Silverlight 4 and printing reports?

Question

Hi I'm wondering how we should think strategically about silverlight and reports.

We have requirements that our customers wants the reports in several formats such as pdf, excel, just print.

I have worked with ActiveReports earlier but what I know they aren't supporting Silverlight.

So my first question do we need any third part component to accomplish this or can we do it with Silverlight 4 as it is?

Is there any third part component for Silverlight 4?

Should we do this at the server side and then transfer the generated report file with a third part component?
