Designed for corporate workgroups that need professional performance with fast, high-quality two-sided colour printing with scan and copy functionality and award-winning reliability in a compact design. Printers with dynamic security. Some HP printers are designed for use only with cartridges that have new or reused HP chips or electronic circuitry. These printers use dynamic security measures to block print cartridges with a non-HP chip or non-HP electronic circuit. Regular firmware updates maintain the effectiveness of these measures and block cartridges that previously worked. Reused HP chips and HP electronic circuits allow the use of reused, remanufactured and refilled print cartridges.
