Simple Setup for Wireless LAN
This printer comes with a mode (SimpleAP) that allows printers to connect with a smart device or a computer
without requiring a wireless access point. This allows you to easily setup a wireless LAN for the printer by using
a printer settings tool (Epson TM Utility for iOS/Android or EpsonNet Config) even without a network
environment such as access points.
SimpleAP mode is enabled by default when shipping from the factory. When SimpleAP mode is enabled and
the printer is turned on, the following information is printed automatically.

Although operations are performed in SimpleAP mode during the initial startup, operations switch to standard
mode (infrastructure mode) when changing settings in Epson TM-T88VI Utility for Windows or EpsonNet
Config. After switching, operations continue in standard mode. If you want to make settings in SimpleAP mode
again, initialize the communication settings. (see "Resetting the Interface Settings" on page 77

Chapter 1 Product Overview
Useful Functions for Smart Devices
You can easily connect this product to the network by using the NFC tag built-in to the printer or the QR code
printed on the status sheet.
NFC Tag
Bring a smart device that supports NFC close to the NFC tag to acquire the printer information (information
for specifying the device).
Specify the target printer using the acquired information to connect to the network.
QR Code
Capture the QR code printed on the status sheet with the camera on your smart device to acquire the printer
information (information for specifying the device).
Specify the target printer using the acquired information to connect to the network.
1
• Programming using Epson ePOS SDK is required to use these functions. These functions are
created by combining NFC touch and QR code capturing operations and the target printer
specifications using Printer Easy Select API.
See the "Epson ePOS SDK for Android/iOS User's Manual" and the Epson ePOS SDK sample
program for more details. The sample program also contains a sample implementation method for
reading an NFC tag and capturing a QR code.
• You can try a demo of these functions by using Epson TM Utility for iOS/Android.
27
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 56.
