<h2 class='title'><a name='ATTRIBUTES'>General Attributes</a></h2>
-<h3>cupsFilter</h3>
+<h3>APDuplexRequiresFlippedMargin</h3>
+
+<p class='summary'>*APDuplexRequiresFlippedMargin: boolean</p>
-<p>This string attribute provides a conversion rule of the
-form:</p>
+<p>This boolean attribute notifies the RIP filters that the
+destination printer does not require the top and bottom margins
+of the <tt>ImageableArea</tt> swapped for the back page. The
+default value is <code>true</code>.</p>
+
+<p>Example:</p>
<pre class='command'>
-source/type cost program
+<em>*% Don't swap the top and bottom margins for the back side</em>
+*APDuplexRequiresFlippedMargin: false
</pre>
-<p>The destination type is assumed to the printer's type. If a
-printer supports the source type directly, the special filter
-program "-" may be specified.</p>
+<p>Also see the related <tt>cupsFlipDuplex</tt> attribute.</p>
+
+<h3>cupsFilter</h3>
+
+<p class='summary'>*cupsFilter: "source/type cost program"</p>
+
+<p>This string attribute provides a conversion rule from the
+given source type to the printer's native format using the
+filter "program". If a printer supports the source type directly,
+the special filter program "-" may be specified.</p>
<p>Examples:</p>
<h3>cupsFlipDuplex</h3>
+<p class='summary'>*cupsFlipDuplex: boolean</p>
+
<p>This boolean attribute notifies the RIP filters that the
destination printer requires an upside-down image for the back
-page. The default value is false.</p>
+page. The default value is <code>false</code>.</p>
<p>Example:</p>
*cupsFlipDuplex: true
</pre>
+<p>Also see the related <tt>APDuplexRequiresFlippedMargins</tt> attribute.</p>
+
+<h3>cupsLanguages</h3>
+
+<p class='summary'>*cupsLanguages: "locale list"</p>
+
+<p>This attribute describes which language localizations are
+included in the PPD. The "locale list" string is a space-delimited
+list of locale names ("en", "en_US", "fr_FR", etc.)</p>
+
+<p>Example:</p>
+
+<pre class='command'>
+<em>*% Specify Canadian, UK, and US English, and Candian and French French</em>
+*cupsLanguages: "en_CA en_UK en_US fr_CA fr_FR"
+</pre>
+
<h3>cupsManualCopies</h3>
+<p class='summary'>*cupsManualCopies: boolean</p>
+
<p>This boolean attribute notifies the RIP filters that the
destination printer does not support copy generation in
-hardware. The default value is false.</p>
+hardware. The default value is <code>false</code>.</p>
<p>Example:</p>
<h3>cupsModelNumber</h3>
+<p class='summary'>*cupsModelNumber: number</p>
+
<p>This integer attribute specifies a printer-specific model
number. This number can be used by a filter program to adjust
the output for a specific model of printer.</p>
<h3>cupsPortMonitor</h3>
+<p class='summary'>*cupsPortMonitor urischeme/Descriptive Text: "port monitor"</p>
+
<p>This string attribute specifies printer-specific "port
monitor" filters that may be used with the printer. The CUPS
scheduler also looks for the <tt>Protocols</tt> attribute to see
respectively) is listed in the printer's
<tt>port-monitor-supported</tt> attribute.</p>
+<p>The "urischeme" portion of the attribute specifies the URI scheme
+that this port monitor should be used for. Typically this is used to
+pre-select a particular port monitor for each type of connection that
+is supported by the printer. The "port monitor" string can be "none"
+to disable the port monitor for the given URI scheme.</p>
+
<p>Examples:</p>
<pre class='command'>
<em>*% Specify a PostScript printer that supports the TBCP protocol</em>
*Protocols: TBCP PJL
+<em>*% Specify that TBCP should be used for socket connections but not USB</em>
+*cupsPortMonitor socket/AppSocket Printing: "tbcp"
+*cupsPortMonitor usb/USB Printing: "none"
+
<em>*% Specify a printer-specific port monitor for an Epson USB printer</em>
-*cupsPortMonitor epson-usb/USB Status Monitor: "epson-usb"
+*cupsPortMonitor usb/USB Status Monitor: "epson-usb"
</pre>
<h3>cupsVersion</h3>
+<p class='summary'>*cupsVersion: major.minor</p>
+
<p>This required attribute describes which version of the CUPS
PPD file extensions was used. Currently it must be the string
"1.0", "1.1", or "1.2".</p>
*cupsVersion: "1.2"
</pre>
+<h3>ippReason</h3>
+
+<p class='summary'>*ippReason reason/Reason Text: "optional URL"</p>
+
+<p>This optional attribute maps custom
+<code>printer-state-reasons</code> keywords that are generated by
+the driver to human readable text. The optional URL string is a
+CUPS server absolute path to a help file under the scheduler's
+<code>DocumentRoot</code> directory or a full URL
+("http://www.domain.com/path/to/help/page.html") which directs
+the user at additional information concerning the condition that
+is being reported.</p>
+
+<p>Examples:</p>
+
+<pre class='command'>
+<em>*% Map com.vendor-error to text but no page</em>
+*ippReason com.vendor-error/A serious error occurred: ""
+
+<em>*% Map com.vendor-error to text and a local page</em>
+*ippReason com.vendor-error/A serious error occurred: "/help/com.vendor/error.html"

