Hi there! I understand you're seeing all files as "ghosted" when you try to print them using the Epson iPrint app on your Mac. Just to clarify a bit—when you say "ghosted," do you mean the file icons or options are faded out or unavailable in the app, or is the actual print output looking faint, duplicated, or blurry (ghosting effect)?

This will help me guide you better. Meanwhile, I’ll walk you through some common checks:

1. Check Connection and App Permissions
- Make sure your Mac and your Epson printer are connected to the same Wi-Fi network.
- Ensure the Epson iPrint app has permission to access your files, especially if they are photos or PDFs in your system.

2. File Format and Source
- Are you trying to print files from a particular location or app on your Mac? Sometimes, if the iPrint app can’t access certain file types or locations, the files may appear unavailable or 'ghosted.'
- Try opening the files on your Mac outside the iPrint app to confirm they are not damaged.

3. App and OS Compatibility
- Your Mac is running OS X 10.15.7. The Epson iPrint app sometimes has compatibility nuances on older MacOS versions. Make sure you have the latest version of Epson iPrint installed from the Mac App Store.

4. Restart Devices
- Restart your Mac and the Epson printer. This can refresh connections and app states.

5. Reinstall Epson iPrint App
- If the files still appear ghosted, try uninstalling and reinstalling the Epson iPrint app to reset its app data and permissions.

If the issue persists, it might be related to a network or app glitch. Could you tell me if you recently updated your MacOS, the app, or your printer firmware? Also, were you able to print files fine before this issue started?

Let me know about these details, and I can guide you further!
