IKONG Compatible HP CF279A 79A Toner Cartridges, 2 Black for HP Laserjet Pro M12w M12a M12 M26nw M26a M26 Printer - 1,000 Pages per CF279A 79A Toner Cartridge

Poor print quality and the printer knows it’s not a real cartridge

Not a good buy. After two weeks need to change to a new one. I have used other brands and not experience this.
