that is sent to the printer from the computer (such as downloaded fonts) is stored
in memory temporarily. See also

is either portrait, where the length of the page is longer than its width, or
landscape, where the width is longer than its length.

to the bottom of the lowest. A point is a typographic unit of measure equivalent

printing is oriented sideways on the page). This is the standard orientation for
printing letters or documents.
