Genuine OEM HP OfficeJet G55 Ink and Supplies

The HP OfficeJet G55 uses an HP 45 black cartridge and an HP 78 tri-color cartridge. If you need the high-yield color format, HP 78XL is the matching option for this model.

Toner Buzz carries genuine HP 45 black cartridges plus HP 78 and HP 78XL tri-color cartridges for the OfficeJet G55. Pick black or color separately as needed, or choose the HP 45/78 pack to order the two together.
