Mail Messages printing out too small
On a MacBook Pro running Catalina, I have a problem printing mail messages: no matter how large the screen font is selected, If I print the message it always comes out with an unreadably small font. This mismatch only happens in the Mail app; printing from other apps gives me WYSIWYG when printed.
Do I have a corrupted Mail app?
