Don't know which cartridge you need for your printer??
The following tables show all compatible HP Inkjet Carts for HP DeskJet and HP DeskWriter s.

NB:

1. Cartridges are given in this order: where applicable some machines will only take some of these: Black Cartridge Colour Cartridge Tri-colour Cartridge Other Cart.
2. Where Zones appear next to your , this  uses regionalized ink supplies, so which inkjet print Carts you can use in your  depends on where you are in the world. ZONE 2 is UK
3. As theres are so many I've created 2 guides A and B if you can't see your printer in 1 list it will be in the other!!
