Not necessarily.  You are describing an implementation, not a process.  I
still contend, and what sources I have checked, concur that the process is
called halftonging, and that dithering is a technique that can be used in AN
implementation of halftoning.

I believe you are, again, referring to an implementation of the halftone
process, namely varying the drop size, as opposed to building the halftone
cell from a number of dots.

I'd like to see references that support you, if you have any.  Adobe
supports my contention in their technical guide on halftoning:

2.html

Also, why would inkjet be any different than laser?  They both print in dots
at a particular resolution.
