76Trickle TimeWhen the printer is printing data from a host and a second job is received by the printer from a differenthost, Trickle Time prevents the second host from timing out while it is waiting for its data to be printed. Tosupport 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 fromthe parallel port, the data from the parallel port will “trickle” bit by bit into the printer buffer to prevent atimeout 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. TheTrickle Time value should be less than the host time out value, but not too much shorter or else theprinter fills up its buffer too fast.TimeoutThis is the value used by the printer to time out from the current port and check the other selected porttypes 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 (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• Data Timeout (default). Allows Autoswitching when no data has been received for the selected TimeOut period.• Session Close. Allows Autoswitching only when the Network Socket is closed. If the Ethernet optionis not installed the Network Socket is always reported as closed and this menu option is ignored.USB I/O SubmenuBuffer Size in KThis option configures the amount of memory allocated for the USB buffer. You may specifybetween 1 and 16 Kbytes, in 1-Kbyte increments.The default is 16K.16 K*1K-16KUSB I/O(from page 62) * = Factory DefaultBuffer Sizein K
