Genuine OEM HP LaserJet Enterprise Flow MFP M528 z Toners
For the LaserJet Enterprise Flow MFP M528z, HP 89X is the high-yield alternative to standard-yield HP 89A. Its larger toner capacity means more pages from a single cartridge, which is useful when you want frequent printing to involve fewer toner changes.
Toner Buzz carries genuine HP 89A and 89X black cartridges for this printer. The 89A is the smaller-capacity option for lighter use; choose 89X if you want to leave more printing time between toner changes.
