For something even madder, look at the design of the original Radio Shack 'Line
Printer' which was
actually a Centronics something-pr-other (733?). This thing (which is not a line printer
at all) has a belt
running across the chassis with a motor continuously driving it (a shaded pole motor I
think). Solenoids
on the printhead carriage grab the top or bottom run of the belt depending on which way
the carriage
is to move.
Is that the same screwball printer that has a metal platen spinning behind the paper with
horizontal raised lines on it, and a single vertical striker in the printhead that strikes
at the moment when the platen and striker intersect at the desired X/Y location of the dot
to be printed? I've considered buying one just to hear what it sounds like.
