Your /etc/cups/mime.types looks ok. The unsupported formats indicate that there must be something missing in your CUPS installation. Perhaps their is a cups filter missing. Can you attach your /etc/cups/mime.convs and attach the output of following command: $ ls -l /usr/lib/cups/filter/ You could try to reinstall cups with following command to see if this solves the problem: $ sudo apt-get --reinstall install cupsys -- Printer doesn't work - error 1034 https://launchpad.net/bugs/55283 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
