There isn't anything in Settings about printers. Wireless printers are "discovered" automatically on the local network.
However, that Epson printer doesn't support Airprint. See iOS: AirPrint 101 - Apple Support for a list of supported printers.
You may be able to use the Epson printing App in the App Store or one of the other printing Apps, e.g. Printopia, etc.
