One of the first things I do when setting up a new computer is to set one of my virtual printers (OneNote Send-To, XPS Document Writer, Bluebeam PDF, etc) as the default printer. By setting one of those as my default printer, any time I press the print button, they are all stored electronically rather than on paper. Paper is still an option, but I have to choose to print to paper, rather than the other way around.
That is one way to 1) save money, 2) save space, and 3) save trees.
