While looking at Yahoo! Finance online earlier today, I spied a story from Forbes Magazine suggesting that we print our paper money at home. We can do that with stamps at sites like Stamps.com or Zazzle.com, even with our own supplied images — so why not with paper money?

The article, titled "The New Green," by Yale professors Ian Ayres and Barry Nalebuff, suggests that the same scanners that read prices in most stores could identify our home-printed money as well.

My home printer is broken so I currently do my printing at the public library — cost five cents per page for B&W, 25 cents each for color — so this plan could get expensive for me.
