If there is anĮmail with a picture embedded in the message, the email prints with the picture unmodified and cuts off anything over the margin. If there is just a text email, the emails resizes correctly and prints correctly. I have set a customised paper size with no margins and the left margin reduces to about 16mm. Printing an email from outlook is printing with a 20mm left margin.
Attempting to print an email with everything in the printable margin is not possible as far as I can see. I have tried several options and if there is an email sent with a large picture or a table with set margins.
