How to find IP address of Brother QL-720NW label printer?

The Brother QL-720NW gets its IP address from your router’s DHCP server. You need that address to configure badge printing in InstaCheckin — the iPad kiosk uses it to send print jobs directly to the printer over your local network.

Three ways to find it, ranked by convenience.

Method 1: Print a Network Configuration Label

The fastest method. No PC required, no router login needed — just the printer and a loaded label roll.

1. Make sure the printer is powered on and a label roll is loaded.
2. Press and hold the Cut button on top of the printer for about 3–4 seconds, until the printer starts printing.
3. The printer prints four labels. Discard the first three.
4. On the fourth label, look for the line labeled IP Address — for example: IP Address : 192.168.100.20

Write down that address. You’ll enter it in InstaCheckin in the final step.

If the label shows 0.0.0.0, the printer isn’t connected to your network. Skip to the troubleshooting section below.

Method 2: Use the Brother Printer Setting Tool

If the QL-720NW is connected to your Windows PC via USB — typical during initial setup — the Printer Setting Tool shows the network status without using a label.

1. Open the Printer Setting Tool on your PC. It’s installed automatically with the Brother driver package. If it’s missing, download it from Brother’s QL-720NW support page.
2. Click Communication Settings.
3. Navigate to the Wireless LAN tab, then click Current Status in the left-hand tree.
4. The current IP address appears in the status pane.

This method is also handy for confirming the IP after changing Wi-Fi credentials, without needing to physically reach the printer.

Method 3: Check Your Router’s Admin Panel

If the QL-720NW is powered on and connected to Wi-Fi, your router has a record of its IP address. This is the right option when you can’t reach the printer physically or don’t have a USB cable handy.

1. Open a browser on any device on the same network.
2. Go to your router’s admin panel — usually 192.168.1.1 or 192.168.0.1. Check the label on the underside of your router if neither works.
3. Log in with your router’s admin credentials.
4. Find the connected devices or DHCP client list section.
5. Look for a device named Brother QL-720NW or Brother. Its IP address is in that row.

One thing to keep in mind: DHCP-assigned addresses can change after a reboot. If the printer’s IP keeps shifting and breaking your InstaCheckin badge printing, set a static IP via the Printer Setting Tool or create a DHCP reservation in your router that maps the printer’s MAC address to a fixed IP. The MAC address is printed on the network configuration label from Method 1.

What To Do If the IP Address Shows 0.0.0.0

A 0.0.0.0 address means the QL-720NW hasn’t successfully joined your Wi-Fi network. Common causes:

• Incorrect SSID or password. Re-run the Printer Setting Tool, go to Communication Settings → Wireless LAN, correct the credentials, and click Apply. The printer restarts and attempts to reconnect.
• Wrong connection mode. InstaCheckin badge printing requires Infrastructure Mode — the printer connects through a Wi-Fi router. If the printer is set to Ad-Hoc mode, it won’t get a routable IP. Select Infrastructure Mode in the Wireless LAN settings and apply.
• IP conflict. Rarely, two devices land on the same DHCP address. Power-cycle the QL-720NW so it requests a fresh lease.

Once fixed, reprint the network configuration label (hold the Cut button 3–4 seconds) to confirm a valid IP address now appears on the fourth label.

If you haven’t connected the QL-720NW to Wi-Fi at all yet, follow the Brother QL-820NWB printer setup guide — the Printer Setting Tool Wi-Fi configuration steps are identical across both models.

Enter the IP Address in InstaCheckin

With the IP address in hand, log in to the InstaCheckin admin dashboard and go to Kiosk Settings → Visitor Badge. Check the Print Visitor Badge option, enter the IP address (for example, 192.168.100.20) in the Badge Printer IP Address field, and save.

The iPad kiosk sends a badge print job to the QL-720NW the moment a visitor completes check-in. For more on which Brother label printers work with InstaCheckin and how they compare, see the best label printers for visitor badges guide.
