HP DesignJet XT950 MFP Large format printer

Printer with dynamic security. Certain HP printers are intended to work only with cartridges that contain new or reused HP chips or electronic HP circuits. These printers use dynamic security measures to block cartridges that use a chip or electronic circuits that are not from HP. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. Reused HP chips and electronic HP circuits enable the use of reused, recycled, and refilled cartridges.
