Simple vector graphics printing example?

[Satz Klauer <satzklauer googlemail com>]

Hi,

I plan to print out some vector data using the GTK printing system.

I already found the API description but what I'm missing is a general
overview that describes what has to be used in which order to send such
graphics to a printer.

So my question: is there a simple printing example code or a tutorial
available somewhere that describes how to use the printing functions?
