... presuming that a big image will always be scaled (reduced) to fit
the screen. But the difference will easily be seen when looking at a
portion of the unscaled image (or when the image is just scaled to 0.5
of the original size, for instance).

Yes, I forgot to mention that on my previous message. Although
algorithms used after scanning should not care about the specific
resolution, scanning and printing equipment obviously have some ideal
resolution choices related to its physical characteristics, as you
explained.
