Abstract
A printer which enables flexible printing control to be performed in conformity with the capacity of a memory installed to satisfy the requirements of a user. In this printer, it is first determined whether the additional memory has been installed or not. Then, the printer further examines the total available capacity of the basic memory and additional memory based upon results of the determination, compares the total capacity with an amount of data necessary to perform printing by a single scan using all ink discharge nozzles of a printhead, decides, based upon the results of the comparison, the capacity of a buffer memory for temporarily storing printing data to be transferred to the printhead, and decides to change resolution in the scanning direction or whether to perform printing by multiscan printing using the buffer memory having the capacity decided or perform printing in which printing using all ink discharge nozzles of the printhead is completed by a single scan of the printhead.
