經常有人在論壇里面詢問水晶報表套打的問題，比如如何精準打印發票，如何配置報表數據源，如何選擇最佳套打方案等等。下面我就來分享一下水晶報表如何套打的一些經驗，說得不全面的地方還請見諒。

水晶報表套打一般分為兩種情況：

1. 清單類打印，在已經印刷好的紙張上打印 ；
2. 單據發票類，單據格式固定，如每張打印5行數據，而且這種格式是已經印刷好的，當然機打發票除外。 

我們以第2種情況為例進行說明，因為第2種會了第1種也自然就明白了。在這里我們使用程序代碼+報表中設置背景圖片的方式來實現。 

1、紙張尺寸類型很難控制客戶端的，那就用A4紙，計算設置較大右邊距和下邊距，以適合你的單據尺寸；

2、頁面設置，精確計算左邊距與上邊距，放好你需打印的組件與不需打印的組件(Top與Left)；

3、窗體上，三個控件：CrystalReport控件、CrystalReportViewer控件和PrintDialog控件，讓CrystalReportViewer控件的ShowPrintButton=false，以免客戶從它啟動打印；

4、在制作報表的時候，把你不需要打印的部分使用圖片代替。

如下圖：

使用了圖片來代替固定數據。如上圖中的“倉儲企業名稱”等標題。

5、報表打印類：

        string m_PrintTypeBarName;

        public string PrintTypeBarName

        {

            get

            {

                if (string.IsNullOrEmpty(m_PrintTypeBarName))

                {

                    return "分撥貨物提貨單";

                }

                return m_PrintTypeBarName;

                

            }

            set

            {

                m_PrintTypeBarName = value;

            }

        }

        /// </summary>

 

        public void HidePicture(ref CrystalDecisions.CrystalReports.Engine.ReportDocument rpt)

        {

            try

            {

                foreach (CrystalDecisions.CrystalReports.Engine.Section section in rpt.ReportDefinition.Sections)

                {

                    foreach (CrystalDecisions.CrystalReports.Engine.ReportObject rptObject in section.ReportObjects)

                    {

                        if (rptObject is CrystalDecisions.CrystalReports.Engine.PictureObject)

                        {

                            //圖片背景

                            (rptObject as CrystalDecisions.CrystalReports.Engine.PictureObject).ObjectFormat.EnableSuppress = true;

                        }

                    }

                }

 

            }

            catch

            {

            }

        }

 

    }

}

6、打印方法：

/// <summary>

/// 打印報表

/// </summary>

/// <param name="strPrintName">打印機名稱</param>

/// <param name="shInt">打印份數</param>

/// <returns>true成功，false失敗</returns>

private bool blnPrint(string strPrintName,string shInt)

{

bool blnPrintScuss=false;

int intCopies=0;

try

{

intCopies=int.Parse(shInt);

}

catch

{

intCopies=1;

}

try

{

                if (ipr == null)

                {                  

                    MessageBox.Show("打印報表出錯");

                    blnPrintScuss = false;

                    return blnPrintScuss;

                }

// m_BillNewRpt.PrintOptions.PaperSize=CrystalDecisions.Shared.PaperSize.PaperA4;

                ipr.HidePicture(ref m_BillNewRpt);

m_BillNewRpt.PrintOptions.PrinterName = strPrintName;

m_BillNewRpt.PrintToPrinter(intCopies,false,1,m_intMaxPage);

blnPrintScuss=true;

}

catch (Exception ex)

{

blnPrintScuss=false;

MessageBox.Show("打印報表出錯:"+ex.Message);

}

return blnPrintScuss;

}

7、套打，只打印數據的效果。如下圖：

8、非套打，全部打印的效果。如下圖：
