DevExpress一直备受关注，鉴于许多网友反映，对DevExpress所涉及到的打印不是很清楚，现特意为大家做了一个小结，内容分为：

1、DevExpress 打印服务调用

if (_WebOrderModel.OrderNo.ToString().Trim().Equals("") == true) 
                return; 
            string OrderNo = _WebOrderModel.OrderNo; 
            //client.GetOrderNOAsync(orderno);  
            DocumentPreviewWindow preview = new DocumentPreviewWindow(); 
            ReportPreviewModel model = new ReportPreviewModel(); 
            //读取ReportService服务地址 
            model.ServiceUri = SystemControl.Super.GetAppSetting("ReportService.BaseURL"); 
            model.ReportTypeName = "Com.B2B.Admin.Report.XtraOrderDetail"; 
            model.Parameters["Weborderno"].Value = OrderNo; 
            //model.AutoShowParametersPanel = false;            
            preview.Model = model; 
            preview.Model.CreateDocument(); 
            preview.ShowDialog();
