What about not being a bubble jet printer? Aren't all HP print
cartridges equipped with a bubble jet print head?

You're confusing BubbleJets (Canon) with InkJets (HP/Epson). The former
use a heating element per pixel, the latter use a piezo element.

But the end result is still a bubble of ink.

No. The piezo heads send droplets, not bubbles.
