Data Term Ready; Request To Send - Printronix P9212 Setup Manual

Data Term Ready

The Data Term Ready parameter selects how the printer controls the Data
Terminal Ready (DTR) signal. DTR is a control signal from the printer to the
host computer indicating whether or not the printer is ready to receive data.
You should set this parameter according to the manner in which the host
computer uses DTR.
•
On-Line and BNF: The printer asserts DTR whenever it is on-line and
its internal input buffer is not full (BNF).
•
Off-Line or BF: The printer asserts DTR whenever it is off-line or its
buffer is almost full (BF).
•
False: The printer continuously de-asserts DTR.
•
True: The printer continuously asserts DTR.

Request To Send

The Request to Send parameter selects how the printer controls the Request
to Send (RTS) signal. RTS is a control signal from the printer to the host
computer indicating whether or not the printer is ready to receive data. You
should set this parameter according to the manner in which the host computer
uses RTS.
•
On-Line and BNF: The printer asserts RTS whenever it is on-line and
its internal input buffer is not full (BNF).
•
Off-Line or BF: The printer asserts RTS whenever it is off-line or its
buffer is almost full (BF).
•
False: The printer continuously de-asserts RTS.
•
True: The printer continuously asserts RTS.
