My HP Officejet 8710 signals that only the Cyan and Yellow cartridges are empty, but the blue and black still have some ink. It currently refuses to print, even on Grayscale.I know that monochrome printing can require color cartridges too (duplicate question), but loathe to buy a monochrome printer or color ink cartridges. So how can I compel the printer to print, regardless of the print quality? via /r/DIY https://ift.tt/2AWzUXl
