Our Verdict
Epson EcoTank Photo ET-8550
Epson EcoTank ET-3850
The Epson EcoTank Photo ET-8550 and the Epson EcoTank ET-3850 are both all-in-one inkjet printers with a refillable ink tank. The main difference is that the ET-8550 is a photo printer but can also serve as an office printer, while the ET-3850 is an office printer that can print good-quality photos. If you want the best photo printing quality, the ET-8550 is a better choice as it has a wider color range and better color accuracy. Otherwise, the ET-3850 is better for everyday use. It has an automatic document feeder, which the ET-8550 lacks, and it's more cost-effective because it yields more prints, and its replacement ink is cheaper.
