Here's a neat little way to save in when printing: EcoFont.
It's a great idea: a font with small holes in it. Because of the holes, less ink is required.
At small sizes, like 12 points, the holes are barely noticeable. It's a tiny big gray, but not enough to make it hard to read.
Just download the font and install it to increase the life of your print cartridges.
