You can configure the printer using the COM port and communicate the port to print your data. Arrange the data in Grid view and print the same. Sample Code: protected void PrintCurrentPage( object sender EventArgs e) { GridView1.PagerSettings.Visible = false ; GridView1.DataBind(); StringWriter sw = new StringWriter (); HtmlTextWriter hw = new HtmlTextWriter (sw); GridView1.RenderControl(hw); string gridHTML = sw.ToString().Replace( \  ' ) .Replace(System. Environment .NewLine  ); StringBuilder sb = new StringBuilder (); sb.Append(   ); sb.Append( window.onload = new function(){ ); sb.Append( var printWin = window.open('' '' 'left=0 ); sb.Append( top=0width=1000height=600status=0'); ); sb.Append( printWin.document.write(\ ); sb.Append(gridHTML); sb.Append( \); ); sb.Append( printWin.document.close(); ); sb.Append( printWin.focus(); ); sb.Append( printWin.print(); ); sb.Append( printWin.close();}; ); sb.Append(   ); ClientScript.RegisterStartupScript( this .GetType() GridPrint  sb.ToString()); GridView1.PagerSettings.Visible = true ; GridView1.DataBind(); } Mark as answer if applicable.
