Primo PDF Informative - A free tool for creating PDFs from any computer
I suggest that anybody who does lots of transactions on the internet download the free copy of Primo PDF (www.primopdf.com). Once you download this free tool, Primo PDF will appear like a regular printer when you select File>Print.
The printing steps are very similar to normal printer, but the end result is a PDF that you can save to your computer like in "My Documents" or desktop. The PDFs are created just like they would look on paper, and you can print them out later if need be.
I use it to save a copy of any important info that might come in handy later like fine print, bill pay confirmations, travel bookings or invoices. I have it on my personal and work laptops, and I will often email a document to myself to print later when I am networked to a real printer.
Since I downloaded Primo PDF I have cut down on my paper usage by probably 90% because I really never needed most of the stuff I was printing anyway, and it is much more useful to have an electronic copy of most documents anyway.
