12d89a2e | 48 | ;; About ps-print |
ef2cbb24 | 49 | ;; -------------- |
bcc0d457 | 50 | ;; |
0a5daee5 KH |
51 | ;; This package provides printing of Emacs buffers on PostScript printers; |
52 | ;; the buffer's bold and italic text attributes are preserved in the printer | |
53 | ;; output. ps-print is intended for use with Emacs or Lucid Emacs, together | |
54 | ;; with a fontifying package such as font-lock or hilit. | |
12d89a2e | 55 | ;; |
87a16a06 RS |
56 | ;; ps-print uses the same face attributes defined through font-lock or hilit |
57 | ;; to print a PostScript file, but some faces are better seeing on the screen | |
58 | ;; than on paper, specially when you have a black/white PostScript printer. | |
59 | ;; | |
60 | ;; ps-print allows a remap of face to another one that it is better to print, | |
61 | ;; for example, the face font-lock-comment-face (if you are using font-lock) | |
62 | ;; could have bold or italic attribute when printing, besides foreground color. | |
63 | ;; This remap improves printing look (see How Ps-Print Maps Faces). | |
64 | ;; | |
bcc0d457 | 65 | ;; |
12d89a2e | 66 | ;; Using ps-print |
ef2cbb24 | 67 | ;; -------------- |
ef2cbb24 | 68 | ;; |
d3ab8dac | 69 | ;; ps-print provides eight commands for generating PostScript images |
12d89a2e RS |
70 | ;; of Emacs buffers: |
71 | ;; | |
72 | ;; ps-print-buffer | |
73 | ;; ps-print-buffer-with-faces | |
74 | ;; ps-print-region | |
75 | ;; ps-print-region-with-faces | |
76 | ;; ps-spool-buffer | |
77 | ;; ps-spool-buffer-with-faces | |
78 | ;; ps-spool-region | |
79 | ;; ps-spool-region-with-faces | |
80 | ;; | |
81 | ;; These commands all perform essentially the same function: they | |
82 | ;; generate PostScript images suitable for printing on a PostScript | |
83 | ;; printer or displaying with GhostScript. These commands are | |
84 | ;; collectively referred to as "ps-print- commands". | |
85 | ;; | |
86 | ;; The word "print" or "spool" in the command name determines when the | |
87 | ;; PostScript image is sent to the printer: | |
ef2cbb24 | 88 | ;; |
12d89a2e RS |
89 | ;; print - The PostScript image is immediately sent to the |
90 | ;; printer; | |
ef2cbb24 | 91 | ;; |
12d89a2e RS |
92 | ;; spool - The PostScript image is saved temporarily in an |
93 | ;; Emacs buffer. Many images may be spooled locally | |
94 | ;; before printing them. To send the spooled images | |
bcc0d457 | 95 | ;; to the printer, use the command `ps-despool'. |
ef2cbb24 | 96 | ;; |
12d89a2e RS |
97 | ;; The spooling mechanism was designed for printing lots of small |
98 | ;; files (mail messages or netnews articles) to save paper that would | |
99 | ;; otherwise be wasted on banner pages, and to make it easier to find | |
100 | ;; your output at the printer (it's easier to pick up one 50-page | |
101 | ;; printout than to find 50 single-page printouts). | |
06fb6aab | 102 | ;; |
d3ab8dac | 103 | ;; ps-print has a hook in the `kill-emacs-hook' so that you won't |
a7acbbe4 | 104 | ;; accidentally quit from Emacs while you have unprinted PostScript |
12d89a2e RS |
105 | ;; waiting in the spool buffer. If you do attempt to exit with |
106 | ;; spooled PostScript, you'll be asked if you want to print it, and if | |
107 | ;; you decline, you'll be asked to confirm the exit; this is modeled | |
108 | ;; on the confirmation that Emacs uses for modified buffers. | |
109 | ;; | |
110 | ;; The word "buffer" or "region" in the command name determines how | |
111 | ;; much of the buffer is printed: | |
112 | ;; | |
113 | ;; buffer - Print the entire buffer. | |
114 | ;; | |
115 | ;; region - Print just the current region. | |
116 | ;; | |
117 | ;; The -with-faces suffix on the command name means that the command | |
118 | ;; will include font, color, and underline information in the | |
119 | ;; PostScript image, so the printed image can look as pretty as the | |
120 | ;; buffer. The ps-print- commands without the -with-faces suffix | |
121 | ;; don't include font, color, or underline information; images printed | |
122 | ;; with these commands aren't as pretty, but are faster to generate. | |
123 | ;; | |
124 | ;; Two ps-print- command examples: | |
125 | ;; | |
126 | ;; ps-print-buffer - print the entire buffer, | |
127 | ;; without font, color, or | |
128 | ;; underline information, and | |
129 | ;; send it immediately to the | |
130 | ;; printer. | |
131 | ;; | |
132 | ;; ps-spool-region-with-faces - print just the current region; | |
133 | ;; include font, color, and | |
134 | ;; underline information, and | |
135 | ;; spool the image in Emacs to | |
136 | ;; send to the printer later. | |
137 | ;; | |
138 | ;; | |
139 | ;; Invoking Ps-Print | |
bcc0d457 | 140 | ;; ----------------- |
ef2cbb24 | 141 | ;; |
12d89a2e | 142 | ;; To print your buffer, type |
ef2cbb24 | 143 | ;; |
12d89a2e | 144 | ;; M-x ps-print-buffer |
ef2cbb24 | 145 | ;; |
12d89a2e RS |
146 | ;; or substitute one of the other seven ps-print- commands. The |
147 | ;; command will generate the PostScript image and print or spool it as | |
148 | ;; specified. By giving the command a prefix argument | |
149 | ;; | |
150 | ;; C-u M-x ps-print-buffer | |
151 | ;; | |
152 | ;; it will save the PostScript image to a file instead of sending it | |
153 | ;; to the printer; you will be prompted for the name of the file to | |
154 | ;; save the image to. The prefix argument is ignored by the commands | |
155 | ;; that spool their images, but you may save the spooled images to a | |
bcc0d457 | 156 | ;; file by giving a prefix argument to `ps-despool': |
12d89a2e RS |
157 | ;; |
158 | ;; C-u M-x ps-despool | |
159 | ;; | |
bcc0d457 | 160 | ;; When invoked this way, `ps-despool' will prompt you for the name of |
12d89a2e RS |
161 | ;; the file to save to. |
162 | ;; | |
bcc0d457 RS |
163 | ;; Any of the `ps-print-' commands can be bound to keys; I recommend |
164 | ;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces', | |
165 | ;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard: | |
12d89a2e RS |
166 | ;; |
167 | ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc | |
ef2cbb24 RS |
168 | ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces) |

