I'm forever trying to conserve the ink in my printer so that I don't spend a small fortune on cartridges. So, when I found Ecofont, I did a little private dance of joy. The font looks like a standard san serif (serifs are the little feet and hooks on individual letters in fonts like Times that don't appear on fonts like Arial and Helvetica) with holes poked in it.
It might sound strange, but it's perfectly readable at regular sizes and uses up to 20 percent less ink. The best part is that Ecofont is free to download and use, and it works on Macs and PCs according to the folks who designed it.
