This is issue is likely to be fixed in a future Microsoft update, however there is not a timeline at the moment for when this will occur. Preferred options for printing to avoid rolling back to a less secure platform:
- Use an SMPH IT managed lab computer
- Connect printer directly to the computer via USB cable.
