Genuine OEM HP LaserJet Enterprise MFP M528f Toners
The HP 89-series cartridges used by the LaserJet Enterprise MFP M528f differ in how much toner they hold. Standard-yield 89A is the smaller-capacity choice; high-yield 89X extends the number of pages you can print before changing cartridges.
Toner Buzz carries genuine HP 89A and 89X black toner for the M528f. For occasional printing, choose 89A. If your printer handles frequent documents, 89X gives you a longer run between toner changes.
