Not exactly. There are variable drop sizes in many new desktop inkjet
printers. I -think- that for a given DPI setting the droplet size
stays the same, but for higher resolutions it uses smaller droplets
with heavier coverage.
My old Canon BJC 6000 does two sets of nozzle checks, one very light
and thin. I think it's testing at two different droplet sizes.

Yes, the heads are still the same 720dpi print heads, it's the
movement of the paper/head. Fine for photos, not as much use for
lineart such as PCBs.
Note that most Epsons are 720x1440, or 720x2880, and aren't there some
that claim 1440x5760?
