web from generate html on separate pages

Question

In a web form 2010 application, I am creating letters that need to be sent to various customers that are generated in html and are sent to 2 or 3 customers at the at different addresses. However each letter needs to be the same. The only difference is the mailing address. Thus I need each letter to be generated on separate pages. Thus I would like to know what html command can be used to made certain each letter is printed on separate pages. Thus can you tell me what the command would be?
