Firefox Minimum Print Font Size

I've been frustrated with font sizes when I print documents and playing games with zoom level, etc. But it turns out Firefox has a good, general solution: no more playing around.

Firefox allows one to set minimum print font size. In limited testing, it works well, as it should, since the browser should be able to re-flow text for changing font sizes. Other browsers probably have some similar mechanism, but this is for Firefox:

Preferences | Content | Fonts&Colors | Advanced | Minimum Font Size

I set mine to 11. It does sometimes use more paper, but several times I've seen a printout, and tossed it directly into recycling and tried again.

Alternatively for nerds: Open about:config, find the variable font.minimum-size.x-western, and set it to your preferred minimum font size.
