If we subtract the number of 600DPI white pixels from the number of

with 600 DPI, which necessitates, that we saved 240.5 600DPI pixels

DPI instead of 600DPI to print the very large letter A.
Harry, are you saying that at 1200 dpi, you're saving toner over
printing at 600 dpi? That's the reverse of what I've read up to this
point.
Yes, as long as all of the dots use the same amount of toner, ie as long
as the intensity is the same.
If the intensity changes, IMHO, that is not directly related to the DPI,
but some printer makers may take advantage of the smaller dots and take
advantage of those in a "low dpi" mode to lower overall toner use.
