please test the new CUPS update as described in comment #42 and check whether you are able to print. Does your Canon print the last page completely? Does your Samsung print more than one job in a row without printing pages with weird characters or error messages? Are you able to print through a Prolific Technology USB->Parallel adapter?
Please give all your feedback here in this bug report as soon as possible, best in a few minutes but at least today, as it is about fixing your problem in Ubuntu Precise 12.04.1 due on Thursday.
