Abstract
In order to provide an ink jet printer achieving a constant printing quality regardless of the type of sheet to be used, a switch for selecting the type of sheet for the printer is provided. The type of sheet to be used is determined according to the state of the switch. Based on the result of the determination, the diameter of an ink drop emitted from a nozzle is changed. Since the degree of spreading of ink as well as the degree of absorption of ink differ depending on the type of sheet, the image quality after printing can be made constant regardless of the type of sheet by changing the diameter of ink drops.
