Genuine OEM HP DeskJet 990 c Ink and Supplies

The HP DeskJet 990 c uses two separate ink cartridges: HP 45 for black and HP 78 for tri-color. The high-yield HP 78XL is the other color option for this setup.

Toner Buzz carries genuine HP 45 black cartridges, HP 78 tri-color cartridges, and HP 78XL tri-color cartridges for the DeskJet 990 c. Buy one supply when that is all you need, or choose the HP 45/78 pack for black and color together.
