<div class="section" id="introduction">
<h2>introduction</h2>
<p>CupsPrintIPP is an extension of class library of PrintIPP. It implements operations which are not part of
Internet Printing Protocol as described by RFCs.</p>
<p>It is built on CUPS-IPP-1.1 document.</p>
</div>
<div class="section" id="responseparsing">
<h2>response parsing</h2>
<div class="subsection" id="p1">
<h3>printer-type attribute</h3>
Cups adds an attribute named "printer-type" to printer's attributes.<br />
Example:
<pre class="pre">
echo "Printer attributes for printer $i:<pre>\n"; print_r($ipp->printer_attributes); echo "</pre>";
if (isset($ipp->printer_attributes->printer_type->_value2)
&& ($ipp->printer_attributes->printer_type->_value2) == 'print-black')
echo "The printer can print black<br />\n";
if (isset($ipp->printer_attributes->printer_type->_value3)
&& ($ipp->printer_attributes->printer_type->_value3) == 'print-color')
echo "The printer can print color<br />\n";
</pre>
</div>
</div>
<div class="section" id="functionsreference">
<h2>functions reference</h2>
<div class="subsection" id="funcops">
<h3>Operations</h3>
<div class="subsubsection" id="o1">
<h4>cupsGetDefault()</h4>
Get default printer attributes. Parsing is same as getPrinterAttributes() operation of
standard PrintIPP class. Note that printer history is given as RFC3382 "collection",
which needs a different handling.<br />
Example:
<pre class="pre">
$ipp->cupsGetDefaults(array('all'));
echo "</pre>\nPrinter historic for default printer:\n";
$histo = $ipp->printer_attributes->printer_state_history->_value1;
$idx_histo = "_indice0";
for ($idx = 0 ; isset($histo->$idx_histo) ; $idx ++) {
echo "<h3>next event:</h3>\n";
foreach ($histo->$idx_histo as $key => $value) {
if (is_object($value))
if ($key != 'printer_state_time')
printf("%s: %s<br />",$key,$value->_value0);
else
printf("%s: %s<br />",$key,date('Y-m-d H:i:s',$value->_value0));
$idx_key = "_key". ($key + 1);
}
$idx_histo = '_indice'. ($idx + 1);
}
</pre>
</div>
<div class="subsubsection" id="o2">
<h4>cupsRejectJobs($printer_uri,$printer_state_message=false)</h4>
Causes CUPS rejecting jobs for given printer.
</div>
<div class="subsubsection" id="o3">
<h4>cupsAcceptJobs($printer_uri)</h4>
Causes CUPS accepting jobs for given printer.
</div>
<div class="subsubsection" id="o4">
<h4>cupsGetPrinters()</h4>
Alias for getPrinters().
