Hi there! I understand you're trying to add a printer through the Liene Photo app on your Windows device, and the process takes you to the list of apps instead of letting you add the printer. Let's get this sorted out.

To start, can you tell me a bit more about your setup? For example:
- Are you trying to connect the printer via Wi-Fi or Bluetooth?
- Is the printer already powered on and in pairing or connection mode?
- Have you ensured the printer and your PC are on the same network, if using Wi-Fi?
- Did you try clicking any "Add Printer" or "Switch" buttons in the app, or did it jump straight to the app list?

Once I have these details, I can guide you through some steps. Meanwhile, here’s a general approach that often helps:

1. Power on the Printer: Hold the printer's power button for about one second to turn it on. Make sure it's ready to connect.
2. Network Connection: Check that your PC and printer are connected to the same Wi-Fi network (if applicable). Not being on the same network can cause the app to not detect the printer.
3. App "Add Printer" Feature: On the Liene Photo app home screen, look for and tap the "Add Printer" button. If you see a "Switch" button (usually top right), pressing that may help toggle printer modes or refresh the device list.
4. Avoid App List Redirect: If tapping "Add Printer" redirects you to a list of apps, it may be caused by your Windows system triggering an incorrect association or a permission issue. Try restarting the Liene Photo app and the computer, then attempt again. Alternatively, make sure the Liene Photo app has the required permissions to use your network and Bluetooth (if applicable).

If you’re attempting this over Bluetooth, also ensure Bluetooth is enabled on your PC and the printer is discoverable. You can verify Bluetooth devices through your Windows Settings > Devices > Bluetooth & other devices.

Could you confirm these points or describe precisely when and how it moves to the app list? This will help me tailor the next steps for you.
