I printed 2 cups test pages, a simple text [...Snip...] It does help. Taken with the information in your previous mail and the lack of any obvious misbehaviour shown in the cups error logs, it could be we are looking at something similar to Ubuntu bug #213081 and Debian bug #478062. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/213081 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=478062 The advice offered there is: 1. Power-off the printer to totally clear the corrupt job. 2. Clear the printer spool queue ('cancel -a -x'). 3. Power-on the printer 4. Do '/sbin/sysctl -n net.ipv4.tcp_frto' and confirm the current value is 2. 5. 'sysctl -w net.ipv4.tcp_frto=0' (as root). If it works net.ipv4.tcp_frto=0 is put in /etc/sysctl.conf so that the change survives rebooting. Regards, Brian.
