Ed, 

thanks for adding that about the one-ply NCR impact paper.

The Extel  printers used by the wire services were bought with either the 
impact paper or  the ribbon printing, although I'd guess the ribbon printing 
machine would work  with the impact paper.  

One point on the ribbon printing Extels,  the coarser TTY ribbons didn't 
work too well with the Extels.  The Extel  printer head used 7 needles (maybe 
more?) and required the finer thread count  of the nylon ribbons so the 
needles would not snag on the ribbons.

A lot of the Extel  printers were ribbonless and used a special impact
sensitive paper from  3M that must have been expensive.  Other Extel
printers were fitted  with ribbons and could use ordinary paper.  So
far as I know you  can't get the impact sensitive paper anymore, so
Extel printers without  the ribbon mechanism are  dead.
