ef416fc2 | 39 | Adobe TechNote #5003: PostScript Printer Description File Format |
40 | Specification Version 4.3</a>. PostScript Printer Description | |
41 | ("PPD") files describe the capabilities of each printer and are | |
42 | used by CUPS to support printer-specific features and intelligent | |
43 | filtering.</p> | |
44 | ||
45 | <h2 class='title'><a name='SYNTAX'>PPD File Syntax</a></h2> | |
46 | ||
47 | <p>The PPD format is text-based and uses lines of up to 255 | |
48 | characters terminated by a carriage return, linefeed, or | |
49 | combination of carriage return and line feed. The following ABNF | |
50 | definition [RFC2234] defines the general format of lines in a PPD | |
51 | file:</p> | |
52 | ||
53 | <pre class='command'> | |
54 | PPD-FILE = HEADER +(DATA / COMMENT / LINE-END) | |
55 | ||
56 | HEADER = "*" 0x50.50.44.2D.41.64.6F.62.65 ":" ; *PPD-Adobe: | |
57 | *WSP DQUOTE "4.3" DQUOTE LINE-END | |
58 | ||

60 | ||
61 | DATA = "*" 1*KCHAR [ WSP 1*KCHAR [ "/" 1*TCHAR ] ] ":" | |
62 | 1*(*WSP VALUE) LINE-END | |
63 | ||
64 | VALUE = 1*TCHAR / DQUOTE 1*SCHAR DQUOTE | |
65 | ||
66 | KCHAR = ALPHA / DIGIT / "_" / "." / "-" | |

168 | ||
169 | <p class='summary'>*cupsIPPReason reason/Reason Text: "optional URIs"</p> | |
170 | ||
171 | <p>This optional attribute maps custom | |
172 | <code>printer-state-reasons</code> keywords that are generated by | |
173 | the driver to human readable text. The optional URIs string | |
174 | contains zero or more URIs separated by a newline. Each URI can | |
175 | be a CUPS server absolute path to a help file under the | |
176 | scheduler's <code>DocumentRoot</code> directory, a full HTTP URL | |
177 | ("http://www.domain.com/path/to/help/page.html"), or any other | |
178 | valid URI which directs the user at additional information | |
179 | concerning the condition that is being reported.</p> | |

202 | ||
203 | <p class='summary'>*cupsLanguages: "locale list"</p> | |
204 | ||
205 | <p>This attribute describes which language localizations are | |
206 | included in the PPD. The "locale list" string is a space-delimited | |
b94498cf | 207 | list of locale names ("en", "en_US", "fr_CA", etc.)</p> |
a4d04587 | 208 | |
209 | <p>Example:</p> | |

ef416fc2 | 216 | <h3>cupsManualCopies</h3> |
217 | ||
a4d04587 | 218 | <p class='summary'>*cupsManualCopies: boolean</p> |
219 | ||
ef416fc2 | 220 | <p>This boolean attribute notifies the RIP filters that the |
221 | destination printer does not support copy generation in | |
a4d04587 | 222 | hardware. The default value is <code>false</code>.</p> |
ef416fc2 | 223 | |
224 | <p>Example:</p> | |
225 | ||
226 | <pre class='command'> | |
227 | <em>*% Tell the RIP filters to generate the copies for us</em> | |
228 | *cupsManualCopies: true | |
229 | </pre> | |
230 | ||
231 | <h3>cupsModelNumber</h3> | |
232 | ||
a4d04587 | 233 | <p class='summary'>*cupsModelNumber: number</p> |
234 | ||
ef416fc2 | 235 | <p>This integer attribute specifies a printer-specific model |
236 | number. This number can be used by a filter program to adjust | |
237 | the output for a specific model of printer.</p> | |
238 | ||
239 | <p>Example:</p> | |
240 | ||
241 | <pre class='command'> | |
242 | <em>*% Specify an integer for a driver-specific model number</em> | |
243 | *cupsModelNumber: 1234 | |
244 | </pre> | |

