Code 39 Bar Code
Description: The Code 39 bar code is the standard for many industries, including the
U.S. Department of Defense (DOD). 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 (*)
Code 39 is capable of encoding the full 128-character ASCII set.
