Chapter 3 Printer Configuration

RTS Function

Values: On/Offline&Buf (default), True, False or On/Offline. This parameter must be set to match your host computer.

The RTS Function parameter is part of hardware flow control. This parameter determines when the printer generates the Request to Send (RTS) signal to the host computer. RTS is a status signal that the printer sends to the host to indicate whether or not the printer is ready to receive data.

•The True parameter setting causes the printer to continuously assert the RTS signal.

•The False setting causes the printer to never assert the RTS signal.

•The On/Offline&Buf setting (the default setting) causes the printer to assert the RTS signal only when the printer is online and its internal serial buffer is not full.

•The On/Offline setting causes the printer to assert the RTS signal whenever either the printer is offline or its internal serial buffer is full.

DTR Polarity

Values: Normal (default) or Inverted.

This parameter must be set to match the DTR signal polarity of your host computer.

This parameter enables the DTR signal to invert if required for a particular installation.

RTS Polarity

Values: Normal (default) or Inverted.

This parameter must be set to match the RTS signal polarity of your host computer.

This parameter enables the RTS signal to invert if required for a particular installation.
