Claim 11:
12. A method for controlling an inkjet recording device, the inkjet recording device including an inkjet discharge head including a nozzle through which ink is discharged, a pressure chamber that communicates to the nozzle, and a pressure generator that generates a pressure change in ink in the pressure chamber according to application of a drive signal to cause ink to be discharged from the nozzle; a driver that is disposed outside the ink discharge head and that is provided with a drive circuit that outputs the drive signal; and a wire that electrically connects the driver with the ink discharge head and through which the drive signal output from the drive circuit and applied to the pressure generator, wherein the driver includes a resistance element provided in a transmission path of the drive signal between the drive circuit and the wire, wherein the nozzle includes multiple nozzles, wherein the pressure chamber includes multiple pressure chambers corresponding to the multiple nozzles, and wherein the pressure generator includes multiple pressure generators corresponding to the nozzles,
wherein at each time of application of the drive signal, a resistance value of the resistance element is adjusted such that a magnitude of the resistance value of the resistance element corresponds to a length of the wire and to a number of nozzles through which ink is discharged at a same timing among nozzles,
wherein the resistance element is provided in a state in which the resistance value is changeable,
wherein the inkjet recording device further comprises:
a resistance value controller that changes the resistance value of the resistance element; and
a temperature detector that detects a temperature corresponding to the temperature in the ink discharge head, and

wherein the resistance value controller adjusts the resistance value of the resistance element based on the temperature detected by the temperature detector.
