Refilling your HP 91 wide format ink cartridges is easy and affordable with this InkOwl refill kit! This kit comes supplied with the required syringes and needles to correctly fill the cartridges, and includes easy, detailed instructions which explain the whole process. Refilling is extremely cost-effective because it is possible to fill the cartridges with as much or as little ink as required. With our American-made inks, there is no need to compromise on image quality or longevity!

NOTE: Even after refilling, your printer will continue to indicate your cartridge as empty. Our instructions will explain how to bypass this error and continue printing. However, it will be your responsibility to monitor the cartridges regularly and refill them well in advance of them running dry.
