HP 78A Toner: Common Questions

What is the difference between the HP 78A sizes?

78A prints about 2,100 pages and the jumbo version about 3,000 in the same cartridge body. HP's cartridges have the drum built in, so there is no separate drum to buy.

Which printers use HP 78A toner?

HP LaserJet Pro P1566, P1606dn, M1536dnf. Our Find Ink by Printer page has a guide for each model.

Will compatible HP 78A toner work in my printer?

Yes. Our cartridges are new, not refilled, and install like an original. Keep automatic firmware updates off so a future HP update can't block third-party toner. If a cartridge from us isn't recognized, contact us and we'll replace or refund it under our 1-year guarantee.

Standard or jumbo: which should I buy?

Jumbo if you print regularly. It is the same cartridge body with more toner, so each printed page costs less. The standard 78A makes sense if you print only occasionally.
