Lost driver disc for my new Epson 4400 series

Hello: Approximately 6 months ago I purchased Epson 4400 series and used driver with enclosed disc. Prior to my move to another location I removed the program (don't know why) packed up and did not unpack for another two months. I lost my disc to reinstall program. HELP i'M GOING CRAZY AND CANNOT AFFORD TO PAY FOR THE DISC. Can you get me a download FREE or for a moderate price?
