Help identifying an OLD anime - a scene where a kid is in a printing press picking metal block letters? I watched it in the early 90s, there is only one scene that I remember and was fascinated by.

For a better understanding of what I mean, it is also known as "movable type" or in Japanese "活版印刷機".

Thank you very much in advance!
