QPrintEngine Class Reference
^{[QtGui module]}

Detailed Description

The QPrintEngine class defines an interface for how QPrinter interacts with a given printing subsystem.

The common case when creating your own print engine is to derive from both QPaintEngine and QPrintEngine. Various properties of a print engine are given with property() and set with setProperty().
