Abstract:
1. A printing apparatus which includes a storage section which stores image data therein, image compressing means for compressing image data, image decompressing means for decompressing compressed image data, and a printing engine for performing printing on the basis of image data, the printing apparatus comprising: dividing means for dividing image data into plural pieces of divided image data; compression/non-compression determining means for classifying one or more pieces of the divided image data as compressible image data and classifying one or more other pieces of the divided image data as non-compressible image data; writing means for causing the image compressing means to compress the compressible image data, writing the compressible image data thus compressed into the storage section, and for writing the non-compressible image data into the storage section; and reading means for reading the non-compressible image data and the compressible image data thus compressed from the storage section, transmitting the non-compressible image data thus read to the printing engine, causing the image decompressing means to decompress the compressible image data thus compressed, and transmitting the compressible image data thus decompressed to the printing engine.
