Email function info missing

In the samples projects there is a project called EmailSkypePhoneSMs.
I can’t seem to find any information on the email function.
Where is the information on the email function?
I am trying to Print a sent email with a different font and size font.
Can this be done with this function?

Have a look at the sample code. It’s useful for setting an email to send using your default mail app.

It won’t be of any help for printing an existing email.
