Genuine OEM HP OfficeJet R40 Ink and Supplies

The OfficeJet R40's HP 45/23 combo contains one black cartridge and one tri-color cartridge. That's different from the HP 45 twin pack, which contains two black cartridges and no color ink. Choose the combo for both inks, or the twin when you want another black cartridge in reserve.

Toner Buzz carries genuine HP 45 black and HP 23 tri-color ink, individually and in those packs. A single 23 cartridge covers the printer's cyan, magenta, and yellow inks together, so the black-and-color combo covers both cartridge types.
