Genuine OEM HP OfficeJet 6815 Ink and Supplies

The HP OfficeJet 6815 uses HP 934 black ink and separate HP 935 color cartridges. The combined ink set pairs high-yield HP 934XL black with standard-yield HP 935 cyan, magenta and yellow, so the whole set should not be treated as high-yield.

Toner Buzz carries genuine HP ink for the OfficeJet 6815, with individual 934XL black and a combined black-and-color set. Choose black alone when that is all you need, or the mixed-capacity set for all four colors.
