 814 <h2 class='title'><a name='CONSTRAINTS'>Constraints</a></h2>
 815
 816 <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>
 817
 818 <pre class='command'>
 819 *% Do not allow 2-sided printing on transparency media
 820 *UIConstraints: "*Duplex *MediaType Transparency"
 821 *UIConstraints: "*MediaType Transparency *Duplex"
 822 </pre>
 823
 824 <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>
 825
 826 <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>
 827
 828 <blockquote><b>Note:</b>
 829
 830 <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>

 968 <h2 class='title'><a name='OPTIONS'><span class="info">CUPS 1.3/macOS 10.6</span>Custom Options</a></h2>
 969
 970 <p>CUPS supports custom options using an extension of the <tt>CustomPageSize</tt> and <tt>ParamCustomPageSize</tt> syntax:</p>
 971
 972 <pre class='command'>
 973 *CustomFoo True: "command"
 974 *ParamCustomFoo Name1/Text 1: order type minimum maximum
 975 *ParamCustomFoo Name2/Text 2: order type minimum maximum
 976 ...
 977 *ParamCustomFoo NameN/Text N: order type minimum maximum
 978 </pre>
 979
 980 <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. The CUPS API handles any necessary value quoting for HP-PJL commands. For example, if the JCL command string is "@PJL SET PASSCODE=\1" and the first
 981 option value is "1234" then CUPS will output the string "@PJL SET PASSCODE=1234".</p>
 982
 983 <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. For example, if the PostScript command string is "&lt;&lt;/cupsReal1 2 1 roll&gt;&gt;setpagedevice" and the option value is "2.0" then CUPS will output the string "2.0 &lt;&lt;/cupsReal1 2 1 roll&gt;&gt;setpagedevice".</p>
 984
 985 <p>The "type" is one of the following keywords:</p>
 986
 987 <ul>
 988
 989         <li><tt>curve</tt> - a real value from "minimum" to "maximum" representing a gamma correction curve using the function: f(x) = x <sup>value</sup></li>
 990
 991         <li><tt>int</tt> - an integer value from "minimum" to "maximum"</li>
 992
 993         <li><tt>invcurve</tt> - a real value from "minimum" to "maximum" representing a gamma correction curve using the function: f(x) = x <sup>1 / value</sup></li>
 994
 995         <li><tt>passcode</tt> - a string of numbers value with a minimum of "minimum" numbers and a maximum of "maximum" numbers ("minimum" and "maximum" are numbers and passcode strings are not displayed in the user interface)</li>
 996
 997         <li><tt>password</tt> - a string value with a minimum of "minimum" characters and a maximum of "maximum" characters ("minimum" and "maximum" are numbers and password strings are not displayed in the user interface)</li>
 998
 999         <li><tt>points</tt> - a measurement value in points from "minimum" to "maximum"</li>

1054 <h2 class='title'><a name='RASTERPS'>Writing PostScript Option Commands for Raster Drivers</a></h2>
1055
1056 <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>
1057
1058 <pre class='command'>
1059 *PageSize A4: "&lt;&lt;/PageSize[595 842]&gt;&gt;setpagedevice"
1060 </pre>
1061
1062 <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>
1063
1064 <pre class='command'>
1065 *CustomWatermarkText True: "&lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice"
1066 </pre>
1067
1068 <p>For a custom string value of "My Watermark", CUPS will produce the following PostScript code for the option:</p>
1069
1070 <pre class='command'>
1071 (My Watermark)
1072 &lt;&lt;/cupsString1 3 -1 roll&gt;&gt;setpagedevice
1073 </pre>
1074
1075 <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>
1076
1077 <pre class='command'>
1078 &lt;&lt;/cupsString1(My Watermark)&gt;&gt;setpagedevice
1079 </pre>
1080
1081 <p>The resulting dictionary sets the page device attributes that are sent to your raster driver in the page header.</p>
1082
1083
1084 <h3>Custom Page Size Code</h3>
1085
1086 <p>There are many possible implementations of the <tt>CustomPageSize</tt> code. For CUPS raster drivers, the following code is recommended:</p>
1087
1088 <pre class='command'>
1089 *ParamCustomPageSize Width:        1 points <i>min-width max-width</i>
1090 *ParamCustomPageSize Height:       2 points <i>min-height max-height</i>
1091 *ParamCustomPageSize WidthOffset:  3 points 0 0
1092 *ParamCustomPageSize HeightOffset: 4 points 0 0
1093 *ParamCustomPageSize Orientation:  5 int 0 0
1094 *CustomPageSize True: "pop pop pop &lt;&lt;/PageSize[5 -2 roll]/ImagingBBox null&gt;&gt;setpagedevice"
1095 </pre>
1096
1097
1098 <h3>Supported PostScript Operators</h3>
1099
1100 <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>
1101
1102 <ul>
1103
1104         <li><tt>&lt;&lt;</tt> - Start a dictionary.</li>
1105
1106         <li><tt>&gt;&gt;</tt> - End a dictionary.</li>
1107
1108         <li><tt>[</tt> - Start an array.</li>
1109
1110         <li><tt>]</tt> - End an array.</li>
1111
1112         <li><tt>copy</tt> - Copy the top N objects on the stack.</li>
1113
1114         <li><tt>dup</tt> - Copy the top object on the stack.</li>
1115
1116         <li><tt>index</tt> - Copy the Nth from the top object on the stack.</li>
1117
1118         <li><tt>pop</tt> - Pop the top object on the stack.</li>
1119
1120         <li><tt>roll</tt> - Shift the top N objects on the stack.</li>
1121
1122         <li><tt>setpagedevice</tt> - Set the page header values according to the key/value dictionary on the stack.</li>
1123
1124 </ul>
1125
1126 <blockquote><b>Note:</b>
1127
1128 <p><em>Never</em> use the unsupported <tt>dict</tt> or <tt>put</tt>
1129 operators in your option code. These operators are typically used in
1130 option code dating back to Level 1 PostScript printers, which did not
1131 support the simpler <tt>&lt;&lt;</tt> or <tt>&gt;&gt;</tt> operators.
1132 If you have old option code using <tt>dict</tt> or <tt>put</tt>, you can
1133 rewrite it very easily to use the newer <tt>&lt;&lt;</tt> and
1134 <tt>&gt;&gt;</tt> operators instead. For example, the following code
1135 to set the page size:</p>
1136
1137 <style type='text/css'><!--
1138 PRE B {
1139   background: #000000;
1140   color: #ffffff;
1141   padding: 2px 5px;
1142 }
1143 --></style>
1144
1145 <pre class='command'>
1146 <b>1 dict dup</b> /PageSize [612 792] <b>put</b> setpagedevice
1147 </pre>
1148
1149 <p>can be rewritten as:</p>
1150
1151 <pre class='command'>
1152 <b>&lt;&lt;</b> /PageSize [612 792] <b>&gt;&gt;</b> setpagedevice
1153 </pre>

1749 <p>Due to implementation differences between macOS and Ghostscript,
1750 the <tt>cupsFlipDuplex</tt> keyword is deprecated. Instead, use
1751 the <a href='#cupsBackSide'><tt>cupsBackSide</tt></a> keyword to specify
1752 the coordinate system (pixel layout) of the page data on the back side of
1753 duplex pages.</p>
1754
1755 <p>The value <code>true</code> maps to a <tt>cupsBackSide</tt> value
1756 of <code>Rotated</code> on macOS and <code>Flipped</code> with
1757 Ghostscript.</p>
1758
1759 <p>The default value is <code>false</code>.</p>

1809 valid URI which directs the user at additional information
1810 concerning the condition that is being reported.</p>
