Printing out EMAIL without addresses....

If you don't need to print like this too often, go to your Mail preferences>viewing tab and change the 'show header detail' to none, then print and change it back (if you prefer).

Or you can download something like 'Print Selection Service' which is linked below. It is a basic script that installs a print selection choice to your services menu (which is found by clicking the open application's main menu in upper left of screen) that you can use in just about any application to print only the highlighted area. Even going this way still takes a couple extra clicks though...
