It's true!  According to research by the printer.com blog, all users (business and personal) can save up to $80 per year per printer simply by changing the default font used when printing documents.

Besides having a cool name, Century Gothic covers the average piece of paper with a mere level of 3.45% total ink coverage.  By comparison, the most commonly-used font, Arial, averages 4.9% coverage.  Depending on how thick the font you use is, you can be using up to 60% more toner per page you print than you need to.  (Think of that $80 a year as a free month's worth of Starbucks -- remembering to use your own travel coffee mug, of course.)

A few other money & planet-saving tips (tips are in Century Gothic font):
1.  Set Century Gothic as your default font
2.  Use a smaller font size so you can put more text on a page, thus using less paper (The average US office worker goes through 10,000 sheets of copy paper a year.)
3.  Use recycled paper (buy paper with a higher post-consumer recycled content AND also print on the opposite side of unneeded documents or scrap papers)
4.  Instead of printing 2 sheets, print 1 sheet that is 2-sided
5.   Recycle toner and ink cartridges and buy remanufactured ones.  According to Office Depot, each remanufactured toner cartridge "keeps approximately 2.5 pounds of metal and plastic out of landfills . . . and conserves about a half-gallon of oil." 
6.  Think before your print!
