      During the late 80's the company I worked for (Microcomm) built
      news wire boards for dot matrix printers used in the new industry.
      One nite while listen to NBC-NY News I could hear in the background
      one of our printers priting away like mad (Okidata 82 slimline, yes I
      knew the sounds of each type). And they way I knew was that the story
      on the line was 3 bells. I don't recall the story but it was important.

        I believe it. It's not just pins firing, but it's the acoustics of the printer box (and type of foam Rich used), the size and type of the drum or cylinder (what ever it's called) that the pins are striking against, the solenoids themselves and the speed that the print head is moving at.

        So, like a musician knows the difference between a cheap instrument and a quality instrument, I'm sure you know your printer! We should play a game, name that printer... :)

        In the security field, they used something like a ticker tape recorder to receive alarms in the central station. The older guys knew the address of the alarm by the sound.
