I've got excatly the same problem with a HP PSC 1510 which however is absolutely recognized.
It's possible to print when it's directly connected to the PC. On the other hand, when it's connected on the network using my LiveBox2 I get the message "cups-ipp-missing-validate-job" and "Print file was not accepted". I'd like to indicate I'm not alone as this can show it http://forum.ubuntu-fr.org/viewtopic.php?id=685831 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/881843 Title: CUPS IPP print to Novell servers error since 11.10 upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/881843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
