Printing to additional paper tray fails

Version: 4.6 (using KDE 4.6.0)
OS: Linux

We are having strange problems with printing from KDE (4.6.0), kwrite,
konquerer,... When you choose an additional paper
tray (in our case paper source 3), he will allways print from paper source 1.
The driver is the recommend one: HP
LaserJet 2430 Postscript (recommended)

Printing from firefox or libreoffice works without any problem to the desired
paper source. Also the builtin paper tray
2 works perfectly, just the additional 3rd one doesn't work.

Reproducible: Always

Steps to Reproduce:
Print a page from kwrite to an additional paper tray

Actual Results:
Fails. Allways prints to paper tray 1, instead of tray 3.

Expected Results:
Print to desire paper tray.
