//Set the printer name to print the report to. By default the sample
//report does not have a defult printer specified. This will tell the
//engine to use the specified printer to print the report. Print out
//a test page (from Printer properties) to get the correct value.

System.Drawing.Printing.PrintDocument printDocument = new System.Drawing.Printing.PrintDocument();
crReportDocument.PrintOptions.PrinterName = printDocument.PrinterSettings.PrinterName;

//using the arguments.
