Sorry, completely off-topic
Since I repaired daisy wheel mechanisms "back in the day" -- the operation is:
A metal hammer that moves freely inside an electro-magnet. When the wheel is
about to expose the desired glyph, the magnet is fired, causing the hammer
to drive to the wheel. The hammer hits the wheel, and bounces off. It returns
back. IF IT STICKS, THE WHEEL GETS MANGLED. The spoke then impacts the ribbon, and the paper. The spoke then bounces back, and the wheel is moved to the next
desired glyph. You don't want to operate this mechanism without the wheel.
You don't want the hammer to stick. You need the glyph to move -- many times.
It would be useful to "metallize" the wheel -- probably more important at
the center! of the spokes. Two elastic collisions per impact.
Yes, the character would degrade. But the wheel typically lost spokes sooner
than the type became muddy.
All of this because the print speed of 10cps was too slow. Daisy wheels achieved 30+ cps.
