 441
 442 <p>The PPD format is text-based and uses lines of up to 255 characters terminated by a carriage return, linefeed, or combination of carriage return and line feed. The following ABNF definition [<a href="http://tools.ietf.org/html/rfc5234" target="_blank">RFC5234</a>] defines the general format of lines in a PPD file:</p>
 443
 444 <pre class='command'>

 446
 447 HEADER   = "*PPD-Adobe:" *WSP DQUOTE VERSION DQUOTE LINE-END

 468 <h2 class='title'><a name='AUTOCONFIG'>Auto-Configuration</a></h2>
 469
 470 <p>CUPS supports several methods of auto-configuration via PPD keywords.</p>
 471
 472 <h3><span class='info'>Mac OS X 10.5</span><a name='APAutoSetupTool'>APAutoSetupTool</a></h3>
 473
 474 <p class='summary'>*APAutoSetupTool: "/LibraryPrinters/vendor/filename"</p>
 475
 476 <p>This Mac OS X keyword defines a program that sets the default option choices. It is run when a printer is added from the <var>Add Printer</var> window or the <var>Nearby Printers</var> list in the <var>Print</var> dialog.</p>
 477
 478 <p>The program is provided with two arguments: the printer's device URI and the PPD file to be used for the printer. The program must write an updated PPD file to stdout.</p>
 479
 480 <p>Examples:</p>
 481
 482 <pre class='command'>
 483 *% Use our setup tool when adding a printer
 484 *APAutoSetupTool: "/Library/Printers/vendor/Tools/autosetuptool"
 485 </pre>
 486
 487 <h3><span class='info'>Mac OS X 10.2/CUPS 1.4</span><a name='QUERYKEYWORD'>?MainKeyword</a></h3>
 488
 489 <p class='summary'>*?<i>MainKeyword</i>: "<br>
 490   PostScript query code that writes a message using the = operator...<br>
 491 "<br>
 492 *End</p>
 493
 494 <p>The <tt>?<i>MainKeyword</i></tt> keyword defines PostScript code that determines the currently selected/enabled option keyword (choice) for the main keyword (option). It is typically used when communicating with USB, serial, Appletalk, and AppSocket (port 9100) printers.</p>
 495
 496 <p>The PostScript code typically sends its response back using the <tt>=</tt> operator.</p>
 497
 498 <p>Example:</p>
 499
 500 <pre class='command'>
 501 *OpenUI OptionDuplex/Duplexer Installed: Boolean
 502 *DuplexOptionDuplex: False
 503 *OptionDuplex False/Not Installed: ""

 539 <p>CUPS supports three types of color profiles. The first type is based on sRGB and is used by the standard CUPS raster filters and GPL Ghostscript. The second type is based on ICC profiles and is used by the Quartz-based filters on MacOS X. The final type is based on well-known colorspaces such as sRGB and Adobe RGB.</p>
 540
 541 <blockquote><b>Note:</b>
 542
 543 <p>At this time, none of the CUPS raster filters support ICC profiles. This will be addressed as time and resources permit.</p>

 702 <h2 class='title'><a name='CONSTRAINTS'>Constraints</a></h2>
 703
 704 <p>Constraints are option choices that are not allowed by the driver or device, for example printing 2-sided transparencies. All versions of CUPS support constraints defined by the legacy Adobe <tt>UIConstraints</tt> and <tt>NonUIConstraints</tt> keywords which support conflicts between any two option choices, for example:</p>
 705
 706 <pre class='command'>
 707 *% Do not allow 2-sided printing on transparency media
 708 *UIConstraints: "*Duplex *MediaType Transparency"
 709 *UIConstraints: "*MediaType Transparency *Duplex"
 710 </pre>
 711
 712 <p>While nearly all constraints can be expressed using these keywords, there are valid scenarios requiring constraints between more than two option choices. In addition, resolution of constraints is problematic since users and software have to guess how a particular constraint is best resolved.</p>
 713
 714 <p>CUPS 1.4 and higher define two new keywords for constraints, <tt>cupsUIConstraints</tt> and <tt>cupsUIResolver</tt>. Each <tt>cupsUIConstraints</tt> keyword points to a <tt>cupsUIResolver</tt> keyword which specifies alternate options that resolve the conflict condition. The same <tt>cupsUIResolver</tt> can be used by multiple <tt>cupsUIConstraints</tt>.</p>
 715
 716 <blockquote><b>Note:</b>
 717
 718 <p>When developing PPD files that contain constraints, it is very important to use the <a href="man-cupstestppd.html">cupstestppd(1)</a> program to verify that your constraints are accurate and cannot result in unresolvable option selections.</p>

 865
 866 <p>When the base option is part of the <tt>JCLSetup</tt> section, the "command" string contains JCL commands with "\order" placeholders for each numbered parameter.

