EPSON have a Linux driver for your printer model. You could use that one instead of the one in Ubuntu’s repository by following this procedure to install the dependencies (as they are not present in 16.04) and then installing the EPSON driver.
You should remove the existing printer first if you choose to use EPSON’s driver.
I must use their driver for my EPSON Stylus SX425W otherwise the Ubuntu driver prints the colours misaligned.
