Printing RDLC Report Using Asp.net C#

Question

Hello everyone, hope someone can give me the correct code. 

 

I am trying to print a RDLC report without preview. Below is my code but does not work. The error says "Exception Details: System.NotSupportedException: The given path's format is not supported."

 

protected void PrintPos(object sender, EventArgs e)
        {
            string sql = "spGet_SalesDetails_A4Printing";
            var dt = GetDataTable(sql);
            LocalReport report = new LocalReport();
            string path = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);
            string fullpath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Remove(path.Length - 4) + @"\PosPrinting\PrintingPos.rdlc";
            report.ReportPath = fullpath;
            report.DataSources.Add(new ReportDataSource("dsProduct", dt));
            int printQty = 2;
            for(int i = 0; i < printQty; i++)
            {
                PrintToPrinter(report);
            }
        }
