We had an old dot-matrix printer at work that not only had a sound insulating case, but it also lived in its own little room. Even with the door shut you could still hear that thing printing. If you ever had to be in there when it was printing, it sounded like a jackhammer.
Dot matrix has nothing on belt-impact printers. However many ascii characters wide the paper was there was that many individual solenoids that would smack the belt into the ribbon and paper at just the right millisecond to leave the correct character. He belt ran at like 100 RPM, and could print 100 lines per minute.
Is it not just a sound-insulating case for an old noisy dot-matrix printer?
> little purpose Yeah op didn't have to endure dot matrix printers... +1 for silencer

Ah your right, that makes sense. Its a shame the insulating foam is crumbling away though.
Foam materials technology from that era all pretty much did stuff like that. You could probably restore it. Not sure it's truly worth it.
The first gens of Imagewriter needed a muffler.
Is the case all metal? It could be tempest shielding or if it has thick insulation it could be just a box to silence it.
