Section 8: Barcodes
150
An example of Code 39, with m = 0 and m = 1, follows:
m = 0 (the human readable character is printed)
m = 1 (the human readable character is not
printed)
s is the space width adjustment factor.
This parameter affects only space modules. It can be used to adjust the width of
space modules.
The range for possible s values is: -3 <= s <= 3.
Notes:
• The s value affects the actual width of the entire barcode.
To minimize the width of space modules, set s = xFD.
To maximize the width of space modules, set s = x03.
• If an invalid s value is specified, it is ignored and the default value (s
= 00) is used.
