I never print instructions unless (rarely) there is a part or two on the instruction page.
I always view on the computer. That being said, I wish folks would do instruction pages Landscape instead of Portrait. If I need the instructions larger, just change the view, but I don't like to scroll up and down all the time.
I was going to say that I couldn't remember whose instructions I really liked, but then I remembered. Chris Roe of Genet Models does excellent instructions. If there was one thing I wish he would do different, it would be showing the tabs in his diagrams, but Chris does very nice instructions,
