Genuine OEM HP PhotoSmart C4798 Ink and Supplies
The HP PhotoSmart C4798 takes HP 60 black and tri-color cartridges, and HP 60XL offers more pages from either one. A higher-yield cartridge and a two-pack are different choices: one changes cartridge capacity, the other adds a spare.
Toner Buzz carries genuine HP 60 and HP 60XL supplies for the C4798. Along with singles, there are same-color packs and black-and-color packs, so you can order one ink type or cover both together.
