I always refill cartridge's of printer HP deskjet of any type because of efficiency. Usually we buy refill ink only Rp. 25,000 to Rp 35.000 that can be filled until 3 times refiling. While to buy new catridge we spent money about Rp. 130,000,- so that why I always doing this. For new catridge for HP deskjet usually can be refilled until 3 times and then must be change with new one.
