Toner saving by choosing another font

font
#1

In another discussion, @nico mentioned the impact of the font choice when it comes to rendering documents from OOXML to ODF and PDF.
This made me think, are there more reasons to (re)consider the ‘default’ font for your organisation?
Could saving toner be one of them? And, IS it one for your organisation?
I was looking for some more info on toner/ink usage and found this topic on Quora:

I am curious about your experiences with this…
