Ahhh, the IBM 1403 train printer...  It could slew paper so fast that by 
the time that the operator realised that there something was wrong with 
that print job, it has chewed through an entire box...

You also quickly learned to not rest your coffee cup upon it, as it would
automatically open when out of paper.

Best printer I've ever used.
