It sounds frustrating to deal with this issue, but let's try some additional steps to resolve it:
1. Ensure Devices Are on the Same Network
- Confirm that your iPhone, iPad, and Epson WF-2850 are all connected to the same Wi-Fi network. AirPrint won't work if they're on different networks.
2. Check Printer's AirPrint Settings
- Access the printer's settings menu and ensure AirPrint is enabled. From your Epson printer, you may need to navigate to **Settings > Printer Setup > Paper Source Settings** and set "Paper Setup Auto Display" to **ON**.
3. Update Printer Firmware
- Visit the Epson support website and check for any firmware updates for your WF-2850. Updating the firmware can resolve compatibility issues.
4. Use Epson's Smart Panel App
- Download the **Epson Smart Panel** app from the App Store. This app can help you manage and print from your Epson printer without relying on AirPrint.
If these steps don't resolve the issue, it might be worth contacting Epson support for further assistance.
