files by checking the <code>printer-type</code> attribute for the
<code>CUPS_PRINTER_COMMANDS</code> capability bit.</p>
+<p>In addition, the PPD file for a printer can contain a
+<code>cupsCommands</code> keyword that provides a list of supported
+commands separated by spaces, for example:</p>
+
+<pre class='command'>
+*cupsCommand: "AutoConfigure Clean PrintSelfTestPage ReportLevels"
+</pre>
+
+<p>If no <code>cupsCommands</code> keyword is provided, the command filter
+must support <a href='#AutoConfigure'><code>AutoConfigure</code></a>,
+<a href='#Clean'><code>Clean</code></a>,
+<a href='#PrintSelfTestPage'><code>PrintSelfTestPage</code></a>,
+and <a href='#ReportLevels'><code>ReportLevels</code></a>. The scheduler also
+provides the <code>printer-commands</code> attribute containing the list of
+supported commands.</p>

-<p>The printer commands are described below. Printer commands are
-case-insensitive, so "PRINTSELFTESTPAGE", "printselftestpage",
-and "PrintSelfTestPage" are equivalent. Commands that accept
-arguments have their arguments on the same line separated by
-whitespace.</p>
+<p>Commands are any sequence of letters, numbers, and punctuation characters
+optionally followed by parameters separated by whitespace, e.g.:</p>
+
+<pre class='command'>
+Clean all
+PrintSelfTestPage
+</pre>
+
+<p>Command names are case-insensitive, so "PRINTSELFTESTPAGE",
+"printselftestpage", and "PrintSelfTestPage" are equivalent. Vendor-specific
+commands should use a domain name prefix, e.g.:</p>
+
+<pre class='command'>
+com.vendor.foo
+com.vendor.bar param param2 ... paramN
+</pre>
+

+<h2 class='title'><a name='COMMANDS'>Standard Commands</a></h2>
-<h2 class='title'><a name='COMMANDS'>Commands</a></h2>
+<p>The following are the standard commands supported by the format. The only
+required command is

-<p>Does a standard print head cleaning. If a printer does not
-support cleaning of individual colors or cartridges, then all
-print heads are cleaned. Command filters MUST support the "all"
-colorname. Other standard color names include "black", "color",
-"photo", "cyan", "magenta", "yellow", "light-cyan",
-"light-magenta", "light-black", "light-gray", and
-"dark-gray".</p>
+<p class='summary'>AutoConfigure</p>
+
+<p>The <code>AutoConfigure</code> command updates the printer's PPD file
+and driver state information to reflect the current configuration of the
+printer. There are no arguments for this command.</p>
+
+<p>Example:</p>
+
+<pre class='command'>
+#CUPS-COMMAND
+AutoConfigure
+</pre>
+
+
+<h3><a name='Clean'>Clean</a></h3>
+
+<p class='summary'>Clean <i>colorname</i></p>
+
+<p>The <code>Clean</code> command performs a standard print head cleaning. The
+"colorname" parameter specifies which color or head to clean. If a printer does
+not support cleaning of individual colors or cartridges, then all colors are
+cleaned. Command filters MUST support the "all" colorname. Other standard color
+names include "black", "color", "photo", "cyan", "magenta", "yellow",
+"light-cyan", "light-magenta", "light-black", "light-gray", and "dark-gray".</p>
<p>Example:</p>
Clean all
</pre>
-<h3>PrintSelfTestPage</h3>
+
+<h3><a name='PrintAlignmentPage'>PrintAlignmentPage</a></h3>
+
+<p class='summary'>PrintAlignmentPage pass</p>
+
+<p>The <code>PrintAlignmentPage</code> command prints a head alignment page on
+the printer. The "pass" parameter provides a pass number from 1 to N. The number
+of passes is device-dependent.</p>
+
+<p>Example:</p>
+
+<pre class='command'>
+#CUPS-COMMAND
+PrintAlignmentPage 1
+</pre>
+
+
+<h3><a name='PrintSelfTestPage'>PrintSelfTestPage</a></h3>
<p class='summary'>PrintSelfTestPage</p>
-<p>Print a self-test page on the printer. Typically this page
-shows if all jets on a print head are functioning properly.</p>
+<p>The <code>PrintSelfTestPage</code> command prints a self-test page on the
+printer. Typically this page shows whether all jets on a print head are
+functioning and that the print feed mechanisms are working properly.</p>
<p>Example:</p>
PrintSelfTestPage
</pre>
+
+<h3><a name='ReportLevels'>ReportLevels</a></h3>
+
+<p class='summary'>ReportLevels</p>
+
+<p>The <code>ReportLevels</code> command queries the supply levels on a printer
+and reports "marker-colors", "marker-levels", "marker-names", and
+"marker-types" attributes using "ATTR:" messages sent to the scheduler.</p>
+
+<p>Example:</p>
+
+<pre class='command'>
+#CUPS-COMMAND

+
+
+<h3><a name='SetAlignment'>SetAlignment</a></h3>
+
+<p class='summary'>SetAlignment pass value ... valueN</p>
+
+<p>The <code>SetAlignment</code> command sets print head alignment values. The
+"pass" parameter is a number from 1 to N. All parameters are
