水晶报表实现套打

对于套打的情况，一般出现在以下两种情况：1：清单类打印，一般可能是已经是在已经印刷好的纸张上打印2：单据发票类，一般单据格式固定，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;using System.Collections.Generic;using System.Linq;using System.Text;using Easipay.Controls.Printer;using System.Drawing.Printing; namespace Warehouse.Report{    public class ReportAllocateBLM : ReportBase, IPrintReport    {        // <summary>        /// 生成报表对象        /// </summary>        /// <returns></returns>        public object Report()        {            return new rptAllocateBLMTHD();        }             /// <summary>        /// 打印预览, 设置报表数据的方法：        /// </summary>        /// <param name="rpt">报表</param>        /// <param name="reportData">需要打印的数据</param>        /// <param name="boolBackgroupPic">是否打印背景图片</param>        public void PrePrint(ref CrystalDecisions.CrystalReports.Engine.ReportDocument rpt, object reportData, bool boolBackgroupPic)        {            ProtionOutHeadReport info = GetDataSet(reportData);

       }        ///<summary>        ///生成报表所需要的DataSet        ///</summary>        ///<param name="reportData">由界面中传过来的数据</param>        ///<returns></returns>        private ProtionOutHeadReport GetDataSet(object reportData)        {            ProtionOutHeadReport outBillDs = new ProtionOutHeadReport();

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。
