John & Guido; can you please send the output of the following commands to the bugreport (as root)? # grep -E 'WebInterface|Listen' /etc/cups/cupsd.conf # lpstat -H If the first doesn't show "Listen localhost:631" but the latter outputs "localhost:127", then these are occurences of bug #792730. Cheers, OdyX P.S. I'll upload cups 2.0.3-9 as soon as I get feedback on #792731
