40 ;; About ps-print
|
|
|
41 ;; --------------
|
|
|
42 ;; This package provides printing of Emacs buffers on PostScript
|
|
|
43 ;; printers; the buffer's bold and italic text attributes are
|
|
|
44 ;; preserved in the printer output. Ps-print is intended for use with
|
|
|
45 ;; Emacs 19 or Lucid Emacs, together with a fontifying package such as
|
|
|
46 ;; font-lock or hilit.
|
|
|
47 ;;
|
|
|
48 ;; Using ps-print
|
|
|
49 ;; --------------
|
|
|
50 ;;
|
|
|
51 ;; The Commands
|
|
|
52 ;;
|
|
|
53 ;; Ps-print provides eight commands for generating PostScript images
|
|
|
54 ;; of Emacs buffers:
|
|
|
55 ;;
|
|
|
56 ;; ps-print-buffer
|
|
|
57 ;; ps-print-buffer-with-faces
|
|
|
58 ;; ps-print-region
|
|
|
59 ;; ps-print-region-with-faces
|
|
|
60 ;; ps-spool-buffer
|
|
|
61 ;; ps-spool-buffer-with-faces
|
|
|
62 ;; ps-spool-region
|
|
|
63 ;; ps-spool-region-with-faces
|
|
|
64 ;;
|
|
|
65 ;; These commands all perform essentially the same function: they
|
|
|
66 ;; generate PostScript images suitable for printing on a PostScript
|
|
|
67 ;; printer or displaying with GhostScript. These commands are
|
|
|
68 ;; collectively referred to as "ps-print- commands".
|
|
|
69 ;;
|
|
|
70 ;; The word "print" or "spool" in the command name determines when the
|
|
|
71 ;; PostScript image is sent to the printer:
|
|
|
72 ;;
|
|
|
73 ;; print - The PostScript image is immediately sent to the
|
|
|
74 ;; printer;
|
|
|
75 ;;
|
|
|
76 ;; spool - The PostScript image is saved temporarily in an
|
|
|
77 ;; Emacs buffer. Many images may be spooled locally
|
|
|
78 ;; before printing them. To send the spooled images
|
|
|
79 ;; to the printer, use the command ps-despool.
|
|
|
80 ;;
|
|
|
81 ;; The spooling mechanism was designed for printing lots of small
|
|
|
82 ;; files (mail messages or netnews articles) to save paper that would
|
|
|
83 ;; otherwise be wasted on banner pages, and to make it easier to find
|
|
|
84 ;; your output at the printer (it's easier to pick up one 50-page
|
|
|
85 ;; printout than to find 50 single-page printouts).
|
|
|
86 ;;
|
|
|
87 ;; Ps-print has a hook in the kill-emacs-hooks so that you won't
|
|
|
88 ;; accidently quit from Emacs while you have unprinted PostScript
|
|
|
89 ;; waiting in the spool buffer. If you do attempt to exit with
|
|
|
90 ;; spooled PostScript, you'll be asked if you want to print it, and if
|
|
|
91 ;; you decline, you'll be asked to confirm the exit; this is modeled
|
|
|
92 ;; on the confirmation that Emacs uses for modified buffers.
|
|
|
93 ;;
|
|
|
94 ;; The word "buffer" or "region" in the command name determines how
|
|
|
95 ;; much of the buffer is printed:
|
|
|
96 ;;
|
|
|
97 ;; buffer - Print the entire buffer.
|
|
|
98 ;;
|
|
|
99 ;; region - Print just the current region.
|
|
|
100 ;;
|
|
|
101 ;; The -with-faces suffix on the command name means that the command
|
|
|
102 ;; will include font, color, and underline information in the
|
|
|
103 ;; PostScript image, so the printed image can look as pretty as the
|
|
|
104 ;; buffer. The ps-print- commands without the -with-faces suffix
|
|
|
105 ;; don't include font, color, or underline information; images printed
|
|
|
106 ;; with these commands aren't as pretty, but are faster to generate.
|
|
|
107 ;;
|
|
|
108 ;; Two ps-print- command examples:
|
|
|
109 ;;
|
|
|
110 ;; ps-print-buffer - print the entire buffer,
|
|
|
111 ;; without font, color, or
|
|
|
112 ;; underline information, and
|
|
|
113 ;; send it immediately to the
|
|
|
114 ;; printer.
|
|
|
115 ;;
|
|
|
116 ;; ps-spool-region-with-faces - print just the current region;
|
|
|
117 ;; include font, color, and
|
|
|
118 ;; underline information, and
|
|
|
119 ;; spool the image in Emacs to
|
|
|
120 ;; send to the printer later.
|
|
|
121 ;;
|
|
|
122 ;;
|
|
|
123 ;; Invoking Ps-Print
|
|
|
124 ;;
|
|
|
125 ;; To print your buffer, type
|
|
|
126 ;;
|
|
|
127 ;; M-x ps-print-buffer
|
|
|
128 ;;
|
|
|
129 ;; or substitute one of the other seven ps-print- commands. The
|
|
|
130 ;; command will generate the PostScript image and print or spool it as
|
|
|
131 ;; specified. By giving the command a prefix argument
|
|
|
132 ;;
|
|
|
133 ;; C-u M-x ps-print-buffer
|
|
|
134 ;;
|
|
|
135 ;; it will save the PostScript image to a file instead of sending it
|
|
|
136 ;; to the printer; you will be prompted for the name of the file to
|
|
|
137 ;; save the image to. The prefix argument is ignored by the commands
|
|
|
138 ;; that spool their images, but you may save the spooled images to a
|
|
|
139 ;; file by giving a prefix argument to ps-despool:
|
|
|
140 ;;
|
|
|
141 ;; C-u M-x ps-despool
|
|
|
142 ;;
|
|
|
143 ;; When invoked this way, ps-despool will prompt you for the name of
|
|
|
144 ;; the file to save to.
|
|
|
145 ;;
|
|
|
146 ;; Any of the ps-print- commands can be bound to keys; I recommend
|
|
|
147 ;; binding ps-spool-buffer-with-faces, ps-spool-region-with-faces, and
|
|
|
148 ;; ps-despool. Here are the bindings I use on my Sun 4 keyboard:
|
|
|
149 ;;
|
|
|
150 ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
|
|
|
151 ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
|
|
|
152 ;; (global-set-key '(control f22) 'ps-despool)
|
|
|
153 ;;
|
|
|
154 ;;
|
|
|
155 ;; The Printer Interface
|
|
|
156 ;;
|
|
|
157 ;; The variables ps-lpr-command and ps-lpr-switches determine what
|
|
|
158 ;; command is used to send the PostScript images to the printer, and
|
|
|
159 ;; what arguments to give the command. These are analogous to lpr-
|
|
|
160 ;; command and lpr-switches.
|
|
|
161 ;;
|
|
|
162 ;; NOTE: ps-lpr-command and ps-lpr-switches take their initial values
|
|
|
163 ;; from the variables lpr-command and lpr-switches. If you have
|
|
|
164 ;; lpr-command set to invoke a pretty-printer such as enscript,
|
|
|
165 ;; then ps-print won't work properly. ps-lpr-command must name
|
|
|
166 ;; a program that does not format the files it prints.
|
|
|

