Here's an idea that's rather interesting - a font that's built with holes in it to use less black ink. The makers of this say that you'll be able to save up to 20% of your printing costs - oh and it looks better when printed - those little holes aren't nearly so noticable.

Here are my solutions to save when printing. Depending on usage of printed material, these points may be relevant or not:

• I print both sides of paper
• two or four document pages on same paper page
• low quality printing
• avoid printing as much as possible: I don't like piles of papers that will eventually finish their lives in trash can. Most of the time I work on electronic documents.
• I use a monochrome laser printer: Cost per page is very cheap compared to ink jet printers

• Don't throw away papers that are printed only on a single side - use them later, the opportunity will come.
• In my office, I often lock away the papers - this encourages other people to print less as well.
• Study the software that came with your printer, so that the default printing method (when you're in a rush) - will be duplex and monochrome.
• Buy and use recycled paper. This also promotes the recycling economy.
• Kids just love to do stuff with used papers and paste - find a local kindergarten/grandma, and ask if they need some :)
• I read PDFs off my Kindle. A great paper-replacement technology.
• Develop the habit of thinking that waste=something's-wrong. Every time I have to "throw away" stuff, I know that there is no "away". This encourages me to produce less waste.
• Hugh, and a friend just sent me this: A printer that uses no consumables. Maybe we'll soon see these around :)
