HP’s entry-level Enterprise-class printer with speeds up to 42 ppm[9] and strongest security.[1] Product disclaimer This printer is intended to work only with cartridges that have a new or reused HP chip, and it uses dynamic security measures to block cartridges using a non-HP chip. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. A reused HP chip enables the use of reused, remanufactured, and refilled cartridges. More at: More at http://www.hp.com/learn/ds
