Set up batch print on web page

An existing website has a folder with a number of PDF forms that the client uses in business. A .asp web page lists the contents of the folder, using VBScript and a MSSQL db. On the web page, we would like to have the ability to select a multiple number of the pdf's to print (rather than opening each one and printing it out of Acrobat). We would like to be able to select several individual files or a predetermined "package" of files, based on an assigned "type" indicator (already in place). It is my understanding that this batch printing functionality is available in .NET, so I am looking for someone knowledgable in this area to create the solution. However, if there is a simpler or better way of reliably producing the desired result, I am open to suggestions. The website is on a Windows server, db is MSSQL 2005. I need a very fast turnaround on this project (within 1 week).
