From an idea he had in middle school, the 14-year-old student Suvir Mirchandani did research using a software program to see if different fonts could lead to cost savings in ink. The answer was yes - the U.S. Federal Government could save $1.8 billion per year by switching to 12-point Garamond. Suvir said this would save 29% of ink costs, and published his results in the peer-reviewed Journal of Emerging Investigators. The Government Printing Office even said they would consider the printing suggestion!
