Bar code E: Code 128

This bar code consists of the full ASCII set of 128 characters and

number of digits is variable in length. Checksum is performed through

the modulus 103 calculation and added to the end of digit. This printer

supports code subsets A, B and C. When one character of either A, B,

or C is added to the top of the transmission code, the printer selects

the starting order of the code subset. When neither A, B, nor C is

added to the top of the transmission code, code subset B is selected.

Code subset A is a bar code which consists of standard upper-case

alphabetic characters, numerics, keyboard characters, control

characters and special characters. To select code subset A, data must

be coded beforehand in ASCII code A (65 decimal, 41 hex).

Code subset B is a bar code which consists of standard upper- and

lower-case alphabetic characters, numerics, keyboard characters,

control characters and special characters. To select code subset B,

data must be coded beforehand in ASCII code B (66 decimal, 42 hex).

Code subset C is a bar code that consists of special characters and 2

digits from 00 to 99. The numeric digit number gets coded twice. To

select code subset C, data must be coded beforehand in ASCII code

C (67 decimal, 43 hex). When code subset C is selected, the

alphabetic characters should not be coded.

Special character processing

Characters of code number 96 or more are special characters.

To input these characters, the 2-character input reference table is

shown below.

Code 2 characters

96 &A FNC3 FNC3 - NA -

97 &B FNC2 FNC2 - NA -

98 &C SHIFT SHIFT - NA -

99 &D CODEC CODEC - NA -

As an example of special character processing, code subset

selection is provided:

First select: Either 1-character entry of A, B, or C

Switch in midway: 2-character entry such as &D, &F
