Abstract
A liquid supply apparatus includes a liquid storage container including a memory, a liquid feeding mechanism that feeds out liquid to the print head, and a second controller. A first liquid consumption amount is a consumption amount of liquid consumed in a non-printing operation in which liquid is not discharged from the print head to a recording medium, and a second liquid consumption amount is a consumption amount of liquid consumed in a printing operation in which liquid is discharged from the print head to the recording medium. The second controller calculates the second liquid consumption amount based on a liquid feeding amount of liquid fed out from the liquid feeding mechanism in a printing operation, stores the second liquid consumption amount in the memory, receives the first liquid consumption amount from the first controller, and stores the first liquid consumption amount in the memory.
