Chapter 3 Printer Configuration
82
Data Bit 8
Values: Enable (default) or Disable.
Normally, this parameter is enabled. It allows access to the
extended ASCII character set.
Paper Inst (Instruction) Line
Values: Enable or Disable (default).
The Paper Instruction line (PI line) controls paper motion. It is
dependent on your host computer.
Data Polarity
Values: Standard (default) or Inverted.
This parameter must be set to match the Data Polarity of your host
computer.
There are normally seven or eight data bits that define each ASCII
character sent from the host computer to the printer. The bits are
usually high-true.
Strobe Polarity
Values: Standard (default) or Inverted.
This parameter must be set to match the Data Strobe Polarity of
your host computer.
When the host computer sends a data strobe signal, it is indicating
that it has placed data on the data bus and that the data is valid
(i.e., enough time has elapsed for the data lines to stabilize). The
data strobe signal forces the printer to read the data lines into its
input buffer.
