Ouch :-/ 
Of course it is either ps.find(re) or ps.find(QRegExp("w\\d+h\\d+"), is any of 
the two better?

I've never used a regexp to capture anything so i thought it would be faster 
to do that than learning how to capture in a QRegExp, is it much worse to use 
that?

That is because doing paintDevice::width() and paintDevice::height() on the 
argument of the method always returns the pageSize of A4 (default page size 
here, calling pageSize() always return A4 too even when option("PageSize") 
says otherwise), i would need to do setPageSize on "printer" as i do on the 
dummy printer but i don't know if that would have side consequences so i 
thought it would be safer to do it on a dummy printer and i don't see any bad 
consequence.
