My dad used to run a printing shop till the late 80s when he passed away. I think the bulk of his business was producing 10k-100k copies of books/documents for people at a lower unit code than any other methods. Once those machines were setup, they could crank out 3-4 copies a second. He used to do a lot of the game manuals for a video game company and they used to give him finished video games every year for us kids to play.