|
|
|
169 ;; How Ps-Print Deals With Fonts
|
|
|
170 ;;
|
|
|
171 ;; The ps-print-*-with-faces commands attempt to determine which faces
|
|
|
172 ;; should be printed in bold or italic, but their guesses aren't
|
|
|
173 ;; always right. For example, you might want to map colors into faces
|
|
|
174 ;; so that blue faces print in bold, and red faces in italic.
|
|
|
175 ;;
|
|
|
176 ;; It is possible to force ps-print to consider specific faces bold or
|
|
|
177 ;; italic, no matter what font they are displayed in, by setting the
|
|
|
178 ;; variables ps-bold-faces and ps-italic-faces. These variables
|
|
|
179 ;; contain lists of faces that ps-print should consider bold or
|
|
|
180 ;; italic; to set them, put code like the following into your .emacs
|
|
|
181 ;; file:
|
|
|
182 ;;
|
|
|
183 ;; (setq ps-bold-faces '(my-blue-face))
|
|
|
184 ;; (setq ps-italic-faces '(my-red-face))
|
|
|
185 ;;
|
|
|
186 ;; Faces like bold-italic that are both bold and italic should go in
|
|
|
187 ;; *both* lists.
|
|
|
188 ;;
|
|
|
189 ;; Ps-print does not attempt to guess the sizes of fonts; all text is
|
|
|
190 ;; rendered using the Courier font family, in 10 point size. To
|
|
|
191 ;; change the font family, change the variables ps-font, ps-font-bold,
|
|
|
192 ;; ps-font-italic, and ps-font-bold-italic; fixed-pitch fonts work
|
|
|
193 ;; best, but are not required. To change the font size, change the
|
|
|
194 ;; variable ps-font-size.
|
|
|
195 ;;
|
|
|
196 ;; If you change the font family or size, you MUST also change the
|
|
|
197 ;; variables ps-line-height, ps-avg-char-width, and ps-space-width, or
|
|
|
198 ;; ps-print cannot correctly place line and page breaks.
|
|
|
199 ;;
|
|
|
200 ;; Ps-print keeps internal lists of which fonts are bold and which are
|
|
|
201 ;; italic; these lists are built the first time you invoke ps-print.
|
|
|
202 ;; For the sake of efficiency, the lists are built only once; the same
|
|
|
203 ;; lists are referred in later invokations of ps-print.
|
|
|
204 ;;
|
|
|
205 ;; Because these lists are built only once, it's possible for them to
|
|
|
206 ;; get out of sync, if a face changes, or if new faces are added. To
|
|
|
207 ;; get the lists back in sync, you can set the variable
|
|
|
208 ;; ps-build-face-reference to t, and the lists will be rebuilt the
|
|
|
209 ;; next time ps-print is invoked.
|
|
|
210 ;;
|
|
|
211 ;;
|
|
|
212 ;; How Ps-Print Deals With Color
|
|
|
213 ;;
|
|
|
214 ;; Ps-print detects faces with foreground and background colors
|
|
|
215 ;; defined and embeds color information in the PostScript image. The
|
|
|
216 ;; default foreground and background colors are defined by the
|
|
|
217 ;; variables ps-default-fg and ps-default-bg. On black-and-white
|
|
|
218 ;; printers, colors are displayed in grayscale. To turn off color
|
|
|
219 ;; output, set ps-print-color-p to nil.
|
|
|
220 ;;
|
|
|
221 ;;
|
|
|
222 ;; Headers
|
|
|
223 ;;
|
|
|
224 ;; Ps-print can print headers at the top of each page; the default
|
|
|
225 ;; headers contain the following four items: on the left, the name of
|
|
|
226 ;; the buffer and, if the buffer is visiting a file, the file's
|
|
|
227 ;; directory; on the right, the page number and date of printing. The
|
|
|
228 ;; default headers look something like this:
|
|
|
229 ;;
|
|
|
230 ;; ps-print.el 1/21
|
|
|
231 ;; /home/jct/emacs-lisp/ps/new 94/12/31
|
|
|
232 ;;
|
|
|
233 ;; When printing on duplex printers, left and right are reversed so
|
|
|
234 ;; that the page numbers are toward the outside.
|
|
|
235 ;;
|
|
|
236 ;; Headers are configurable. To turn them off completely, set
|
|
|
237 ;; ps-print-header to nil. To turn off the header's gaudy framing
|
|
|
238 ;; box, set ps-print-header-frame to nil. Page numbers are printed in
|
|
|
239 ;; "n/m" format, indicating page n of m pages; to omit the total page
|
|
|
240 ;; count and just print the page number, set ps-show-n-of-n to nil.
|
|
|
241 ;;
|
|
|
242 ;; The amount of information in the header can be changed by changing
|
|
|
243 ;; the number of lines. To show less, set ps-header-lines to 1, and
|
|
|
244 ;; the header will show only the buffer name and page number. To show
|
|
|
245 ;; more, set ps-header-lines to 3, and the header will show the time of
|
|
|
246 ;; printing below the date.
|
|
|
247 ;;
|
|
|
248 ;; To change the content of the headers, change the variables
|
|
|
249 ;; ps-left-header and ps-right-header. These variables are lists,
|
|
|
250 ;; specifying top-to-bottom the text to display on the left or right
|
|
|
251 ;; side of the header. Each element of the list should be a string or
|
|
|
252 ;; a symbol. Strings are inserted directly into the PostScript
|
|
|
253 ;; arrays, and should contain the PostScript string delimiters '(' and
|
|
|
254 ;; ')'.
|
|
|
255 ;;
|
|
|
256 ;; Symbols in the header format lists can either represent functions
|
|
|
257 ;; or variables. Functions are called, and should return a string to
|
|
|
258 ;; show in the header. Variables should contain strings to display in
|
|
|
259 ;; the header. In either case, function or variable, the PostScript
|
|
|
260 ;; strings delimeters are added by ps-print, and should not be part of
|
|
|
261 ;; the returned value.
|
|
|
262 ;;
|
|
|
263 ;; Here's an example: say we want the left header to display the text
|
|
|
264 ;;
|
|
|
265 ;; Moe
|
|
|
266 ;; Larry
|
|
|
267 ;; Curly
|
|
|
268 ;;
|
|
|
269 ;; where we have a function to return "Moe"
|
|
|
270 ;;
|
|
|
271 ;; (defun moe-func ()
|
|
|
272 ;; "Moe")
|
|
|
273 ;;
|
|
|
274 ;; a variable specifying "Larry"
|
|
|
275 ;;
|
|
|
276 ;; (setq larry-var "Larry")
|
|
|
277 ;;
|
|
|
278 ;; and a literal for "Curly". Here's how ps-left-header should be
|
|
|
279 ;; set:
|
|
|
280 ;;
|
|
|
281 ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
|
|
|
282 ;;
|
|
|
283 ;; Note that Curly has the PostScript string delimiters inside his
|
|
|
284 ;; quotes -- those aren't misplaced lisp delimiters! Without them,
|
|
|
285 ;; PostScript would attempt to call the undefined function Curly,
|
|
|
286 ;; which would result in a PostScript error. Since most printers
|
|
|
287 ;; don't report PostScript errors except by aborting the print job,
|
|
|
288 ;; this kind of error can be hard to track down. Consider yourself
|
|
|
289 ;; warned.
|
|
|
290 ;;
|
|
|
291 ;;
|
|
|
292 ;; Duplex Printers
|
|
|
293 ;;
|
|
|
294 ;; If you have a duplex-capable printer (one that prints both sides of
|
|
|
295 ;; the paper), set ps-spool-duplex to t. Ps-print will insert blank
|
|
|
296 ;; pages to make sure each buffer starts on the correct side of the
|
|
|
297 ;; paper. Don't forget to set ps-lpr-switches to select duplex
|
|
|
298 ;; printing for your printer.
|
|
|
299 ;;
|
|
|
300 ;;
|
|
|
301 ;; Paper Size
|
|
|
302 ;;
|
|
|
303 ;; The variable ps-paper-type determines the size of paper ps-print
|
|
|
304 ;; formats for; it should contain one of the symbols ps-letter,
|
|
|
305 ;; ps-legal, or ps-a4. The default is ps-letter.
|
|
|
306 ;;
|
|

