The communication control unit 102 controls the communication unit 101.

  The print command analysis unit 104 analyzes the print request (print command) received by the communication unit 101 from the communication unit 201 of the digital camera 2. Based on the designated print setting (output setting), the output setting control unit 105 generates a bitmap image suitable for the image output unit 106 from the image data. The image output unit 106 prints the generated bitmap image on the paper supplied from the paper supply unit 107.

  When there is a request for print capability information, which will be described later, via the communication unit 201 of the digital camera 2 and the communication unit 101 of the multifunction device 1, the divided drawing control unit 103 determines the size of the paper that can be printed on one sheet in its own machine. Of these, the digital camera 2 is notified of printing capability information with a paper size larger than the maximum paper size (maximum paper size) as a printable paper size.

  When the split drawing control unit 103 receives a print request with a paper size larger than the maximum paper size as the designated paper size via the communication unit 201 of the digital camera 2 and the communication unit 101 of the multifunction device 1, one sheet of paper The output setting control unit 105, the image output unit 106, and the like so as to form a paper size larger than the maximum paper size on a plurality of sheets combined with the printable paper sizes, By controlling the paper feed unit 107, a paper size larger than the maximum paper size can be printed as the designated paper size.

  The direct print system according to the present invention is configured such that an enlarged continuous shooting function can be used when the digital camera 2 prints an image on the multifunction device 1 by the direct print method. The digital camera 2 is connected to the multifunction device 1 via the USB cable 3. The digital camera 2 makes a print request in the direct print format in order to print the captured image (digital image) with the multifunction device 1. Hereinafter, a job related to a print request is referred to as a print job.

(Direct print sequence)
FIG. 5 is a sequence diagram illustrating an example of a general processing procedure performed by the multifunction apparatus and the digital camera during direct printing. When the multifunction device 1 and the digital camera 2 are connected, the multifunction device 1 and the digital camera 2 exchange print services with each other in steps S501 and S502.

  Thereafter, in step S503, the digital camera 2 requests printing capability information from the multifunction device 1. In step S504, the multifunction device 1 notifies the digital camera 2 of printing capability information. The print capability information includes, for example, print quality, paper size, whether or not index printing (index printing) is possible, and information on the layout of an image drawn on one page. The digital camera 2 configures a direct print user interface (UI) screen based on the notified print capability information.

  In step S505, the user operates the user interface screen of the digital camera 2, selects one or more captured images to be output, sets output conditions, and instructs the output.

  In step S506, the digital camera 2 transmits job information as shown in FIG. FIG. 6 is a configuration diagram of an example of job information transmitted from the digital camera to the multifunction peripheral. The job information includes a print quality 601, an output paper size 602, presence / absence of date 603, layout information 604, and an ID (image ID) 605 of an image to be output. The job information may further include information such as the presence / absence of image correction processing.

  The multifunction device 1 analyzes the job information, sets the output condition, and refers to the image ID included in the job information. In steps S507 and S508, the multi function device 1 requests the digital camera 2 for an image with the image ID included in the job information, and acquires the image with the image ID included in the job information from the digital camera 2. The processes in steps S507 and S508 are repeated for the number of image IDs included in the job information. The multifunction device 1 performs decoding processing and drawing of the image acquired from the digital camera 2 and prints it on paper.

  In step S504, the print capability information notified from the multifunction device 1 to the digital camera 2 is as shown in FIG. FIG. 7 is a configuration diagram of an example of print capability information transmitted from the multifunction device to the digital camera. The print capability information includes print quality 701, output paper size 702, and output layout information 703.

  For example, in the conventional multi-function peripheral, when the maximum paper size (maximum paper size) among the paper sizes that can be output on one sheet in the own machine is A4 size, the output paper size 702 included in the printing capability information. A paper size of A4 size or smaller is set. Therefore, in the conventional direct printing system, it is not possible to make a print request by designating a paper size larger than the maximum paper size that can be output with one sheet in the multifunction device 1, and the enlargement continuous shooting function of the multifunction device 1. Could not be used.

  On the other hand, in the multifunction device 1 according to the present invention, when the maximum paper size that can be output with one sheet is A4 size in the own device, the paper size that can be output with one sheet in the own device (for example, A4 size) is set. A paper size (for example, A3 size or A2 size) larger than the maximum paper size possible by combining a plurality of sheets is set as a printable paper size 702 included in the printing capability information.

  As described above, in the direct print system according to the present invention, a paper size larger than the maximum paper size that can be output on one sheet in the multifunction device 1 is output to the printing capability information notified from the multifunction device 1 to the digital camera 2. Included as possible paper size. Therefore, the digital camera 2 can make a print request by designating a paper size larger than the maximum paper size that can be output on one sheet in the multifunction device 1, and uses the enlarged continuous shooting function of the multifunction device 1. be able to.

