When the printer is printing data from a host
and a second job is received by the printer
from a different host, Trickle Time prevents
the second host from timing out while it is
waiting for its data to be printed.
In order to support this feature, the port has
to be able to accept data from the host and
store it for future use.
For example, if the printer is printing a job
from the serial port and then receives a sec-
ond print job from the parallel port, the data
from the parallel port will "trickle" bit by bit
into the printer buffer to prevent a timeout
error from being sent back to the host con-
nected to the parallel port.
The selected value is the time that the
printer waits before getting the next
byte of data from the host. The Trickle Time
value should be less than the host time out
value, but not too much shorter or else the
printer fills up its buffer too fast. This func-
tion is not applicable for C/T hotport.
This is the value used by the printer to time
out from the current port and check the
other selected Port Types for data to print.
When the printer has not received data from
the host after a certain period of time, it
needs to time out in order to service the
other ports.
Data Terminal Ready. This configuration is
part of hardware flow control and deter-
mines when the Data Terminal Ready (DTR)
signal is generated. This signal indicates if
the printer is ready to receive data.
• False. Never asserts the DTR signal.
• True (factory default). Continuously
asserts the DTR signal.
• On-Line and BNF (buffer not full). Asserts
the DTR signal when the printer is online
and the internal serial buffer is not full.
• Off-Line or BF (buffer full). Asserts the
DTR signal when the printer is offline or
the internal serial buffer is full.
• On-Line. Asserts the DTR signal when the
printer is online.
This configuration is part of hardware flow
control and determines when the Request to
Send (RTS) signal is generated. This
signal indicates whether or not the printer is
ready to receive data.
• False. Never asserts the RTS signal.
• True. Continuously asserts the RTS signal.
• On-Line and BNF (factory default). Asserts
the RTS signal when the printer is online
and the internal serial buffer is not full.
• Off-Line or BF. Asserts the RTS signal
when the printer is offline or the internal
serial buffer is full.
• On-Line. Asserts the RTS signal when the
printer is online.
