Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 decompressin…
