Printer Control
Language (PCL) Printer description language defined by Hewlett–Packard
Company. PCL describes the input (type, format,
characteristics), performs the processing functions (logical
processing), and describes the output (type, format, font
selection, accounting options) of a print job.
Printer Controller Component of the DocuPrint NPS/IPS that manages the
spooling and processing of print jobs.
print quality
adjustment (PQA) The process by which the NPS/IPS maintains the electrostatic
state of the xerographic subsystem to ensure optimal print
quality.
print queue Temporarily stores print jobs that have been sent over the
network but that have not yet been forwarded to the printer.
process color
printing In process color printing, every color in the spectrum is printed
by combining various percentages of the four-color process
primary colors—cyan, magenta, yellow, and black.
queue List of documents waiting to be processed.
random access
memory (RAM) Storage that allows data (such as documents) to be stored and
retrieved directly by address location without reading through
any other data.
raster data Binary data, usually consisting of dots arranged in scan lines,
according to the print order.
rasterization The creation of a bitmap image of a page for printing.
resolution The number of picture elements (pixels or dots) per square area
unit. An imaging system converts a character from digitized data
into a printed image composed of these tiny dots. The greater
the number of dots per inch (i.e., higher the resolution), the
clearer the image produced.
RGB A printing industry standard color definition model in which all
colors are defined in terms of values for the three additive
primary colors: red, green, and blue. Refer to color definition
model.
scale To adjust font or image size according to given proportions.
shade Color resulting from adding black to a pure hue.
short-edge feed
(SEF) Laser printing in which the paper is fed through the imaging
system short-edge first. The movement of paper through the
printer in the direction of the paper width (the shorter side of a
sheet of paper).

long-edge feed.
simplex printing Printing on one side of the page. Contrast with duplex printing.
