A print data creation apparatus for creating print data in band units, the print data creation apparatus comprising: an obtaining device (18, 24) that is configured to obtain compressed data (122, 124, 126, 128, 130) of one or more image objects; a decompressed data creation device that is configured to create decompressed data by decompressing the compressed data (122, 124, 126, 128, 130) of the one or more image objects in partial units; characterized by a band determination device that is configured to determine, for each decompressed data created by the decompressed data creation device, to which band (112, 114, 116) the decompressed data is necessary; a deletion device that is configured to delete each decompressed data for which a band (112, 114, 116) has been determined by the band determination device without utilizing said each decompressed data for printing; a data range storage device that is configured to store, based on information determined by the band determination device, for each band (112, 114, 116), an association of the band (112, 114, 116) and a data range of the compressed data (122, 124, 126, 128, 130) that is necessary for creating print data corresponding to the band (112, 114, 116); a data range specifying device that is configured to specify, based on information stored in the data range storage device, a data range of compressed data (122, 124, 126, 128, 130) associated with a band (112, 114, 116) of which print data is to be created; and a print data creation device that is configured to create decompressed data by decompressing compressed data (122, 124, 126, 128, 130) within the data range specified by the data range specifying device and to convert the decompressed data into print data. an obtaining device (18, 24) that is configured to obtain compressed data (122, 124, 126, 128, 130) of one or more image objects; a decompressed data creation device that is configured to create decompressed data by decompressing the compressed data (122, 124, 126, 128, 130) of the one or more image objects in partial units; characterized by a band determination device that is configured to determine, for each decompressed data created by the decompressed data creation device, to which band (112, 114, 116) the decompressed data is necessary; a deletion device that is configured to delete each decompressed data for which a band (112, 114, 116) has been determined by the band determination device without utilizing said each decompressed data for printing; a data range storage device that is configured to store, based on information determined by the band determination device, for each band (112, 114, 116), an association of the band (112, 114, 116) and a data range of the compressed data (122, 124, 126, 128, 130) that is necessary for creating print data corresponding to the band (112, 114, 116); a data range specifying device that is configured to specify, based on information stored in the data range storage device, a data range of compressed data (122, 124, 126, 128, 130) associated with a band (112, 114, 116) of which print data is to be created; and a print data creation device that is configured to create decompressed data by decompressing compressed data (122, 124, 126, 128, 130) within the data range specified by the data range specifying device and to convert the decompressed data into print data.
