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.
