Do the following: Turn off and turn on the printer again and from now on do not try to poll the toner levels with CUPS. Your error_log contains jobs where you have sent a command file for polling the toner levels. CUPS recognized this file correctly but instead of using the commandtops filter it passed the command file through to the printer without any filtering. This can have crashed the printer so that all subsequent jobs got ignored.
So try to only print the real jobs after power-cycling the printer, no toner level checks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873548 Title: Brother MFC 7440N printer is detected but will not print To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/873548/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
