A–10 Bar Codes
Bar Code Styles
The following sections discuss the bar codes the printer can make. The
characteristics of bar code styles, P1 – P9 values, and their defaults are also
discussed.
Code 39
In the Code 39 style, there are five dark bars and four light bars for a total of
nine bars. Three bars are wide and the other six are narrow. Both light and
dark bars are coded to define the character. A narrow light/dark bar is
assigned a binary 0 and a wide light/dark bar is assigned a binary 1.
Code 39 has the following characteristics:
• Character set includes ten digits (0 – 9), uppercase letters A – Z, plus
eight additional characters (– . $ / + % SP *)
• START and STOP codes
• No CENTER code
• Definable intercharacter gap
• Variable length characters per complete symbol
• If a checksum is required for bar code readability, you must include it as
part of the data.
Extended Code 39
For printable characters, Extended Code 39 prints like Code 39. With control
characters, Extended Code 39 decodes and prints the control characters as
their combined printable codes. See Table A–1 for the Extended Code 39
ASCII character set.
