My default printer changes every time I use a different printer. (Windows 10)
This is a new Windows 10 feature that sets the default printer to the last printer you used. If you don't want Windows to change the default, here is the resolution:
- Open the Settings app.
- Go to the following page: Settings -> Devices -> Printers and Scanners.
- See the option named "Let Windows manage my default printer".
- Turn it off
