Did you know that Microsoft Word enables you to print documents double-sided? This facility can also be used for printing long pdf documents. Simply follow the following steps:
Go to print and click on the scroll down arrow in the box where it says 'print - all pages in range'. First click on 'odd pages' and press OK. Once these pages have been printed you have to turn the pages around and reload them into the printer, (and figuring out the correct direction is the hardest bit!) Then you simply choose 'even pages' from the same box, and , as if by magic, you have your double-sided document perfectly printed and you can revel in the thought of the forests you will save by doing this on a regular basis.
