Code 39 Bar Code
Description The Code 39 bar code is the standard for many industries, including the U.S.
Department of Defense. It is one of three symbologies identified in the American National
Standards Institute (ANSI) standard MH10.8M-1983. Code 39 is also known as USD-3 Code
and 3 of 9 Code.
Each character in a Code 39 bar code is composed of nine elements: five bars, four spaces, and
an inter-character gap. Three of the nine elements are wide; the six remaining elements are
narrow.
•
^B3 supports print ratios of 2.0:1 to 3.0:1.
• Field data (
^FD) is limited to the width (or length, if rotated) of the label.
• Code 39 automatically generates the start and stop character (*).
• Asterisk (*) for start and stop character prints in the interpretation line, if the interpretation
line is turned on.
• Code 39 is capable of encoding the full 128-character ASCII set.
