实现的功能：预览的时候数据和格式都可以看到，打印的时候只打印数据，这应该是套打功能最基本的要求。

基本思路：使用工具栏的printbarmanager控件，在printcontrol中显示XtraReports。创建两个XtraReport，一个是完整显示（xr），另一个只显示部分数据（xr_report）。打印的时候在printcontrol中显示xr_report，xr_report打印完毕时（PrintingSystem.EndPrint事件）换回xr。

关键点：设置xtrareport的格式后，还要执行CreateDocument()

代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using DevExpress.XtraEditors;
using DevExpress.XtraReports.UI;
using DevExpress.XtraPrinting.Preview;
using DevExpress.XtraPrinting;
using DevExpress.XtraPrinting.Control;

namespace WindowsFormsApplication4
{
public partial class Form1 : Form
{
XtraReport1 xr = new XtraReport1();
XtraReport1 xr_other = new XtraReport1();
public Form1()
{
InitializeComponent();
xr_other.PrintingSystem.EndPrint += new EventHandler(PrintingSystem_EndPrint);
}

void PrintingSystem_EndPrint(object sender, EventArgs e)
{
printControl1.PrintingSystem = xr.PrintingSystem;
}

private void Form1_Load(object sender, EventArgs e)
{
printControl1.PrintingSystem = xr.PrintingSystem;
xr.CreateDocument();
xr_other.xrTable1.Borders = BorderSide.None;
xr_other.xrLabel1.Visible = false;
xr_other.CreateDocument();
}

private void printPreviewBarItem9_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
printControl1.PrintingSystem = xr_other.PrintingSystem;
}

private void printPreviewBarItem8_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
printControl1.PrintingSystem = xr_other.PrintingSystem;
}
}
}
