    • A printing system is provided suitable for reducing a printing time. A client apparatus acquires document data being edited during an editing operation by an application, creates print data for evaluation based on the acquired document data, selects a compression algorithm suitable for the created print data for evaluation from a compression algorithm registration database, compresses print data in accordance with the selected compression algorithm, and sends the compressed print data to a printer along with a print request. The creation of print data for evaluation and the selection of a compression algorithm start during an editing operation by the application. When the printer receives compressed print data along with a print request, the printer decompresses the received compressed print data and prints based on the decompressed print data.
