A correction unit executes a correcting function for measuring at least one of position and density of a test image in response to a correction instruction and correcting an operation setting of a printing unit based on the measurement result. Print data includes correction requiring data that is required to execute the correcting function by the correction unit before an image corresponding to the correction requiring data is printed. A determining unit is configured to determine whether or not at least one of two conditions is satisfied. One condition is such that a ratio of a second numerical value represented by the correction requiring data to a first numerical value represented by the print data is less than a first reference value. Another condition is such that the second numerical value is less than a second reference value. When the determining unit determines that the at least one of two conditions is satisfied, the control unit bypasses the measurement by the correction unit even if a receiving unit receives the correction instruction.
