That same problem exist if you happen to have purchased an HP cartridge on Ebay or elsewhere that is an HP "Instant Ink" product. The HP "Instant Ink" program delivers instant ink but the cartridges are not for sale or resale. So, if you end up with extra cartridges that you will never use too bad. The printer will tell you that it is not a genuine HP cartridge which is a boldface lie because it is precisely a genuine HP cartridge.
