It is conceivable to me that dots of different sizes could be printed. My recollection is that that is what HP does, but I don't have the manual handy. Since a printed dot is not the same as a particle of toner, there could be lots of ways of changing the number of toner particles in a dot, hence its intensity. There is no reason in principle why the same trick could not be done with color, though, again, I don't know if anyone does it.
