There's a short video of the printer printing towards the bottom of the article. You can see the printing in that.
On the other hand, a Snoopy calendar printed on that would be cool :)
Wonder if it's as incredibly noisy as a regular dot-matrix printer. In the video it sounds almost pleasant.
It's loud enough that NASA put acoustic down in the locker for the printer. But it's not screeching like dot matrix.
Yeah they are loud. The printers used in data centers had soundproof (well, sound-reducing) enclosures. If you raised the lid while one was printing, it was very loud.
I worked with line printers for many years and they were as noisy as hell. Pretty fast though.
