Emails cannot be printed only plus minus symbol on paper

When in print an email sometimes i only get a blank page with three symbols on it.
The mail is not getting printed.
Using the newest version 8.2.1473.

Does it look ok “in the preview window” before you print ?

Yes in the preview i can see the content completely.

That is strange as normally whatever is in the preview will print the same on paper.

Do you get the same result if you print to PDF?

That is not so simple to say because the issue is not at every printout.
It is only sporadically.
