  36 <p>This specification describes the attributes and extensions
  37 that CUPS adds to <a
  38 href="http://partners.adobe.com/public/developer/en/ps/5003.PPD_Spec_v4.3.pdf">
  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:

 272
 273 <p class='summary'>*cupsIPPReason reason/Reason Text: "optional URIs"</p>
 274
 275 <p>This optional attribute maps custom
 276 <code>printer-state-reasons</code> keywords that are generated by
 277 the driver to human readable text. The optional URIs string
 278 contains zero or more URIs separated by a newline. Each URI can
 279 be a CUPS server absolute path to a help file under the
 280 scheduler's <code>DocumentRoot</code> directory, a full HTTP URL
 281 ("http://www.domain.com/path/to/help/page.html"), or any other
 282 valid URI which directs the user at additional information
 283 concerning the condition that is being reported.</p>
 284
 285 <p>Examples:</p>

 301 http://www.vendor.com/help"
 302 *End
 303 </pre>
 304
 305 <h3>cupsLanguages</h3>
 306
 307 <p class='summary'>*cupsLanguages: "locale list"</p>
 308
 309 <p>This attribute describes which language localizations are
 310 included in the PPD. The "locale list" string is a space-delimited
 311 list of locale names ("en", "en_US", "fr_CA", etc.)</p>
 312
 313 <p>Example:</p>
 314
 315 <pre class='command'>
 316 <em>*% Specify Canadian, UK, and US English, and Candian and French French</em>
 317 *cupsLanguages: "en_CA en_UK en_US fr_CA fr_CA"
 318 </pre>
 319
 320 <h3>cupsManualCopies</h3>
 321
 322 <p class='summary'>*cupsManualCopies: boolean</p>
 323
 324 <p>This boolean attribute notifies the RIP filters that the
 325 destination printer does not support copy generation in
 326 hardware. The default value is <code>false</code>.</p>
 327
 328 <p>Example:</p>
 329
 330 <pre class='command'>
 331 <em>*% Tell the RIP filters to generate the copies for us</em>
 332 *cupsManualCopies: true
 333 </pre>
 334
 335 <h3>cupsModelNumber</h3>
 336
 337 <p class='summary'>*cupsModelNumber: number</p>
 338
 339 <p>This integer attribute specifies a printer-specific model
 340 number. This number can be used by a filter program to adjust
 341 the output for a specific model of printer.</p>
 342
 343 <p>Example:</p>
 344
 345 <pre class='command'>
 346 <em>*% Specify an integer for a driver-specific model number</em>
 347 *cupsModelNumber: 1234
 348 </pre>
 349
 350
 351 <h3>cupsPJLCharset</h3>
 352
 353 <p class='summary'>*cupsPJLCharset: "ISO character set name"</p>
 354
 355 <p>This string attribute specifies the character set that is used
 356 for strings in PJL commands. If not specified, US-ASCII is
 357 assumed.</p>
 358
 359 <p>Example:</p>
 360
 361 <pre class='command'>
 362 <em>*% Specify UTF-8 is used in PJL strings</em>
 363 *cupsPJLCharset: "UTF-8"
 364 </pre>
 365
 366
 367 <h3>cupsPortMonitor</h3>
 368
 369 <p class='summary'>*cupsPortMonitor urischeme/Descriptive Text: "port monitor"</p>
 370
 371 <p>This string attribute specifies printer-specific "port
 372 monitor" filters that may be used with the printer. The CUPS
 373 scheduler also looks for the <tt>Protocols</tt> attribute to see
 374 if the <tt>BCP</tt> or <tt>TBCP</tt> protocols are supported. If
 375 so, the corresponding port monitor ("bcp" and "tbcp",
 376 respectively) is listed in the printer's
 377 <tt>port-monitor-supported</tt> attribute.</p>
 378
 379 <p>The "urischeme" portion of the attribute specifies the URI scheme
 380 that this port monitor should be used for. Typically this is used to
 381 pre-select a particular port monitor for each type of connection that
 382 is supported by the printer. The "port monitor" string can be "none"
 383 to disable the port monitor for the given URI scheme.</p>
 384
 385 <p>Examples:</p>
 386
 387 <pre class='command'>
 388 <em>*% Specify a PostScript printer that supports the TBCP protocol</em>
 389 *Protocols: TBCP PJL
 390
 391 <em>*% Specify that TBCP should be used for socket connections but not USB</em>
 392 *cupsPortMonitor socket/AppSocket Printing: "tbcp"
