Martin Wilck, in general regarding "policies" and CUPS you may have a look at https://bugzilla.suse.com/show_bug.cgi?id=827331 therein in particular https://bugzilla.suse.com/show_bug.cgi?id=827331#c11 for an overview about the possible mess. I don't know the current state. A side note FYI: I do not use a desktop (I use X with a plain windowmanager). This way things are simple and straightforward (KISS) and my working gets much less disturbed by side issues ;-)
