.SH "Detailed Description"
.PP 
A base class for plot print filters\&. 

A print filter can be used to customize \fBQwtPlot::print()\fP\&.
.PP
\fBDeprecated\fP
.RS 4
In Qwt 5\&.0 the design of \fBQwtPlot\fP allows/recommends writing individual QwtPlotItems, that are not known to \fBQwtPlotPrintFilter\fP\&. So this concept is outdated and \fBQwtPlotPrintFilter\fP will be removed/replaced in Qwt 6\&.x\&.
