Hello again,

yes, system-config-printer-kde ist installed on my system.

Maybe I should give more details.

Qt4 applications behave like KDE4 applications in the term of printing 
in my case. The printer recognizes the job and all it prints is a blank 
paper, sometimes with header but always without the body.

Printing from Scribus (Qt4) to ps works correctly and from Kate (KDE4) 
to pdf also does.

I have the feeling that it has something to do with pnm2ppa. My printer 
is a HP DeskJet 710C. It seems that Qt has problems with printers that 
need the pnm2ppa layer.

Thanks for your time.
