Paul, which printer are you using? Does it actually support the functionality you are requesting? The "Print Self Test Page" is intended for printers which have a built in self test page (usually to discover clogged nozzles) and the driver is supposed to send a special code sequence to the printer to make the printer print this test page (not send a test page from the computer to the printer). "Clean Heads" is supposed to tell the printer to run its internal cleaning cycle.
Unfortunately, the buttons sometimes appear in the Properties dialog of system-config-printer if the printer does not have the mentioned functionality, for example with the virtual "PDF" printer which gets created when installing the cups-pdf package (there are really no print heads to clean). Or are you developing printer maintenance support for your Kodak driver? ** Changed in: system-config-printer (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500636 Title: commands passed to cups fail.
