Even after trying everything from the answers of following threads:
2.) How do I install Canon LBP2900B printer in UBUNTU
3.) How to make Canon LBP2900B work on Ubuntu 16.04 LTS?
4.) Installing Canon LBP2900b printer in 12.10
I am still not able to print anything from my computer using UBUNTU 18.04.
But If boot the same computer with Windows 7 OS (It is a Dual Boot Computer with KUBUNTU and Windows 7), the same setup works fine and prints just fine.
Please help me solve this issue.
