            Network Tethering Using Epson Printers

            Use network tethering to connect your register to a network via an Epson printer if Wi-Fi is unstable or there are limited ethernet ports. Connect the register to the printer using a USB cable for a stable and reliable Point of Sale (POS) system, while also charging the iOS device.

            Epson Printers and Network Tethering

            Epson printers provide another alternative for Ethernet connection. The network tethering offers a network connection to the register that is connected to the printer using a Lightning (or USB-C) to USB-A cable. This enables a stable and reliable operation of the POS system. In addition, the iOS device can be charged at the same time.

            Using Network Tethering

            • If the stores have unstable Wi-Fi and seek a stable ethernet connection.
            • If the stores have a shortage of ethernet ports and want to use a common ethernet port for both printer and register.

            Epson Printer Models supported are TM-m30II, TM-m30II-H or TM-m30II-NT

            The speed of the wired network communication using network tethering is about five Mbps or lower. Depending on the environment, the speed is slower than Wi-Fi communication.

            Prerequisites

            • Epson Printer firmware: 3.03A ESC/POS or later, or 3.03B ESC/POS or later
            • Install Epson TM Utility app from the App Store

            Check and Enable Network Tethering

            • Open the Epson TM Utility app on your register and check if your printer is selected at the top. If not, select through to find your printer and select it.
            • After selection, select "Change Printer Settings" > "Interface".
            • Find "Network Tethering" and check if you see Enabled or Disabled.
            • If turned off, select Network Tethering and an option to select Enabled or Disabled appears.
            • Select "Set to printer" button at the bottom right.

            Printer to iOS Device Connection

            • Connect the printer to a wired network.
            • Turn on the printer, and then wait until the Ethernet LED stops flashing and stays on.
            • On the iOS device, tap Settings > Wi-Fi > Disable Wi-Fi.
            • Connect the iOS device to the printer using a Lightning (or USB-C) to USB-A cable. Make sure to connect the cable to the USB-A Device Charging connector that is marked iPad.
            • On the iOS device, tap Settings > Ethernet, and then check that an IP address has been set.
            • If a DHCP server isn't used on the network, set the IP address and subnet mask manually.

            Troubleshooting

            If the Orange Warning LED stays on the printer after connecting to the iPad, follow these instructions:

            • Check the TM Utility app to make sure the printer is on the latest firmware.
            • If the firmware is the latest, power cycle the printer by powering it off and powering it back on again.
