The PIXMA MP-550 I bought about four weeks ago and am angentan very positive. The scan quality is verblüffent, so the copy results. Printing, scanning and copying speed are top quality. The menu leaves nothing to be desired - simple and user friendly; user-friendly and provided software with which can be photos and printouts designed with many effects. Duplex printing works also very fine. Although you have to turn over the pages and reinsert them in the rear tray, but that is not a problem for me is. Only disadvantage I find it very long warm-up after switching on and the first printing. The printer has a total of five cartridges supplied. Three times color, black for black and white print and a black with Nanotröpfentechnologie for photographic printing. Round I can only recommend this multifunction device and have to say that I got for my money very much. Who prints only at home or for the university / school, scanned or copied - BUY!
