HP have two sizes of ink cartridges. HP 304 black and colour standard capacity ink cartridges and HP 304XL black and colour high capacity ink cartridges. The ink cartridges in the HP 304XL have larger sponges so they can hold more ink and print more pages. Original HP 304XL ink cartridges effectively produce twice as many prints than the standard capacity cartridges at a reduced price per page.
- HP 304 Black - 3.5ml
- HP 304 Colour - 4ml
- HP 304XL Black - 8.5ml
- HP 304XL Colour - 8ml
Unfortunately if you are buying HP 304XL remanufactured or refilled ink cartridges many sellers on eBay and Amazon are dishonest and are using standard capacity ink cartridges and putting an XL sticker over the top in the hope customers won't notice. However we only sell Ink Jungle refilled ink cartridges which always use XL cartridges with the larger sponges and have produced some images below to help consumers how to tell the difference between a fake 304XL and a real 304XL refilled ink cartridge.
