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.
Full bleed Printing that covers the entire card surface.
Gamma The degree of contrast of an image or the display of a monitor
determined by the slope of a characteristic curve relating optical
density to relative log exposure.
Glossy / Matte A smooth polished surface in comparison to a rougher matte
surface. Fargo matte cards have a surface index (Ra) of
approximately 65 micro inches while glossy have a Ra = 3.
Glossy PVC A card made of PVC with a smooth polished surface (Surface
roughness of approximately 0 - 10 micro-inches). This is required
for direct to card Dye-Sublimation printing.
Graphical Device A Windows standard for protocol between drivers and
