Installing Canon Printer Driver in Ubuntu 10.04
I bought a Canon LBP2900B printer yesterday and successfully installed it in Ubuntu (10.4). I had 64 bit Ubuntu installed and hence downloaded the file http://codebin.cotescu.com/canon/lbp_driver/CanonCAPTdriver.tar.gz and executed the command sudo ./canonLBP_install.sh LBP2900 (LBP2900 is same as LBP2900B) after navigating to the directory where i extracted the tar file.
