I think Art was saying that the relationship between pixels in the file and
dots on the page isn't clear cut because the dither pattern used by the
printer driver is random and therefore undoes some of the regularity of the
pixels.  The print ends up looking smoother than say a monitor image because
the printer shadings aren't constructed as rectilinear sharp edged objects
but random spots of colour.
