8. A method, comprising:
-
emitting electromagnetic radiation (EMR) indicative of an image to print, wherein the emitted EMR varies based on a direction of emission; detecting at a location, using an unmanned aerial vehicle, the emitted EMR; and ejecting, based on the location of detection and using the unmanned aerial vehicle, a substance corresponding to the EMR detected. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A system, comprising:
-
a electromagnetic radiation (EMR) emitter to emit EMR indicative of a first substance to print at a first location towards the first location and to emit EMR indicative of a second substance to print at a second location towards the second location, the EMR indicative of the first substance and the EMR indicative of a second substance corresponding to an image to be printed; and a modulation engine to cause the EMR emitter to emit the EMR with a modulation distinguishable from background EMR. - View Dependent Claims (16, 17, 18, 19, 20)
