Question

XPS打印机允许我们创建xps文件，无论是来自图像还是txt或doc文件。

我想在c＃中以编程方式执行相同操作。

如何将文件发送到xps打印机并让打印机将其转换为.xps文件？

有什么想法吗？

我谷歌这个但到目前为止还没有找到太多。

也可以使用打印队列打印到XPS文档编写器，但它始终显示文件对话框。

请参阅下文转换和打印到XPS文件的其他替代方法。

以编程方式将文件转换为XPS

这并不像你希望那里的许多用户尝试过那么简单，并且有许多不同的方法来实现它们并非最好。

将文档转换为XPS的一种方法（最简单的方法）是使用WORD 2007+ API来完成它。请参阅下面的MSDN论坛question

要使用Word 2007以编程方式将docx转换为xps，请参阅 Word对象模型参考中的Document.ExportAsFixedFormat （http://msdn2.microsoft.com/en-us/library/Bb256835.aspx）。然而，由于这是服务器端方案，您应该注意KB 257757 Office的服务器端自动化的注意事项（参见 http://support.microsoft.com/kb/257757）。

将图像打印到XPS

您可以使用以下代码轻松地将图像打印到XPS文件。下面的代码是WPF示例，您传递给write方法的图像需要包装在画布中，请参阅此帖子以获取示例：http://denisvuyka.wordpress.com/2007/12/03/wpf-diagramming-saving-you-canvas-to-image-xps-document-or-raw-xaml/

XpsDocument xpsd = new XpsDocument("C:\\YourXPSFileName.xps", FileAccess.ReadWrite);
System.Windows.Xps.XpsDocumentWriter xw = XpsDocument.CreateXpsDocumentWriter(xpsd);
xw.Write(YourImageYouWishToWrite);

请参阅下面的扩展示例：

public void Export(Uri path, Canvas surface)
{
  if (path == null) return;

  // Save current canvas transorm
  Transform transform = surface.LayoutTransform;
  // Temporarily reset the layout transform before saving
  surface.LayoutTransform = null;

  // Get the size of the canvas
  Size size = new Size(surface.Width, surface.Height);
  // Measure and arrange elements
  surface.Measure(size);
  surface.Arrange(new Rect(size));

  // Open new package
  Package package = Package.Open(path.LocalPath, FileMode.Create);
  // Create new xps document based on the package opened
  XpsDocument doc = new XpsDocument(package);
  // Create an instance of XpsDocumentWriter for the document
  XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
  // Write the canvas (as Visual) to the document
  writer.Write(surface);
  // Close document
  doc.Close();
  // Close package
  package.Close();

  // Restore previously saved layout
  surface.LayoutTransform = transform;
}

有第三方工具允许您将PDF和其他文件格式打印到XPS。

打印XPS文件

可以以编程方式打印XPS文档至少对于此解决方案，您将需要.Net 4。

下面的示例使用WPF中的“打印”对话框以及System.Windows.Xps和System.Printing中的一些类。

下面的代码会将Xps文件打印到系统上的默认打印机，但是如果要打印到其他打印机甚至打印到打印服务器，则需要在打印对话框中更改PrintQueue对象。

使用System.Printing命名空间非常简单。

请参阅下面的示例。

请记住，因为它正在使用WPF对话框，所以它需要在STATThread模型上运行。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Printing;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Controls;
using System.Windows.Xps.Packaging;

namespace ConsoleApplication
{
    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            PrintDialog dlg = new PrintDialog();
            XpsDocument xpsDoc = new XpsDocument(@"C:\DATA\personal\go\test.xps", System.IO.FileAccess.Read);
            dlg.PrintDocument(xpsDoc.GetFixedDocumentSequence().DocumentPaginator, "Document title");

        }
    }
}
