(2) This command is one of the types of commands that is processed as it is received.
Processing takes place starting from the ones received first. Until the process of
the command previously sent is completed, the next command is not processed.
Therefore, if the printer is not in the idle state when this command is sent, the
program version data may not be returned immediately.
Notes (1) This command is effective only for the serial interface (RS-232C).
This command is not supported for a parallel interface (Centronics), since
