摘要:
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.
摘要:
When a print command that designates a layout recording function by its upper layer, and designates a frame print function by its lower layer is transmitted from a camera to a printer, the printer determines a layout print function that prints a plurality of images on a single sheet, based on the upper layer. In a case where the printer can determine the lower layer of the command, the printer acquires details of a layout. In a case where the printer cannot determine the lower layer of the command, the printer determines a normal frame print function. The printer prints a normal layout image or special frame image in accordance with the determined layout of images.

摘要:
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.
摘要:
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.

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