HP printers are specifically designed to be used with cartridges that have a new or reused HP chip or electronic circuitry. These printers utilize dynamic security measures to prevent the use of cartridges with non-HP chips or electronic circuitry. Regular firmware updates are necessary to uphold the effectiveness of these measures and block previously functioning cartridges. A reused HP chip allows for the use of reused, remanufactured, and refilled cartridges. The HP OfficeJet Pro 9100 printer series features advanced Wi-Fi and HP Wolf Pro Security, providing the most reliable and secure technology to stay connected. Internet access is required and must be purchased separately. Wireless operations are compatible with 2.4 GHz and 5.0 GHz networks only. For more information, visit www.hp.com/go/mobileprinting. HP Security is now known as HP Wolf Security. Security features vary by platform; please refer to the product data sheet for details. The percentage of recycled plastic is calculated based on the total weight of plastic.
