3–28 Configuring the Printer
PI Ignored
The PI (Paper Instruction) signal controls vertical paper motion. It is dependent
on your host computer.
Enable: Ignores the PI signal and treats the data as characters or control codes.
Disable: Causes the printer to interpret the eight data lines as VFU commands
when the PI signal is true.
Data Polarity
This parameter must be set to match the Data Polarity of your host computer.
Standard: 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 vice versa.
Resp. Polarity
The Response Polarity parameter must be set to match the Response Polarity of
your host computer.
Standard: Does not invert the response signal.
Inverted: Inverts the response signal sent to host computer.
Latch On Data
Specifies whether the data is read on the leading, middle (default), or trailing
edge of the data strobe signal.
Prime Signal
Enable: The parallel port will do a warm start (reboot) if the host asserts the
Prime Signal.
Disable: The parallel port will not do a warm start (reboot) if the host asserts the
Prime Signal.
