If you have an iPhone, you've probably taken tons of photos with the built-in camera. Sharing photos online is really great, but you can do so much more! ePrint is an app that lets you print photos directly from your iPhone or iTouch using a Wi-Fi enabled printer and no computer at all.
Epson provides this video tutorial on how to print photos wirelessly with iPhone or iPod Touch to a Wi-Fi enabled printer, such as the Epson Artisan or WorkForce all-in-one printers, using the ePrint app.
To do this, you will need to buy and download the ePrint app on your iPhone or iTouch, have a Wi-Fi enabled computer, and know your printer IP address.
