End of Text ETX
If "ETX/ACK: On" is specified in the "Setup: INTERFACE" 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. It is not available when using
the parallel interface or the coaxial/twinaxial interface.
If the printing of low symbols is enabled, ETX will be treated as a printable character
instead of an I/O handshake control code.
Control code: ETX
