If you do figure out how to print real money - please let me know! I've printed pretend money in the past but can't locate the site. I did find this one but you have to sign in. It does offer a free limited membership and I am not sure what they covers. It might be worth checking it out: http://www.moneyinstructor.com/play.asp
Just make one on Microsoft Word and then you can make it look like you want it to....just use the drawing tools, add clipart, add dollar amount and what you want to call your money with Wordart.