bcc0d457 | 175 | ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what |
12d89a2e | 176 | ;; command is used to send the PostScript images to the printer, and |
bcc0d457 RS |
177 | ;; what arguments to give the command. These are analogous to |
178 | ;; `lpr-command' and `lpr-switches'. | |
87a16a06 | 179 | ;; |
bcc0d457 RS |
180 | ;; Make sure that they contain appropriate values for your system; |
181 | ;; see the usage notes below and the documentation of these variables. | |
182 | ;; | |
bc0d41bd | 183 | ;; The variable `ps-printer-name' determines the name of a local printer for |

188 | ;; `lpr-command' set to invoke a pretty-printer such as `enscript', | |
189 | ;; then ps-print won't work properly. `ps-lpr-command' must name | |
12d89a2e | 190 | ;; a program that does not format the files it prints. |
d3ab8dac KH |
191 | ;; `ps-printer-name' takes its initial value from the variable |

bc0d41bd KH |
194 | ;; The variable `ps-print-region-function' specifies a function to print the |
195 | ;; region on a PostScript printer. | |
196 | ;; See definition of `call-process-region' for calling conventions. The fourth | |

198 | ;; | |
8e234846 GM |
199 | ;; The variable `ps-manual-feed' indicates if the printer will manually feed |

222 | ;; PostScript printer doesn't have a paper with the size indicated by | |
223 | ;; `ps-paper-type', instead it uses the default paper size. If variable | |
224 | ;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer | |

