A line printer sounds nothing like a dot matrix printer. They're much, much louder, and it's a continuous buzzing noise, like a chainsaw. Also, the output appears at a similar speed to a dot matrix doing a form feed. While the sound of a dot matrix printer can be kind of therapeutic - I remember debugging by printing, where the sound of printing and the time waiting could be used to mentally debug the problem, so you almost knew where the bug was without even looking at the print out, a line printer is the complete opposite as it's so loud it's distracting and the output gets spat out so quickly you don't have much, if any thinking time!
