LaserJet Pro M521DX
A late-2000s mono single-function printer, the LaserJet Pro M521DX reflects an era when printers were bought for durability first and features second. The LaserJet Pro M521DX treats everyday office document printing as its whole job description, and does it well.
Cartridge-wise, the LaserJet Pro M521DX belongs to the HP 55A/55X family (CE255A), which means 39 other models use the same supplies. Pair the LaserJet Pro M521DX with genuine OEM CE255A cartridges for maximum peace of mind, or stretch your budget with compatible HP 55A/55X cartridges that print just as sharp.

Frequently Asked Questions
Does the LaserJet Pro M521DX take the same toner as other LaserJet printers?
Only cartridges coded CE255A or CE255X fit the LaserJet Pro M521DX — look-alike HP cartridges made for other families won't fit or be recognized. Match the code on your current cartridge when ordering for the LaserJet Pro M521DX.
What should I do when the LaserJet Pro M521DX shows a toner-low message?
Treat it as an early heads-up on the LaserJet Pro M521DX — you can keep printing while a replacement CE255A or CE255X is on its way. Swap the cartridge in the LaserJet Pro M521DX once pages start fading, not the moment the message appears.
Should I buy genuine or compatible toner for the LaserJet Pro M521DX?
Both work in the LaserJet Pro M521DX: genuine cartridges come from HP, while compatible cartridges are third-party versions built for the same printer. Many LaserJet Pro M521DX owners choose based on budget and print volume without issue.
