As of Chrome 48+, you can access the print preview via the following steps:
Open dev tools – Ctrl/Cmd + Shift + I or right click on the page and choose 'Inspect'.
Hit Esc to open the additional drawer.
If 'Rendering' isn't already being show, click the 3 dot kebab and choose 'rendering'.
Check the 'Emulate print media' checkbox.
From there Chrome will show you a print version of your page and you can inspect element and troubleshoot like you would the browser version.
