Check the color cartridge separately
HP's user guide identifies HP 78 tri-color cartridges in the C6578 series. Confirm the full suffix and capacity designation on the individual listing against your printer's requirements. HP 23 is a different reference and should not be substituted simply because a combo pack also contains HP 45 black. This page's checked product link is for black ink only; it does not establish compatibility for every color or combo listing in the collection.
Before you order
- Confirm the exact model is HP DeskJet 6122.
- Match the full reference on your existing cartridge or printer documentation.
- Check whether the listing contains black ink only or a black-and-color combination.
- Review quantity, condition, packaging, and individual product compatibility.
- Do not assume a two-pack has a guaranteed combined page yield.
