Abstract
A controller includes a plurality of control circuits configured to be connected to respective ones of a plurality of head units. Each head unit has a nozzle. The plurality of control circuits includes a first control circuit, a second control circuit connected to the first control circuit in series to perform communication, and a third control circuit connected to the second control circuit in series to perform communication. The first control circuit is configured to transmit first data to the second control circuit. The first data is data for controlling at least one of the plurality of head units. The second control circuit is configured to transmit second data to the third control circuit. The second data is data for controlling at least one of the plurality of head units. A data amount of the second data is smaller than a data amount of the first data.
