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.

Hexadecimal: 03
Horizontal Position
Carriage Return CR
Causes the current line to be printed, and then sets the current print position to the left
margin. If "Auto LF: On" is selected in the "Setup: INTERFACE" menu, a line feed
will also be performed.
Control code: CR
Hexadecimal: 0D
Backspace BS
Causes the current line to be printed, and then moves the current print position one
space to the left. The actual distance moved depends on the current character
spacing. Backspacing can be done up to, but not beyond, the left margin.
