The present invention provides stable support for the extended arm of the operator of a projectile weapon or camera. The individual dots of the coarse matrix and intermediate matrix are immediately partially cured after each individual step to such an extent that the dots do not run into each other and that further colors can be applied to the already printed dots. Fluid drop ejection and drop formation can vary from fluid to fluid, and require adjustments to waveform parameters of a drive pulse applied to the multiple nozzles.
