Winning in business means working smarter. The HP Color LaserJet Pro M454 printer is designed to let you focus your time where it’s most effective-helping to grow your business and staying ahead of the competition. 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
