How to uncheck the center the page option in layout of the print?

Hi Guys,

I have developed an application for billing purpose and My client is using Thermal Printer for Invoice Billing. My Client has WeB TH400 Thermal Printer and Whenever client go for print he has to follow this path to print

Code as below

ds.Tables.Clear();
           crystalReportViewer1.Refresh();
           try
           {
               adp = new SqlDataAdapter(query, con);
               adp.Fill(ds, "order");
               adp1 = new SqlDataAdapter(query2, con);
               adp1.Fill(ds, "BillDetails");
               ReportDocument rd = new ReportDocument();
               int count = ds.Tables["BillDetails"].Rows.Count;
               if(count < 5)
               {
                   rd.Load(Application.StartupPath + "\\crOrderReport3.rpt");
               }
               else if(count > 10)
               {
                   rd.Load(Application.StartupPath + "\\crOrderReport.rpt");
               }
               else
               {
                   rd.Load(Application.StartupPath + "\\crOrderReport1.rpt");
               }
               rd.SetDataSource(ds.Tables["order"]);
               foreach(ReportObject repOp in rd.ReportDefinition.ReportObjects)
               {
                   if(repOp.Kind == ReportObjectKind.SubreportObject)
                   {
                       string SubRepName = ((SubreportObject) repOp).SubreportName;
                       ReportDocument subRepDoc = rd.Subreports[SubRepName];
                       subRepDoc.SetDataSource(ds.Tables["BillDetails"]);
                   }
               }

               crystalReportViewer1.ToolPanelView = CrystalDecisions.Windows.Forms.ToolPanelViewType.None;


               crystalReportViewer1.ReportSource = rd;

               //crystalReportViewer1.DataBind();
           }
           catch(Exception ex)
           {
               MessageBox.Show("Error occur during Report");
              // MessageBox.Show(ex.Message);
           }

Thank You
