Regarding your "old" Epson, don't kick yourself too much -- software and hardware is "old" the second you install it. (The business development folks aren't dumb. Their profit-sharing comes from the sales divisions. No sales, no profit.)
Go to
www.epson.com and try to locate a downloadable (usually free) upgrade and/or driver for your current hardware. Epson is very, very good. You should find what you want there.
That will work most often, but changes are occurring so often and so quickly, depending on your computer platform (PC vs Mac, new vs old platforms), that sometimes you can't keep up without spending more money. It's very hard, but the money's usually well spent. No company ever goes back to the old way, so don't wait for it to happen -- especially in computers, where nobody ever even goes back to yesterday.
