LaserJet M521DN
The HP LaserJet M521DN comes from the late-2000s, when a mono single-function printer was judged on uptime — and the LaserJet M521DN judged well. The LaserJet M521DN was purpose-built for everyday office document printing, and it handles that workload with unhurried confidence.
Like 39 other models in its family, the LaserJet M521DN takes the HP 55A/55X cartridge line — look for the CE255A. We stock both quality-compatible HP 55A/55X cartridges and genuine OEM CE255A supplies for the LaserJet M521DN, so you can match your budget to your print volume.
