The HP 7470 was a small low-cost desktop pen plotter introduced by Hewlett-Packard's San Diego division in 1982. [1] It was the first small-format plot that moved the paper, rather than the pens. [2] It used a revolutionary "grit wheel" design which moved the paper held in place by a wheel with embedded grit and a pinch roller.

The 7470A was the world's first small format paper-moving plotter. Previous plotters held the paper still while a mechanical arm held a pen to draw a 2-dimensional image. The advantages of the paper-moving technology were: lower costs due to fewer mechanical parts, higher speed due to the much lower inertia of the moving parts, and smaller size.

Like the 7470, it used paper-moving technology. It also had a 6-pen carousel and could plot on both A/A4 and B/A3 size paper. The 7475A had a 6-pen carousel instead of an 8-pen carousel so it wouldn't overlap with the market for the yet-to-be-released . In 1984, the 7475 was the most profitable single product within HP.

2019年12月23日 · I've been wanting to check out the HP-7470A Plotter simulator in the pyILPer PIL-Box client, but never having had one, I don't have any programs to throw at it. I took a peek at the "Interfacing and Programming Manual" (available at the HP Computer Museum) and see that getting into the graphics language is no small undertaking.
