PI Ignored
The PI (Paper Instruction) signal is used to control vertical paper motion.
v
Enable (the default). Ignores the PI signal and treats the data as characters or
control codes.
v
Disable . Causes the printer to interpret the eight data lines as VFU commands
when the PI signal is true.
Data Polarity
The DATA POLARITY parameter must be set to match the data polarity of your
host computer.
v Standard
(the default). Does not expect the host computer to invert the data.
v
Inverted . Expects the host computer to invert the data received on the data
lines. Ones become zeros, and vice–versa.
Data Request Polarity
The DATA REQUEST POLARITY parameter must be set to match the data request
polarity of your host computer.
v
Standard (the default). Does not invert the request signal.
v
Inverted . Inverts the request signal sent to the host computer.
Strobe Polarity
The STROBE POLARITY must be set to match the data strobe polarity of your host
computer. When the host computer sends a data strobe signal to the printer, this
enables the printer to read the data bus.
v
Standard (the default). Does not expect the data strobe signal to be inverted.
v
Inverted . Expects the host computer to invert the data strobe signal.
Buffer Size in Kbytes
This parameter determines the size of the input buffer, in 1K increments. Up to
16K are available.
