Same problem here with a KONICA MINOLTA C220 PS after upgrade to 12.04. Some files can be printed fine, some files crashes the printer, forcing it to reboot, some files crashes the printer so hard that I have to pull the printers plug to reboot it.
Here is what the printer spits out just before going to nirvana: ERROR: ioerror OFFENDING COMMAND: --nostringval-- STACK: -mark- -mark- -mark- -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992982 Title: Network printing fails.
