I moved from 12.04 to 14.04 and I am no more able to print.
This is a network printer and if I try to print something the printer completely freezes (one need to restart it by unplugging the supply !).
The printer is a Konica Minolta BizHub C280.
I have tryed 3 different Ubuntu installations: - Ubuntu 14.04 (64bits) - Xubuntu 14.04 (64bits) - Ubuntu 14.04 (32bits) [as my 12.04 was a 32bits)
I think the short term solution is to come back to 12.04 !
