HOW MUCH INK IS IN YOUR CARTRIDGE?
Cartridges are getting SMALLER. The new HP 302/304 has just 2ml of ink, and the new 302XL/304XL holds less ink than the old 302XL did.
Our chart below shows the ml and page yields for the most popular HP cartridges, next to our prefilled cartridges.
MORE INK FOR YOUR MONEY
Our prefilled XL cartridges hold 18-20ml of black and 18ml of colour, up to 4½ times more ink than an original XL.
WHAT'S INSIDE AN ORIGINAL HP CARTRIDGE?
We cut some original HP cartridges open (top photo) - look how small the sponges are! Most of the cartridge is empty space.
AND INSIDE OUR PREFILLED CARTRIDGES
In our prefills (bottom photo) a BIGGER sponge fills the cartridge, so it holds much more ink. And they all show ink levels, just like the originals.
