Xerox 4520 User Manual page 297

PCONSOLE A Novell utility that provides, for example, the
user with the ability to create and delete queues, or to display
a list of jobs currently in the print queue.
PDL Page Description Language. The set of rules that
describe a fully formatted page, independent of the device
used for printing. PCL and PostScript are examples of page
description languages.
Permanent fonts Also called permanently downloaded fonts.
These are fonts set up in an application so that when the
application is loaded, the fonts are downloaded to the
printer's memory. They then do not have to be downloaded
for every print job. Permanent fonts remain downloaded until
the printer is powered OFF.
Pitch The number of characters to the inch (10 pitch is 10
characters per inch). Typically thought of as "horizontal"
measurement.
Point Type height is traditionally measured in points. One
point is approximately 1/72 inch. Typically thought of as
"vertical" measurement.
Polling A method to control the data coming into the printer
through the I/O ports, which can include the parallel, serial,
and optional network ports. The printer looks at each port in
succession for incoming data, then transfers it to the print
buffer where it waits for processing. The print buffer is shared
among the ports, so data can arrive for different jobs
continuously.
PostScript A page description language (PDL) developed by
Adobe Systems in 1987.
Print density The relative darkness of print on the page.
