Selects the bar code type and prints a bar code for the ASCII characters entered.
If the width of the bar code exceeds one line, the barcode is not printed.
There are two variations to this command. The first variation uses a NUL
character to terminate the string; the second uses a length byte at the beginning of
the string to compensate for the Code 128 bar code, which can accept a NUL
character as part of the data. With the second variation the length of byte is
specified at the beginning of the string.
Fixed-length codes can be aligned left, center, or right using the Align Positions
command (1B 61). Variable-length codes are always center aligned in A756
Emulation.
The check digit is calculated for UPC and JAN (EAN) codes if it is not sent from
the host computer. Six-character zero-suppressed UPC-E tags are generated from
full 11 or 12 characters sent from the host computer according to standard UPC-E
rules. Start/Stop characters are added for Code 39 if they are not included.
