Abstract
Data for C, M, Y and K color nozzle arrays are stored in the same memory area in an image buffer 31'. The data groups, which are to be respectively transmitted to the C, M, Y and K color nozzle arrays at a specific print timing, are stored at continuous addresses in the image buffer 31', as is shown by the shaded portion. In a transfer process, a plurality of bytes for the C, M, Y and K color nozzle arrays, which are at continuous addresses 1 to 20, are read as a data set from the image buffer 31', and at the same time are transmitted to the print head.
