Ubuntu failed to recognize or find drivers automatically for Canon LBP 3050 Laser printer (USB connected). So I downloaded Linux device driver from the Canon website and installed. And Ubuntu accepted it. But when I try to print something... Nothing happens (means do not print it). What should I do to correct this error?
I think it does not work as this Canon driver uses some kernel modules which are blacklisted (i.e. prevented from loading) by default.
I suggest you uninstall the current Canon driver and follow the instructions here: CanonCaptDrv190 (make sure to read the README file before proceeding).
