[ubuntu] Ubuntu 12.04 LTS printer installation problem

view story

http://ubuntuforums.org – Hello, I have installed Ubuntu 12.04 LTS on my PC. But I could not run my Canon i-SENSYS LBP3250 laser printer on it. I have disabled SElinux and also installed CAPT Printer Driver for Linux V2.20 but still my printer is not printing. Whenever I submit a print job, in printer properties it shows 'processing-sending data to printer' but nothing happens! Can anyone help me? (Hardware)
