<h2>Detailed Description</h2>
 
45
<p>The QPrintEngine class defines an interface for how <a href="qprinter.html">QPrinter</a> interacts with a given printing subsystem.</p>
 
46
<p>The common case when creating your own print engine is to derive from both <a href="qpaintengine.html">QPaintEngine</a> and QPrintEngine. Various properties of a print engine are given with <a href="qprintengine.html#property">property</a>() and set with <a href="qprintengine.html#setProperty">setProperty</a>().</p>
