Data Term Ready
Values: Online & BNF, True (default), False, Offline, BF, or Online.
This parameter must be set to match your host computer.
The DTR Function parameter is part of hardware flow control. This
parameter determines when the printer generates the Data
Terminal Ready (DTR) signal to the host computer. DTR 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 DTR signal.
• The False setting causes the printer to never assert the DTR
signal.
• The Online & BNF (Buffer Not Full) setting causes the printer to
assert the DTR signal only when the printer is online and its
internal serial buffer is not full.
• The Offline or BF (Buffer Full) asserts the DTR signal when the
printer is off-line or the internal serial buffer is full.
• The Online setting causes the printer to assert the DTR signal
whenever the printer is online.
Request To Send Function
Values: Online & BNF (default), True, False, Offline or BF, Online.
This parameter must be set to match your host computer.
The Request To Send 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.
