问题：
I am working on developing a website and need to work on the print view. 我正在开发一个网站，需要处理打印视图。 Typically when I have layout issues I use Chrome's Element Inspector. 通常，当我遇到布局问题时，我会使用Chrome的Element Inspector。 However this does not exist in print preview mode. 但是，这在打印预览模式下不存在。
Is there a Chrome plugin or some other way to change your viewing medium within chrome itself, to view a page as a printer would? 是否有Chrome插件或其他方式来更改Chrome本身的查看媒体，以打印机的形式查看页面？ I suppose it doesn't have a be a Chrome specific solution, but that is my primary browser so it would be nice to have an in-browser solution. 我认为它没有特定于Chrome的解决方案，但这是我的主要浏览器，所以拥有一个浏览器内的解决方案会很不错。
Right now I'm focused just on the print preview medium, but it would be ideal to be able to change to any of the supported media types (ie all/braille/embossed/handheld/print/projection/screen/speech/tty/tv). 现在我只专注于打印预览媒体，但是能够更改为任何支持的媒体类型（即所有/盲文/浮雕/手持/打印/投影/屏幕/语音/ tty /电视）。
