LaserJet Pro M521
HP introduced the LaserJet Pro M521 in the late-2000s as a mono single-function printer for everyday office document printing, and plenty of them are still on the job. If your workload is everyday office document printing, the LaserJet Pro M521 is the kind of printer that just keeps showing up.
The LaserJet Pro M521 uses HP 55A/55X cartridges, anchored by the CE255A — one of the most widely stocked HP cartridges of its generation. For the LaserJet Pro M521, we carry genuine HP CE255A cartridges alongside compatible HP 55A/55X options that cost less to run.

Frequently Asked Questions
Where do I find the toner code for the LaserJet Pro M521 before ordering?
Pull the installed cartridge and read the code printed on its side — the LaserJet Pro M521 takes the CE255A or the high-yield CE255X. Ordering by that exact code for the LaserJet Pro M521 is the simplest way to avoid a mismatch.
Why is my LaserJet Pro M521 printing blank pages?
Blank pages from the LaserJet Pro M521 usually mean the cartridge is empty or the protective seal was never removed from a new one. Check the supply level, and if you just installed a cartridge in the LaserJet Pro M521, remove it and pull the sealing tape completely.
Should I buy genuine or compatible toner for the LaserJet Pro M521?
Both work in the LaserJet Pro M521: genuine cartridges come from HP, while compatible cartridges are third-party versions built for the same printer. Many LaserJet Pro M521 owners choose based on budget and print volume without issue.
