Some of the Teletype guys like to say "WE had the first ink jet printer"
which may be true but it was totally unrelated to the later ink jet 
printers that are still on the market.  The Teletype Inktronic (what a
name!) worked by electrostatically deflecting charged droplets of ink
in two dimensions.  It had 40 nozzles and sets of deflecting plates
to print 80 columns on 8 1/2 inch wide paper.  A brilliant concept,
a fiasco as a product.  The high voltages on the deflecting electrodes
attracted paper dust which distorted the printing.  Attempting to clean
the electrodes usually resulted in bending them.  Hence the printing
was legible at first but deteriorated as time went on.
