HP 5961-0509 manual Example Printing Text with the LB Command, 23-60The Character Group

zLabel Terminator— Terminates the LB command. You must use the special label terminator (refer to the DT command) to tell the printer to exit the label mode. If you do not use the label terminator, everything following the LB mnemonic is printed in the label, including other commands. The default label terminator is the non-printing end-of-text character ETX (decimal code 3). You can define a different terminator using the DT command.
