I’ve no idea whether this is real or not, but at least it can save you some inks. When you save inks, you also save papers, and additionally you also get good looking documents. Printfriendly will help you to print the parts of a webpage which are important to you only.
It is very easy to use, simply add an URL, press print preview and get a printer-friendly version of a web page.
I know this may took time, but I think it is something that very useful. Your web page is then format-able, and you can see on the screen what you are going to print, instead printing lot of unwanted empty tables, color bars and page of advertisements.
Tips: You will be able to save the minimal version of the page as PDF before you print it using your printer.
