Print Bar Code

Selects the bar code type and prints a bar code for the ASCII characters entered. The

command is only valid at the beginning of a line. If the width of the bar code exceeds one

line, the excess data is not printed. Illegal data cancels the command.

There are two variations to this command: the first uses a NULL 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 NULL character as part of the data.

Note: Fixed-length codes can be aligned left, center, or right using the Align Positions

(1B 61) command. Variable-length codes are always center aligned.

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.

First Variation: String terminated with NULL Character
