HP LaserJet printers power office productivity with a smart, streamlined design that’s reliable and hassle-free. Count on premium quality, maximum uptime, and the strongest security[1] – all intended to drive successful organizations forward.

Dynamic security enabled printer Certain HP printers are intended to work only with cartridges that have a new or reused HP chip or electronic circuitry. These printers use dynamic security measures to block cartridges using a non-HP chip or electronic circuitry. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. Reused HP chips and electronic circuitry enable the use of reused, remanufactured, and refilled cartridges.
