Digital BW, The Print

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.