247 | <h3>cupsPJLCharset</h3> | |
248 | ||
249 | <p class='summary'>*cupsPJLCharset: "ISO character set name"</p> | |
250 | ||
251 | <p>This string attribute specifies the character set that is used | |
252 | for strings in PJL commands. If not specified, US-ASCII is | |
253 | assumed.</p> | |
254 | ||
255 | <p>Example:</p> | |
256 | ||
257 | <pre class='command'> | |
258 | <em>*% Specify UTF-8 is used in PJL strings</em> | |
259 | *cupsPJLCharset: "UTF-8" | |
260 | </pre> | |
261 | ||
262 | ||
ef416fc2 | 263 | <h3>cupsPortMonitor</h3> |
264 | ||
a4d04587 | 265 | <p class='summary'>*cupsPortMonitor urischeme/Descriptive Text: "port monitor"</p> |
266 | ||
ef416fc2 | 267 | <p>This string attribute specifies printer-specific "port |
268 | monitor" filters that may be used with the printer. The CUPS | |
269 | scheduler also looks for the <tt>Protocols</tt> attribute to see | |
270 | if the <tt>BCP</tt> or <tt>TBCP</tt> protocols are supported. If | |
271 | so, the corresponding port monitor ("bcp" and "tbcp", | |
272 | respectively) is listed in the printer's | |
273 | <tt>port-monitor-supported</tt> attribute.</p> | |
274 | ||
a4d04587 | 275 | <p>The "urischeme" portion of the attribute specifies the URI scheme |
276 | that this port monitor should be used for. Typically this is used to | |
277 | pre-select a particular port monitor for each type of connection that | |
278 | is supported by the printer. The "port monitor" string can be "none" | |
279 | to disable the port monitor for the given URI scheme.</p> | |
280 | ||
ef416fc2 | 281 | <p>Examples:</p> |
282 | ||
283 | <pre class='command'> | |
284 | <em>*% Specify a PostScript printer that supports the TBCP protocol</em> | |
285 | *Protocols: TBCP PJL | |
286 | ||
a4d04587 | 287 | <em>*% Specify that TBCP should be used for socket connections but not USB</em> |
288 | *cupsPortMonitor socket/AppSocket Printing: "tbcp" | |
289 | *cupsPortMonitor usb/USB Printing: "none" | |
290 | ||
ef416fc2 | 291 | <em>*% Specify a printer-specific port monitor for an Epson USB printer</em> |
a4d04587 | 292 | *cupsPortMonitor usb/USB Status Monitor: "epson-usb" |
ef416fc2 | 293 | </pre> |
294 | ||
f7deaa1a | 295 | <h3>cupsPreFilter</h3> |
296 | ||
297 | <p class='summary'>*cupsPreFilter: "source/type cost program"</p> | |
298 | ||
299 | <p>This string attribute provides a pre-filter rule. The pre-filter | |
300 | program will be inserted in the conversion chain immediately | |
301 | before the filter that accepts the given MIME type.</p> | |
302 | ||
303 | <p>Examples:</p> | |
304 | ||
305 | <pre class='command'> | |
306 | <em>*% PDF pre-filter</em> | |
307 | *cupsPreFilter: "application/pdf 100 mypdfprefilter" | |
308 | ||
309 | <em>*% PNG pre-filter</em> | |
310 | *cupsPreFilter: "image/png 0 mypngprefilter" | |
311 | </pre> | |
312 | ||
ef416fc2 | 313 | <h3>cupsVersion</h3> |
314 | ||
a4d04587 | 315 | <p class='summary'>*cupsVersion: major.minor</p> |
316 | ||
ef416fc2 | 317 | <p>This required attribute describes which version of the CUPS |
318 | PPD file extensions was used. Currently it must be the string | |
319 | "1.0", "1.1", or "1.2".</p> | |
320 | ||
321 | <p>Example:</p> | |
322 | ||
323 | <pre class='command'> | |
324 | <em>*% Specify a CUPS 1.2 driver</em> | |
325 | *cupsVersion: "1.2" | |
326 | </pre> | |
327 | ||
ef416fc2 | 328 | <h2 class='title'><a name='OPTIONS'>Custom Options</a></h2> |
329 | ||
330 | <p>CUPS supports custom options using an extension of the | |
331 | <tt>CustomPageSize</tt> and <tt>ParamCustomPageSize</tt> | |
332 | syntax:</p> | |
333 | ||
334 | <pre class='command'> | |
335 | *CustomFoo True: "command" | |
336 | *ParamCustomFoo Name1/Text 1: order type minimum maximum | |
337 | *ParamCustomFoo Name2/Text 2: order type minimum maximum | |
338 | ... | |
339 | *ParamCustomFoo NameN/Text N: order type minimum maximum | |
340 | </pre> | |
341 | ||
342 | <p>When the base option is part of the <tt>JCLSetup</tt> section, | |
343 | the "command" string contains JCL commands with "\order" | |
344 | placeholders for each numbered parameter. The CUPS API handles | |
a4d04587 | 345 | any necessary value quoting for HP-PJL commands. For example, if |
346 | the JCL command string is "@PJL SET PASSCODE=\1" and the first | |
347 | option value is "1234" then CUPS will output the string | |
348 | "@PJL SET PASSCODE=1234".</p> | |
ef416fc2 | 349 | |
350 | <p>For non-<tt>JCLSetup</tt> options, the "order" value is a | |
351 | number from 1 to N and specifies the order of values as they are | |
a4d04587 | 352 | placed on the stack before the command. For example, if the |
353 | PostScript command string is | |
354 | "<</cupsReal1 2 1 roll>>setpagedevice" and the | |
355 | option value is "2.0" then CUPS will output the string | |
356 | "2.0 <</cupsReal1 2 1 roll>>setpagedevice".</p> | |
ef416fc2 | 357 | |
358 | <p>The "type" is one of the following keywords:</p> | |
359 | ||
360 | <ul> | |
361 | ||
362 | <li><tt>curve</tt> - a real value from "minimum" to | |
363 | "maximum" representing a gamma correction curve using the | |
364 | function: f(x) = x <sup>value</sup></li> | |
365 | ||
366 | <li><tt>int</tt> - an integer value from "minimum" to | |
367 | "maximum"</li> | |
368 | ||
369 | <li><tt>invcurve</tt> - a real value from "minimum" to | |
370 | "maximum" representing a gamma correction curve using the | |
371 | function: f(x) = x <sup>1 / value</sup></li> | |
372 | ||
373 | <li><tt>passcode</tt> - a string of numbers value with a | |
374 | minimum of "minimum" numbers and a maximum of "maximum" | |
a4d04587 | 375 | numbers ("minimum" and "maximum" are numbers and passcode |
376 | strings are not displayed in the user interface)</li> | |
ef416fc2 | 377 | |
378 | <li><tt>password</tt> - a string value with a minimum of | |
379 | "minimum" characters and a maximum of "maximum" | |
a4d04587 | 380 | characters ("minimum" and "maximum" are numbers and password |
381 | strings are not displayed in the user interface)</li> | |
ef416fc2 | 382 | |
383 | <li><tt>points</tt> - a measurement value in points from | |
384 | "minimum" to "maximum"</li> | |
385 | ||
386 | <li><tt>real</tt> - a real value from "minimum" to | |
387 | "maximum"</li> | |
388 | ||
389 | <li><tt>string</tt> - a string value with a minimum of | |
390 | "minimum" characters and a maximum of "maximum" | |
a4d04587 | 391 | characters ("minimum" and "maximum" are numbers)</li> |
ef416fc2 | 392 | |

