The revolution has already occurred in some places. If I need a print job there's a printer within five minutes walk from me, I actually have a couple of places I could walk to. It's less than 10 yen for black and white, 50 to 80 yen for color.
I've put over 10000 of pages through my $150 laser printer at a consumables cost of about $0.02 per page, resulting in an amortized cost (including the printer) of $0.035 per page.
