Print it

It would be nice to be able to preview the result before printing it, so the question still stands.

Cmd-P brings up a preview immediately? Laid out on A4, like it'll print, unlike your arbitrarily-sized browser window.

The layout of the page is going to be a function of the paper size you put it on and the orientation of that paper. Use the print preview.

I used dev tools to nuke it, but it’s really annoying

Print it :)
