Report report = new Report();
var assembly = System.Reflection.Assembly.GetExecutingAssembly();
string path = Path.Combine(Path.GetDirectoryName(assembly.Location),"Report", "Print1.frx");
report.Load(path);
RequestParams requestParams = obj as RequestParams;
List<RequestParams> requestParamsList = new List<RequestParams>();
requestParamsList.Add(requestParams);
report.RegisterData(requestParamsList, "requestParamsList");
report.PrintSettings.ShowDialog = false;
report.PrintSettings.Printer = requestParams.printer_name;
report.Print();
report.Dispose();
