Hello Jens,

thank you for your reply. This is my main problem. I tried to open a service request at novell but they told me, i have only the subscription, no support. I was surprised, that it is possible to buy only the subscription. In our order there was something like BASIC MAINTEANCE, 3 YEAR.
I think this must be a bug in cups or dbus.

Now i don't know how to go on.

Regards
Klaus
