `*-customize' customization.
;; `*-preview' preview a PostScript file.
;; `*-using-ghostscript' use ghostscript to print.
;; `*-fast-fire' fast fire command (see it for documentation).
;; `*-print' send PostScript directly to printer.
;; `*-ps-print' send PostScript directly to printer or use
;; ghostscript to print. It depends on
;; `pr-print-using-ghostscript' option.
;;
;; INFIX/SUFFIX:
;; `*-directory*' process a directory.
;; `*-buffer*' process a buffer.
;; `*-region*' process a region.
;; `*-mode*' process a major mode (see explanation below).
;; `*-file-*' process a PostScript file.
;; `*-file-up-*' process a PostScript file using a filter utility.
;;
;; Here are some examples:
;;
;; `pr-ps-buffer-using-ghostscript'
;; Use ghostscript to print a buffer.
;;
;; `pr-ps-file-print'
;; Print a PostScript file.
;;
;; `pr-toggle-spool'
;; Toggle spooling buffer.
;;
;; So you can preview through ghostview, use ghostscript to print (if you don't
;; have a PostScript printer) or send directly to printer a PostScript code
;; generated by `ps-print' package.
;;
;; Besides operating one buffer or region each time, you also can postpone
;; previewing or printing by saving the PostScript code generated in a
;; temporary Emacs buffer. This way you can save banner pages between
;; successive printing. You can toggle on/off spooling by invoking
;; `pr-toggle-spool' interactively or through menu bar.
;;
;; If you type, for example:
;;
;; C-u M-x pr-ps-buffer-print RET
;;
;; The `pr-ps-buffer-print' command prompts you for a n-up printing number and
;; a file name, and save the PostScript code generated to the file name instead
;; of sending to printer.
;;
;; This behavior is similar with the commands that deal with PostScript code
;; generation, that is, with `pr-ps-*' and `pr-despool-*' commands. If
;; spooling is on, only `pr-despool-*' commands prompt for a file name and save
;; the PostScript code spooled in this file.
;;
;; Besides the behavior described above, the `*-directory*' commands also
;; prompt for a directory and a file name regexp. So, it's possible to process
;; all or certain files on a directory at once (see also documentation for
;; `pr-list-directory').
;;
;; `printing' has also a special way to handle some major mode through
;; `*-mode*' commands. So it's possible to customize a major mode printing,
;; it's only needed to declare the customization in `pr-mode-alist' (see
;; section Options) and invoke some of `*-mode*' commands. An example for
;; major mode usage is when you're using gnus (or mh, or rmail, etc.) and
;; you're in the *Summary* buffer, if you forget to switch to the *Article*
;; buffer before printing, you'll get a nicely formatted list of article
;; subjects shows up at the printer. With major mode printing you don't need
;; to switch from gnus *Summary* buffer first.
;;
;; Current global keyboard mapping is:
;;
;; (global-set-key [print] 'pr-ps-fast-fire)
;; (global-set-key [M-print] 'pr-ps-mode-using-ghostscript)
;; (global-set-key [S-print] 'pr-ps-mode-using-ghostscript)
;; (global-set-key [C-print] 'pr-txt-fast-fire)
;; (global-set-key [C-M-print] 'pr-txt-fast-fire)
;;
;; As a suggestion of global keyboard mapping for some `printing' commands:
;;
;; (global-set-key "\C-ci" 'pr-interface)
;; (global-set-key "\C-cbp" 'pr-ps-buffer-print)
;; (global-set-key "\C-cbx" 'pr-ps-buffer-preview)

;;
;; See `pr-visible-entry-list' for hiding some parts of the menu.
;;
;; The menu has the following sections:
;;
;; A. Interface:
;;
;; 0. You can use a buffer interface instead of menus. It looks like the
;; customization buffer. Basically, it has the same options found in the
;; menu and some extra options, all this on a buffer.
;;
;; I. PostScript printing:
;;
;; 1. You can generate a PostScript file (if you type C-u before activating
;; menu) or PostScript temporary file for a directory, a buffer, a region
;; or a major mode, choosing 1-up, 2-up, 4-up or any other n-up printing;
;; after file generation, ghostview is activated using the file generated
;; as argument. This option is disabled if spooling is on (option 16).
;; Also, if you already have a PostScript file you can preview it.
;; Instead of previewing each buffer, region or major mode at once, you
;; can save temporarily the PostScript code generated in a buffer and
;; preview it later. The option `Despool...' despools the PostScript
;; spooling buffer in a temporary file and uses ghostview to preview it.
;; If you type C-u before choosing this option, the PostScript code
;; generated is saved in a file instead of saving in a temporary file.
;; To spool the PostScript code generated you need to turn on the option
;; 16. The option `Despool...' is enabled if spooling is on (option
;; 16).
;;
;; NOTE 1: It's possible to customize a major mode printing, just declare
;; the customization in `pr-mode-alist' and invoke some of
;; `*-mode*' commands or select Mode option in Printing menu. An
;; example for major mode usage is when you're using gnus (or mh,
;; or rmail, etc.) and you're in the *Summary* buffer, if you
;; forget to switch to the *Article* buffer before printing,
;; you'll get a nicely formatted list of article subjects shows
;; up at the printer. With major mode printing you don't need to
;; switch from gnus *Summary* buffer first.
;;
;; NOTE 2: There are the following options for PostScript file
;; processing:
;; Ia. Print the file *No Preprocessing*, that is, send it
;; directly to PostScript printer.
