  Wiki's also a pretty good shot, but probably one of the first links 
from Google anyway.  Problem is both are heavily weighted to current 
technology, pretty sure someone did use current through the ink to make 
the bubble early on, likely Cannon since they were well before the 
others with wide market inkjets like late 70's or early 80's.
