Create script to generate letter from php forms

I am looking for a script that will take values from fields in a PHP form and automatically generate the letter that will allow a user to print it, and save it. The script must be customizable to allow me to customize it to the exact names of the fields. This must also transfer calender dates. The forms are already populated and the data will come from the user input. tehre are three total forms, all in PHP. The letter must be able to be seen on the website, allowing the user to print the letter, without printing any of the html headings and allow for our logo to be placed at the top right of the letter. It should include the sender's name at the bottom of the letter for the closing.
