150 ;; --------------

151 ;;

|
152 ;; This package provides printing of Emacs buffers on PostScript
|
|
|
153 ;; printers; the buffer's bold and italic text attributes are
|
|
|
154 ;; preserved in the printer output. Ps-print is intended for use with
|
|
|
155 ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
|
|
|
156 ;; font-lock or hilit.

|
|
|
160 ;; --------------
|
|
|
161 ;;
|
|
|
162 ;; The Commands
|
|
|
163 ;;
|
|
|
164 ;; Ps-print provides eight commands for generating PostScript images
|
|
|
165 ;; of Emacs buffers:
|
|
|
166 ;;
|
|
|
167 ;; ps-print-buffer
|
|
|
168 ;; ps-print-buffer-with-faces
|
|
|
169 ;; ps-print-region
|
|
|
170 ;; ps-print-region-with-faces
|
|
|
171 ;; ps-spool-buffer
|
|
|
172 ;; ps-spool-buffer-with-faces
|
|
|
173 ;; ps-spool-region
|
|
|
174 ;; ps-spool-region-with-faces
|
|
|
175 ;;
|
|
|
176 ;; These commands all perform essentially the same function: they
|
|
|
177 ;; generate PostScript images suitable for printing on a PostScript
|
|
|
178 ;; printer or displaying with GhostScript. These commands are
|
|
|
179 ;; collectively referred to as "ps-print- commands".
|
|
|
180 ;;
|
|
|
181 ;; The word "print" or "spool" in the command name determines when the
|
|
|
182 ;; PostScript image is sent to the printer:
|
|
|
183 ;;
|
|
|
184 ;; print - The PostScript image is immediately sent to the
|
|
|
185 ;; printer;
|
|
|
186 ;;
|
|
|
187 ;; spool - The PostScript image is saved temporarily in an
|
|
|
188 ;; Emacs buffer. Many images may be spooled locally
|
|
|
189 ;; before printing them. To send the spooled images
|
|
16
|
190 ;; to the printer, use the command `ps-despool'.
|
|
0
|
191 ;;
|
|
|
192 ;; The spooling mechanism was designed for printing lots of small
|
|
|
193 ;; files (mail messages or netnews articles) to save paper that would
|
|
|
194 ;; otherwise be wasted on banner pages, and to make it easier to find
|
|
|
195 ;; your output at the printer (it's easier to pick up one 50-page
|
|
|
196 ;; printout than to find 50 single-page printouts).
|
|
|
197 ;;
|
|
16
|
198 ;; Ps-print has a hook in the `kill-emacs-hooks' so that you won't
|
|
2
|
199 ;; accidentally quit from Emacs while you have unprinted PostScript
|
|
0
|
200 ;; waiting in the spool buffer. If you do attempt to exit with
|
|
|
201 ;; spooled PostScript, you'll be asked if you want to print it, and if
|
|
|
202 ;; you decline, you'll be asked to confirm the exit; this is modeled
|
|
|
203 ;; on the confirmation that Emacs uses for modified buffers.
|
|
|
204 ;;
|
|
|
205 ;; The word "buffer" or "region" in the command name determines how
|
|
|
206 ;; much of the buffer is printed:
|
|
|
207 ;;
|
|
|
208 ;; buffer - Print the entire buffer.
|
|
|
209 ;;
|
|
|
210 ;; region - Print just the current region.
|
|
|
211 ;;
|
|
|
212 ;; The -with-faces suffix on the command name means that the command
|
|
|
213 ;; will include font, color, and underline information in the
|
|
|
214 ;; PostScript image, so the printed image can look as pretty as the
|
|
|
215 ;; buffer. The ps-print- commands without the -with-faces suffix
|
|
|
216 ;; don't include font, color, or underline information; images printed
|
|
|
217 ;; with these commands aren't as pretty, but are faster to generate.
|
|
|
218 ;;
|
|
|
219 ;; Two ps-print- command examples:
|
|
|
220 ;;
|
|
|
221 ;; ps-print-buffer - print the entire buffer,
|
|
|
222 ;; without font, color, or
|
|
|
223 ;; underline information, and
|
|
|
224 ;; send it immediately to the
|
|
|
225 ;; printer.
|
|
|
226 ;;
|
|
|
227 ;; ps-spool-region-with-faces - print just the current region;
|
|
|
228 ;; include font, color, and
|
|
|
229 ;; underline information, and
|
|
|
230 ;; spool the image in Emacs to
|
|
|
231 ;; send to the printer later.

|
|

|
240 ;;

|
|
|
242 ;; command will generate the PostScript image and print or spool it as

|
243 ;; specified. By giving the command a prefix argument

244 ;;
|
|
|
245 ;; C-u M-x ps-print-buffer
|
|
|
246 ;;

|
|
|
248 ;; to the printer; you will be prompted for the name of the file to
|
|
|
249 ;; save the image to. The prefix argument is ignored by the commands
|
|
|
250 ;; that spool their images, but you may save the spooled images to a

