RS 2005, VS 2005 and specifying printer trays

I am trying to build a demo to prove the following can be done with SQL 2005 Reporting Services:

1. Export report as .pdf to file location. - Done

2. Use CSLA business objects with Reporting Services to reuse the object's ability to populate itself. - Done

3. Set certain reports to print from certain trays on a specific printer.  More specifically, for a certain report, I need the first page to print  from Tray 1 and all remaining pages to print from Tray 2.

This is the task I am having problems with.  I am trying to just get the tray selection working now with just a windows app but even if I get that far, will I need to extend RS and write my own print routine   Also, if this report is served to the client via URL, will I be able to specify the printer and tray or will I need a print server to handle this

Thanks.
