Product Type Description:

Compatible, or generic, ink cartridges are ink cartridges made by a third party manufacturer. They are designed to work just as well as the original cartridges, and print the same number of pages, at a lower cost. They will not void your machine warranty (although printer manufacturers may refuse to repair a printer fault caused by using compatible cartridges).

Printzone stocks only the best quality compatible ink cartridges, and offer a money back guarantee or replacement if they are faulty. Our experience is that the compatible ink cartridges we sell are reliable and safe to use and can save you money if you are on a tight budget.
