Easily print an email without message header and username, but including background image in Outlook

As you know, when printing an email in Outlook, it will print out both of email header and email body as what you view in the Message window or Reading Pane. What's more, it usually adds your username above the message header. Here, I want to introduce the excellent Advanced Print feature of Kutools for Outlook, which enables you to print an email' message body only without the message header and username, and remaining the background image in Outlook.
