You never know, you never know...

Actually i have found a document describing printhead design specifically
mentioning the one i looked at (black from HP 550C) and it does seem there
are resistors allright.

I dunno with which 'scope i looked back then, but i remember just behind
each nozzle there were two structures that looked like electrodes. Must
have had some other purpose. I don't have the stuff any more so can't
investigate.
