Data Bit 8
The Data Bit 8 parameter allows access to the extended ASCII character set.
Normally, this parameter is enabled. When this parameter is disabled, 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 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 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.
