Genuine OEM HP OfficeJet 8045 Ink and Supplies
The HP OfficeJet 8045 takes HP 62 black and tri-color ink, with higher-yield HP 62XL options. The mixed black-and-color combo increases black capacity while keeping color at standard yield, so it is not the same as choosing XL for both inks.
Toner Buzz carries genuine HP 62 and HP 62XL cartridges for the 8045 as singles and combined packs. Select the mixed combo for extra black capacity with standard color; order individual cartridges if you need XL color, a different combination or just one ink.
