Review on Kingjet Compatible Ink Cartridge Replacement for HP 970XL 970: High-Quality Printer Ink for Officejet Pro X576dw, X451dn, X451dw, X476dw, X476dn, X551dw - 1 Black Cartridge by Richard Miller

Bought because the printer's keyboard failed and I had a lot of colored ink left. But other than that, the printer works fine while the job is running from the computer. Aside from a continuous error message (non-HP product), it works fine until it stops working. Remove the cartridge, put it back and everything will work fine until it happens again tomorrow. Admittedly this printer is on the way out but that's not the problem I was expecting. I would try this product again on a new printer.