226 | ;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex | |
227 | ;; Printers). The default value is non-nil (it gives an error). | |
228 | ;; | |
906d41a7 GM |
229 | ;; The variable `ps-landscape-mode' determines the orientation of the printing |
230 | ;; on the page: nil means `portrait' mode, non-nil means `landscape' mode. | |
bcc0d457 | 231 | ;; There is no oblique mode yet, though this is easy to do in ps. |

bcc0d457 | 240 | ;; You can use: |
906d41a7 GM |
241 | ;; - (the standard) one column portrait mode. |
242 | ;; - (my favorite) two columns landscape mode (which spares trees). | |
243 | ;; but also: | |
bcc0d457 | 244 | ;; - one column landscape mode for files with very long lines. |
906d41a7 GM |
245 | ;; - multi-column portrait or landscape mode. |
246 | ;; | |
247 | ;; The variable `ps-print-upside-down' determines other orientation for printing | |
248 | ;; page: nil means `normal' printing, non-nil means `upside-down' printing. The | |
249 | ;; default value is nil (`normal' printing). | |
250 | ;; | |
251 | ;; The `upside-down' orientation can be used in portrait or landscape mode. | |
12d89a2e | 252 | ;; |
1fd9b7fe GM |
253 | ;; The variable `ps-selected-pages' specifies which pages to print. If it's |

369 | ;; The amount of information in the header can be changed by changing | |
bcc0d457 | 370 | ;; the number of lines. To show less, set `ps-header-lines' to 1, and |
12d89a2e | 371 | ;; the header will show only the buffer name and page number. To show |
bcc0d457 | 372 | ;; more, set `ps-header-lines' to 3, and the header will show the time of |
12d89a2e RS |
373 | ;; printing below the date. |
374 | ;; | |
375 | ;; To change the content of the headers, change the variables | |
bcc0d457 RS |
376 | ;; `ps-left-header' and `ps-right-header'. |
377 | ;; These variables are lists, specifying top-to-bottom the text | |
378 | ;; to display on the left or right side of the header. | |
379 | ;; Each element of the list should be a string or a symbol. | |
380 | ;; Strings are inserted directly into the PostScript arrays, | |
381 | ;; and should contain the PostScript string delimiters '(' and ')'. | |
12d89a2e RS |
382 | ;; |
383 | ;; Symbols in the header format lists can either represent functions | |
384 | ;; or variables. Functions are called, and should return a string to | |
385 | ;; show in the header. Variables should contain strings to display in | |
386 | ;; the header. In either case, function or variable, the PostScript | |
a7acbbe4 | 387 | ;; string delimiters are added by ps-print, and should not be part of |
12d89a2e RS |
388 | ;; the returned value. |
389 | ;; | |
390 | ;; Here's an example: say we want the left header to display the text | |
391 | ;; | |
392 | ;; Moe | |
393 | ;; Larry | |
394 | ;; Curly | |
395 | ;; | |
396 | ;; where we have a function to return "Moe" | |
397 | ;; | |
398 | ;; (defun moe-func () | |
399 | ;; "Moe") | |
400 | ;; | |
401 | ;; a variable specifying "Larry" | |
402 | ;; | |
403 | ;; (setq larry-var "Larry") | |
404 | ;; | |
bcc0d457 | 405 | ;; and a literal for "Curly". Here's how `ps-left-header' should be |
12d89a2e RS |
406 | ;; set: |
407 | ;; | |
408 | ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)")) | |
409 | ;; | |
410 | ;; Note that Curly has the PostScript string delimiters inside his | |
bcc0d457 | 411 | ;; quotes -- those aren't misplaced lisp delimiters! |
87a16a06 | 412 | ;; |
bcc0d457 RS |
413 | ;; Without them, PostScript would attempt to call the undefined |
414 | ;; function Curly, which would result in a PostScript error. | |
87a16a06 | 415 | ;; |
bcc0d457 RS |
416 | ;; Since most printers don't report PostScript errors except by |
417 | ;; aborting the print job, this kind of error can be hard to track down. | |

