Controling the printer from ASP.NET

Is there any way to do this by using an activeX control or anything else?

The reason I want to this is that I want to print a pdf file that I generate
on the fly (with Reporting Services) without actually starting Acrobat
Reader. I want to automatically set the printer, set the size of the paper
and then send the command to the printer.

I know I can easily do this in Windows applications, but in ASP.NET, is it
possible?

Thank you for your help.
