摘要
A printing apparatus having a printhead for printing by discharging liquid on a printing medium performs a toggle preliminary discharge operation of alternately performing discharge from main nozzles and dummy nozzles in order to establish a good discharge state of the liquid from the main nozzles. The main nozzles and the dummy nozzles communicate with liquid chambers, which in turn communicate with a common liquid chamber. A control circuit for the printhead and a control method are also provided.
