The Canon PGI-270 and CLI-270 Ink Tank combo pack is an indispensable accessory that gives your prints a better color fastness and a wide color gamut. The pack also includes a stack of 50 PP-201 printing sheets. The ink tanks offer you free access to premium content through the Creative Park Premium software from Canon. The cartridges feature an LED light, which informs you not only about an empty tank, but also about whether the tank is properly installed.
