Trickle Time
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 second print job from
the parallel or USB port, the data from the parallel or USB 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.
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 timeout in order to service the other ports.
Report Status
•
Disable (factory default). When a fault occurs on the printer, only the active port reports the fault to
the host.
•
Enable. The port will report any fault even when it is not the current active port.
Switch Out On
NOTE: This option is only available under Ethernet Hotport.
•
Data Timeout (factory default). Allows Autoswitching when no data has been received for the
selected Time Out period.
•
Session Close. Allows Autoswitching only when the Network Socket is closed. If the Ethernet option
is not installed the Network Socket is always reported as closed and this menu option is ignored.
