The apparatus includes a nozzle portion having a length corresponding to a width of a printing medium, a dot counting unit to group head nozzles by position and to count a discharged dot count per line for each group, a control unit to determine whether the group has been used to print using the discharged dot count per line, a counter to count a number of times that the group is used to print based on the determination result, and a memory to store a sum of the counted numbers of times, in which the control unit controls the counter to count the number of times that the group is used to print with respect to each line of image data when the image data is created by a head chip, and a sum of the counted number of times is stored in the memory.
