Having developed thermal inkjet technology in 1979, Hewlett Packard released the first Deskjet printer 9 years later. With a staggeringly high price tag of $995, the printer was capable of producing a staggeringly low 2 pages per minute - a far worse value than the deal you got on your HP Deskjet 6840dt. But back in the late 1980s, HP´s new printer was the only single sheet desktop printer on the market. Fast forward a couple decades and you´ll see the HP Deskjet line has grown immensely, as the HP Deskjet 6840dt is one of hundreds of different HP Deskjet models.
SuperMediaStore carries original and remanufactured ink cartridges for many of our HP Deskjet printers. Our entire assortment of HP Deskjet ink cartridges designed for the HP Deskjet 6840dt is listed below.
