How To Setup a TSP100IIIW on a WiFi Network

You are here:


This application note explains how to manually setup the TSP100IIIW on a network with Windows, iOS and Android without the use of WPS.

Supported Printers: TSP100IIIW
Supported Interfaces: Wi-Fi
Supported Environments: iOS,  Android, Windows  (32/64-bit)


Before you begin

Important: Please take note of your wireless network SSID (Name) and password, as well as your printer’s MAC and IP Addresses. The printer’s MAC and IP Addresses are obtained by printing a self-test. 

How To: Print a Self-Test

The printer’s SSID is “TSP100III-XXXXXX”, where “XXXXX” are the last 6 digits of the printer’s Mac Address located on the self-test.

The Mac Address can be found under “Network Configuration” at the top of the sheet.

For the initial setup, the printer provides a temporary IP Address ( located on the self-test.

The IP Address can be found under “Current IP Parameters” at the bottom of the sheet.

Connect TSP100IIIW Manually

1. Open the Wi-Fi settings on a PC/tablet/phone and connect to the printer’s broadcasted network.


On a Windows device, Wi-Fi settings icon can be found in the bottom right corner of the taskbar. Connect to the boadcasted TSP100III-XXXXXX

NOTE: It will take some time (about 1 minute) until connection is confirmed. It is also normal for it to read “No Internet”.


On an iOS or Android device, Wi-Fi can be found in Settings > Wi-Fi

2. Open a browser (e.g., Google Chrome, Microsoft Edge or Safari) and type the printer’s IP Address ( into the address bar and the Web Configuration page will appear.

3. Click “Login”.

4. Log in with the following credentials and click “Sign in”.

Username: root
Password: public

NOTE: It is recommended to change these credentials for increased security. If you do, take note and safeguard the new credential for future web UI access. If the above credentials are not accepted, the network interface requires a reset. Use the following article to do so: How To:  Reset the Network Interface of an Ethernet or Wi-Fi Printer

5. Click “WLAN Settings”.

6. Enter the following case-sensitive information:

  • Select “Infrastructure
  • Enter the SSID (your WiFi’s  name)
  • Enter the Security Type (AUTO if available – WPA2/AES if not)
  • Enter the Security Key (your WiFi’s password)
  • Click “Submit”

NOTE: The printer cannot connect to a 5g network. Ensure that the network you are attempting to connect to is solely a 2.4g network. It may be necessary to split a combined 2.4g/5g network into 2 separate networks. Additionally, the Security Type is determined by your network. The printer can only connect to WPA2/AES.

NOTE: The Wi-Fi name must match exactly as it appears or it will fail. The below example will fail if your network is broadcasted as “Work_Network 2g” because it is missing the capitalization:

7. Confirm the information entered and click “Save”.

8. Select “Save -> Configuration Printing -> Restart device” and click “Execute”.

9. A new page will appear confirming the changes were successful, close the browser while the printer reboots. The printer’s ready LED will begin flashing blue and part of the network configuration page will print.

10. It can take several minutes for the printer to complete the setup. When completed the ready LED will turn solid blue and the rest of the network configuration page will print. At the bottom of the page the Current IP Parameters Status section provides a new IP Address.

NOTE: If the printer fails to connect to the network and all information is being entered correctly, and the AUTO selection for Security Type is not available, it’s possible the router’s security is not configured as compatible with the printer. In these cases, it’s recommended to reach out to the ISP to confirm the router’s current Security Type configuration matches the setting from Step 8 and is not set to a combo (WPA/WPA2 or TKIP/AES).


Congratulations! You have successfully connected the TSP100IIIW to a network using the manual method.
