ecoPrint2 Pro installs itself as another printer and works to reduce the amount of paper and ink you use. To use it, just install it and print your document as you normally would, only this time select ecoPrint instead of your regular printer.
After opening the wizard, you can set up different options like adding page numbers or even a customizable watermark (for confidential documents or drafts).
You can also access statistics from the menu to check the amount of paper and ink you've saved in a given period.
The trial version only lets you print 50 times.
