NCR used a teletype printer on one Serbs of mainframes for the console
output. Forget which model, but was a disaster as a console printer. Was
designed to turn on and print an incoming message, then turned off the
motor. Very light duty printer. Our use turned on the motor and the shaft
never stopped running. Those oil title bushings would eventually cut the
shaft so there was a great play in the bearings. Was a pain in the ass to
change the shaft and align all the cams.

IBM broke the printing part off the back off of a Selectric
typewriter, beefed it up a bit and used it as a console printer for
close to a decade before they figured out the wire matrix printers.

They were not made to print that much either. Everyone learned how to
work on them ... some better than others.

We went to those on a later system. selectric B. Later dot matrix.
