A braille printer.
We've tested that it powers on but not been able to test the printing as we don't have the right paper format.
The buttons are marked with braille and an electronic voice reads out the various functions/menu items when you press the buttons.
It comes with a power cable, serial cable, and an adaptor to be able to plug the serial cable into a USB port. We don't have any drivers/software for it but hopefully that's easy to find online? Or they might autoload when plugged in, depends on your operating system I guess.
