This sounds like a good idea. GreenPrint is a free printer driver which you can install and allows you to see what pages are a waste of paper (due to low volume of content), choose what pages not to print, remove text and even images from your document before you print it. There’s also an option to generate a pdf file of the document.
It’s so good that it actually demotivates and make you feel guilty if you still want to print rubbish such as a “I ate a potato today” message from your spouse/mates onto paper.
So, by the end of the month, do yourself a favor and generate a report to see how many papers and printing cost you have saved.
Here’s a video demo of how you can use the application.
