Connecting a printer to the POS terminal

FireMenu Print Server printing in FireMenu is supported for Sunmi printers only. This guide explains how to connect a network Sunmi printer to the POS terminal and configure printing so tickets and kitchen slips are reliable on your LAN.

Step 1. Connect the printer to the network

1. Connect the printer to the router with an Ethernet cable.
2. Turn the printer on. Wait until the blue indicator shows that the printer is on the network.

Step 2. Print the printer status

1. Find the button on the back of the printer next to the ports.
2. Press the button twice to print a slip with printer status information.
3. On the slip, find the printer IP address (for example, 192.168.1.100).

Step 3. Chrome settings on Sunmi D3 Pro

1. Open Chrome.
2. In the address bar, enter: chrome://flags
3. In the search box, find “Insecure origins treated as secure”.
4. In the flag’s text field, enter the printer IP as http:// plus the address (for example, http://192.168.10.100). If other URLs are already listed, add the new one separated by a comma, for example: http://192.168.1.100,http://192.168.1.200
5. Set the flag to Enabled.
6. Click Relaunch at the bottom right of the browser.
7. After restart, close Chrome.

Step 4. Printing settings in FireMenu

1. Open FireMenu.
2. Go to Settings → Print tab.
3. Under Print driver, select FireMenu Print Server (alongside Standard print).
4. Click Add printer and fill in:
   • Name — a label for the printer (for example, “POS”).
   • Type — Ethernet.
   • IP address — the address from the status slip (for example, 192.168.1.100).
5. Choose what to print on this printer:
   • POS terminal — terminal receipts.
   • Cash drawer — if a drawer is wired to the printer and you need open pulses.
   • Switches with your kitchen names (they may appear as “Kitchen”, “Bar”, etc.) — for kitchen tickets per area.
6. Click Save changes at the top of the form, then Save settings as default so the venue settings are stored in the cloud.

After saving, run a test print from the POS; if everything is correct, the slip should appear on the printer.

Common issues

• Still no printing after first-time setup — follow Sunmi printer troubleshooting (network, Chrome, Print tab, static IP).
• Chrome cannot print to the printer IP — check Insecure origins treated as secure and that the value uses http:// with the correct IP.
• Printer not on the network — confirm the cable is in an active router port and the network LED is OK; the IP on a new status slip may change after DHCP renewal.
• Missing print target in FireMenu — kitchen names come from venue configuration; if a switch is missing, ask your administrator.
