1978 – 'Farewell, Etaoin Shrdlu'

I recommend another documentary for anyone interested in the history of the Linotype:

Used to be on Netflix, but not presently.

Despite the year in the title, this is really a (2014) obituary for a New York Times Linotype operator who died in 2014 and was profiled in a 1978 documentary.
