推荐答案

这code将在服务器而不是客户端上运行。在开发服务器和客户端是同一台计算机，本地工作站。一旦部署完毕，这将在服务器上执行，而不是用户的本地工作站。

this code will run on the server not the client. while developing the server and client are the same machine, your local workstation. Once deployed, this would execute on the server, not the user's local work station.

您可以使用JavaScript打开打印对话框

you can open a print dialog box using javascript

window.print();

不过，将打印整个webapge，而不是专门的文件

However that will print the entire webapge, not the document specifically.

如果您想只打印PDF，需要流的文件浏览器（而不是整个网络表格）。然后，用户可以充分利用在Adobe Reader内在本地打印选项的优势。有许多例子网上有关如何将文档传输到客户端的浏览器。

If you would like to print only the PDF, you need to stream the file to browser (not an entire webform). The user can then take advantage of the native print options within the adobe reader. There are many examples online about how to stream documents to the client's browser.
