[GreenKeys] Ribbons, Extel

[Jim Haynes]

Some Extel printers use an inked ribbon.  Others use a special paper,
developed by 3M, in which the ink is held in little capsules on the
surface of the paper and pressure breaks them.  I would imagine the wire
services used inked ribbons because of the cost of the ink encapsulated
paper.  I haven't been able to find any of the paper recently.
