Technical documentation for badge label printing

Eventee offers a flexible badge-label printing solution that streamlines attendee check-in across various environments.

To accommodate different hardware setups, the platform supports badge label generation through two primary methods: Web Check-in for browser-based printing on desktop platforms, and the Eventee Check-in mobile app for iOS and Android devices.

Browser-based printing via the web check-in app

Supported browsers

Please note that following browsers are not supported for this printing flow: non-Chromium browsers (e.g., Firefox, Safari).

Setting up platforms via USB

1. MacOS

No special software is required on macOS.

Set up instructions:

1. Connect the Brother printer via USB

2. Open the Eventee Check-in web app in a supported browser (Chrome/Edge/Opera)

3. Go to Printers in the Check-in app

4. Click Scan / Refresh printers

5. Select the Brother printer and try printing

2. Windows

On Windows, you need to install a WinUSB driver for the printer using Zadig.

Set up instructions:

1. Download Zadig (https://zadig.akeo.ie/)

2. Run Zadig as Administrator

3. Options → List All Devices

4. Select your Brother printer from the dropdown

• If multiple interfaces exist, choose one without an existing WinUSB driver

5. Select WinUSB (not libusbK) and click Replace Driver

6. Reconnect the printer (unplug/replug the USB cable)

7. In the Check-in app, refresh printers and try printing again

📌 Important note (Windows): After this setup, standard Windows printing might not work with this printer until you revert the driver.

3. Linux

Linux is not supported yet for web-based badge/label printing.

Mobile printing via the Eventee check-in app

Badge/label printing is also supported in the Eventee Check-in mobile app:

• iOS (iPhone / iPad): ✅ Supported

• Android (phone/tablet): ✅ Supported

Instructions for pairing the printer via Bluetooth:

1. Enable Bluetooth on the printer (pairing mode, if required)

2. On your mobile device, open System Settings → Bluetooth

3. Pair/connect the printer via Bluetooth

4. Open the Eventee Check-in app

5. Go to Settings → Printers (or Printing)

6. Tap on the green button “Ask permission and scan” and select the printer

Once the printer is connected in system settings, it should be discoverable inside the Eventee Check-in app.

How to fix Bluetooth pairing issues with your printer:

1. It is not possible to connect to the printer while another device is currently connected. To establish a new connection, you must first disconnect the printer from the active device.

2. If you have verified that no other devices are connected and the issue persists, please disable and re-enable Bluetooth in the printer's settings.
