This invention relates to a printing system, printing method, printing apparatus, and driver capable of printing at high-speed even when a transfer data amount increases. According to the system, in a host apparatus, a compression pattern of image data is generated. Image data corresponding to one print scan of a printhead is compressed by using the generated compression pattern. The generated compression pattern and the compressed image data corresponding to one print scan of the printhead are transferred to a printing apparatus. In a printing apparatus that executes multi-pass printing, the transferred compression pattern and the compressed image data are received. The received compression pattern is stored into a memory as a decompression pattern. The received compressed image data is decompressed by using the stored decompression pattern and stored in a print buffer. Multi-pass printing is executed by scanning the printhead by using the image data stored in the print buffer.
