You'll need more than just a logic analyzer. There is a high voltage analog waveform that drives the piezo actuator in each nozzle. The shape of the pulses control how the drops and satellites are formed and ejected from the nozzles. Piezo heads are more difficult to drive than thermal inkjet heads.
