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 Code subset A Code subset B Code subset C
96 &A FNC3 FNC3 - NA -
97 &B FNC2 FNC2 - NA -
98 &C SHIFT SHIFT - NA -
99 &D CODEC CODEC - NA -
100 &E CODEB FNC4 CODEB
101 &F FNC4 CODEA CODEA
102 &G FNC1 FNC1 FNC1
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
