The Atari 825 was produced from 1980 until 1982, and was a re-badged Centronics 737 parallel port printer. As such, it did not directly connect to the Atari serial bus, but required a separate Atari 850 interface. Atari 825

Unlike the Atari 820 and 822 printers, the 825 had a carriage that could print 80 characters wide at 10 characters per inch, and supported several different fonts, including proportional text output.

The printer could also support reverse line feeds, and could thus be coaxed into producing multiple column output from programs such as Text Wizard and AtariWriter.
