Glossary of Terms (continued)
Term Definition
Landscape
A document layout that is viewed with the document's long axis in
a horizontal orientation.
LCD (Liquid Crystal
Display)
A device that contains a liquid crystal between two pieces of
polarized film through which reflected or ambient light can pass.
When a current is applied, the liquid's polarity changes and blocks
the passage of the light resulting in an opaque area of the display.
The areas are arrayed to form characters.
LED (Light Emitting
Diode)
A semiconductor that emits light when a current is applied.
Media
A generic reference to anything onto which the Printer can
transfer an image including cards, Ribbon and film.
LoCo (Low
Coercivity)
The coercivity value of magnetic media between 250 - 600 Oe
(ISO 7811-2). Fargo's Low Coercivity encodes at 300 Oe.
LPT Port (Line
Printer Port)
The system abbreviation for a PC's parallel Printer port.
Magnetic encoding
The process of orienting successive magnetic bits to produce a
serial data string.
Magnetic stripe
An area of the card with an applied or impregnated ferrous
material that may hold encoded data through a series of
prescribed polarity changes.
Magnetic Track
An area of a magnetic strip running the length of the card, with a
given width and position, constitutes a track. This is the area
dedicated to one data string, restricted to specific rules of format.
ISO Standards specify three magnetic tracks on the back of a
card. The JIS standard specifies one track on the front.
Magnetic Verify
A process to confirm proper magnetic encoding. After encoding,
the information is read off back and compared to the intended
string.
