The problem seems to be Canon's ccp backend. The pipes with which the backend takes in the data have 777 permissions, so jobs get accepted independent with which user rights the backend is executed. The error_log shows that all filters close successfully, only the backend keeps running without issuing any messages until you cancel the job. For me it looks like the backend is broken, so from the Ubuntu side we cannot do anything.
