I just want to purchase a black and white cartridge

Much more reliable than cheap refills.

Clean Replacement; Long Cartridge Life

I only wish toner wasn't so expensive, but that's just part of the game. This toner was exactly what I expected, arrived quickly, and installed without issue.

No Comment.

- high quality printing; better than Brother MFC - cartridges are easier to refill and replace; than Brother MFC - more cost-effective than Brother MFC

- network faxing is slower than Brother MFC

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.

Cartridge performs as well as very first cartridge

This toner cartridge is designed for use with the HP Laserjet 5P and 6P laser printers. These toners are used extensively at the company I work for as we have a number of 6P printers. The 03A is a black ink cartridge with an estimated life of 8,000 pages.
