Abstract
A printing apparatus capable of easily setting driving conditions in consideration of conditions on the printing apparatus main body side as well at an arbitrary point of time is disclosed. The printing apparatus including a printhead having a plurality of print elements and a head driver for generating a pulse-like driving signal supplied to the printhead. The apparatus sets driving conditions for a printhead with test patterns obtained by simultaneously driving a predetermined number of print elements of the plurality of print elements are printed on the printing medium while the pulse width of the driving signal is decreased stepwise from a predetermined value. Then, the boundary value of a pulse width with which a print element is not properly driven is obtained from the test patterns, and the pulse width of a driving signal generated by the head driver is controlled on the basis of the boundary value.
