GLOSSARY
page orientation Direction in which data is printed on a page. Refer to landscape
page orientation and portrait page orientation.
page or side Refers to the side 1 or 2 of a sheet.
parallel interface A type of interface between a printer and its host in which data is
transmitted and received in bytes rather than bits. Used for local
printing over short distances (25 feet, 7.63 metres, or less).
parity The addition of a check bit to data information in order to verify
the accuracy of the information.
photoreceptor The photoreceptor or print drum is found in the replaceable print
cartridge and is used to form letter or line images on documents.
pixel Abbreviation for “picture element.” The smallest unit of a
graphic image. An unmagnified pixel is 1/300 inch (.08 mm). A
pixel is also referred to as a dot or a spot. It is the smallest
addressable point of a bit-mapped screen that can be
independently assigned colour and intensity.
portrait page orientation A page orientation in which the image runs parallel to the short
edge of the paper. Portrait refers to printing across the width of
a page (letter style). This is the opposite of landscape
orientation which is printing across the length of the page. The
term “portrait” is derived from portraits of people, which are
usually vertical in format.
print cartridge The print (photoreceptor) cartridge contains a photosensitive
“print drum” used in the printing process. The cartridge is
disposable.
print density Print density refers to the relative darkness of print on the page.
Very dense print appears totally black. Less dense print looks
lighter, and solid filled areas may not be totally black. You can
adjust print density in the printer.
