(0 = End of command)
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 bar code 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.
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.
Rotated barcodes set with small modules (select bar code width command 1D 77 n , with n = 1 or 2) and PDF 417
barcodes in any orientation are printed at low speed, for better readability.
Exceptions
The command is only valid at the beginning of a line.
Illegal data cancels the command.
Values:
First variation: String terminated with NUL character. Length k is not specified in command string; it depends on the
bar code being printed.
