A:AnswerI would not buy more ink. If the printhead is bad new ink will not help. You can try some troubleshooting options at this link. https://support.hp.com/us-en/document/c04100778 If none of those troubleshooting options work. You will need to get a new printer.
A:AnswerEvery HP ink cartridge has a warranty expiration date, which is not an expiration date for the cartridge. It is always 2 years from the date of manufacture (which will vary, based on the timing of your order and inventory factors).
