Patent ID: 8368947

Claim:
A print data creation apparatus for creating print data in band units, the print data creation apparatus comprising: a processing unit; and memory storing computer-readable instructions that, when executed by the processing unit, cause the print data creation apparatus to perform operations comprising: sequentially obtaining, from an external apparatus, each of a plurality of partial compressed data included in particular compressed data which is compressed data of one or more image objects; sequentially decompressing compressed data so as to create each of a plurality of partial decompressed data; deleting, each time one partial decompressed data is created from one partial compressed data, the one partial compressed data determining, each time the one partial decompressed data is created, forte which band the one partial decompressed data is necessary; deleting, each time a band has been determined for one partial decompressed data, the one partial decompressed data; storing, each time a band has been determined for one partial decompressed data, an association of the band and a data range of one partial compressed data that is original of the one partial decompressed data in a specific memory area; specifying from the specific memory area, after the association for each of the plurality of partial decompressed data has been stored in the specific memory area, a target data range associated with a target band of which print data is to be created; re-obtaining, from the external apparatus, target compressed data of the particular compressed data, target compressed data having the specified target data range; and decompressing the target compressed data so as to create target decompressed data, and converting the target decompressed data so as to create print data of the target band.
