http://ubuntuforums.org – Cant print! I have setup my Canon mp620 according to several posts as a network printer but when I try to print I get "Processing - Failed to read side channel request" The printer is unable to print even a test page. I initially tried to get it to work by USB but this appears to have a similar result except that the print jobs appear to be sent with no result at all. Any help would be appreciated. (Hardware)
