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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1507863 Title: Lost ability to print on LAN printer with 3.16.0-51 kernel Status in linux package in Ubuntu: Incomplete Bug description: After upgrading to new kernel, attempts to print resulted in no printer activity and no error messages.
