First, a document is not printed as it is created, but as you enter text, your word processor displays it on the screen. Your document can be printed later. This allows you make many changes to your document without using even one piece of paper.

Second, you can easily edit or modify your text. This includes moving text around in your document, deleting, inserting, and replacing text. Since only the parts that need editing are retyped, you are spared retyping the entire document. This will decrease the amount of time you spend retyping, which will increase your opportunity to improve and refine the quality of your text.
