G5 with OS x 10.4.11 printing over the network to Canon i RC5180. tried both PSv3 and UFRII drivers, tried adding the printer with every conceivable configuration and the result is either unable to print due to job being stopped or it acts like it was printed but the copier doesn't actually print anything. I have tried repairing disk permissions with no luck. I've gotten two errors, though not consistently, error -50 and error -3150. I really appreciate any help anyone can provide.
