When CODE128 (m = 73) is used:
When using CODE128 in this printer, take the following points into account for data
transmission:
① The top of the bar code data string must be the code set selection character
(CODE A, CODE B, or CODE C), which selects the first code set.
② Special characters are defined by combining two characters "{" and one character.
The ASCII character "{" is defined by transmitting "{" twice consecutively.