422 | ;; PostScript Prologue Header |
423 | ;; -------------------------- | |
424 | ;; | |
425 | ;; It is possible to add PostScript prologue header comments besides that | |
426 | ;; ps-print generates by setting the variable `ps-print-prologue-header'. | |
427 | ;; | |
bc0d41bd KH |
428 | ;; `ps-print-prologue-header' may be a string or a symbol function which returns |
429 | ;; a string. Note that this string is inserted on PostScript prologue header | |
430 | ;; section which is used to define some document characteristic through | |
d3ab8dac KH |
431 | ;; PostScript special comments, like "%%Requirements: jog\n". |
432 | ;; | |
433 | ;; By default `ps-print-prologue-header' is nil. | |
434 | ;; | |
435 | ;; ps-print always inserts the %%Requirements: comment, so if you need to insert | |
436 | ;; more requirements put them first in `ps-print-prologue-header' using the | |
437 | ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on | |
438 | ;; requirements and set %%LanguageLevel: to 2, do: | |
439 | ;; | |
440 | ;; (setq ps-print-prologue-header | |
441 | ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n") | |
442 | ;; | |
443 | ;; The duplex requirement is inserted by ps-print (see section Duplex Printers). | |
444 | ;; | |
445 | ;; Do not forget to terminate the string with "\n". | |

452 | ;; It is also possible to add an user defined PostScript prologue code before |
453 | ;; all generated prologue code by setting the variable | |
454 | ;; `ps-user-defined-prologue'. | |
455 | ;; | |
456 | ;; `ps-user-defined-prologue' may be a string or a symbol function which returns | |
457 | ;; a string. Note that this string is inserted after `ps-adobe-tag' and | |
458 | ;; PostScript prologue comments, and before ps-print PostScript prologue code | |
459 | ;; section. That is, this string is inserted after error handler initialization | |
460 | ;; and before ps-print settings. | |
461 | ;; | |
462 | ;; By default `ps-user-defined-prologue' is nil. | |
463 | ;; | |
66e63857 GM |
464 | ;; It's strongly recommended only insert PostScript code and/or comments |
465 | ;; specific for your printing system particularities. For example, some special | |
466 | ;; initialization that only your printing system needs. | |
467 | ;; | |
468 | ;; Do not insert code for duplex printing, n-up printing or error handler, | |

794 | ;; ps-print now knows rather precisely some fonts: the variable |
795 | ;; `ps-font-info-database' contains information for a list of font families | |
796 | ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' `Helvetica-Narrow' | |
797 | ;; `NewCenturySchlbk'). Each font family contains the font names for standard, | |
798 | ;; bold, italic and bold-italic characters, a reference size (usually 10) and | |
799 | ;; the corresponding line height, width of a space and average character width. | |
06fb6aab | 800 | ;; |
7d8b7e8e KH |
801 | ;; The variable `ps-font-family' determines which font family is to be used for |
802 | ;; ordinary text. If its value does not correspond to a known font family, an | |
803 | ;; error message is printed into the `*Messages*' buffer, which lists the | |
804 | ;; currently available font families. | |
bcc0d457 | 805 | ;; |
7d8b7e8e KH |
806 | ;; The variable `ps-font-size' determines the size (in points) of the font for |
807 | ;; ordinary text, when generating PostScript. Its value is a float or a cons of | |
808 | ;; floats which has the following form: | |
bcc0d457 | 809 | ;; |
7d8b7e8e KH |
810 | ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE) |
811 | ;; | |
812 | ;; Similarly, the variable `ps-header-font-family' determines which font family | |
813 | ;; is to be used for text in the header. | |
814 | ;; | |
815 | ;; The variable `ps-header-font-size' determines the font size, in points, for | |
816 | ;; text in the header (similar to `ps-font-size'). | |
817 | ;; | |
818 | ;; The variable `ps-header-title-font-size' determines the font size, in points, | |
819 | ;; for the top line of text in the header (similar to `ps-font-size'). | |

