When I bought my HP Color Laserjet I knew replacement cartridges were expensive. But I wasn't prepared for the sticker shock when it came time to order. So I decided to take a chance and buy a set of those "non-hp" cartridges that HP tries to scare you away from. Turns out none of the scare tactics were true. The cartridges fit perfectly, were easy to install, and did not generate anything more than a gentle reminder that the cartridges were not "HP". As for the print quality... looks exactly the same to me. Here's the best news. A full set of four cost me far less than buying even one cartridge from the manufacturer. Add to that my communication with the company was excellent. Overall a great experience.
