Glossary
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
GLOSSARY
The part inside a page printer on which the image is created before it is
transferred to the paper.
Postscript
See Page description language.
Precharger wire
A fine wire in the printer's process cartridge that imparts an electrical
charge to the photoconductive drum. The charge makes the drum
sensitive to light.
Printable area
The area of the physical page in which the printer is able to print. Page
printers have a nonprint margin, typically about .2 inch (5 mm) wide, at
each edge of the paper. The printable area is the space within these
margins. See also Margin.
