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.

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: 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.

Control code:

BS

Hexadecimal:
