Binary information sent to the printer; a character set
grouping containing letters, digits, and punctuation
marks to be printed.
A value, parameter, attribute, or option that is
assigned by a program or system when another has
not been specified by the user.
Pertaining to the detection and isolation of a printer
malfunction or mistake.
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.
Media supplied in a fanfold stack instead of a roll
format.
Printer configurations, programs, downloaded files,
and fonts are stored in Flash Memory. Data in Flash
are not lost when power is turned off (Resident fonts
are fonts permanently stored in Flash and availalbe
at any time, via software commands.)
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.
