Definitely HP, but from the picture is not very detailed: there are several models for this cartridges. Is it refillable: yes, but you will need to exchange the chip with one which is resettable.
thanks pharmacist - it doesnt sound like the OEM chip is resettable like the cli-8 cartridges w/ chip resetter? Do you have any links or info on where I can get new chips or a chip resetter?
