<!-- Please ensure you've completed the following steps by replacing [ ] with [x]-->

### Issue Details

* **Electron Version:**
  10.1.1
* **Operating System:**
  Ubuntu 20.04 + Linux 5.4.0-47-generic
* **Last Known Working Electron version:**
 7.1.2

### Expected Behavior
`webContents.getPrinters()` returns one printer. Besides, the OS provides additional virtual devices.
`webContents.print()` should open the print dialog and show those devices for selection.

### Actual Behavior
`webContents.print()` fails silently; in the print callback, `failureReason` is 'No valid printers available'

### To Reproduce
Just run `webContents.print()`
