You carry on being unconvinced, and leave those of use doing it to see
what we do see with our peepers. (I use a watchmakers Loupe).

It doesn't work like that, the dots are the same size, but with the lower
resolutions there are less of them in a given area. (The figures kinda
give it away).

And no, if you print at anything less than max res you don't get a black
square, you get an increasingly greyer square, and if you use the drivers
Economode, you get a *very* light grey and spotty square.

I guess, if you have money to burn, then use your colour Laser, even for
B&W.

Our Laser is only ever used for B&W documents, so it would be a waste of
lolly using a colour Laser.
In the home office environment we have to keep control of the consumables.

Printing draft in lower res does save toner.
