The first word processors were basically computerized typewriters, which did little more than place characters on a screen, which could then be printed by a printer.Modern word processing programs, however,include features to customize the style of the text,change the page formatting and may be able to add headers,footers, and page numbers to each page. Some may also include a "Word Count" option, which counts the words and characters within a document.
