Draft or letter quality? This old dot-matrix printer churns out more than carefully aligned pages of text. It plays Bach's Toccata and Fugue in D minor, a piece originally written for the (slightly grander) pipe organ.
The use of outdated electronics to play Bach is not an entirely new phenomenon, however. Predecessors include pieces on 8-bit Commodore 64 computers and musical floppy discs. We're still awaiting a St. Matthew Passion on an Atari with joystick soloists. (YouTube video via CNet.)
