Review on 🖨 HP 901 ink cartridges for OfficeJet 4500, J4500, J4680 | CZ075FN Black Ink by Evan Zurlo

I bought this pack of 2 HP 901 black ink cartridges thinking they were genuine HP products; when i tried to install it on my printer it didn't align properly; The printer did not appear to "find" the cartridge. I currently have it on my printer, but every time I print a document I have to go to the "Properties" section of the print pop-up menu and reset it to "Print in Grayscale" or else it gets a weird "reddish - Brown colour. I'll probably end up buying my HP 901 black ink from Staples, where I know I'm getting an original HP cartridge.
