CODABAR (NW-7)
One character is expressed with the NW-7 code by four thick and thin bars and 3 spaces, for a
total of seven lines. This code has been used for a long time, due to its relatively simple
configuration and the low printing precision requirements.
Usage
You can use numbers between 0 and 9, and six special codes (-, $, :, /, ., +). Four start/stop codes
(A - D) can be used, and configured as desired.
CODE 93
This bar code was developed to shorten the Code 39 bar code. It consists of four bars and spaces.
Usage
You can use all ASCII code characters (0 - 127) for data, and you can set a bar code of up to 255
digits. A check digit is assigned automatically.
CODE 128
This bar code was developed to shorten the Code 39 bar code and increase the reliability of data.
It consists of four bars and spaces.
Usage
You can use all ASCII code characters (0 - 127), and you can set a bar code of up to 255 digits. A
check digit is assigned automatically.
The code set selection character must be at the beginning of the data string. It is two characters (2
bytes). “{A” is used to select code A, “{B” is used to select code B, “{C” is used to select code C.
Accordingly, the shortest data string is two characters. Other special characters are also specified
by two characters starting with “{.” To specify a bracket ({), you use a double bracket ({{).
Bar Code Height
You can set the bar code height between 1 dot and 255 dots (35.9 mm or 1.4 in) with the
GS h
command. The initial value is 162 dots (22.8 mm or 0.9 in).
