Why change the IP address of the printer?
When you are connecting the printer to your POS or tablet to generate a receipt through LAN connectivity, both devices must be on the same IP network. If they are not aligned, the POS and printer cannot communicate, and receipts will fail to generate.
Generally, printers are shipped with a default IP address, so adjusting it to match your in-house network becomes necessary before using it.
Please note that while exact steps might differ slightly depending on the tool version you download, the overall method and flow remains the same. Before proceeding, ensure that,
You have a laptop or PC with good internet connectivity.
The Rongta RP410 printer is powered ON and connected to an active LAN.
The printer is connected via USB cable to your laptop or PC.
***In this guide, we’ll cover two ways to change the IP address of the Rongta label printer - using the Rongta Printer Tool and using the RTPrinter application.
Checking IP address of In-house network and printer:
In order to check the IP addresses of the In-house network and printer, follow the below steps:
To check your In-house IP address through POS or tablet, if it is connected through LAN,
Go to “Settings” → “Network and Internet Settings” → “Ethernet” and you will find the IP address listed there.
If the POS or tablet is connected via Wi-Fi,
Download and install the “Fing” application from Play store → Scan the network, and you will see the router and connected device IP addresses.
Now, to check the printer’s IP address,
Ensure it is connected to an active LAN, press and hold the “Feed” button, and then power ON the printer. Keep holding the feed button for around 5 seconds and release. A feed paper will print out, showing the printer’s current IP address.
If both the In-house network and printer IP address fall under the same range (for example, 192.168.0.0 and 192.168.0.78), no change is needed. However, if they fall under different ranges (such as 192.168.0.0 and 192.168.1.65), you will need to modify the printer’s IP address to match your In-house network.
Modifying the IP address of Rongta label printer (Using Rongta printer tool):
In order to modify the IP address of the label printer using Rongta printer tool, follow the below steps:
Once the IP addresses are checked, connect the printer via USB cable to your laptop or PC and open Google chrome. Search for “Rongta RP410 Tool,” open the “Tool Download” site. From the list of printer models, locate RP410 and download its tool.
After downloading, locate the files in your system, extract them, and proceed to run the tool. Once extracted successfully, open the tool folder and launch the "Printer Tool".
Inside the printer tool, first confirm that the connection between the laptop and printer is successful by clicking on “Connection Test.”
Next, click on the “Set Printer” button, select the “Ethernet” option, and you will find the editable IP address field.
Enter the new IP address according to the network information you checked earlier. After setting it, click on “Set.” The printer will emit a beep sound, and you should also see a confirmation message on the screen, indicating the IP has been changed.
To verify the modification, go to the “Test” section of the tool and select “Self Test.” A test receipt will print, displaying the new IP address.
This confirms that the IP address change was successful, and your printer is now ready to communicate with your POS or tablet.
Modifying the IP address of Rongta label printer (Using RTPrinter application):
In order to modify the IP address of the label printer using RTPrinter application, follow the below steps:
Start by connecting the printer via USB cable to your POS. Download and install the “RT-Printer” application from the Play Store. Once installed, open the application and you will immediately find a message saying “Rongta Printer Connected.”
Now ensure that the "Port Type" is set to USB and the "Printer Type" is set to 80mm in the application.
Just beside that, click on “Select USB Device” and choose a device option. Next click on “Connect” and observe the confirmation of a successful connection.
To verify the connection, perform a test print and check if the printer is connected to the POS correctly.
Now navigate to the "Settings" page of the application. Click on “PRINTER WIFI NET SET”, and a popup window will appear. Click on “Go To Set” within the popup window. You will find the option to modify the IP address.
Make the necessary changes to the IP address and save the IP modifications. To verify the modification, perform a test print again and a test receipt will print, displaying the new IP address.
This confirms that the IP address change was successful, and your printer is now ready to communicate with your POS or tablet.