;; Ib. PostScript utility processing selection.
;; See `pr-ps-utility-alist' and `pr-setting-database' for
;; documentation.
;; Ic. Do n-up processing before printing.
;; Id. Toggle on/off landscape for PostScript file processing.
;; Ie. Toggle on/off duplex for PostScript file processing.
;; If. Toggle on/off tumble for PostScript file processing.
;;
;; NOTE 3: Don't forget to download and install the utilities declared on
;; `pr-ps-utility-alist'.
;;
;; 2. Operate the same way as option 1, but it sends directly the PostScript
;; code (or put in a file, if you've typed C-u) or it uses ghostscript to
;; print the PostScript file generated. It depends on option 18, if it's
;; turned on, it uses ghostscript; otherwise, it sends directly to
;; printer. If spooling is on (option 16), the PostScript code is saved
;; temporarily in a buffer instead of printing it or saving it in a file.
;; Also, if you already have a PostScript file you can print it. Instead
;; of printing each buffer, region or major mode at once, you can save
;; temporarily the PostScript code generated in a buffer and print it
;; later. The option `Despool...' despools the PostScript spooling
;; buffer directly on a printer. If you type C-u before choosing this
;; option, the PostScript code generated is saved in a file instead of
;; sending to printer. To spool the PostScript code generated you need
;; to turn on the option 16. This option is enabled if spooling is on
;; (option 16). See also the NOTE 1, NOTE 2 and NOTE 3 on option 1.
;;
;; 3. You can select a new PostScript printer to send PostScript code
;; generated. For selection it's used all PostScript printers defined
;; in `pr-ps-printer-alist' variable (see it for documentation).
;; See also `pr-setting-database'.
;;
;; II. Text printing:
;;
;; 4. If you have control characters (character code from \000 to \037) in a
;; buffer and you want to print them in a text printer, select this
;; option. All control characters in your buffer or region will be
;; replaced by a printable representation. The printable representations
;; use ^ (for ASCII control characters) or hex. The characters tab,
;; linefeed, space, return and formfeed are not affected. You don't need
;; to select this option if you use any option of section I, the
;; PostScript engine treats control characters properly.
;;
;; 5. If you want to print a directory, buffer, region or major mode in a
;; text printer, select this option. See also the NOTE 1 on option 1.
;;
;; 6. You can select a new text printer to send text generated. For
;; selection it's used all text printers defined in
;; `pr-txt-printer-alist' variable (see it for documentation).
;; See also `pr-setting-database'.
;;
;; III. PostScript page toggle options:
;;
;; 7. If you want a PostScript landscape printing, turn on this option.
;;
;; 8. If you want to have a header in each page in your PostScript code,
;; turn on this option.
;;
;; 9. If you want to draw a gaudy frame around the header, turn on this
;; option. This option is enabled if print header is on (option 8).
;;
;; 10. If you want that the line number is printed in your PostScript code,
;; turn on this option.
;;
;; 11. If you want background zebra stripes in your PostScript code, turn on
;; this option.
;;
;; 12. If you want a duplex printing and your PostScript printer has this
;; feature, turn on this option.
;;
;; 13. If you turned on duplex printing, you can choose if you want to have
;; a printing suitable for binding on the left or right (tumble off), or
;; to have a printing suitable for binding at top or bottom (tumble on).
;; This option is enabled if duplex is on (option 12).
;;
;; 14. If you want a PostScript upside-down printing, turn on this option.
;;
;; 15. With this option, you can choose if you want to print all pages, odd
;; pages, even pages, odd sheets or even sheets.
;; See also `ps-even-or-odd-pages'.
;;
;; IV. PostScript processing toggle options:
;;
;; 16. If you want to spool the PostScript code generated, turn on this
;; option. To spool the PostScript code generated use option 2. You
;; can despool later by choosing option 1 or 2, sub-option `Despool...'.
;;
;; 17. If you use colors in your buffers and want to see these colors on
;; your PostScript code generated, turn on this option. If you have a
;; black/white PostScript printer, these colors are displayed in gray
;; scale by PostScript printer interpreter.
;;
;; 18. If you don't have a PostScript printer to send PostScript files, turn
;; on this option. When this option is on, the ghostscript is used to
;; print PostScript files. In GNU or Unix system, if ghostscript is set
;; as a PostScript filter, you don't need to turn on this option.
;;
;; V. Printing customization:
;;
;; 19. If you want that region is automagically detected, turn on this
;; option. Note that this will only work if you're using transient mark
;; mode. When this option is on, the `*-buffer*' commands will behave
;; like `*-region*' commands, that is, `*-buffer*' commands will print
;; only the region marked instead of all buffer.
;;
;; 20. Turn this option on if you want that when current major-mode is
;; declared in `pr-mode-alist', the `*-buffer*' and `*-region*' commands
;; behave like `*-mode*' commands.
;;
;; 21. If you want that Printing menu stays open while you are setting
;; toggle options, turn on this option. The variables
;; `pr-menu-char-height' and `pr-menu-char-width' are used to guess the
;; menu position, so don't forget to adjust these variables if menu
;; position is not ok.
;;
;; VI. Customization:
;;
;; 22. Besides all options in section III, IV and V, you can customize much
;; more PostScript options in `ps-print' option. Or you can customize
;; some `lpr' options for text printing. Or customize `printing'
;; options.
;;
;; 23. Show current settings for `printing', `ps-print' or `lpr'.
;;
;; 24. Quick help for printing menu layout.
;;
;;
;; Option Settings
