Abstract:
A print control apparatus comprising:a first memory unit, arranged for storing compressed image data; a conversion circuit, arranged for converting the compressed image data stored in said first memory unit to a converted image data; a second memory unit, arranged for storing the converted image data converted by said conversion circuit, wherein said first memory unit has a capacity determined based on a capacity of said second memory unit and an increase rate in compression associated with the compressed image data; and a control unit arranged to, if a certain band of data comprises one piece of compressed image data, (i) transmit the one piece of compressed image data to said first memory unit without forming a frame buffer for the band so as to store the one piece of compressed image data in said first memory unit, (ii) control said conversion circuit to convert the one piece of compressed image data stored in said first memory unit to a converted image data, (iii) control said second memory unit to store the converted image data converted by said conversion circuit, and (iv) transmit the converted image data stored in said second memory unit directly to a printer engine.
