WPF 打印

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");
   }
}
