Hi and welcome to the Forum.
Have you changed Display Scale settings for text at all? A couple of years ago a bug popped up when you moved the scale from 100% to anywhere between 100 and 200% that would cause issues such as being unable to print emails via Browser etcetera.
In Windows 10 Creator the scale is now just a drop down menu via Start > Settings > System > Display
Might be worth checking there.
The other thing to verify [ if you are accessing email via your browser ] is to make sure Windows is not selecting the wrong printer altogether ]. I use Microsoft Edge as my preferred browser, and when you click Edge's Settings > Print the pop up has a drop menu for printer options, including printers, and print to file options. I assume other browsers have a similar feature. Again, worth checking the issue is not there.
