The way they captured the actual spray whilst printing was really clever.
The print head is in a fixed location, as is the camera. The paper is moved under the print head. BUT! the clever bit is having the printhead driven by the rotatry encoder attached to the moveable platform
This means that the head is always in focus, and perfectly lit, plus you can experiment with speed trivially.
