Genuine OEM HP Deskjet 3637 Ink and Supplies

The HP Deskjet 3637 has HP 63 and HP 63XL choices for both black and tri-color ink. XL means more pages from that cartridge, not that you must choose XL for both inks; you can keep standard color while increasing black capacity.

Toner Buzz carries genuine HP 63-family cartridges for the 3637, with individual capacity choices and black-and-color packs. Choose the singles when you want to decide each capacity separately, or compare the contents of a combined pack before ordering both inks together.
