I am having the same problem with Canon LBP 4U printer. The error was occurring with cjet (recommended) driver. With the instructions given here, Itried lbp8 driver and it worked. I have been using the printer (auto-edtected) with cjet driver without any problems in dapper. Now having a fresh install of Feisty and I was not able to print until found these tips from here.
