There are lots of ways to save money on pricey printer consumables.
You can configure your print driver to output two pages on a single sheet of paper. You can enable "draft" mode to use less ink. And, of course, you can bypass printing altogether and generate PDFs.
Then there's Ecofont, a free typeface that promises to consume up to 20 percent less ink.
Available for Windows, Mac, and Linux systems, Ecofont closely resembles your basic Arial, but with one key difference: holes. Each letter has loads of little holes punched out of it, meaning it requires less ink to print.
But as you can see in the example, Ecofont is still plenty readable. So why not use it for all your everyday print jobs?
I know, I know, there are lots of outline-style fonts that would accomplish more or less the same thing. But not many of them look just like Arial--or have the environmentally conscious "Eco" prefix. That's how you know it's "green."
Anyway, it's been about a million years since I installed a new font. If you need a refresher course like I did, you can find help on the Ecofont download page.
