Have the ET-16650 in the office. Very satisfied and cost-effective. Only the scanner is slow.
The ink (Epson® DURABrite®) seems to be different from the Pro for better images and more print formats (feed).
A comparison can be made on the Internet or on Epson's HP. There is a lot wrong here at Digitec.
