Apply 'no columns' print style to Guide/Detailed Guide

[matthillco]

What

Add the new gem-print-columns-none print class to the layouts in Guides and Detailed Guides, to collapse columns on print. Trello

Why

When printing various page types, the 2/3rds + 1/3rds column layout causes issues with cropped content and a generally poor printing experience because the full page isn't used. By selectively collapsing floated columns, we can avoid most of these issues and improve the printing experience by using the full width of the page.

Looks good to me 👍

Slightly off topic, is the contrast on these numbers good enough for print?

Also why are my links when I print blue, and yours grey? Is that just your printer settings set to greyscale?

Nice spot, yep I have this in my backlog of other fixes that still need doing, this one slipped through the net.

That's curious, links should print as black for everyone, we should compare our setups to find out the differences.
