HP's entry-level Enterprise-class printer with speeds up to 42 ppm and strongest security. Workteams excel with HP's black-and-white office LaserJet printers, which pack extra punch with high-quality results, extra power, and more features. This printer is intended to work only with cartridges that have a new or reused HP chip, and it uses dynamic security measures to block cartridges using a non-HP chip. Periodic firmware updates will maintain the effectiveness of these measures and block cartridges that previously worked. A reused HP chip enables the use of reused, remanufactured, and refilled cartridges.
