Installing Canon LBP2900b printer in 12.10
I installed Canon LBP2900B 's driver from canon's support page in Ubuntu 12.10. In printers section it is showing my printer as LBP2900 (not as LBP2900B). I can open its properties, can send a command for printing. What's wrong, however, is that in the printing process, it is shown as processing. Suffice it to say that my printer is not working.
See this page of the Ubuntu help wiki and follow the instructions for 12.04.