12b88fff | 822 | ;; Adding a New Font Family |
bcc0d457 RS |
823 | ;; ------------------------ |
824 | ;; | |
825 | ;; To use a new font family, you MUST first teach ps-print | |
87a16a06 | 826 | ;; this font, i.e., add its information to `ps-font-info-database', |
bcc0d457 RS |
827 | ;; otherwise ps-print cannot correctly place line and page breaks. |
828 | ;; | |
87a16a06 | 829 | ;; For example, assuming `Helvetica' is unknown, |
bcc0d457 RS |
830 | ;; you first need to do the following ONLY ONCE: |
831 | ;; | |
832 | ;; - create a new buffer | |
833 | ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer) | |
834 | ;; - open this file and find the line: | |
1fd9b7fe | 835 | ;; `% 3 cm 20 cm moveto 10/Courier ReportFontInfo showpage' |
a18ed129 | 836 | ;; - delete the leading `%' (which is the PostScript comment character) |
bcc0d457 RS |
837 | ;; - replace in this line `Courier' by the new font (say `Helvetica') |
838 | ;; to get the line: | |
1fd9b7fe | 839 | ;; `3 cm 20 cm moveto 10/Helvetica ReportFontInfo showpage' |
bcc0d457 RS |
840 | ;; - send this file to the printer (or to ghostscript). |
841 | ;; You should read the following on the output page: | |
842 | ;; | |
843 | ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78 | |
844 | ;; and a crude estimate of average character width is 5.09243 | |
845 | ;; | |
846 | ;; - Add these values to the `ps-font-info-database': | |
847 | ;; (setq ps-font-info-database | |
12b88fff RS |
848 | ;; (append |
849 | ;; '((Helvetica ; the family key | |
850 | ;; (fonts (normal . "Helvetica") | |
851 | ;; (bold . "Helvetica-Bold") | |
852 | ;; (italic . "Helvetica-Oblique") | |

854 | ;; (size . 10.0) | |
855 | ;; (line-height . 11.56) | |
856 | ;; (space-width . 2.78) | |
857 | ;; (avg-char-width . 5.09243))) | |
858 | ;; ps-font-info-database)) | |
bcc0d457 RS |
859 | ;; - Now you can use this font family with any size: |
860 | ;; (setq ps-font-family 'Helvetica) | |
861 | ;; - if you want to use this family in another emacs session, you must | |
862 | ;; put into your `~/.emacs': | |
863 | ;; (require 'ps-print) | |
864 | ;; (setq ps-font-info-database (append ...))) | |
865 | ;; if you don't want to load ps-print, you have to copy the whole value: | |
866 | ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>)) | |
12b88fff RS |
867 | ;; or, use `ps-print-hook' (see section Hooks): |
868 | ;; (add-hook 'ps-print-hook | |
bc0d41bd KH |
869 | ;; '(lambda () |
870 | ;; (or (assq 'Helvetica ps-font-info-database) | |
871 | ;; (setq ps-font-info-database (append ...))))) | |
bcc0d457 RS |
872 | ;; |
873 | ;; You can create new `mixed' font families like: | |
12b88fff RS |
874 | ;; (my-mixed-family |
875 | ;; (fonts (normal . "Courier-Bold") | |

879 | ;; (w3-table-hack-x-face . "LineDrawNormal")) | |
880 | ;; (size . 10.0) | |
881 | ;; (line-height . 10.55) | |
882 | ;; (space-width . 6.0) | |
883 | ;; (avg-char-width . 6.0)) | |
d3ab8dac | 884 | ;; |
bcc0d457 RS |
885 | ;; Now you can use your new font family with any size: |
886 | ;; (setq ps-font-family 'my-mixed-family) | |
887 | ;; | |
12b88fff RS |
888 | ;; Note that on above example the `w3-table-hack-x-face' entry refers to |
889 | ;; a face symbol, so when printing this face it'll be used the font | |
890 | ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to | |
891 | ;; use bold and/or italic attribute, the corresponding entry (bold, italic | |
892 | ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry. | |
893 | ;; | |
894 | ;; Note also that the font family entry order is irrelevant, so the above | |
895 | ;; example could also be written: | |
896 | ;; (my-mixed-family | |
897 | ;; (size . 10.0) | |
898 | ;; (fonts (w3-table-hack-x-face . "LineDrawNormal") | |
899 | ;; (bold . "Helvetica") | |
900 | ;; (bold-italic . "NewCenturySchlbk-BoldItalic") | |
901 | ;; (italic . "Zapf-Chancery-MediumItalic") | |
902 | ;; (normal . "Courier-Bold")) | |
903 | ;; (avg-char-width . 6.0) | |
904 | ;; (space-width . 6.0) | |
905 | ;; (line-height . 10.55)) | |
906 | ;; | |
907 | ;; Despite the note above, it is recommended that some convention about | |
908 | ;; entry order be used. | |
909 | ;; | |
bcc0d457 RS |
910 | ;; You can get information on all the fonts resident in YOUR printer |
911 | ;; by uncommenting the line: | |
912 | ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage | |
913 | ;; | |
a18ed129 RS |
914 | ;; The PostScript file should be sent to YOUR PostScript printer. |
915 | ;; If you send it to ghostscript or to another PostScript printer, | |
bcc0d457 | 916 | ;; you may get slightly different results. |
c3d6d211 GM |
917 | ;; Anyway, as ghostscript fonts are autoload, you won't get much font info. |
918 | ;; | |
919 | ;; Note also that ps-print DOESN'T download any font to your printer, instead | |
920 | ;; it uses the fonts resident in your printer. | |

