Host Interface Submenu105Auto TrickleAuto Trickle is used to prevent a host computer from timing out because theparallel interface was busy for too long. When Auto Trickle is enabled and theprinter's buffers are almost full, the printer will begin to trickle data in (at therate set in the Trickle Time menu) until the buffers start to empty.Trickle TimeWhen the printer is printing data from a host and a second job is received bythe printer from a different host, Trickle Time prevents the second host fromtiming out while it is waiting for its data to be printed. 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 thenreceives a second print job from the parallel port, the data from the parallelport will “trickle” bit by bit into the printer buffer to prevent a timeout error frombeing sent back to the host connected to the parallel port.The selected value is the time that the printer waits before getting the nextbyte of data from the host. The Trickle Time value should be less than thehost time out value, but not too much shorter or else the printer fills up itsbuffer too fast.TimeoutThis is the value used by the printer to time out from the current port andcheck the other selected port types for data to print. When the printer has notreceived data from the host after a certain period of time, it needs to timeout inorder to service the other ports.Report Status• Disable (default). When a fault occurs on the printer, only the active portreports the fault to the host.• Enable. The port will report any fault even when it is not the current activeport.Switch Out On• Data Timeout (default). Allows Autoswitching when no data has beenreceived for the selected Time Out period.• Session Close. Allows Autoswitching only when the Network Socket isclosed. If the Ethernet option is not installed the Network Socket is alwaysreported as closed and this menu option is ignored.
