Epson, HP, and Cannon are all different tech slightly, I think you're
thinking Cannon Bubblejet not HP type. Been a long time since I've
refreshed on the Cannon tech but it's something more like what you
described. HP is just a resistor heater to vaporize and push out some
ink, Epson is piezo-mechanical.. Cannon was first with a reliable one
long before the others, but HP and Epson pretty much superceded them
after getting it right. HP's heads are reasonably cheap and easy to
produce, that's how they're throw away on the cart. Piezo-mechanical
are much more expensive and why Epson's are on the printer. Only reason
their printers are even cheap is they make the money on the inks.. Even
Epson high end inks aren't so terrible though if you buy the 500ml for
the large plotters, just an $800 outlay for all colors and a hassle to
split it up. Their yellows are superior, there's a website on doing
this and the difference is very notable, just not worth it for most
people. Their seperate cart price for 500 ml ends up being $2K or so,
not bad for colored water.. :)
