Recommendations: Printing documents via .NET

Hi all,

I have just recently completed a project in ASP.NET where people can add information to a database and then view reports on the saved info. Nothing too complex but everyone is happy ;)

Now, it seems that they want to extend the application and allow batch printing of word documents. Also, they want information inserted into each document that is retrieved from the database

So, basically they want users to be able to select a document from a centralised document store (no problem) and a list of people from the database.

For each person retrieved from the database insert their details into the document and print the document to the local printer of the user.

Now, this application is run Intranet wide so there is no single printer.

Suggestions more than welcome about tackling this one :)

Thanks
