1. A liquid ejecting apparatus configured to execute a printing operation to eject liquid from a nozzle toward a medium, wherein
the liquid ejecting apparatus is configured to transition to:
a first mode in which less electric power is consumed per unit period than in the printing operation; and
a second mode in which less electric power is consumed per unit period than in the first mode,
the second mode is started at an end of a predetermined period of time following completion of the printing operation,
the first mode is started after the printing operation is completed and before the second mode is started, and
a period of time taken for the liquid ejecting apparatus to return to the printing operation from termination of the first mode is shorter than a period of time taken for the liquid ejecting apparatus to return to the printing operation from termination of the second mode,
wherein the liquid ejecting apparatus comprises:
a driving element configured to be driven to eject the liquid from the nozzle;
one or plural circuits including a driving signal generation circuit that generates a driving signal to drive the driving element; and
a first circuit different from the one or plural circuits, wherein
in the first mode, operation of the one or plural circuits is stopped, and
in the second mode, the operation of the one or plural circuits and operation of the first circuit are stopped.
