Appendix F
Default A value, parameter, attribute, or option that is 
assigned by a program or system when another has 
not been specified by the user.
Diagnostic Pertaining to the detection and isolation of a printer 
malfunction or mistake.
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.
Expanded Memory Cartridge (EMC) 
The expanded memory cartridge (EMC) is an extra 
32MB Flash memory storage cartridge that allows 
users to download forms, logos, and fonts.
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.
PGL Intelligent Graphics Printing software for the 
Printronix Graphics Language, designated for 
Printronix printers. PGL provides online forms, 
barcodes, and many alphanumeric text-generation 
capabilities and is compatible with earlier versions of 
Printronix IGP protocol and programming.
