End of Text ETX
If “ETX/ACK” is set to “On” in the interface setup menu, then receipt of an ETX causes the printer to
transmit an ACK to the host computer.
Since the ETX may be a legal value within an escape sequence, it is the user's responsibility to ensure that an
ETX used for data handshake is not sent within an escape sequence. The user must also ensure that the
maximum block size or the number of blocks sent at one time does not exceed the input buffer size of the
printer.
ETX/ACK handshake is available only with serial I/O.
