Page orientation is the direction in which a document is displayed or printed. The two basic types of page orientation are portrait (vertical) and landscape (horizontal). Most monitors have a landscape display, while most documents are printed in portrait mode.
Before printing a document, you may be able to change the page orientation by selecting "Page Setup..." from the program's File menu. The default orientation is typically portrait, but you can change it to landscape if you want the width to be longer than the height. This may be useful for printing signs, cards, or other documents that require a wide display.
