Genuine OEM HP Envy 4503 Ink and Supplies
Black-and-color packs for the HP Envy 4503 need to be compared cartridge by cartridge. HP 61XL black is higher-yield, but the HP 61 tri-color supplied with it is standard-yield; the XL label does not apply to both.
Toner Buzz carries genuine HP 61 standard black-and-color packs and mixed packs with XL black for the Envy 4503. The HP 61 tri-color two-pack offers a color-only choice and a spare for a future ink change.