307 ;;
|
|
|
308 ;; Installing ps-print
|
|
|
309 ;; -------------------
|
|
|
310 ;;
|
|
|
311 ;; 1. Place ps-print.el somewhere in your load-path and byte-compile
|
|
|
312 ;; it. You can ignore all byte-compiler warnings; they are the
|
|
|
313 ;; result of multi-Emacs support. This step is necessary only if
|
|
|
314 ;; you're installing your own ps-print; if ps-print came with your
|
|
|
315 ;; copy of Emacs, this been done already.
|
|
|
316 ;;
|
|
|
317 ;; 2. Place in your .emacs file the line
|
|
|
318 ;;
|
|
|
319 ;; (require 'ps-print)
|
|
|
320 ;;
|
|
|
321 ;; to load ps-print. Or you may cause any of the ps-print commands
|
|
|
322 ;; to be autoloaded with an autoload command such as:
|
|
|
323 ;;
|
|
|
324 ;; (autoload 'ps-print-buffer "ps-print"
|
|
|
325 ;; "Generate and print a PostScript image of the buffer..." t)
|
|
|
326 ;;
|
|
|
327 ;; 3. Make sure that the variables ps-lpr-command and ps-lpr-switches
|
|
|
328 ;; contain appropriate values for your system; see the usage notes
|
|
|
329 ;; below and the documentation of these variables.

