Our remanufactured HP 935XL magenta ink cartridges have been designed to offer the same impressive 825 page yield as the Hewlett Packard original. In additional to this our compatible Hewlett Packard C2P25AE cartridges are also compatible with all the same printers, including the HP Officejet Pro 6230. Great care has been taken to produce an alternative to the Hewlett Packard C2P25AE that offers comparable print quality. This has been achieved by our chosen manufacturers creating their own patent free HP 935XL components that allows your printer to draw top quality ink from the cartridge as needed.