 393 *cupsPortMonitor usb/USB Printing: "none"
 394
 395 <em>*% Specify a printer-specific port monitor for an Epson USB printer</em>
 396 *cupsPortMonitor usb/USB Status Monitor: "epson-usb"
 397 </pre>
 398
 399 <h3>cupsPreFilter</h3>
 400
 401 <p class='summary'>*cupsPreFilter: "source/type cost program"</p>
 402
 403 <p>This string attribute provides a pre-filter rule. The pre-filter
 404 program will be inserted in the conversion chain immediately
 405 before the filter that accepts the given MIME type.</p>
 406
 407 <p>Examples:</p>
 408
 409 <pre class='command'>
 410 <em>*% PDF pre-filter</em>
 411 *cupsPreFilter: "application/pdf 100 mypdfprefilter"
 412
 413 <em>*% PNG pre-filter</em>
 414 *cupsPreFilter: "image/png 0 mypngprefilter"
 415 </pre>
 416
 417 <h3>cupsVersion</h3>
 418
 419 <p class='summary'>*cupsVersion: major.minor</p>
 420
 421 <p>This required attribute describes which version of the CUPS
 422 PPD file extensions was used. Currently it must be the string
 423 "1.0", "1.1", or "1.2".</p>
 424
 425 <p>Example:</p>
 426
 427 <pre class='command'>
 428 <em>*% Specify a CUPS 1.2 driver</em>
 429 *cupsVersion: "1.2"
 430 </pre>
 431
 432 <h2 class='title'><a name='OPTIONS'>Custom Options</a></h2>
 433
 434 <p>CUPS supports custom options using an extension of the
 435 <tt>CustomPageSize</tt> and <tt>ParamCustomPageSize</tt>
 436 syntax:</p>
 437
 438 <pre class='command'>
 439 *CustomFoo True: "command"
 440 *ParamCustomFoo Name1/Text 1: order type minimum maximum
 441 *ParamCustomFoo Name2/Text 2: order type minimum maximum
 442 ...
 443 *ParamCustomFoo NameN/Text N: order type minimum maximum
 444 </pre>
 445
 446 <p>When the base option is part of the <tt>JCLSetup</tt> section,
 447 the "command" string contains JCL commands with "\order"
 448 placeholders for each numbered parameter. The CUPS API handles
 449 any necessary value quoting for HP-PJL commands. For example, if
 450 the JCL command string is "@PJL SET PASSCODE=\1" and the first
 451 option value is "1234" then CUPS will output the string
 452 "@PJL SET PASSCODE=1234".</p>
 453
 454 <p>For non-<tt>JCLSetup</tt> options, the "order" value is a
 455 number from 1 to N and specifies the order of values as they are
 456 placed on the stack before the command. For example, if the
 457 PostScript command string is
 458 "&lt;&lt;/cupsReal1 2 1 roll&gt;&gt;setpagedevice" and the
 459 option value is "2.0" then CUPS will output the string
 460 "2.0 &lt;&lt;/cupsReal1 2 1 roll&gt;&gt;setpagedevice".</p>
 461
 462 <p>The "type" is one of the following keywords:</p>
 463
 464 <ul>
 465
 466         <li><tt>curve</tt> - a real value from "minimum" to
 467         "maximum" representing a gamma correction curve using the
 468         function: f(x) = x <sup>value</sup></li>
 469
 470         <li><tt>int</tt> - an integer value from "minimum" to
 471         "maximum"</li>
 472
 473         <li><tt>invcurve</tt> - a real value from "minimum" to
 474         "maximum" representing a gamma correction curve using the
 475         function: f(x) = x <sup>1 / value</sup></li>
 476
 477         <li><tt>passcode</tt> - a string of numbers value with a
 478         minimum of "minimum" numbers and a maximum of "maximum"
 479         numbers ("minimum" and "maximum" are numbers and passcode
 480         strings are not displayed in the user interface)</li>
 481
 482         <li><tt>password</tt> - a string value with a minimum of
 483         "minimum" characters and a maximum of "maximum"
 484         characters ("minimum" and "maximum" are numbers and password
 485         strings are not displayed in the user interface)</li>
 486
 487         <li><tt>points</tt> - a measurement value in points from
 488         "minimum" to "maximum"</li>
 489
 490         <li><tt>real</tt> - a real value from "minimum" to
 491         "maximum"</li>
 492
 493         <li><tt>string</tt> - a string value with a minimum of
 494         "minimum" characters and a maximum of "maximum"
