Featuring 5-color inks, the Expression Premium ET-7700 wireless EcoTank all-in-one offers revolutionary cartridge-free printing with easy-to-fill, supersized ink tanks. It includes up to 2 years of ink in the box (1), equivalent to about 30 ink cartridge sets (2). That’s an incredible amount of ink — enough to print documents up to 9,000 pages, or thousands of 4" x 6" photos (3). Plus, it features Epson exclusive auto-stop ink bottles, with each color uniquely keyed for easy filling of each tank. And, you save up to 80 percent on ink with low-cost replacement bottles (4). The ET-7700 also prints up to 8.5" x 11" and includes paper and photo trays, plus built-in USB/card slots (5).
