Whenever I print an email in Outlook 2003, it prints at the top:
How do omit all that junk and just output the body of the message?
I believe print styles can be used to change how your emails are printed
If that doesn't work for you, follow the instructions here. It gives you a few methods for doing so. The "Remove headers from the message form" is probably the most integrated method, but will change how you see emails when you jsut view them.
Dan McG is right.
In Outlook 2003, select File > Page Setup > Define Print Styles. You can make a copy of the default "Memo Style" there (which is the default style used for emails) and edit your copy to remove whichever headers and footers you don't want to see.
