It's affordable to print with an Epson EcoTank. With a bottle of black 102 EcoTank ink, you can print up to 7500 pages. With the color ink bottles, you can print about 6000 pages. You can easily fill the ink tank of your Epson EcoTank with these bottles. The special design of the nozzles of the bottle ensure you only put the right color in the ink tank. This way, you won't mix colors by accident. Before you buy the ink, make sure to check which ink bottles are made for your specific Epson ExoTank printer.
