Firebug is an excellent tool to to show a screen media CSS for some HTML element, but is there a way to look at the print media CSS too? Or is there any other tool to see the print media CSS?

What about Web Developer Toolbar?

when installed go to CSS -> Display CSS by media type -> Print
I would have never expected this to work, but it does. Install -both- the 1.5 beta of Firebug and Web Developer. When you choose the print css from Web Developer, the tools in Firebug suddenly work on the new print version of the page. So far I haven't found any problems with running both at the same time.
Use the Web Developer plug in. Then you can choose from the CSS menu which media you want the page to display as.
You might want to take a look at the webdeveloper toolbar - it allows you to select what CSS you want to see. In conjunction with firebug, it should be possible to see the print media CSS.
In Firefox (and some other browsers), you can see a static display of the print stylesheet by using Print Preview. It's nowhere near as useful as the web developer toolbar, but it can also help you understand what is going to be printed.
Web developer toolbar has one big drawback for CSS debugging though: every time you refresh the page it reverts to the screen stylesheet.
What I tend to do these days is temporarily switch the media of the print stylesheet to screen while I'm developing, and then switch it back before going live.
Firefox 68 added a button to "Toggle print media simulation for the page" to the Rules View of the Page Inspector (Bug 1534984):
There's a video of how to use the button in "View @media rules for Print" section of the "Examine and edit CSS" page.
