Abstract
A printing apparatus, having a plurality of heads, a plurality of head controlling circuits, a master transmitter, and a determining unit, is provided. The head controlling circuits are connected to the heads in one-to-one correspondence and are connected with one another serially. Each head controlling circuit controls a corresponding one of the heads to record a part of the image based on master data. The master transmitter transmits the master data to a most upstream one of the head controlling circuits. The head controlling circuits are configured to pass the master data received by the most upstream one of the head controlling circuits serially downstream onto a most downstream one of the head controlling circuits, and generate differential data indicating a difference between the master data and read data generated by reading an image. The determining unit determines whether the image contains a defect based on the differential data.
