It's printer ink. Does what it's supposed to - print. It's a necessary evil. It's overpriced and dries before I ever get a chance to finish it. Probably cheaper to buy a new printer than ink but why add so much waste to the environment because your company can't come up with an affordable, less wasteful alternative. I'm sure you'll discontinue this model number soon forcing me to buy a new printer and even more expensive ink. Glad I can keep your executives comfortable and set for life.
