A WordPress plugin to add print-only css styling. I came across a need to make this plugin when I didn't have FTP/SFTP/Git access to a site.
If you'd like to make this fit for your site, you just need to alter the styles inside print-style-css/css/style.css
Helpful Tip!
If you want to test the print css changes in Chrome, instead of constantly [right_click] -> Print you can click the three black dots inside your inspector controls and go to More tools -> Rendering -> Emulate CSS media -> Print and that will emulate what your web page would look like if it was printed.
