Featuring 6 colour Claria inks, the wireless EcoTank all-in-one offers revolutionary cartridge-free printing with easy-to-fill, super-sized ink tanks. It includes up to 2 years of ink in the box, equivalent to about 185 individual cartridges. That's an incredible amount of ink - enough to print documents up to 5,500 pages black or 4,900 pages colour, or thousands of 4" x 6" photos. Plus, it features Epson® exclusive auto-stop ink bottles, with each colour uniquely keyed for easy filling of each tank. The ET-8550 also prints borderless up to A3 and includes paper and photo trays, plus built-in USB/card slots.
