HP 81X High Yield Black Original LaserJet Toner Cartridge CF281X   
 
Looking for a toner that doesn’t make you babysit the printer every other week? This 81X is the high yield version – so yeah, way more pages, way less hassle. It gives sharp, crisp black prints, perfect for offices that actually print a lot (invoices, statements, contracts… all that boring grown-up paperwork).
It’s an original HP cartridge, so no drama with compatibility and no cheap streaks/smudges. Just reliable print quality and solid performance like it’s supposed to be.
Yield: approx. 25,000 pages (on standard ISO page coverage)
Color: Black
Works with: HP LaserJet Enterprise M605 / M606 series & M630 MFP series
In short – if you hate changing toner every few days, go for this. It lasts.
