The HP LaserJet M140we Laser Printer works efficiently and fits anywhere. The world's smallest multifunction laser in its class designed for efficiency with fast printing and easy mobile solutions. Includes HP+, the smart printing system that keeps you connected and ready to print from virtually anywhere. Compact design that is easy to set up. 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.