346 ;; Known bugs and limitations of ps-print:
|
|
|
347 ;; --------------------------------------
|
|
|
348 ;; Although color printing will work in XEmacs 19.12, it doesn't work
|
|
|
349 ;; well; in particular, bold or italic fonts don't print in the right
|
|
|
350 ;; background color.
|
|
|
351 ;;
|
|
|
352 ;; Invisible properties aren't correctly ignored in XEmacs 19.12.
|
|
|
353 ;;
|
|
|
354 ;; Automatic font-attribute detection doesn't work well, especially
|
|
|
355 ;; with hilit19 and older versions of get-create-face. Users having
|
|
|
356 ;; problems with auto-font detection should use the lists ps-italic-
|
|
|
357 ;; faces and ps-bold-faces and/or turn off automatic detection by
|
|
|
358 ;; setting ps-auto-font-detect to nil.
|
|
|
359 ;;
|
|
|
360 ;; Automatic font-attribute detection doesn't work with XEmacs 19.12
|
|
|
361 ;; in tty mode; use the lists ps-italic-faces and ps-bold-faces
|
|
|
362 ;; instead.
|
|
|
363 ;;
|
|
|
364 ;; Still too slow; could use some hand-optimization.
|
|
|
365 ;;
|
|
|
366 ;; ASCII Control characters other than tab, linefeed and pagefeed are
|
|
|
367 ;; not handled.
|

|
368 ;;
|
|

369 ;; Default background color isn't working.
|

370 ;;
|

371 ;; Faces are always treated as opaque.