 495         characters ("minimum" and "maximum" are numbers)</li>
 496

 548 <p>CUPS supports two types of color profiles. The first type is
 549 based on sRGB and is used by the standard CUPS raster filters and
 550 ESP Ghostscript. The second type is based on ICC profiles and is
 551 used by the Core Graphics-based filters on MacOS X.</p>
 552
 553 <blockquote><b>Note:</b> At this time, none of the CUPS raster
 554 filters support ICC profiles. This will be addressed as time

 754 <h2 class='title'><a name='RASTERPS'>Writing PostScript Option Commands for Raster Drivers</a></h2>
 755
 756 <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>
 757
 758 <pre class='command'>
 759 *PageSize A4: "&lt;&lt;/PageSize[595 842]&gt;&gt;setpagedevice"
 760 </pre>
 761
 762 <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>
 763
 764 <pre class='command'>
 765 *CustomWatermarkText True: "&lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice"
 766 </pre>
 767
 768 <p>For a custom string value of "My Watermark", CUPS will produce the following PostScript code for the option:</p>
 769
 770 <pre class='command'>
 771 (My Watermark)
 772 &lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice
 773 </pre>
 774
 775 <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>
 776
 777 <pre class='command'>
 778 &lt;&lt;/cupsString1(My Watermark)&gt;&gt;setpagedevice
 779 </pre>
 780
 781 <p>The resulting dictionary sets the page device attributes that are sent to your raster driver in the page header.</p>
 782
 783 <h3>Custom Page Size Code</h3>
 784
 785 <p>There are many possible implementations of the <tt>CustomPageSize</tt> code. For CUPS raster drivers, the following code is recommended:</p>
 786
 787 <pre class='command'>
 788 *ParamCustomPageSize Width:        1 points <i>min-width max-width</i>
 789 *ParamCustomPageSize Height:       2 points <i>min-height max-height</i>
 790 *ParamCustomPageSize WidthOffset:  3 points 0 0
 791 *ParamCustomPageSize HeightOffset: 4 points 0 0
 792 *ParamCustomPageSize Orientation:  5 int 0 0
 793 *CustomPageSize True: "pop pop pop &lt;&lt;/PageSize[5 -2 roll]/ImagingBBox null&gt;&gt;setpagedevice"
 794 </pre>
 795
 796 <h3>Supported PostScript Operators</h3>
 797
 798 <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>
 799
 800 <ul>
 801
 802         <li><tt>&lt;&lt;</tt> - Start a dictionary.</li>
 803
 804         <li><tt>&gt;&gt;</tt> - End a dictionary.</li>
 805
 806         <li><tt>[</tt> - Start an array.</li>
 807
 808         <li><tt>]</tt> - End an array.</li>
 809
 810         <li><tt>copy</tt> - Copy the top N objects on the stack.</li>
 811
 812         <li><tt>dup</tt> - Copy the top object on the stack.</li>
 813
 814         <li><tt>index</tt> - Copy the Nth from the top object on the stack.</li>
 815
 816         <li><tt>pop</tt> - Pop the top object on the stack.</li>
 817
 818         <li><tt>roll</tt> - Shift the top N objects on the stack.</li>
 819
 820         <li><tt>setpagedevice</tt> - Set the page header values according to the key/value dictionary on the stack.</li>
 821
 822 </ul>
 823
 824 <blockquote><b>Note:</b> <em>Never<em> use the unsupported <tt>dict</tt> or <tt>put</tt> operators in your option code. These operators are typically used in option code dating back to Level 1 PostScript printers, which did not support the simpler <tt>&lt;&lt;</tt> or <tt>&gt;&gt;</tt> operators. If you have old option code using <tt>dict</tt> or <tt>put</tt>, you can rewrite it very easily to use the newer <tt>&lt;&lt;</tt> and <tt>&gt;&gt;</tt> operators instead. For example, the following code to set the page size:
 825
 826 <style type='text/css'><!--
 827 PRE B {
 828   background: #000000;
 829   color: #ffffff;
 830   padding: 2px 5px;
 831 }
 832 --></style>
 833
 834 <pre class='command'>
 835 <b>1 dict dup</b> /PageSize [612 792] <b>put</b> setpagedevice
 836 </pre>
 837
 838 <p>can be rewritten as:</p>
 839
 840 <pre class='command'>
 841 <b>&lt;&lt;</b> /PageSize [612 792] <b>&gt;&gt;</b> setpagedevice
 842 </pre>
