LaserJet M521dx
The HP LaserJet M521dx is exactly what its late-2000s badge suggests: a mono single-function printer made for everyday office document printing. What keeps the LaserJet M521dx relevant is everyday office document printing: unglamorous, essential, and exactly what offices need.
One practical upside of the LaserJet M521dx: its HP 55A/55X cartridges (CE255A) are shared with 39 other models, so you're never hunting for something obscure. We stock both quality-compatible HP 55A/55X cartridges and genuine OEM CE255A supplies for the LaserJet M521dx, so you can match your budget to your print volume.
