Hi Louis - if you check the link in my previous post concerning AirPrint compatible printers, your Epson XP-102 is not on the list, so this is not an option. About the only way to use that printer w/ the iPad is the way I print from my iPad to a Canon PIXMA printer, i.e. explained in the second paragraph using a program 'on my computer' called FingerPrint; a home Wi-Fi network is also a requirement.
Thus, the only way to use your current Epson printer w/ your iPad is to attach the printer to a computer (e.g. via USB), have a home Wi-Fi network, and also some software that will allow printing from the iPad - sorry.
In fact, even if you bought/exchanged your current printer model for one that is AirPrint compatible, both the new printer & your iPad would still need to be on the same Wi-Fi network according to this
Apple KB Article - maybe others who might have solved this printing issue will 'chime in' w/ more advice - good luck!
