If you need to buy ink for your printer I recommend you buy it online and that you buy original ink. If you have a HP printer make sure you buy HP ink and not some cheap no name brand.

Same goes for Epson printers and Epson ink. It is important to keep the printer ink fresh and buy from reputable source that doesn’t need to stock their ink for too long. It the ink is stored for too long it might get dry. Also once you put it in your printer it’s a good idea to keep your printer on so that it can perform self clean every once in a while.
