How to convert rdlc report into pdf using iTextSharp?

Hi,
I've a rdlc report which I need to convert into pdf dynamically.
How to do this using iTextSharp?

I tried with normal code like below. but, it throws exception "No printers are installed".
byte[] bytes = ReportViewer1.LocalReport.Render("PDF");
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "application/pdf";
Response.BinaryWrite(bytes);
Response.Flush();
Response.Close();
