airport express printer problem

I have an airport express(2nd generation). I connect the printer with the airport express. However, when I print things, only the first page comes out and is stuck in the printer. The rest of the printing just shows "printing" (see the pic below) in my mac although the printer doesn't work anymore. I believe there is nothing wrong with my printer (Epson NX110) because when the printer was direclty pluged into my mac, it works perfectly. Hope someone can help me solve the problem. Thank you very much.
