Ubuntu 11.10 & usb printers
Ubuntu has released 11.10 some time ago which broke my CUPS printserver somehow.
After using sometime debugging CUPS. I somehow came by a bug report about the kernel used in ubuntu 11.10 which breaks usb printing in general(I think that such thing should have found in the RC phase). I think it is an essential thing that should be fixed quick, but it seems that there is not a fixed kernel in the normal stable repository yet, so we have to used the proposed repository.
So all it takes is adding a source like the normal ones in /etc/apt/sources.list but with oneiric-proposed instead of just oneiric
That fixed my problem and cups could just detect my usb printer and I could add it in the webinterface again
– update – The “normal” ubuntu kernel is actually working fine now :)
