Digital BW, The Print

Actually, bubble jet heads are in essence a network of mini-resistors,
an electric pulse will heat the ink up to a bubble and then sudden cooling
will make it burst (roughly, this is what is taking place, in layman's terms).
I own both Epson and Canon printers (the latter for color only) and I think
that if you move into "dye" ink territory, it is wide open as far as which
printhead technology has the edge. It would of course be counterproductive
to launch a discussion as to which tool is the best overall, depending on the
task and the results you expect some are more apt than others.

  I can't speak to Iris, but Epson piezo-electric heads work much differently
  than other printers.  When I went to the Epson inkjet repair school it was
  explained pretty well, though technologies change.

  Canon Bubblejet (they dropped the name so I don't know if they dropped the
  system) rather than squirt the ink, heated an ink bubble that burst and
  layed down.  Actually, you could see the uneven spatter under magnification.
  Basically, it farted on the paper.

  HP was using just a plain old airbrush approach, though more refined.

  This is another reason "universal" refill kits for desktops is bull.

  Each head technology has its own limitations and pluses.

  "Son of EP," small company that it is has managed to kick the big boys
  (Canon and HP) for some time now.
