Claim:
A printing device comprising: a plurality of data transfer control units associated with different individual colors, each of which stores image data of an individual color transferred from an upper level device in a storage unit, wherein the image data transferred from the upper level device includes raster image data rasterized by a raster image processor included in the upper level device; a plurality of output control units associated with the different individual colors which are provided correspondingly to the data transfer control units and each of which controls printing of the image data of a respective individual color stored by a specified one of the data transfer control units; and a print control unit that, when abnormality has occurred in any of the data transfer control units associated with the different individual colors, transmits a transfer instruction on the image data of the individual color that is to be transferred originally by the data transfer control unit associated with the individual color in which the abnormality has occurred, to an alternate data transfer control unit associated with a different individual color among the data transfer control units in which no abnormality has occurred, and instructs an output control unit corresponding to the data transfer control unit associated with the individual color in which the abnormality has occurred to print the image data of the individual color that is stored by the alternate data transfer control unit associated with the different individual color.
