Data Bit 8

Enable (default). Allows access to the extended ASCII character set.

Disable. The printer interprets bit 8 of each incoming data character as a zero, regardless of its actual setting.

PI Ignored

The PI (Paper Instruction) signal is used to control vertical paper motion.

Enable (default). Causes the printer to interpret the eight data lines as DVFU commands when the PI signal is true.

Disable. Ignores the PI signal and treats the data as characters or control codes.

Data Polarity

The Data Polarity parameter must be set to match the data polarity of your host computer.

Standard (default). Does not expect the host computer to invert the data.

Inverted. Expects the data received on the data lines from the host computer to be inverted. Ones become zeros, and zeros become ones.

Resp. Polarity

The Response Polarity parameter must be set to match the response polarity of your host computer.

Standard (default). Does not invert the response signal.

Inverted. Inverts the response signal sent to the host computer.
