Printing Using Multiple Interfaces In printers with multiple interfaces, you can use all interfaces without any limitations on which interface is to be used. You can use this function to temporarily connect a smart device to a nearby printer and print. The printer provides each interface with an independent receive buffer and switches the active interface depending on the priority, while handling data in each receive buffer. You can set one interface for the main connection. Data received from the main connection interface is handled with the highest priority.
By default, the interface that receives the first data transfer is set as the main connection interface; however, you can select the main connection interface in advance. In the status where all receive buffers are empty for more than the set time (1 second by default), interface switching is enabled. The interface that receives the data in this status becomes active. • You cannot use wired and wireless LANs at the same time. When a LAN cable is connected, wireless LAN is disabled. • When not using Bluetooth , set the Bluetooth security level to Middle or High in order to prevent third parties from unauthorized pairing.
You can change the security level with Epson TM Utility, TM-T88VI Utility, or the Interface Setup mode. You can select the main connection interface and set the time to enable interface switching from the software settings. For details on software settings, see "Software Settings" on page 59. 28
