Product: HP Photosmart A646 Compact Photo Printer
I bought a used Photosmart a646, it has an ink cartridge in it already but when I power it on it says that is not the correct cartridge so I need to know what the proper number cartridge is. It has a 110 in it and when I search the hp website it suggests like 20 different cartridges and that obviously doesn't tell me which one I need. Any help would be greatly appreciated!
