The HP 7470 was a small low-cost desktop pen plotter introduced by Hewlett-Packard's San Diego division in 1982. It was the first small-format plot that moved the paper, rather than the pens. It used a revolutionary "grit wheel" design which moved the paper held in place by a wheel with embedded grit and a pinch roller.
