I have not tried scanning to the computer, only to the USB stick, which works fine. I have not tried the USB port since I have no use for that type of configuration. It supports the networking, although it takes a couple minutes to populate the list of printers when you're setting up. I have a Canon ImageClass MF8050CN color networked laser which works perfectly with this driver.
The driver as it is shown in Ubuntu 10.10 is cndrvcups-ufr2-uk, and cndrvcups-common. 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. 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.
I had huge problems when I first set mine up because it wasn't in Synaptic yet. I have found several people who have had problems with Canon all-in-one laser printers.
