What happens when computer printer marries a chainsaw and a player piano? A piece of 1960s computer equipment called a chain printer that printed at alarming speeds, even by today’s standards. Band printers were similar to chain printers except were more like band-saws than chainsaws. Most print chains and print bands had limited punctuation, no accents and no lowercase letters. Chainprinter recreates the effect of this mechanical marvel/nightmare of yesteryear. Want a crisp version with lowercase? Try Linefeed.
