如何在浏览器中停止打印到文件？

Question

我正在开发一个Web应用程序，该应用程序在Web浏览器中显示pdf文件，并且我希望限制打印此文档。是否有任何方法可以停止打印到文件，因为我只需要通过物理打印机打印即可。

Answer 1

Since PDF can be downloaded to computer and than opened with any PDF reader, it means you can't prevent certain functionality of ALL readers.

You still can have your own interface that allows or disallows some functions, but I think printing to file is also browser stuff that can't be controlled using JS.

Answer 2

go through css3 media queries in MDN. You must find print media type in the page. It has some restrictions on page printing. https://developer.mozilla.org/en-US/docs/Web/CSS/@media or https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Getting_started/Media
