What does the single letter 'P' in email mean?

Question

I notice that many of my emails have this single letter 'P' beside a sentence and that sentence is usually about protecting nature.

Example:

P Print Only When Necessary

What does the P mean? Is it just a typo error?

Update

The P is not "Please", it is a icon

The icon can be find under the letter P in the following link: http://speakingpowerpoint.files.wordpress.com/2011/10/symbol-fonts-full-page2.jpg

It's not part of standard English. Perhaps it's just a smiley like this one asking about the letter 'J'. If you get 'many' such emails, why not ask one of the people who sends them? — FumbleFingers, Nov 02 '11 at 04:09

Like the link FumbleFingers posted, it's indeed a graphic, though not a smiley.

The capital P in the font Webdings appears to be a river through a field with a tree in the distance. However, if you don't have the font installed or the font has been stripped (due to plain text emails or what have you) you just see P
