of the paper are at the top and bottom is called portrait orientation.

Example:
Page description language
A set of codes that describe the placement of text and graphics on a
page. Page Control Language (PCL), the language used by HP
LaserJet printers, and Postscript are examples of page description
languages.
Page protect
A printer feature that reserves a block of printer memory exclusively
for text and graphics data. Page protect prevents memory overflow
errors when printing very dense text or complex graphics. However,
page protect also reduces the amount of printer memory available for
downloadable fonts.
Parallel interface
A connection between the computer and printer in which data is
transferred simultaneously through multiple wires. A parallel
interface is faster than a serial interface, but the distance over which
it can send data is limited. The Centronics interface is a type of
parallel interface. See also Serial interface.
Photoconductive drum
The part inside a page printer on which the image is created before it
is transferred to the paper.