923 | ;; How Ps-Print Deals With Faces | |
924 | ;; ----------------------------- | |
12d89a2e | 925 | ;; |
bcc0d457 RS |
926 | ;; The ps-print-*-with-faces commands attempt to determine which faces |
927 | ;; should be printed in bold or italic, but their guesses aren't | |
928 | ;; always right. For example, you might want to map colors into faces | |
929 | ;; so that blue faces print in bold, and red faces in italic. | |
12d89a2e | 930 | ;; |
857686a6 RS |
931 | ;; It is possible to force ps-print to consider specific faces bold, |
932 | ;; italic or underline, no matter what font they are displayed in, by setting | |
933 | ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'. | |
934 | ;; These variables contain lists of faces that ps-print should consider bold, | |
935 | ;; italic or underline; to set them, put code like the following into your | |
936 | ;; .emacs file: | |
12d89a2e | 937 | ;; |
12b88fff | 938 | ;; (setq ps-bold-faces '(my-blue-face)) |
bcc0d457 | 939 | ;; (setq ps-italic-faces '(my-red-face)) |
857686a6 | 940 | ;; (setq ps-underlined-faces '(my-green-face)) |
bcc0d457 RS |
941 | ;; |
942 | ;; Faces like bold-italic that are both bold and italic should go in | |
943 | ;; *both* lists. | |
944 | ;; | |
d3ab8dac | 945 | ;; ps-print keeps internal lists of which fonts are bold and which are |
bcc0d457 RS |
946 | ;; italic; these lists are built the first time you invoke ps-print. |
947 | ;; For the sake of efficiency, the lists are built only once; the same | |
948 | ;; lists are referred in later invocations of ps-print. | |
949 | ;; | |
950 | ;; Because these lists are built only once, it's possible for them to | |
951 | ;; get out of sync, if a face changes, or if new faces are added. To | |
952 | ;; get the lists back in sync, you can set the variable | |
953 | ;; `ps-build-face-reference' to t, and the lists will be rebuilt the | |
857686a6 RS |
954 | ;; next time ps-print is invoked. If you need that the lists always be |
955 | ;; rebuilt when ps-print is invoked, set the variable | |
956 | ;; `ps-always-build-face-reference' to t. | |
bcc0d457 | 957 | ;; |
906d41a7 GM |
958 | ;; If you need to print without worrying about face background color, set the |
959 | ;; variable `ps-use-face-background' which specifies if face background should | |
960 | ;; be used. Valid values are: | |
961 | ;; | |
962 | ;; t always use face background color. | |
963 | ;; nil never use face background color. | |
964 | ;; (face...) list of faces whose background color will be used. | |
965 | ;; | |
966 | ;; Any other value will be treated as t. | |
967 | ;; The default value is t. | |

970 | ;; How Ps-Print Deals With Color | |
971 | ;; ----------------------------- | |

bcc0d457 RS |
974 | ;; defined and embeds color information in the PostScript image. |

976 | ;; variables `ps-default-fg' and `ps-default-bg'. | |
6e1b1da6 | 977 | ;; On black-and-white printers, colors are displayed in gray scale. |

