Additional information for Code 128:
Code 128 covers the range of ASCII codes from 0 to 127 with the help of 3 code sets A, B and C, which can be
used in one and the same barcode.
Code set A: consists of characters with ASCII codes from 0 to 95 and function characters FNC1, FNC2, FNC3,
FNC4, SHIFT, CODEB, CODEC.
Code set B: consists of characters with ASCII codes from 32 to 127 and function characters FNC1, FNC2,
FNC3, FNC4, SHIFT, CODEА, CODEC.
Code set C: is used for coding sections of the barcode which consist only of digits. Each character defines 2
digits, that are coded with ASCII code from 0 to 99. Also possible are function characters FNC1, CODEA,
CODEB.
The barcode always begins with one of the characters CODEA, CODEB or CODEC, which defines the code set
that will be used. If necessary the code set can be changed by inserting one of these characters in the barcode.
The character following SHIFT is treated as a character of code set B if the current code set is A, and as a
character of code set A if the current code set is B. If a character unacceptable for the current code set is given
then barcode is not printed.
Function characters are defined with 2 bytes as follows:
Coding Character
Decimal Hexadecimal Text
FNC1 123, 49 7B, 31 {1
FNC2 123, 50 7B, 32 {2
FNC3 123, 51 7B, 33 {3
FNC4 123, 52 7B, 34 {4
CODEA 123, 65 7B, 41 {A
CODEB 123, 66 7B, 42 {B
CODEC 123, 67 7B, 43 {C
SHIFT 123, 83 7B, 53 {S
{ 123, 123 7B, 7B {{
Code 128 Auto uses the same code sets, but the printer test the data and automatically switches between the
code sets, trying to print a minimum width barcode. D
i
contains only the real data to be printed.
EAN 128 uses Code 128 code sets, but puts an FNC1 code in the beginning, and if human readable text is
enabled, the text is separated in fields (Application identifiers). If any of the fields contains invalid data, the
barcode is not printed. Code sets are switched automatically like Code 128 Auto .
102. Settings for 2D barcode PDF417 ( GS p )
Code: [1Dh] + [70h] + e + c + r
e is error correction level for barcode PDF417. At value bigger than 8 the printer chooses automatically
the appropriate level depending on the quantity of the coded data, else the defined value is being
used.
c is the max number of columns, which the printer uses for printing the barcode.
r is max number of rows, which the printer uses for printing the barcode.
