This article explains how to set up a Brother QL-800 series printer for badge printing with the Diobox iOS app, including required paper tape, Bluetooth setup, and Wi-Fi setup.
Supported Printer Models
Diobox supports the following Brother QL-800 series printers for badge printing:
Brother QL-810W & QL-810Wc (Wi-Fi)
Brother QL-820NWB & QL-820NWBc (Bluetooth and Wi-Fi)
Compatible Paper Tape
The Brother QL-810 and QL-820 printers work with several label tapes. The following papers are compatible:
Before You Begin
Load the correct paper tape in the printer, for example DK-2251 or DK-2205, and close the cover.
Plug in the printer and power it on. Wait until the green status light is steady and the main screen appears.
Decide whether you will connect using Bluetooth or Wi-Fi based on your event setup.
Make sure you have the Diobox iOS app version 6.14 or higher installed.
Badge printing settings in Diobox are located at:

After the search completes, select your Brother QL-810W or QL-820NWB from the list.
Verifying Printer and Badge Setup
After connecting the printer:
In Badge Printing, verify that your Brother printer name is shown as the selected printer.
Select the badge template you plan to use.
Open any guest, tap Print Badge, and confirm the test badge prints correctly.
Check print quality, alignment, and that the content fits within the label.
If the output is misaligned or cut off, confirm that the badge template size matches the tape width and that the correct tape type is installed.
Troubleshooting Tips
Printer not listed in Diobox
Confirm the printer is turned on and Bluetooth or Wi-Fi is enabled.
For Wi-Fi, confirm both printer and device are on the same network.
Restart the printer and your iOS device if needed.
