For over a year I have the Canon iP4850. Although I list not a very high-volume printing and a few photos printed, printing costs with original cartridges are too high for me. The printer is very thirsty. The cartridges of youprint I use for almost a year and am very happy with it. But are also very fast empty due to the design of the Canon cartridges. Differences to the print quality of the original cartridges I do not see. When unpacking it drips usually a little bit. The ink cartridges are detected by the printer and are properly available in the Status Monitor.
