Kiosk Receipt Printing Setup
This guide explains printer configuration for your MyOrderBox Kiosk, including built-in and external printer options, and what appears on customer receipts.
Printer Hardware Options
Sunmi K2 — Integrated Printer
The K2 terminal includes an integrated thermal receipt printer as standard.
Printer specifications:
- 80mm thermal receipt paper
- Prints at approximately 150mm per second
- Automatically connected at startup
- No additional setup required
The K2 printer works automatically once your kiosk is set up. Receipts will print after customers complete their order.
Sunmi Flex 3 — External Printer Required
Important: The Flex 3 does NOT have an integrated printer.
If you want to print receipts on a Flex 3 terminal, you must connect an external thermal printer.
Supported external printers:
- Sunmi T2 (recommended)
- Sunmi T4
- Other 80mm thermal printers with USB or Ethernet connectivity
Setting Up an External Printer

USB Connection (Recommended):
- Connect the printer's USB cable to the Flex 3 USB port

Ethernet Connection (For Network Printers):
- Connect the printer to the same network as your Flex 3
- Configure the printer's IP address in the Flex 3 settings
- Note the printer's IP address (usually shown on a boot screen or configuration page)

Troubleshooting Printer Issues
Printer Not Detected
Symptom: Settings show "No printer connected" or "Printer offline"
For external USB printers:
- Verify the USB cable is fully inserted into the Flex 3 USB port
- Power cycle the printer (turn off, wait 10 seconds, turn back on)
- Restart the kiosk
- Check if the printer appears in Settings > Hardware > Printers
For network printers:
- Verify the printer is connected to the same WiFi network as the Flex 3
- Check the printer's IP address matches what's configured on the Flex 3
- Restart both the printer and the Flex 3
Receipts Not Printing
Symptom: Orders complete but no receipt prints
- Check Settings > Printing and verify "Enable Receipt Printing" is On
- Verify a printer is selected as the default in Settings > Hardware > Printers
- Print a test receipt (see Software Configuration section above)
- Check that receipt paper is loaded in the printer
- Restart the kiosk
Poor Print Quality
Symptoms: Receipt text is faint, uneven, or hard to read
-
The printer head may need cleaning:
- Turn off the printer
- Gently wipe the thermal head with a soft, lint-free cloth
- Let it dry for 30 seconds
- Turn back on
-
The printer may be low on heat settings:
- Go to Settings > Hardware > Printers
- Look for Darkness or Intensity settings
- Increase the value slightly (usually range is 1-10, try 6-8)
-
Use genuine thermal receipt paper (not regular paper)
Printer Out of Paper
Symptom: Printer shows "Paper out" or "Cover open"
- Open the printer cover (usually a slide or hinged door)
- Load a new roll of 80mm thermal paper
- Ensure the paper feeds correctly into the slot
- Close the cover firmly until you hear it click
- Try printing again
Keep spare rolls of receipt paper on hand at all times.
Printer Maintenance
Daily
- Check that paper is loaded and the printer cover is closed
- Clear any paper dust from around the paper feed area
Weekly
- Verify test receipts print clearly
- Clean the thermal head with a soft cloth if print quality decreases
Monthly
- Review receipt logs in Back Office for any print failures
- Check for any physical damage to the printer
No Printer Option
If you don't want to print receipts, you can disable printing:
- Go to Settings > Printing
- Toggle "Enable Receipt Printing" to Off
- Customers will still see their order confirmation on the screen
- No receipts will be generated
You can re-enable printing at any time without affecting orders.
Best Practices
- Load paper regularly: Check printer paper at the start of each shift
- Test often: Print a test receipt weekly to catch issues early
- Keep spare rolls: Always have at least 2 backup rolls of receipt paper
- Monitor costs: Thermal receipt paper is inexpensive; budget for regular rolls
- Clean regularly: A clean printer head produces better receipts
