Genuine OEM HP Color Copier 170 Ink and Supplies
For the Color Copier 170, buying an HP 45 twin-pack adds another black cartridge; it doesn't add color ink. HP 23 is the separate tri-color supply. If your order needs both black and color, the HP 45/23 combo is the pack that includes both.
Toner Buzz carries genuine HP 45 black and HP 23 color ink for this copier. Individual cartridges suit an order for one ink supply, the HP 45 twin-pack gives you extra black cartridges, and the HP 45/23 combo groups black and color in one purchase.
