Glossary of Terms (continued)
Term Definition
EPROM
(Electronically
Programmable Read
Only Memory)
A microchip based non-volatile memory storage device that
cannot be rewritten in the field. Firmware for many Fargo
Printers is stored on these chips and so a change of the chip is
necessary for an upgrade.
Escape sequence A string or control character that indicates to the processor that
what follows is a command and not data.
ESD (ElectroStatic
Discharge)
The discharge of static electricity (high voltage, low current) that
can damage electronic devices.
Ethernet A system of networking a series of computers for the sharing of
data or peripherals.
Film A thin flexible transparent sheet used to carry dye-impregnated
material or resin to be transferred to the card.
Firmware The instruction set, stored in chip memory, inside the Printer
that controls functional and operational data. Some models
require a chip change for updates; some Firmware can be
changed by reprogramming from the PC.
Flash Memory A microchip based non-volatile memory device that holds its
data when power is removed. This allows for field
reprogramming of the Printer commands, such as Printer
Firmware upgrades, without the necessity of changing chips.
Font A character set similar in style and form. Fonts can be graphical
or mathematical constructs, represented by a series of dots or
an Assembly of curves and lines.
FPGA (Field
Programmable Gate
Array)
A microchip with configurable logic circuits installed that takes
care of the very high speed and intensive data manipulations
needed by the printing engine.
