The attached document will display columns on screen but not on print (PDF) - I tried with ToT. Firefox is the only one to print colums (other browsers I tried: Opera 9.50.4492, Omniweb 5.6.612.0.92745, Firefox 126.96.36.199 and the latest nightly of Firefox 3)
Since I plan to produce PDF that way, this is a blocker for me, but for the casual user, it is major at worst.

Simple test. Two pages of lipsum to also test where the columns reset (end of doc or end of page)
Column support is only partially implemented. It's completely disabled when printing right now.

columns printing is now implemented properly on Blink since Chromium 49.
Any chance to backport their code (don't even know if it is feasible).
Very interested to see this implemented.
