Summary: Great printer great cartridge. If I had it to do over again I would get the very same thing.
Pros: I think I get almost 10,000 or 2 boxes of paper out of a cartridge at least. Great printer. I loved it so much at work I bought one for my personal use. I have used these cartridges for many years now and love the fact that I dont have to replace them very often.
Cons: none. When they get low on ink I swish them side to side and sometimes get 500 more copies out of it which gives me time to order the next one.
Summary: Delivered on time and in excellent condition. I have been using the HP color laserjet 2550n for over 18 months with no problems. The black cartridge, which I mostly use, lasts about 10 months in my office.
Pros: Cartridge performs as well as very first cartridge.