87a16a06 RS |
981 | ;; How Ps-Print Maps Faces |
982 | ;; ----------------------- | |
983 | ;; | |
984 | ;; As ps-print uses PostScript to print buffers, it is possible to have | |
985 | ;; other attributes associated with faces. So the new attributes used | |
986 | ;; by ps-print are: | |
987 | ;; | |
988 | ;; strikeout - like underline, but the line is in middle of text. | |
989 | ;; overline - like underline, but the line is over the text. | |
990 | ;; shadow - text will have a shadow. | |
991 | ;; box - text will be surrounded by a box. | |
a18ed129 | 992 | ;; outline - print characters as hollow outlines. |
87a16a06 | 993 | ;; |
06fb6aab | 994 | ;; See the documentation for `ps-extend-face'. |
87a16a06 | 995 | ;; |
bc0d41bd KH |
996 | ;; Let's, for example, remap `font-lock-keyword-face' to another foreground |
997 | ;; color and bold attribute: | |
87a16a06 | 998 | ;; |
a18ed129 | 999 | ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE) |
87a16a06 | 1000 | ;; |
6c8f2753 RS |
1001 | ;; If you want to use a new face, define it first with `defface', |
1002 | ;; and then call `ps-extend-face' to specify how to print it. | |

1005 | ;; How Ps-Print Has A Text And/Or Image On Background | |
1006 | ;; -------------------------------------------------- | |
1007 | ;; | |
d3ab8dac | 1008 | ;; ps-print can print texts and/or EPS PostScript images on background; it is |
87a16a06 RS |
1009 | ;; possible to define the following text attributes: font name, font size, |
1010 | ;; initial position, angle, gray scale and pages to print. | |
1011 | ;; | |
1012 | ;; It has the following EPS PostScript images attributes: file name containing | |
1013 | ;; the image, initial position, X and Y scales, angle and pages to print. | |
1014 | ;; | |
1015 | ;; See documentation for `ps-print-background-text' and | |
1016 | ;; `ps-print-background-image'. | |
1017 | ;; | |
1018 | ;; For example, if we wish to print text "preliminary" on all pages and text | |
1019 | ;; "special" on page 5 and from page 11 to page 17, we could specify: | |
1020 | ;; | |
1021 | ;; (setq ps-print-background-text | |
1022 | ;; '(("preliminary") | |
1023 | ;; ("special" | |
1024 | ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position | |
1025 | ;; ; (upper left corner) | |
1026 | ;; nil nil nil | |
12b88fff | 1027 | ;; "PrintHeight neg PrintPageWidth atan" ; angle |
87a16a06 RS |
1028 | ;; 5 (11 . 17)) ; page list |
1029 | ;; )) | |
1030 | ;; | |
1031 | ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and | |
1032 | ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we | |
1033 | ;; specify: | |
1034 | ;; | |
1035 | ;; (setq ps-print-background-image | |
1036 | ;; '(("~/images/EPS-image1.ps" | |
1037 | ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner) | |
1038 | ;; ("~/images/EPS-image2.ps" | |
1039 | ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position | |
1040 | ;; ; (upper left corner) | |
1041 | ;; nil nil nil | |
1042 | ;; 5 (11 . 17)) ; page list | |
1043 | ;; )) | |
1044 | ;; | |
1045 | ;; If it is not possible to read (or does not exist) an image file, that file | |
1046 | ;; is ignored. | |
1047 | ;; | |
1048 | ;; The printing order is: | |

6e1b1da6 GM |
1050 | ;; 1. Print background color |
1051 | ;; 2. Print zebra stripes | |

1543 | On MS-DOS and MS-Windows systems, a string value is taken as the name of | |
1544 | the printer device or port to which PostScript files are written, | |
1545 | provided `ps-lpr-command' is \"\". By default it is the same as | |
1546 | `printer-name'; typical non-default settings would be \"LPT1\" to | |
1547 | \"LPT3\" for parallel printers, or \"COM1\" to \"COM4\" or \"AUX\" for | |
1548 | serial printers, or \"//hostname/printer\" for a shared network printer. | |
1549 | You can also set it to a name of a file, in which case the output gets | |
1550 | appended to that file. \(Note that `ps-print' package already has | |
1551 | facilities for printing to a file, so you might as well use them instead | |
270a64ac | 1552 | of changing the setting of this variable.\) If you want to silently |
