Hello,

I want to report about the situation again.

Nothing has changed with the release of KDE SC 4.4.1 and Qt 4.6. The 
printing from KDE or Qt applications works only in rare cases.

Kate prints only the header including the date but not the body of a 
text file, Okular often prints pdf documents without graphics and 
Gwenview has never printed any pixel of an image file on my system. In 
every case the printer behaved commonly excepting the result on the paper.

On the other side printing from KDE or Qt applications to pdf or ps 
works as expected, also for normal printing from GNOME and GTK 
applications and from OpenOffice, Firefox and Thunderbird.


Bye
Lars
