C#求把word文档内容实现自己的窗体的打印预览方法

C#把word的内容读取出来并显示在自己建的窗体的打印预览界面中，同时实现打印，C#的printDocument都要把打印的东西画成图片的，有没有其它办法？如果没有，如何控制文字好格式（不需要字体颜色等，只要控制好每一行的字数和排版像word内的，如第一行A字结束，在图片中也是一样）

1、预览时、可弹出层、层进行内容绑定
 2、层上放置打印按钮、页面设定参见下面代码！  
  /// <summary>
  /// 点击打印
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  private void btnPrint_Click(object sender, EventArgs e)
  {
  //this.m_pageSettings.Landscape = true;
  //获取当前默认打印机
  m_printDocument = new PrintDocument();
   
  //设置要使用的打印机的名称
  this.m_printDocument.PrinterSettings.PrinterName = cmbSelectPrinter.SelectedItem.ToString();
  if (this.m_printDocument.PrinterSettings.IsValid)
  {
  #region 页面设置
  //获取当前报表的所需的页面设置
  ReportPageSettings rptPageSettings = this.rptView.LocalReport.GetDefaultPageSettings();

  this.m_pageSettings.Margins = rptPageSettings.Margins;
  this.m_pageSettings.PaperSize = rptPageSettings.PaperSize;
  //页面边距设定
  this.m_pageSettings.Margins.Bottom = rptPageSettings.Margins.Bottom;
  this.m_pageSettings.Margins.Left = rptPageSettings.Margins.Left;
  this.m_pageSettings.Margins.Right = rptPageSettings.Margins.Right;
  this.m_pageSettings.Margins.Top = rptPageSettings.Margins.Top;
  //页面尺寸设定
  PaperSize paperSize = new PaperSize();
  if (this.m_isLandSapce)
  {
  //横向
  paperSize.Height = rptPageSettings.PaperSize.Width;
  paperSize.Width = rptPageSettings.PaperSize.Height;
  }
  else
  {
  paperSize.Height = rptPageSettings.PaperSize.Height;
  paperSize.Width = rptPageSettings.PaperSize.Width;
  }
  paperSize.PaperName = rptPageSettings.PaperSize.PaperName;
  paperSize.RawKind = rptPageSettings.PaperSize.RawKind;
  this.m_pageSettings.PaperSize = paperSize;
  //打印方向
  this.m_pageSettings.Landscape = m_isLandSapce;
   
  #endregion 页面设置
  //根据打印机物理边距(可打印区域距离纸张边距)重新调整页边距，以适应不同的打印机
  unchecked
  {
  this.m_pageSettings.Margins.Left -= (int)m_printDocument.DefaultPageSettings.HardMarginX;//左边距减去打印机可打印区域边距
  this.m_pageSettings.Margins.Top -= (int)m_printDocument.DefaultPageSettings.HardMarginY;//上边距减去可打印区域边距
  }

不想用报表不行吗？安装个报表搞得太麻烦了，其实我 的都是动态生成的word文件，但预览的时候不希望直接打开个word给用户看，所以不想调用word本身的打印预览

。。。我今天也在做这个，也不想用报表，想直接打窗体上的内容
