[Qt-interest] Printing to pdf on windows

[Christopher Rasch-Olsen Raa]

Hi again,

The usual story: you figure it out just after having asked. The addition of 
printer.setOutputFormat(QPrinter::PdfFormat);
did the trick.

Thanks anyway.

Btw; why did the code _just work_ on Linux without the above statement?
