Genuine OEM HP Deskjet 3634 Ink and Supplies

Black and tri-color are the two HP 63 ink positions in the DeskJet 3634. Moving one position to HP 63XL does not require changing the other, so the larger cartridge can be used only where it makes sense for your printing.

Toner Buzz carries genuine HP 63 cartridges individually and in black-and-color combinations. Start with the position that needs ink, then compare HP 63 and HP 63XL for that slot before considering a paired pack.
