A:Answer Thank you for the question. HP ink cartridges are not refillable. One good reason why is because we cannot attest to the quality of the refilled ink. It should be noted that non-genuine HP ink may or may not work in your printer. Or it may work once, but not again. It will likely change the quality of your print output and eventually damage the printer. If cost savings is your goal, the Instant Ink program may be helpful. Register your printer, choose a print plan, and ink will be delivered before you run out! Get information at https://www.hp.com/us-en/shop/cv/instantink.
