We are after a reliable inkjet printer. Our Canon S820 has a terminal case of banding. It will cost about as much as a new printer to replace the print head. Idealy we want something that will do nice postcard size photos. My wife also prints colour flyers for a music group she is part of, so the printer needs to be reliable (and economical if poss). Are Canon printers known for banding problems? I know this is not a Mac specific question but I know the Mac community have great wisdom. Any advice would be greatfully accepted.
