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: 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.

Abstract: There is provided a printing apparatus that can prevent a user from forgetting to set print settings and that can markedly reduce the number of unnecessary prints caused by unsuitable print settings, for example, in a case in which print data such as image data is sent from an image-supplying apparatus to the printing apparatus and in which the printing apparatus prints the print data. The printing apparatus, which receives print data from an image-supplying apparatus and prints the print data, need not start printing image data immediately after the image data is received. An input of print settings is accepted in the printing apparatus, and the image data is printed using the printing settings that have been input.

Abstract: A photo-direct printer apparatus which prints an image on the basis of image data from a digital camera, memory card, or PC serving as an image data source receives a control command from the image data source, interprets the control command, and receives image data from the image data source on the basis of the command. The printer apparatus decodes and processes the received image data, and generates and prints print data and print an image based on the print data.

Abstract: Print settings changed in a direct printing-capable image forming apparatus are treated as either temporary changes or permanent changes depending on the state of the image forming apparatus when the print settings are changed. Specifically, print settings changed when the image forming apparatus is in a direct printing-executable state are treated as temporary, whereas print settings changed when the image forming apparatus is in a direct printing-inexecutable state are treated as permanent. Usability regarding print settings is improved.

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: An image printing apparatus and its control method for printing an image based on image data from an image data source. In a case where a correction condition is set for the image data, if the image data is a new format file image data including predetermined information, correction processing is performed in accordance with the set correction condition. If the image data is not a new format file image data, the correction processing in accordance with the correction condition is not performed.

Abstract: A print-direct printer for receiving and printing JPEG data from a DSC divides the area of a memory into a plurality of blocks, stores the received JPEG data in the memory on a block-by-block basis and decompresses the compressed JPEG data that has been stored in the memory, thereby expanding the JPEG data into image data. If it is determined that JPEG data to be expanded next has not been stored in the memory, then the DSC is requested for JPEG data corresponding to at least one block, in an amount that is less than the maximum amount of data transferable from the DSC, in addition to the JPEG data to be expanded.

Abstract: An image printing apparatus and its control method for printing an image based on image data from an image data source. In a case where a correction condition is set for the image data, if the image data is a new format file image data including predetermined information, correction processing is performed in accordance with the set correction condition. If the image data is not a new format file image data, the correction processing in accordance with the correction condition is not performed.

Abstract: A printing apparatus according to a preferred embodiment of this invention receives, from an image supply device, a first script “DDISCVRY.DPS” that describes the print function of the image supply device. If the first script describes support for printing by XHTML, the printing apparatus determines whether printing corresponding to the description is possible. The printing apparatus transmits a second script “HDISCVRY.DPS” that describes a print function executable by the printer to the image supply device in accordance with the determination result.

Abstract: There is provided a print system for transmitting and receiving a data object by a PTP between a camera-equipped mobile phone (CP) and a PD printer and printing an image by the PD printer according to image data supplied from the CP. First information indicating presence/absence of the direct print function capable of printing by transmitting image data from the CP directly to the PD printer and second information indicating presence/absence of the cooperated processing function with the CP and the PD printer are embedded in a data object which is transmitted and received. When it is judged that the received object contains the first and the second information, the CP and the printer are set to the direct print function and the cooperated processing function mode.

Abstract: A DSC 1 (3012) and a DSC 2 (2012) are connected with each other via an interface different from that of a photo-direct printer 1000. When the job controller 1023 receives a job from the DSC 1 or DSC 2, it stores printing information, which is information on the job, and information on a source of the job, in a queuing buffer 1024 associated with each other. The job controller 1023 can accept printing information from the DSC 1 or the DSC 2 in parallel with a printing process. The job controller 1023 can also perform a canceling process of a job queued by using information on a source.

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.
