[Outline] This command defines up to a 50-byte message in one line. If the value of n is specified
beyond the range, the data following n will be treated as the print data.
Once the message is defined, it remains valid until it is redefined. The data should end with
CR (0DH) or LF (0AH). If the data exceeds 50 bytes, the subsequent data will be treated as
the print data.
Once the message is defined, it remains valid until it is redefined or the download deletion
command (ESC DC2 n1 n2) is executed.
