HP company added an encrypt counting chip to the Ink Cartridge of its HP500, HP500PS, HP800, HP800PS series printer, so its cartridge is disposable and only dye inks produced by HP company can be employed. Therefore, there is no use for other compatible dye inks. The original prices for dye inks produced by HP Company are more than ten times dearer than dye inks of other brands. Our company developed this external-hanging style electronic card in order that users could have broader choices of better dye inks whose performances are as good and prices much lower.
