Yeah those printers were noisy as hell. I remember my first personal laser printer for home was an HP Laserjet 3. All metal in those days and weighed a ton. Cost a ton too. But printed so fast and the quality was so nice it was worth every penny. Now everything is all plastic, cheap, and print better and usually faster for a tenth the price. Even with the cost of toners or inks. But those dot matrix things were a nightmare to work with.
