[CentOS] Printer-Problems

Hi Folks,

fresh CentOS 5.5 x86_64.
One USB-printer connected (HP Business Inkjet 1200)
Printing from localhost:631  (Testpage) works.
But no from any application.
From OO only the message: printer-problem - no more.
Second printer is from far (Cupsd) in the network.
Works well.

But what's about the local printer?

Any hints?

Thx
Timothy
