<h2>Detailed Description</h2>
<p>The QPrinterInfo class gives access to information about existing printers.</p>
<p>Use the static functions to generate a list of QPrinterInfo objects. Each QPrinterInfo object in the list represents a single printer and can be queried for name, supported paper sizes, and whether or not it is the default printer.</p>

<h2>Member Function Documentation</h2>
<a name="//apple_ref/cpp/instm/QPrinterInfo/QPrinterInfo"></a>
<h3 class="fn"><a name="QPrinterInfo"></a>QPrinterInfo::QPrinterInfo ()</h3>
<p>Constructs an empty <a href="qprinterinfo.html">QPrinterInfo</a> object.</p>
<p>See also <a href="qprinterinfo.html#isNull">isNull</a>().</p>
<h3 class="fn"><a name="QPrinterInfo-2"></a>QPrinterInfo::QPrinterInfo ( const QPrinterInfo & <i>src</i> )</h3>
<p>Constructs a copy of <i>src</i>.</p>
<h3 class="fn"><a name="QPrinterInfo-3"></a>QPrinterInfo::QPrinterInfo ( const <a href="qprinter.html">QPrinter</a> & <i>printer</i> )</h3>
<p>Constructs a <a href="qprinterinfo.html">QPrinterInfo</a> object from <i>printer</i>.</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/~QPrinterInfo"></a>
<h3 class="fn"><a name="dtor.QPrinterInfo"></a>QPrinterInfo::~QPrinterInfo ()</h3>
<p>Destroys the <a href="qprinterinfo.html">QPrinterInfo</a> object. References to the values in the object become invalid.</p>
<a name="//apple_ref/cpp/clm/QPrinterInfo/availablePrinters"></a>
<h3 class="fn"><a name="availablePrinters"></a><a href="qlist.html">QList</a><QPrinterInfo> QPrinterInfo::availablePrinters () <tt> [static]</tt></h3>
<p>Returns a list of available printers on the system.</p>
<a name="//apple_ref/cpp/clm/QPrinterInfo/defaultPrinter"></a>
<h3 class="fn"><a name="defaultPrinter"></a>QPrinterInfo QPrinterInfo::defaultPrinter () <tt> [static]</tt></h3>
<p>Returns the default printer on the system.</p>
<p>The return value should be checked using <a href="qprinterinfo.html#isNull">isNull</a>() before being used, in case there is no default printer.</p>
<p>See also <a href="qprinterinfo.html#isNull">isNull</a>().</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/isDefault"></a>
<h3 class="fn"><a name="isDefault"></a>bool QPrinterInfo::isDefault () const</h3>
<p>Returns whether this printer is the default printer.</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/isNull"></a>
<h3 class="fn"><a name="isNull"></a>bool QPrinterInfo::isNull () const</h3>
<p>Returns whether this <a href="qprinterinfo.html">QPrinterInfo</a> object holds a printer definition.</p>
<p>An empty <a href="qprinterinfo.html">QPrinterInfo</a> object could result for example from calling <a href="qprinterinfo.html#defaultPrinter">defaultPrinter</a>() when there are no printers on the system.</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/printerName"></a>
<h3 class="fn"><a name="printerName"></a><a href="qstring.html">QString</a> QPrinterInfo::printerName () const</h3>
<p>Returns the name of the printer.</p>
<p>See also <a href="qprinter.html#setPrinterName">QPrinter::setPrinterName</a>().</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/supportedPaperSizes"></a>
<h3 class="fn"><a name="supportedPaperSizes"></a><a href="qlist.html">QList</a><<a href="qprinter.html#PaperSize-enum">QPrinter::PaperSize</a>> QPrinterInfo::supportedPaperSizes () const</h3>
<p>Returns a list of supported paper sizes by the printer.</p>
<p>Not all printer drivers support this query, so the list may be empty. On Mac OS X 10.3, this function always returns an empty list.</p>
<p>This function was introduced in Qt 4.4.</p>
<a name="//apple_ref/cpp/instm/QPrinterInfo/operator="></a>
<h3 class="fn"><a name="operator-eq"></a>QPrinterInfo & QPrinterInfo::operator= ( const QPrinterInfo & <i>src</i> )</h3>
<p>Sets the <a href="qprinterinfo.html">QPrinterInfo</a> object to be equal to <i>src</i>.</p>
