Canon all-in-one laser printers
I have found several people who have had problems with Canon all-in-one laser printers. I had huge problems when I first set mine up because it wasn't in Synaptic yet.
There are threads on the forum addressing specific printers, but since the driver wasn't officially supported for very long I think lots of folks have given up the fight.
My thought is that anyone who successfully installed a Canon laser should be able to post to this thread, and/or a link to threads on this or other forums which they found helpful in getting it to work.
The driver as it is shown in Ubuntu 10.10 is cndrvcups-ufr2-uk, and cndrvcups-common.
I have a Canon ImageClass MF8050CN color networked laser which works perfectly with this driver. It supports the networking, although it takes a couple minutes to populate the list of printers when you're setting up. I have not tried the USB port since I have no use for that type of configuration. I have not tried scanning to the computer, only to the USB stick, which works fine.
