I found a link from MS Website, but that is for SSRS 2008 dont know if it might help you, but thought should post it. It might help someone else Heres the link for Enabling and Disabling Client-Side Printing for Reporting Services Regards SD

Didnt really find how to do it in Native Report Viewer (MS Control) so far. therefore, we are looking into third party controls. So far, the reportViewer in ComponentOne (Link) looks promising, and it supports SSRS. Also, AJAX is a prerequisite for this, which might be benifitial. Another one was Telerik which allows you to monitor Client Side Events on server, but the only problem with that is, you have to design reports in their designer only, and thus, no support for ".rdl" files. i am going to look further for about another week, if i find any solution, would definitely let you know.

Any Luck with this? I am trying to achieve the same thing.
