Abstract
An image processing apparatus which inputs PDL described print data from a host computer, interprets the print data to develop the data into bitmap image data, and transfers the bitmap image data to a serial printer. Upon transferring the bitmap image data, the apparatus determines whether or not image data corresponding to one scanning by a print head of the printer, i.e., one band, includes image data having a value '1' according to a dot to be printed. If the image data includes no '1' data, i.e., all data values are '0', the apparatus controls the printer to omit scanning by the print head at the band corresponding to the image data including no '1' data and feed the recording sheet for the band.
