Genuine OEM HP Deskjet 3940 Ink and Supplies

The HP Deskjet 3940 works with an HP 21 black cartridge and a separate HP 22 tri-color cartridge. You only need to match the cartridge to the black or color position that needs ink.

For this printer, Toner Buzz carries genuine HP 21 and HP 22 cartridges in single and two-pack formats. Choose a same-color pack when you want two of one cartridge, or the HP 21/22 pack when both positions need coverage.
