Genuine OEM HP DeskJet 990 Cxi Ink and Supplies

The HP DeskJet 990 Cxi uses HP 45 for black documents and an HP 78 tri-color cartridge for color. The HP 78XL is the high-yield color format, giving you a clear choice on the color side.

Genuine HP 45 black ink and HP 78 or HP 78XL tri-color ink for the DeskJet 990 Cxi are carried by Toner Buzz. Order the cartridge that needs changing, or choose the HP 45/78 pack when both black and color are due.
