Nearly all of us have frowned at an errant page printed off a website with nothing but the URL footer or an advertising graphic. GreenPrint (currently Windows only) offers an easy way to suppress unnecessary pages and graphics. It serves as a simple print-to-PDF portal and also tracks the paper and money saved. Most GreenPrint customers find themselves saving upward of $90 a year. With a single sheet of paper sometimes taking more than a soda can's worth of water to produce, the effects on the environment are just as impressive.
A premium version is available for purchase which supports GreenPrint in the workplace and offers advanced customer support. Sales are also green: GreenPrint is a member of 1% For The Planet.
