I was printing emails ok from the windows 10 mail app on Sunday but when I tried today, the print panel was different ( black and different layout, rather than normel screen) and emails would not print. On clicking print box there was no indication of anything happening and no message. I am able to print from documents on my pc and see the print panel I expect. If I go into, say gmail via the web I can print ok and again see the print panel I expect? Any ideas please?