251 ;; file by giving a prefix argument to `ps-despool':

|
|
|
490 ;; ------------------------
|
|
|
491 ;;
|
|
|
492 ;; To use a new font family, you MUST first teach ps-print
|
|
|
493 ;; this font, i.e., add its information to `ps-font-info-database',
|
|
|
494 ;; otherwise ps-print cannot correctly place line and page breaks.
|
|
|
495 ;;
|
|
|
496 ;; For example, assuming `Helvetica' is unknown,
|
|
|
497 ;; you first need to do the following ONLY ONCE:
|
|
|
498 ;;
|
|
|
499 ;; - create a new buffer
|
|
|
500 ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
|
|
|
501 ;; - open this file and find the line:
|
|
|
502 ;; `% 3 cm 20 cm moveto 10 /Courier ReportFontInfo showpage'
|
|
|
503 ;; - delete the leading `%' (which is the Postscript comment character)
|
|
|
504 ;; - replace in this line `Courier' by the new font (say `Helvetica')
|
|
|
505 ;; to get the line:
|
|
|
506 ;; `3 cm 20 cm moveto 10 /Helvetica ReportFontInfo showpage'
|
|
|
507 ;; - send this file to the printer (or to ghostscript).
|
|
|
508 ;; You should read the following on the output page:
|
|
|
509 ;;
|
|
|
510 ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
|
|
|
511 ;; and a crude estimate of average character width is 5.09243
|
|
|
512 ;;
|
|
|
513 ;; - Add these values to the `ps-font-info-database':
|
|
|
514 ;; (setq ps-font-info-database
|
|
|
515 ;; (append
|
|
|
516 ;; '((Helvetica ; the family name
|
|
|
517 ;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique"
|

518 ;; 10.0 11.56 2.78 5.09243))
|
|
|
519 ;; ps-font-info-database))
|
|
|
520 ;; - Now you can use this font family with any size:
|
|
|
521 ;; (setq ps-font-family 'Helvetica)
|
|
|
522 ;; - if you want to use this family in another emacs session, you must
|
|
|
523 ;; put into your `~/.emacs':
|
|
|
524 ;; (require 'ps-print)
|
|
|
525 ;; (setq ps-font-info-database (append ...)))
|
|
|
526 ;; if you don't want to load ps-print, you have to copy the whole value:
|
|
|
527 ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
|
|
|
528 ;; or, if you can wait until the `ps-print-hook' is implemented, do:
|
|
|
529 ;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...)))
|
|
|
530 ;; This does not work yet, since there is no `ps-print-hook' yet.

551 ;; How Ps-Print Deals With Faces
|
|
|
552 ;; -----------------------------
|
|
|
553 ;;
|
|
|
554 ;; The ps-print-*-with-faces commands attempt to determine which faces
|
|
|
555 ;; should be printed in bold or italic, but their guesses aren't
|
|
|
556 ;; always right. For example, you might want to map colors into faces
|
|
|
557 ;; so that blue faces print in bold, and red faces in italic.
|
|
|
558 ;;
|
|
|
559 ;; It is possible to force ps-print to consider specific faces bold or
|
|
|
560 ;; italic, no matter what font they are displayed in, by setting the
|
|
|
561 ;; variables `ps-bold-faces' and `ps-italic-faces'. These variables
|
|
|
562 ;; contain lists of faces that ps-print should consider bold or
|
|
|
563 ;; italic; to set them, put code like the following into your .emacs
|
|
|
564 ;; file:
|
|
|
565 ;;
|
|
|
566 ;; (setq ps-bold-faces '(my-blue-face))
|
|
|
567 ;; (setq ps-italic-faces '(my-red-face))
|
|
|
568 ;;
|
|
|
569 ;; Faces like bold-italic that are both bold and italic should go in
|
|
|
570 ;; *both* lists.
|
|
0
|
571 ;;
|
|
16
|
572 ;; Ps-print keeps internal lists of which fonts are bold and which are
|
|
|
573 ;; italic; these lists are built the first time you invoke ps-print.
|
|
|
574 ;; For the sake of efficiency, the lists are built only once; the same
|
|
|
575 ;; lists are referred in later invocations of ps-print.
|
|
|
576 ;;
|
|
|
577 ;; Because these lists are built only once, it's possible for them to
|
|
|
578 ;; get out of sync, if a face changes, or if new faces are added. To
|
|
|
579 ;; get the lists back in sync, you can set the variable
|
|
|
580 ;; `ps-build-face-reference' to t, and the lists will be rebuilt the

581 ;; next time ps-print is invoked.
