CODE128 This bar code consists of 103 bar code characters and three code sets, enabling 128
ASCII code characters to be printed. It has a variable length of columns.
• Code set A ASCII characters 00H - 5FH can be represented.
• Code set B ASCII characters 20H - 7FH can be represented.
• Code set C Two-digit numbers 00 - 99 can each be represented by one character. In
addition to the above characters, special characters are available:
• Shift character (SHIFT)
When used in code set A, one character next to a Shift character is treated as a
character of code set B.
When used in code set B, one character next to a Shift character is treated as a
character of code set A.
The Shift character cannot be used in code set C.
• Code set select characters (CODE A, CODE B, CODE C):
The code set following a code set select character is switched to code set A, B, or C.
• Function characters (FNC1, FNC2, FNC3, FNC4):
How the function characters are used depends on each application. In code set C, only
FNC1 is available.
• When sending print data, note these points:
(1) Each string of bar code data must begin with a code set select character (CODE
A, CODE B, or CODE C), which selects the first code set to use.
(2) Every special character is specified by a combination of two characters: a brace
“{” followed by one character. A brace “{” itself is sent twice consecutively.
