That band of metal is spinning around faster than you can see. But those hammer banks hit those letters at whatever moment as it spins by and chugs to the next line. That's the chugga chugga chugga noise going on.
From the human perspective that line printer has just printed that entire line instantaneously and has progressed to the next line. But from the microcode level you know there's a hell of a dance going on.
