"I learned a thing long time ago, and it was:
Once you print something, you
can’t get it back.
On the surface, this statement doesn’t make any sense. Scanners are cheap, and
in 2021 some digital cameras are as good as scanners, too. Optical character
recognition is so fast that it can happen in real time, leaving enough
processor power for simultaneous translation to a different language. And I
myself bragged about scanning almost 400 printed items and putting them up on
the Internet Archive the other day.
But something happens to photos in particular when they get printed. Pixels
only make sense on displays. To survive in real life, pixels have to get
translated into halftones – complex patterns of translucent cyan, magenta,
yellow, and black dots that overlap, vary in size, and are rotated at strange,
yet deliberate angles."
