If you're anything like me, you do a lot of printing and photocopying each day for class. When I started teaching, I brought my own printer to hook up to my school computer. I used it to print stuff for handouts, tests, and progress reports on demand. I had to constantly replace cartridges on my own, even when I usually printed in "draft" mode to save ink. Even when I had a school-issued printer in recent years, ink and toner replacements were extremely hard to come by. Then and now, saving ink is the rule.
Now there's some help on the ink-saving front: Ecofont. This free font saves ink by inserting little circles into the letters, using less ink while still keeping things legible. At home, this is a great way to save ink when printing everyday stuff like directions or similar information. I plan to test it in the classroom as well, to see whether my students will even notice. More than likely, they'll comment on how I should fix the copier because it will appear to be running out of ink as far as they can tell. That's a chance I'm willing to take.
