Problem in Printing and Reporting Crystal Report

Question

Hai,
I'm Using VS2010 and SQL Server.
The below code is I have used in my page for Crystal report
protected void Page_Load(object sender, EventArgs e)
//Here I retrieve User Name from another page using session
        lblUserName.Text = Session["empName"].ToString();
    protected void btnReport_Click(object sender, EventArgs e)
        ReportDocument rdoc = new ReportDocument();
        SqlConnection con = new SqlConnection("Data Source=SERVICETEAM-PC;Initial Catalog=salaryReg;User ID=sa;Password=kavi");
        con.Open();
        SqlCommand cmd = new SqlCommand("SalaryEarnings1", con);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataTable dt = new DataTable();
        da.Fill(dt);
        rdoc.Load(Server.MapPath("CrystalReport.rpt"));
        rdoc.SetDataSource(dt);
        rdoc.SetParameterValue("empName", lblUserName.Text);
        CrystalReportViewer1.ReportSource = rdoc;
        CrystalReportViewer1.DataBind();
        con.Close();
this is the code I've used to generate crystal report in one of my asp.net web site under button click event. This create report without any errors but after that when
i click print button on crystal report tool bar print function is not working and when try to do Exporting the report it asks for further details by giving a window like this
