** Description changed: Installing driver for Canon MP160 has worked perfectly from 12.04 to 13.04, but not anymore in 13.10. The USB printer get detected correctly, but when installing the driver via "New Printer" dialog, only gutenprint can be selected and the "Installing driver gutenprint" dialog just gets stuck and nothing happens. + + + [IMPACT] + + High, as if locally unsupported printers cause a driver download from + OpenPrinting the download ends in an infinite loop and cannot be + cancelled due to a crashed user interaction thread, blocking system- + config-printer completely not allowing a manual setup of the printer. + + [TESTCASE] + + In a terminal window run the commands + + cd /usr/share/system-config-printer/ + python newprinter.py --setup-printer=file:/tmp/printout --devid='MFG:Canon;MDL:MP160;' + + Accept to download the offered Gutenprint driver and enter your password + when you get asked for it.
