I am using Ubuntu 12.10 32-bit.
The machine detected the network printer Canon MF4800, but it can not find a driver. The screen prompts for a driver. I selected Canon but I cannot find the the series of my printer. I went to the Canon website and searched for a Linux driver but drivers are not not available for the Linux OS.
sudo add-apt-repository ppa:michael-gruz/canon-trunk
at the command line. I'm not sure which drivers you need to install after that or if the print wizard automatically uses the right one. – Tim Tisdall Feb 29 '16 at 14:03
