I have the same issue in Ubuntu 14.04.3 LTS. Printing to my Canon MX870 was fine in 3.13.0-68-generic but Ive been unable to print using any of the later kernels including 3.13.0-74-generic which is the latest I have installed.
As a workaround I print via network routing to another laptop with ubuntu 15.10 kernel 4.2.0-23-generic Could I continue with debugging this issue -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1507863 Title: Lost ability to print on LAN printer with 3.16.0-51 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1507863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
