Hello, my name is Syd and I work for Epson America.
For AirPrint to work correctly please verify the following procedures have been done.
1. The printer is connected to the same wireless network as your iPhone and computer.
2. On your computer, run Download Navigator. This should have been installed during initial setup in the Epson folder inside your Applications folder.
3. Run all firmware updates. It is necessary to have the newest firmware for AirPrint to be enabled on your printer.
4. Restart the printer.
5. On your IOS device when printing, click the appropriate icon (depending on app) and select printer. Please wait if the printer name does not show immediately, as interference may cause a delay in the name appearing.
6. Tap print.
If you have done this already or would like a walk through of the procedure, please call Epson tech support at 562-276-4382 and they would be happy to assist.
