Version: (using KDE 4.2.1) OS: Linux Installed from: Fedora RPMs As long as I just want to print to a local printer, there is no problem at all. When I bring my laptop to work however, I have to edit /etc/cups/client to list the company print server: ServerName <server url> After I restart the cups service, KDE apps don't print anymore. They completely hang, immediately after pressing 'Print' (so no dialog shows up) and have to be killed. Also system-config-printer-kde now gives an empty window and hangs. Non-kde-apps keep working fine. OpenOffice eg. now shows all available printers in the building. Also system-config-printer lists all printers.
Thanks for reporting. This is a but inside Qt which is being investigated. *** This bug has been marked as a duplicate of bug 179955 ***
