A childhood belief about technology

When I was younger I was convinced that the computer and printer were operated my hundereds of little men (never women). They lived in the computer and would use stamps to put the letters on the screen. When you printed something the little men would run back and forth to the printer telling the little men in the printer what to write. The men in the printer would then write on the paper very carefully (they all had really good handwriting). I can't quite figure out why the men would use stamps on the computer screen but would write on the actual paper.
