ABSTRACT:
To provide a printing system and a printing apparatus which can ensure high-speed, normal printing with small memory requirements even when lots of print commands are sent to a printer. The printing apparatus includes a print mode determination unit which judges whether intermediate-language data can fit in a page memory when print command data is converted in normal print mode and selects the normal print mode if the data can fit in, but selects compressed print mode if the data cannot fit in. Furthermore, the print mode determination unit includes a data reprocessing unit which, when the compressed print mode is selected, reduces any compressible part of intermediate-language data which corresponds to fine-gradation image data in normal print mode using a compression/decompression process, output gradation conversion process, clipping process, or reversible compression process whichever is applicable before storing it again in the page memory.
