1、利用shell命令，调用进程打印

string pdfPath = “testPrint.xps";

Process proc = new Process

 {

      StartInfo =

       {

          CreateNoWindow = false,

          WindowStyle = ProcessWindowStyle.Hidden,

          UseShellExecute = true,

          FileName = pdfPath,

          Verb = "print"  //Verb(谓词)，它可以通过FileName属性的扩展名（不管FileName存不存在）并查询注册表返回相应文件类型的Shell菜单

                                                     命 令，常见有“print”打印，“open”打开，“edit”编辑，“runas”管理员身份运行

                                                       

         }

   };

    proc.Start();

    //proc.WaitForExit();

    proc.Close();

注：此方法适合打印已存在的文件。

2、利用PrintDialog打印xaml页面

 FixedPage printPage = (FixedPage)Application.LoadComponent(new Uri(@"../Print.xaml", UriKind.Relative));

 PageContent pageContent = new PageContent();

 FixedDocument fixedDoc = new FixedDocument();

 fixedDoc.DocumentPaginator.PageSize = new Size(96 * 8.5, 96 * 11);

 ((IAddChild)pageContent).AddChild(printPage);

 fixedDoc.Pages.Add(pageContent);

 dialog.PrintDocument(fixedDoc.DocumentPaginator, "打印报告");

 

如果需要预览就要用到DocumentViewer控件，设置Document即可。

 

3、利用PrintDialog打印界面控件

private void Button_Click(object sender, RoutedEventArgs e)

{

    PrintDialog dialog = new PrintDialog();

    if (dialog.ShowDialog() == true)

   {

        dialog.PrintVisual(grid, "PrintTest");

   }

}
