I have a rather old printer/copier and tried to purchase the refilled ink. Wouldn't quite fit and wouldn't print. Returned for credit to another company and bought the original HP from Staples. Fits and works perfectly like it always has. Pays to buy what was made for my printer.
This is the second or third delivery from Staples during the pandemic where one or more ink cartridges upon being installed registered a "counterfeit" error on the printer screen.
