Problem with KDE Print

Dear Listmembers, I have a newly installed SuSE 9.2 with KDE 3.4.0 on my laptop. I want to print over a CUPS Server. The server is correctly installed vz. It works seamlessly with another laptop. However on my machine, when I click menu -> print system -> print manager, nothing happens. In Konqueror, klicking on services -> print system browser -> print manager, the print manager remains empty, i.e. no PDF, Fax, Printer. Any ideas ? Thanks a lot !
