75Host Interface SubmenuThe Host Interface Submenu enables you to select one of many types of interfaces between the printerand your host computer. The currently selected interface is indicated with an asterisk on the control panelmessage display. There are also submenus available to setup the hotport parameters for each interfacetype.Auto SwitchingAuto Switching gives the printer the ability to handle multiple data streams sequentially. With AutoSwitching, the printer can service hosts attached to the serial, parallel, and Ethernet ports as if they werethe only interface connected.For example, if the host computer sends one print job to the RS-232 serial port and a separate print job tothe IEEE 1284 parallel port, the printer's Auto Switching is able to handle both jobs, in the order they werereceived. The user does not have to reconfigure the selected interface between jobs.Port TypeSelect the parallel interface type connected to the printer. For example, if your printer is attached to onehost with a Centronics connection, you would select Centronics under the Parallel Hotport menu.Auto TrickleAuto Trickle is used to prevent a host computer from timing out because the parallel interface was busyfor too long. When Auto Trickle is enabled and the printer's buffers are almost full, the printer will begin totrickle data in (at the rate set in the Trickle Time menu) until the buffers start to empty.Auto Switching*Centronics 2SerialIEEE 1284 2USBEthernet 1Host Interface(from page 62)* = Factory Default1 If Ethernet is installed.2 If Parallel is installed.EthernetHotportUSBHotportSerialHotportParallelHotport 2Active HostPort TypeCentronics*IEEE 1284DisableAuto TrickleDisable*EnableTrickle Time1/4 sec*1/2 sec1 sec2 sec4 sec8 sec16 secOffTimeout30 sec*(10-60)Report StatusDisable*EnableTrickle Time1/4 sec*1/2 sec1 sec2 sec4 sec8 sec16 secOffTimeout30 sec*(10-60)Report StatusDisable*EnableTimeout30 sec.*(10-60)Timeout30 sec*(10-60)Switch Out OnData Timeout*Session Close
