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.
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.
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.
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.)
Media supplied in a fanfold stack instead of a roll
format.
Nonvolatile memory. See Nonvolatile Memory.
A collection of printing characteristics for printing
alphanumeric characters, all of which combine to
produce a distinctive style of print.
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.
The hardware component used to link two devices by
common physical interconnection, signal, and
functional characteristics.
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.
The material labels are attached to during their
manufacturing process. Attachment is usually
accomplished with an adhesive.
