Abstract: In a recording system in which a DSC and PD printer are directly connected via a communication interface, and image data is transmitted from the DSC to the PD printer and recorded, it is determined whether predetermined status information is received from the PD printer within a predetermined time period after the DSC issues a predetermined command to the PD printer. If it is determined that the predetermined status information is not received, the status is determined to be one estimated from a normal process, and a process continues. To confirm the status of the PD printer, the DSC requests status information of the PD printer, and acquires the status of the PD printer on the basis of the status information sent back in response to the request.

Abstract: In this invention, to enable printing of an image that has undergone an image process or print process complying with the desire of a user on an image supply device side, real object handles and virtual object handles are set to, of images to be supplied to the printing device, images that require a predetermined image process and remaining images, respectively. A print job including the object handle of a print target image is issued in accordance with a print instruction. If the handle of an image requested by the printing device in response to the issued print job is a virtual object handle, the predetermined image process is executed for image data corresponding to the handle, and the processed image data is supplied to the printing device.

Abstract: In a case where a digital camera cannot understand or recognize a request received from a printer, the camera ignores the received request and discards the received request, and transmits a command that does not include any user instruction or print operation to the printer in place of the correct response to the request. In such case, the printer receives the command as the response to the request, and recognizes that the request transmitted by the printer cannot be accepted by the camera.

Abstract: When a DSC and PD printer are directly connected via a communication interface, and a recording process in the PD printer is interrupted while transmitting image from the DSC to the PD printer and recording the image data, the DSC designates the restart of recording process and it is determined whether the type of PD printer is a type capable of restarting recording process. In a case where the type is determined to be the type capable of restarting recording process and a DPOF file is being printed, the DPOF file is resent to designate print from a page next to the printed page. In a mode in which image data are sequentially transmitted to the printer and printed, print process of image data subsequent to the printed image data is designated.

Abstract: A testing apparatus which, when resuming a test after interruption, makes it possible to determine whether or not an apparatus to be tested is the one for which the test has been interrupted. A controller acquires identification information for identifying the apparatus to be tested. The controller carries out a test comprised of a plurality of testing items to be executed on the apparatus to be tested. When the test is interrupted, a recording section is operable to record resuming information for carrying out the test on unexecuted testing items among the plurality of testing items, and the acquired identification information.

Abstract: A digital camera has a storage medium which stores imagedata and a DPOF associated with a print process of the image data, acquires information associated with the function of a printer upon connection of that printer, sets a CDPS job command associated with the print process of the image data on the basis of the acquired information associated with the functions, sets a print condition for the printer on the basis of the DPOF and CDPS command, and sends a print instruction. The printer acquires image data stored in the storage medium in accordance with the designated print condition and prints the image data.

Abstract: According to a print system, a printer supplies function information of the printer to a DSC based on a communication link between the DSC and the printer, and the DSC establishes a UI based on the supplied function information to display it on the DSC. The DSC converts image data of an image file according to print conditions set up based on the UI and the function information of the printer and transmits the converted image file to the printer.

Abstract: When the function of a printer has been changed, the printer notifies a DSC of a change in printer function using a capabilityChanged tag. If the DSC does not return any inquiry about the capabilityChanged tag, the printer determines that the DSC has no function that supports the capabilityChanged tag. The printer executes disconnection and re-connection of USB to execute a communication procedure with the DSC from the beginning, thereby notifying the DSC of the latest capability information in the printer.

Abstract: After applications installed in a DSC and PD printer establish a communication procedure, the DSC issues a request to the PD printer. A time required for data transfer involved in the request is predicted. An elapse time until a response is received from the PD printer in response to the request is estimated on the basis of the predicted time. If no response is returned from the PD printer within the estimated elapse time, the request is disabled.

Abstract: A print command has a hierarchical structure including a vendor common code, and a vendor unique code, an index print mode or date print mode is designated using the common code, and a detailed print format of each image or the number of index images per sheet in the index print mode can be designated using the unique code.

Abstract: According to an aspect of the present invention, when a printer which is directly connected to a digital camera via a communication interface and records image data transmitted from the digital camera receives a recording request from the camera, the printer acquires an image data amount to be supplied from the digital camera, and determines whether to be able to receive the whole image data at once and process the image data. In a case where it is determined that the image data is not able to be processed, the printer requests segmented data of the image data stored in the digital camera. The printer receives the segmented data a plurality of number of times, and prints the whole image data.

Abstract: An image output system connects at least three devices as a server and client via a versatile interface, and outputs an image by transferring data among these devices. In this system, a DSC serves as a client of a storage device and printer. The DSC transmits a list request of image files stored in the storage device to the storage device, which transmits list data of the image files to the DSC together with an identification ID of the list request in response to the list request. When the DSC sends a print instruction to the printer, the printer transmits a request of image data of an image designated by the print instruction to the storage device together with the identification ID, acquires image data from the storage device as the client, and outputs an image.
