Atari 822 - FujiNetWIFI/fujinet-firmware GitHub Wiki
The Atari 822 is a thermal printer that Atari licensed from Trendcom from 1980 until 1982. It uses special thermal paper, which reacts with heat emitted from the print head to form the dots on the paper. Because of this, it was very silent, compared to dot matrix and daisy wheel printers.
It also plugs into the SIO port, and provides a pass-through connector for daisy chaining other peripherals.
Atari licensed the printer design from Trendcom, and it is most like the Trendcom Model 100.
The Atari 822 was unique of all the Atari printers for its ability to print bitmapped graphics of approximately 280 dots across.
