HP Ink Cartridge Refill Kits are an alternative to HP Instant Ink
If you use HP’s instant ink subscription service where you pay a monthly fee for ink delivered to your door, have you considered using ink refill kits as another option?

By a two step method, you can quickly and easily refill your existing HP cartridge (not the HP Instant ink programmed cartridge) to replenish your ink for your H.P printer.
