This cartridge-free printer delivers impeccable quality and includes enough ink for up to 3 years. With DualBand Wi-Fi, you can connect faster and print more easily from your mobile device using the HP Smart App. Some HP printers are designed for use only with cartridges that have HP's original or reused chips or electronic circuits. These printers employ dynamic security measures to block cartridges that contain a non-HP chip or non-HP electronic circuit. Regular firmware updates maintain the effectiveness of these measures and may block cartridges that previously worked. Reused HP chips and electronic circuits from HP allow for the use of reused, remanufactured, and refilled cartridges.
