So I looked at the print train and found the order characters appeared

print 100 lines with one I/O command and loop. The characters were in
the same order as the print train so all the magnets could fire at once.
When we ran it, the printer produced a loud screeching sound, unlike the
sounds it made during regular printing. The operators were pretty happy
with their new toy. The only problem is it cleaned the printer too fast
so the fun didn't last long enough.
That could cause an overload on some printers.
