如何触发服务器端（asp.net）Windows打印对话框？

问题描述

我要生成服务器端的PDF文件，然后在响应要发送的文件（缓冲，fileName-任何可能工作），并显示一个打印对话框询问用户打印生成的PDF文件。

I want to generate a PDF file on server side, and then in response want to send that file (buffer,fileName- whatever may work) and show a print dialog to ask user to print the generated PDF file.

我想是这样的下方。不过，这并不触发window.print（）对话框。

I tried something like below. But it does not trigger window.print() dialog.

   public static void ForcedPrint(HttpResponse response, byte[] buffer, string fileName, string fileExtension) {
      response.Clear();
      response.Buffer=true;
      response.Write("<script>window.print();</script>");
      response.Charset="";
      response.Cache.SetCacheability(HttpCacheability.NoCache);
      response.ContentType="application/pdf";
      response.BinaryWrite(buffer);
      response.Flush();
      response.End();
    }

可有人请帮助我？
的功能我期待的是，我应该能够创建在服务器上的PDF文件，并针对用户应该得到一个对话框来打印生成的文件。

Can someone please help me with this?The feature i am looking for is that i should be able to create PDF file on server, and in response user should get a dialog to print the generated file.

在此先感谢。

推荐答案

您需要嵌入PDF中的HTML文档中说，在一个名为DIV thePDF ，并在文件中的JavaScript代码，你需要调用

You need to embed the PDF in the HTML document, say in a div called thePDF and in JavaScript code in the document, you need to invoke

thePDF.printWithDialog()

这似乎将是的Adobe Reader插件的打印对话框，而不是浏览器的打印对话框中的对话框;这将允许在打印前的页面等选择。

The dialog that appears will be the Adobe Reader plugin's print dialog rather than the browser's print dialog; this will allow selection of pages etc. before printing.