 868
 869 <p>For non-<tt>JCLSetup</tt> options, the "order" value is a number from 1 to N and specifies the order of values as they are placed on the stack before the command.

 940 <h2 class='title'><a name='RASTERPS'>Writing PostScript Option Commands for Raster Drivers</a></h2>
 941
 942 <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 keywords such as page size, resolution, and so forth. For example, the following code sets the page size to A4 size:</p>
 943
 944 <pre class='command'>
 945 *PageSize A4: "&lt;&lt;/PageSize[595 842]&gt;&gt;setpagedevice"
 946 </pre>
 947
 948 <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>
 949
 950 <pre class='command'>
 951 *CustomWatermarkText True: "&lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice"
 952 </pre>
 953
 954 <p>For a custom string value of "My Watermark", CUPS will produce the following PostScript code for the option:</p>
 955
 956 <pre class='command'>
 957 (My Watermark)
 958 &lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice
 959 </pre>
 960
 961 <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>
 962
 963 <pre class='command'>
 964 &lt;&lt;/cupsString1(My Watermark)&gt;&gt;setpagedevice
 965 </pre>
 966
 967 <p>The resulting dictionary sets the page device attributes that are sent to your raster driver in the page header.</p>
 968
 969 <h3>Custom Page Size Code</a></h3>
 970
 971 <p>There are many possible implementations of the <tt>CustomPageSize</tt> code. For CUPS raster drivers, the following code is recommended:</p>
 972
 973 <pre class='command'>
 974 *ParamCustomPageSize Width:        1 points <i>min-width max-width</i>
 975 *ParamCustomPageSize Height:       2 points <i>min-height max-height</i>
 976 *ParamCustomPageSize WidthOffset:  3 points 0 0
 977 *ParamCustomPageSize HeightOffset: 4 points 0 0
 978 *ParamCustomPageSize Orientation:  5 int 0 0
 979 *CustomPageSize True: "pop pop pop &lt;&lt;/PageSize[5 -2 roll]/ImagingBBox null&gt;&gt;setpagedevice"
 980 </pre>
 981
 982 <h3>Supported PostScript Operators</a></h3>
 983
 984 <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>
 985
 986 <ul>
 987
 988         <li><tt>&lt;&lt;</tt> - Start a dictionary.</li>
 989
 990         <li><tt>&gt;&gt;</tt> - End a dictionary.</li>
 991
 992         <li><tt>[</tt> - Start an array.</li>
 993
 994         <li><tt>]</tt> - End an array.</li>
 995
 996         <li><tt>copy</tt> - Copy the top N objects on the stack.</li>
 997
 998         <li><tt>dup</tt> - Copy the top object on the stack.</li>
 999
1000         <li><tt>index</tt> - Copy the Nth from the top object on the stack.</li>
1001
1002         <li><tt>pop</tt> - Pop the top object on the stack.</li>
1003
1004         <li><tt>roll</tt> - Shift the top N objects on the stack.</li>
1005
1006         <li><tt>setpagedevice</tt> - Set the page header values according to the key/value dictionary on the stack.</li>
1007
1008 </ul>
1009
1010 <blockquote><b>Note:</b>
1011
1012 <p><em>Never</em> use the unsupported <tt>dict</tt> or <tt>put</tt>
1013 operators in your option code. These operators are typically used in
1014 option code dating back to Level 1 PostScript printers, which did not
1015 support the simpler <tt>&lt;&lt;</tt> or <tt>&gt;&gt;</tt> operators.
1016 If you have old option code using <tt>dict</tt> or <tt>put</tt>, you can
1017 rewrite it very easily to use the newer <tt>&lt;&lt;</tt> and
1018 <tt>&gt;&gt;</tt> operators instead. For example, the following code
1019 to set the page size:</p>
1020
1021 <style type='text/css'><!--
1022 PRE B {
1023   background: #000000;
1024   color: #ffffff;
1025   padding: 2px 5px;
1026 }
1027 --></style>
1028
1029 <pre class='command'>
1030 <b>1 dict dup</b> /PageSize [612 792] <b>put</b> setpagedevice
1031 </pre>
1032
1033 <p>can be rewritten as:</p>
1034
1035 <pre class='command'>
1036 <b>&lt;&lt;</b> /PageSize [612 792] <b>&gt;&gt;</b> setpagedevice
1037 </pre>
