When the printer is printing
data from a host and a second
print 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.

E.g., if the printer is printing a job from the
serial port, and then receives a second 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 connected 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 a fault occurs on the printer, only the
active port reports the fault to the host.
When enabled, this option sets the port to
report any fault even when it is not the cur-
rent active port.
Disable (factory default): The parallel port
will not perform a warm start (reboot) if the
host asserts the Prime Signal. Enable: The
parallel port will perform a warm start
(reboot) if the host asserts the Prime Signal.
The Data Polarity parameter must be set to
match the data polarity of your host com-
puter. Standard (factory default): Does not
expect the host computer to invert the data.
Inverted: Expects the data received on the
data lines from the host computer to be
inverted. Ones become zeros and vice
versa.
The Response Polarity parameter must be
set to match the response polarity of your
host computer. The Standard (factory
default) option does not invert the response
signal. The Inverted option inverts the
response signal sent to the host computer.
Enable (factory default): asserts a busy sig-
nal after each character is received. Dis-
able: asserts a busy signal only when the
print buffers are full.
Specifies whether the data is read on the
leading or trailing edge of the data strobe
signal.
When set to disable, the printer does not
process parallel/network data while offline.
Or else the printer continues to process (but
not print) the current network/parallel job
while the printer is offline until the printer's
buffer is full.
