Could you give me an example how to do that, please? It's enough when you point out the steps to get there, not a full explanation.

I tried with this "FakePrinter" configuration, but I get the error:
Raw printers cannot use file: devices!

I assume what I'm trying to do here is complete nonsense ... ;-)

<Printer FakePrinter>

Many thanks in advance
