I use Ubuntu 14.04. I installed the printer Canon LBP2900 following the guide and did all steps and now the printer works. I added CCPD in Startup Application (with command: sudo /etc/init.d/ccpd start). But after I log out or restart my pc, the printer can't print until I have to open terminal and run sudo /etc/init.d/ccpd restart && sudo /etc/init.d/cups restart. Once more, after restarting my pc I’ve just only printed 1 job (of course it can't print), and I run sudo /etc/init.d/ccpd restart && sudo /etc/init.d/cups restart, the printer will work but it prints the same job three times.
