When your wide format HP printer tells you you need to replace the maintenance cartridge all you need to do is pop a new one in. This will keep the printer and print heads clean inside your printer and keep everything in good working order.

The cartridge is packaged in its own box so it can be stored for up to 12-months without its quality or performance being affected. Great if you want to order one in advance.

Don't forget our delivery is free and the HP 91 maintenance cartridge is covered by our 12-month performance guarantee.
