经常有人在论坛里面询问水晶报表套打的问题，比如如何精准打印发票，如何配置报表数据源，如何选择最佳套打方案等等。下面我就来分享一下水晶报表如何套打的一些经验，说得不全面的地方还请见谅。

水晶报表套打一般分为两种情况：

1. 清单类打印，在已经印刷好的纸张上打印 ；
2. 单据发票类，单据格式固定，如每张打印5行数据，而且这种格式是已经印刷好的，当然机打发票除外。 

我们以第2种情况为例进行说明，因为第2种会了第1种也自然就明白了。在这里我们使用程序代码+报表中设置背景图片的方式来实现。 

1、纸张尺寸类型很难控制客户端的，那就用A4纸，计算设置较大右边距和下边距，以适合你的单据尺寸；

2、页面设置，精确计算左边距与上边距，放好你需打印的组件与不需打印的组件(Top与Left)；

3、窗体上，三个控件：CrystalReport控件、CrystalReportViewer控件和PrintDialog控件，让CrystalReportViewer控件的ShowPrintButton=false，以免客户从它启动打印；

4、在制作报表的时候，把你不需要打印的部分使用图片代替。

如下图：

使用了图片来代替固定数据。如上图中的“仓储企业名称”等标题。

5、报表打印类：

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Easipay.Controls.Printer;

using System.Drawing.Printing;

            return new rptAllocateBLMTHD();

        }

                {

                    return "分拨货物提货单";

                }

                return m_PrintTypeBarName;

                

            }

            set

            {

                m_PrintTypeBarName = value;

            }

        }

    /// <summary>

        /// </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)

                        {

                            //图片背景

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

                        }

                    }

                }

 

            }

            catch

            {

            }

        }

 

    }

}

6、打印方法：

/// <summary>

/// 打印报表

/// </summary>

/// <param name="strPrintName">打印机名称</param>

/// <param name="shInt">打印份数</param>

/// <returns>true成功，false失败</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("打印报表出错");

                    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("打印报表出错:"+ex.Message);

}

return blnPrintScuss;

}

7、套打，只打印数据的效果。如下图：

8、非套打，全部打印的效果。如下图：
