"CleanPrint is an economically and ecologically friendly print tool that saves you paper, ink, and money while making your output look great. CleanPrint is activated by clicking the CleanPrint Browser Tool instead of the print button next to an article on a website. Before printing or saving content you can add a note, eliminate images, increase or decrease font size, and eliminate or grayscale text to save ink and paper."
