Abstract: A device identification information managing system is provided. A network printer generates an extension device identifier depending upon dynamic information and a subject-of-registration-device identifier including a basic device identifier of the storage device and a generated extension device identifier, to send the generated subject-of-registration-device identifier to a printer managing server and notify the user. The printer managing server, when receiving a subject-of-registration-device identifier, tentatively registers the received subject-of-registration device identifier to the storage device. When a collating device identifier is received, the received collating device identifier is collated with the subject-of-registration-device identifier of the storage device. Depending upon the collation result, the subject-of-registration-device identifier is registered to the storage device.

Further, when another projector display data is received during projection, the projector additionally stores the page data included in the other received projector display data in the stack area by the stack system.

Abstract: 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.
