This is an area that causes a lot of people to wonder, because it is often said that in this category of printer all of them produce excellent results. From your observation, exactly what are the real advantages of the Piezo technology?

Not having to heat the ink for one, or having to replace the heads, or the tiny droplets that seem to get smaller and smaller with each new generation.

Hi I'll happily put my hand up and say I've been out of printer development for 5 years now, so I wonder what it is about piezo that now makes it the only tech capable of small drops? Canon's FINE heads had no problem with 1 picolitre. Have Epson gone suddenly a long way under a picolitre?

Micro Piezo technology allows for precisely controlled ink droplets of up to five different sizes to be ejected from the print head, resulting in sharper, grain-free photo prints with smoother tonal transitions.

That advantage from the article sounds like marketing fluff. That's something they have all been doing for donkeys years.
