An ink jet printer and control method therefor efficiently eliminates temporary ink eject defects during print interruptions. A time interval, i.e., the time lapse between a previous ink ejecting operation and a present ink ejecting operation, is evaluated before printing. If the time interval is less than a first time reference value (t1), an ink purging operation is not performed or is performed only a first minimum number of times. If the time interval is between first and second time reference values (t1</=TI<t2), ink purging is executed a second number of times. If the time interval is greater than or equal to the second time reference value (t2</=TI), ink purging is executed a third number of times that is less than the specified second number of times.
