printer-friendly template questions

I have two related questions.

1. I want to create a printer-friendly view of any page of site content.
  The latest documentation has nothing on this yet 
  - but has an empty section showing that this is planned.
   Can a Jahia team member please post a pre-release version of that
information to
   advise on how best to do this.   I am sure this has been done by
   other Jahia users and I really don't want to
   re-invent this, so I would very much appreciate some sample template
code.

2. I want to create a feature to "send this page to a friend" 
  - the contents in printer-friendly format, not just the URL -
   to a specified email address.   Same points as above.

Any help would be greatly appreciated.

thanks,
George.
