Print control apparatus, inkjet printing apparatus, print control method, and recording medium with data compression/decompression
Abstract:
Compressed data transmitted to a print control apparatus includes break data having information on a compressed size and a decompressed size for each page. When the compressed data is transferred to a decompressing unit, the break data is converted to NOP data. Information on the decompressed size included in each break data is provided to a checking unit. During a period in which a decompression process is performed, a decompression flag is turned on. The checking unit obtains the actual decompressed size by counting a period in which the decompression flag is turned on, to check whether the decompression process has been normally performed. During a period in which the decompressing unit and the checking unit perform processes for a certain page, a reading unit reads compressed data for the next page.
