Ink cartridges (or toner) could last longer. As a result, the company SPRANQ developed an ecofriendly font. Here is the link to download the font as a TTF. It uses 20% less ink when you print. The Ecofont was created by omitting parts of a letter using circles. At the shown size, this obviously is not as adaptable, but at a regular font size it is actually very usable. The only downfall is that it is only in uppercase. Naturally, the results vary depending on your software and the quality of your screen.
