Description
Overview
The world’s most secure printing[2]
The operating code (BIOS) is automatically checked during startup and repairs itself if compromised. Common Criteria certified[3] to continually monitor memory activity to detect and stop attacks in real time. Firmware is automatically checked during startup to determine if it’s authentic code—digitally signed by HP. The printer’s outgoing network connections are inspected to stop suspicious requests and thwart malware.
Easy to use, simple to manage
HP FutureSmart firmware can be updated with the latest features[1] to optimize your investment for years to come. Centralize control of your printing environment with HP Web Jetadmin—and help build business efficiency.[5] Easily enable workflows across your fleet with a consistent user experience and intuitive, tablet-like icons. Expect consistent, high-quality results with technology that automatically adjusts print settings to paper type.
Enhanced productivity to empower workgroups
Give workgroups what they need to succeed. Easily choose and deploy hundreds of HP and third-party solutions. Easily access, print, and share resources with built-in Ethernet and optional wireless networking.[7] Print directly from the 2.7-inch (6.9 cm) color display. Spend less time loading paper with an optional input tray for an additional capacity of 1,200 sheets.
Sustainability is smart business
Help save paper right out of the box. Two-sided (duplex) printing is set at default for automatic savings.[8] Help reduce wasted paper and toner by only printing jobs that are truly needed, using HP Secure Print.[9] Help save energy intelligently by using only the power you need with HP Auto-On/Auto-Off Technology.[10] Help reduce your impact. Count on easy cartridge recycling at no charge with HP Planet Partners.[11]

Dynamic security
Dynamic security enabled printerCertain 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.
