Genuine OEM HP OfficeJet K80 xi Ink and Supplies

The HP OfficeJet K80 xi separates HP 45 black ink from HP 78 tri-color ink. The color cartridge comes in HP 78 and high-yield HP 78XL formats, so that choice does not affect the black supply.

For the OfficeJet K80 xi, Toner Buzz carries genuine HP 45 black cartridges and both HP 78 color options. Choose only the cartridge you need, or the HP 45/78 combination pack when it makes sense to order black and color together.
