Bookmark (favorite mark) a website instead of printing. It is the fastest and easiest way to save a website for future reference. Diigo is a great social networking tool for saving sites, sharing and making notations that will be saved.
If you need a copy for reference try printing it to a .pdf document instead of printing to paper. There are several free .pdf creator sites. Once, downloaded instead of selecting your printer to print to select .pdf as your printer and create a .pdf document copy. PDF Creator can be found for free at http://sourceforge.net/projects/pdfcreator.
Instead of creating notes on paper - create notes using Evernote and access from anywhere.
