Mail Form output to PDF

Hello Experts,

We are using mail forms (html) for correspondence in the Interaction Center.

We have a requirement to output the mail form to:

1. Email

2. PDF (for mass printing/mailing)

Of course the email options is standard SAP.  This is no problem.

The second requirement to output to PDF is more complex.

I would like to know, what is the best way to take the HTML output from the Mail Form and convert to a PDF format?

Some options I can think of include:

1. Output the html to spool, then convert spool to PDF.

2. Convert html to OTF, then convert OTF to PDF. (Is this possible?)

3. Other options?

Thank you!
