First, reconnect your printer to the router by using these steps:Press the Setup button on the printer. Select Network Settings and press the OK button.
You see this screen:
Select Wireless LAN Setup and follow the steps to re-enter your network information into the printer and make sure the printer is connected there.
Then, lets reinstall the driver on your Windows 7 computer:

Click the Windows Start button > Control Panel > Uninstall a program > Remove any Epson printer programs/drivers there too
Restart your pc, then return to this page > Insert the setup cd that came with the printer and reinstall the printer drivers (Let me know if you don't have the cd, that's ok) > Make sure to install it as a network/wireless printer
