bulk PDF printing in client printer

Question

 
Hi All: I'm working on a mini document management system(Web Application in .net 4.0) that will associate specific PDFs on a server with particular users, so that user could pull up a checkbox list of PDFs that apply to them,  check off the ones they want to print, and click "print" to have them all print in one shot...is there any way to do that?
In client machine whatever printer is configured print out should come form that printer.
Please help me ...
i am breaking my head but not getting any proper solution.
Its urgent?
Please provide some sample code if possible
Help me..
Thnx in advance
