Genuine OEM HP DeskJet 880 C Ink and Supplies
The 880C's HP 45 twin pack provides a spare black cartridge, but it doesn't include HP 23 color ink. For a black-and-color purchase, the HP 45/23 combo contains one of each cartridge type instead.
Toner Buzz carries genuine HP 45 black and HP 23 tri-color ink individually, along with both packs. The tri-color cartridge holds cyan, magenta and yellow together, making a single HP 23 the choice when only color ink is needed.
