Printronix L5035 Printer Configuration Data Bit, Paper Inst Instruction Line, Data Polarity

Chapter 3 Printer Configuration

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.
