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.
Control code: ETX
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” is set to “On” in the interface setup 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.
