After upgrade from 14.04 to 14.10, I can not use my (SAMBA) network printer anymore. Jobs stay in the que forever. When I go to 'Printers' and ask for the properties of the printer, I get the message: "There was a problem connecting to the CUPS server".
In Firefox I can browse localhost:631 (as mentioned in another post on this forum, not from me) and the printer is visible. When trying to print a test page from there, I get another error message: Connection failed: NT_STATUS_CONNECTION_REFUSED. For me, this is totally uncomprehensible.
With 14.04 and before, it worked like a charm. I have tried to install the printer again, to no avail. The printserver is not found, the printer not seen.
(And, not related, but my computer is a lot slower since this 'upgrade'. Think I'll go back to 14.04. Wish I had made an image of my harddisk, as a usually do before any upgrade. Until now, every upgrade went smooth, so I figured I could skip this time. And of course...)
