It also lets you easily create Pango::Layout and Pango::Context objects that match the font metrics of the cairo surface.
PrintContext objects gets passed to the begin-print, end-print, request-page-setup and draw-page signals on the PrintOperation.

Sets a new cairo context on a print context.
This function is intended to be used when implementing an internal print preview, it is not needed for printing, since GTK+ itself creates a suitable cairo context in that case.