b86bc4cf | 650 | <h2 class='title'><a name='RASTERPS'>Writing PostScript Option Commands for Raster Drivers</a></h2> |
651 | ||
652 | <p>PPD files are used for both PostScript and non-PostScript printers. For CUPS raster drivers, you use a subset of the PostScript language to set page device attributes such as page size, resolution, and so forth. For example, the following code sets the page size to A4 size:</p> | |
653 | ||
654 | <pre class='command'> | |
655 | *PageSize A4: "<</PageSize[595 842]>>setpagedevice" | |
656 | </pre> | |
657 | ||
658 | <p>Custom options typically use other operators to organize the values into a key/value dictionary for <tt>setpagedevice</tt>. For example, our previous <tt>CustomWatermarkText</tt> option code uses the <tt>roll</tt> operator to move the custom string value into the dictionary for <tt>setpagedevice</tt>:</p> | |
659 | ||
660 | <pre class='command'> | |
661 | *CustomWatermarkText True: "<</cupsString1 3 -1 roll>>setpagedevice" | |
662 | </pre> | |
663 | ||
664 | <p>For a custom string value of "My Watermark", CUPS will produce the following PostScript code for the option:</p> | |
665 | ||
666 | <pre class='command'> | |
667 | (My Watermark) | |
668 | <</cupsString1 3 -1 roll>>setpagedevice | |
669 | </pre> | |
670 | ||
671 | <p>The code moves the string value ("My Watermark") from the bottom of the stack to the top, creating a dictionary that looks like:</p> | |
672 | ||
673 | <pre class='command'> | |
674 | <</cupsString1(My Watermark)>>setpagedevice | |
675 | </pre> | |
676 | ||
677 | <p>The resulting dictionary sets the page device attributes that are sent to your raster driver in the page header.</p> | |
678 | ||
679 | <h3>Supported PostScript Operators</h3> | |
680 | ||
681 | <p>CUPS supports the following PostScript operators in addition to the usual PostScript number, string (literal and hex-encoded), boolean, null, and name values:</p> | |
682 | ||
683 | <ul> | |
684 | ||
685 | <li><tt><<</tt> - Start a dictionary.</li> | |
686 | ||
687 | <li><tt>>></tt> - End a dictionary.</li> | |
688 | ||
689 | <li><tt>[</tt> - Start an array.</li> | |
690 | ||
691 | <li><tt>]</tt> - End an array.</li> | |
692 | ||
693 | <li><tt>copy</tt> - Copy the top N objects on the stack.</li> | |
694 | ||
695 | <li><tt>dup</tt> - Copy the top object on the stack.</li> | |
696 | ||
697 | <li><tt>index</tt> - Copy the Nth from the top object on the stack.</li> | |
698 | ||
699 | <li><tt>pop</tt> - Pop the top object on the stack.</li> | |
700 | ||
701 | <li><tt>roll</tt> - Shift the top N objects on the stack.</li> | |
702 | ||
703 | <li><tt>setpagedevice</tt> - Set the page header values according to the key/value dictionary on the stack.</li> | |
704 | ||
705 | </ul> | |
