Centronics Parameters

Data Polarity

The Data Polarity 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 the host

computer.

Busy On Strobe

• Enable. Asserts a busy signal after each character is received.

• Disable. Asserts a busy signal only when the print buffers are

full.

Latch Data On

Specifies whether the data is read on the leading (default) or trailing

edge of the data strobe signal.

Prime Signal

• Enable. The parallel port will do a warm start (reboot) when the

host asserts the Prime Signal.

• Disable. The parallel port will not do a warm start when the

host asserts the Prime Signal.
