The high capacity HP 730 grey contains more than twice as much ink as the standard capacity Hewlett Packard offering, with a full 300ml of ink. As well as offering a much lower cost per page, the HP P2V69A also results in less maintenance to your large format printer, increasing productivity.Of course, you can expect the same great Hewlett Packard print quality from the 730 grey high capacity cartridge, as you experienced with those that came with the printer. There is no more economic genuine grey cartridge for the HP Designjet T1700dr than this P2V69A and we whole-heartedly recommend it.
