It's ink. Depending on the printer you have, you basically have no choice. That being said, this ink will last about 2 months if you are a college student printing out essays weekly. It should last you longer if you only print out occasionally. I would not recommend using those that claim are recycled. The system will recognize that it has been refilled and will not accept it or record it as empty.
