Abstract
In a printing apparatus including a reception buffer which stores setting data and printing data of printing element arrays transmitted from a connected host device, and a printing buffer which stores the printing data of the printing element arrays in association with printing positions in a scanning direction, the printing data are controlled to be stored in the printing buffer by adjusting the storage positions of the printing data of the printing element arrays on the basis of registration information which is contained in the setting data and corresponds to the relative distance between the printing element arrays in the scanning direction. Read address information for reading out the printing data stored in the printing buffer is controlled for each printing element array. Printing is performed by driving each printing element array in accordance with the printing data read out on the basis of the read address information. The printing apparatus executes a registration adjustment process associated with the relative distance between the printing element arrays that has conventionally been done in a host device, simplifying a printing data generation process by the host device.
