I have a Cannon printer and I have gotten my cartridges refilled at a local refill store and I have used their brand with no problems. As for paper, I have used many different brands especially Staples also without any problems. The only paper I had a problem with was with the "Everyday HP Paper" and if you read the fine print it tells you not to use it with Cannon Printers. I figure by the time I have a problem with my printer from generic ink I will want a new updated printer by then anyways. Happy Printing!
