A dumb old laser printer that doesn't know I've been feeding it cheap aftermarket toner for more than 10 years. It's not a waste of paper if paper is the most efficient way to get my work done. Paper has a large viewport and unlimited battery life, while only weighing a fraction of most electronic alternatives. The only thing that a computer does better is searching, but this problem can be easily solved by having a PDF open on some other device as well. You don't have to choose one or the other.
