Auto Trickle
This feature is used to prevent a host computer from “timing out” because the
parallel interface is “busy” for too long.

Enable. When the printer’s buffers are almost full, the printer begins to
trickle data in from the host (at the rate set in the Trickle Time menu) until
the buffers start to empty out.

Trickle Time
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.

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 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.

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 function is not applicable for C/T hotport.

buffer too fast. This function is not applicable for C/T hotport.
The options are 1/4, 1/2, 1, 2, 4, 8, and 16 seconds and Off.
The factory default is 1/4 second.
Timeout
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.

The range is 1-60 seconds, and the factory default is 10 seconds.
Report Status
•
Disable. When a fault occurs on the printer, only the active port reports
the fault to the host.
