Print email from Mail on iCloud.com
You can print messages if you want a paper copy for future reference.
In Mail on iCloud.com, select or open the message you want to print.
By default, a short header (the information at the top of the email) with the email’s sender, recipient, and date is displayed. To print the message with all of the message details in the header, click More (located to the right of the message’s From field).
Click the Action pop-up menu in the sidebar, then choose Print.
If you don’t see the sidebar, see Show or hide the sidebar in Mail on iCloud.com.
If you opened the message in a separate window, the Action pop-up menu is in the toolbar.
