GLOSSARY

portrait page orientation	Orientation of print lines or the top of an illustration
	parallel to the short edge of the paper.
PostScript	Page description language developed by Adobe
	Systems, Incorporated. PostScript 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.
ppm	Pages per minute.
printer	Component of the DocuPrint Printing System that
	accepts data from the controller and prints the document
	according to the print attributes specified by the user.
	The printer also provides paper stacking, collating, and
	optional finishing. “DocuPrint printer” or “printer” refers to
	the base printer engine (IOT) only, without the controller
	and interface.
printer controller	See controller.
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.
protocol	Formal set of conventions governing the format of data
	and the control of information exchange between two
	communication devices.
queue	List of documents waiting to be processed.
Random Access Memory (RAM)	Volatile memory used for temporary storage of data and
	software commands, used by programs for immediate
	task processing.
Read-Only Memory (ROM)	Solid-state memory for programs. It cannot be rewritten.
resolution	The number of dots per 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 is produced.
short-edge feed (SEF)	The movement of paper through the printer in the
	direction of the paper width (the shorter side of a sheet
	of paper).
simplex printing	Printing on one side of the page. See also duplex
	printing.
small computer system interface	An accepted standard for connecting devices to
(SCSI)	computers.
