Printronix T4204 manual Glossary

E Glossary

Direct Thermal Media	Media coated with special chemicals that act as an
	accelerator, acceptor dye and binder. In Direct
	Thermal mode the heat from the selected rectangular
	elements in the thermal printhead makes direct
	contact with the media (no ribbon is used) and
	causes a chemical reaction that creates the image on
	the media.
Direct Thermal Printing	A printing method in which no ribbon is used to
	transfer data from the printhead to the media to
	create an image. The thermal printhead selectively
	heats small rectangular elements which make direct
	contact with the coated media.
DRAM	Dynamic Random Access Memory. Can be read
	from or written to at any time. DRAM is volatile:
	Whatever is in DRAM is lost when power is turned
	off.
EPROM	Erasable Programmable Read Only Memory.
	Programs, instructions, and routines permanently
	stored in the printer that cannot be written to. Files in
	EPROM are not lost when power is turned off.
	(Resident fonts are fonts permanently stored in
	EPROM and available at any time, via software
	commands.)
Fanfold Media	Media supplied in a fanfold stack instead of a roll
	format.
Flash Memory	Nonvolatile memory. See Nonvolatile Memory.
Font	A collection of printing characteristics for printing
	alphanumeric characters, all of which combine to
	produce a distinctive style of print.
Host Computer	The computer that stores, processes, and sends
	data to be printed, which communicates directly with
	the printer. The term “host” is used to indicate the
	controlling computer, since modern printers are
	themselves microprocessor-controlled computer
	systems.
Interface	The hardware component used to link two devices by
	common physical interconnection, signal, and
	functional characteristics.
IPS	The speed at which the media is printed based on a
	rate of Inches-Per-Second. The T4204 can print at 2,
	3, 4, 5 and 6 IPS.
Label Liner (backing)	The material labels are attached to during their
	manufacturing process. Attachment is usually
	accomplished with an adhesive.
