Thought of them- They are listed as a "Thermal Inkjet Printer", which I 
beleive works by the heating of an element (semiconductor?) in the jet,
which causes a bubble to form, forcing ink out the jet. I beleive this
heating action may damage the fluid we wish to spray. Still haven't found
any _current_ pizo-jet sources...
