Abstract:
An image forming system displays warning information representing a state of no printing sheet detected in a first sheet holding unit, and displays information representing a normal state of no sheet printing sheet detected in the second sheet holding unit. In a case where a transition occurs from a state where at least one printing sheet is in the second sheet holding unit to a state where there are no sheets in the second sheet holding unit while the image forming apparatus performs printing using the printing sheets held in the second sheet holding unit, displaying warning information representing a state of no printing sheet in the second sheet holding unit and changes to information representing a normal state in the second sheet holding unit if a predetermined period has passed.