+<em>*% Map com.vendor-error to text and a remote page</em>
+*ippReason com.vendor-error/A serious error occurred: "http://www.vendor.com/help"
+</pre>
<h2 class='title'><a name='OPTIONS'>Custom Options</a></h2>
<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.</p>
+any necessary value quoting for HP-PJL commands. For example, if
+the JCL command string is "@PJL SET PASSCODE=\1" and the first
+option value is "1234" then CUPS will output the string
+"@PJL SET PASSCODE=1234".</p>
<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.</p>
-
-<blockquote><b>Note:</b> Currently only CustomPageSize supports
-more than 1 parameter. This restriction is due to value encoding
-issues, since the "Custom.value" format does not allow for
-specification of named parameters. We anticipate supporting the
-collection value format "{Name1=foo Name2=bar}" for the final
-CUPS 1.2 release. In addition, the collection value format will
-allow string values to contain spaces.</blockquote>
+placed on the stack before the command. For example, if the
+PostScript command string is
+"<</cupsReal1 2 1 roll>>setpagedevice" and the
+option value is "2.0" then CUPS will output the string
+"2.0 <</cupsReal1 2 1 roll>>setpagedevice".</p>
<p>The "type" is one of the following keywords:</p>
<li><tt>passcode</tt> - a string of numbers value with a
minimum of "minimum" numbers and a maximum of "maximum"
- numbers (passcode strings are not displayed in the user

<h2 class='title'><a name='PROFILES'>Color Profiles</a></h2>
+<p>CUPS supports two types of color profiles. The first type is
+based on sRGB and is used by the standard CUPS raster filters and
+ESP Ghostscript. The second type is based on ICC profiles and is
+used by the Core Graphics-based filters on MacOS X.</p>
+
+<blockquote><b>Note:</b> At this time, none of the CUPS raster
+filters support ICC profiles. This will be addressed as time
+and resources permit.</blockquote>
+
<h3>cupsColorProfile</h3>

+transform matrix.</p>
<p>The <i>Resolution</i> and <i>MediaType</i> values may be "-"
to act as a wildcard. Otherwise they must match one of the

<p>CUPS 1.2 and higher adds support for PPD files containing multiple
-languages by following the following rules:</p>
+languages by following the following additional rules:</p>
<ol>
- <li>The <tt>LanguageVersion</tt> is <tt>English</tt></li>
+ <li>The <tt>LanguageVersion</tt> MUST be <tt>English</tt></li>
+
+ <li>The <tt>LanguageEncoding</tt> MUST be <tt>ISOLatin1</tt></li>
+
+ <li>The <tt>cupsLanguages</tt> attribute MUST be provided and
+ list each of the supported locales in the PPD file</li>
+
+ <li>Main and option keywords MUST NOT exceed 34 (instead of 40)
+ characters to allow room for the locale prefixes in translation
+ attributes</li>
- <li>The <tt>LanguageEncoding</tt> is <tt>ISOLatin1</tt></li>
+ <li>The main keyword "Translation" MUST NOT be used</li>
- <li>Main and option keywords may not exceed 34
- characters, which is a subset of what the Adobe PPD spec
- allows.</li>
+ <li>Translation strings included with the main and option
+ keywords MUST NOT contain characters outside the ASCII
+ subset of ISOLatin1 and UTF-8; developers wishing to use
+ characters outside ASCII MUST provide a separate set of
+ English localization attributes for the affected keywords.</li>
- <li>Translations are specified using a locale prefix of
+ <li>Localizations are specified using a locale prefix of
the form "ll" or "ll_CC." where "ll" is the 2-letter ISO
language code and "CC" is the 2-letter ISO country
code</li>
- <li>Translation strings are encoded using UTF-8.</li>
+ <li>Locale-specific translation strings MUST be encoded
+ using UTF-8.</li>
- <li>Main keywords are translated using any of the
+ <li>Main keywords MUST be localized using one of the
following forms:
<p><tt>*ll.Translation MainKeyword/translation
text: ""</tt><br />
<tt>*ll_CC.Translation MainKeyword/translation
text: ""</tt></p></li>
- <li>Option keywords are translated using any of the

text: ""</tt></p></li>
+ <li>Localization attributes MAY appear anywhere after the
+ first line of the PPD file</li>
+
</ol>
-<p>Examples:</p>
+<blockquote><b>Note:</b>
+We use a <tt>LanguageEncoding</tt> value of <tt>ISOLatin1</tt>
+and limit the allowed base translation strings to ASCII to avoid
+character coding issues that would otherwise occur. In addition,
+requiring the base translation strings to be in English allows
+for easier fallback translation when no localization is provided
+in the PPD file for a given locale.</blockquote>
