Abstract:
1. A print control apparatus that receives compressed data obtained by compressing data to be printed, and generates data for print output by decompressing the compressed data, the print control apparatus comprising: a storage unit that stores the compressed data transmitted from an external source; a reading unit that reads the compressed data from the storage unit on a unit data by unit data basis, the unit data being a predetermined block; a decompressing unit that performs a decompression process on the compressed data read by the reading unit; and a checking unit that checks whether a post-decompression data size of each unit data obtained by the decompression process performed by the decompressing unit is correct, wherein each unit data in the compressed data includes break data as first data and includes, as data following the break data, density data, the number of which is according to a data size in a compressed state, the break data including information on the data size in the compressed state and information on the post-decompression data size, the checking unit determines whether the post-decompression data size of each unit data is correct, based on information on the post-decompression data size included in corresponding break data, and during a period in which the decompressing unit performs the decompression process on certain unit data and during a period in which the checking unit checks the certain unit data, the reading unit can read compressed data for next unit data from the storage unit.