  When the multifunction device 1 according to the present invention receives job information from the digital camera 2 in step S506, the multifunction device 1 performs processing according to the procedure shown in FIG. FIG. 8 is a flowchart illustrating an example of the processing procedure of the multifunction peripheral that has received the job information.

  When job information is received from the digital camera 2, the process advances to step S801, and the print command analysis unit 104 of the multifunction machine 1 analyzes the received job information. In step S802, the divided drawing control unit 103 determines whether or not the paper size to be output from the digital camera 2 is larger than the maximum paper size that can be printed on one sheet in its own machine. judge.

  If the paper size to be output from the digital camera 2 is not larger than the maximum paper size that can be printed on one sheet in the own apparatus, the divided drawing control unit 103 proceeds to step S803 and performs normal printing. Select. In step S804, the image output unit 106 acquires the image with the image ID included in the job information from the digital camera 2, performs image decoding processing and drawing, and performs the output included in the job information. Print on paper.

  If the paper size to be output from the digital camera 2 is larger than the maximum paper size that can be printed on one sheet in the own device, the divided drawing control unit 103 proceeds to step S805, and the enlargement sequence is increased. Select printing with the copy function. The divided drawing control unit 103 determines how many sheets (divided number) the image with the image ID included in the job information from the digital camera 2 is divided.

  In step S806, the division drawing control unit 103 controls the output setting control unit 105, the image output unit 106, and the paper feeding unit 107 to set the number of divided images of the image ID included in the job information from the digital camera 2. Accordingly, the image is divided and drawn so as to be divided and drawn on a divided number of sheets.

  Therefore, the multi-function device 1 outputs a paper having a paper size larger than the maximum paper size of the self-device included in the job information on a plurality of papers combining paper sizes that can be printed on one paper. Size paper can be formed and images can be printed.

  In step S805, the divided drawing control unit 103 determines the paper size to be divided and drawn according to the procedure shown in FIG. FIG. 9 is a flowchart illustrating an example of a processing procedure for determining the paper size to be divided and drawn.

  In step S901, the divided drawing control unit 103 lists paper sizes when the output paper size included in the job information is divided into integers. The split drawing control unit 103 lists not only the maximum paper size that can be printed on one sheet in the own machine, but also other paper sizes that can be printed on one sheet in the own machine. For example, when the A3 size is designated as the output paper size, the multifunction device 1 having the maximum paper size A4 size lists A4 size, A5 size, A6 size, and the like.

  In step S902, the divided drawing control unit 103 selects the listed paper sizes from the largest one as a candidate for the paper size. In step S903, the split drawing controller 103 determines whether the paper size selected as a candidate is set in the paper feed tray.

  If the paper size selected as a candidate is set in the paper feed tray, the split drawing control unit 103 proceeds to step S906, and determines whether the paper of the paper size selected as a candidate is out of paper, in other words, selected as a candidate. It is determined whether a sheet of the specified sheet size is set in the sheet feed tray. If it is not out of paper, the divided drawing control unit 103 proceeds to step S907, and determines the paper size selected as a candidate in step S902 as the paper size to be divided and drawn.

  If the paper size selected as a candidate is not set in the paper feed tray in step S903, and if the paper of the paper size selected as a candidate is out of paper in step S906, the divided drawing control unit 103 performs step S903. Returning to S902, the next candidate for the paper size is selected and the process continues.

  In step S902, when there is no next candidate for the paper size, the divided drawing control unit 103 proceeds to step S904, and determines the largest one of the paper sizes listed in step S901 as the paper size to be divided and drawn. Since the paper of the paper size to be divided and drawn determined in step S904 is not set in the paper feed tray, the multi function device 1 notifies the user to set the paper on the operation panel P or the like.

  Proceeding to step S905 following step S904 or S907, the division drawing control unit 103 controls the output setting control unit 105, the image output unit 106, and the paper feeding unit 107, and applies the digital camera to the paper of the determined paper size for division drawing. The image decoding process and the drawing are performed so that the image of the image ID included in the job information from 2 is divided and drawn.

  Since the multifunction device 1 selects the listed paper sizes in order from the largest, as the paper size candidates, the image of the image ID included in the job information can be divided and drawn with the minimum number of sheets. Further, by taking into account the current state of the paper feed tray, the multi-function device 1 can prevent printing from being performed due to the absence of paper size or paper.

  FIG. 10 is an image diagram of an image divided and drawn on a plurality of sheets. FIG. 10A shows an example in which an A2 size image is divided and drawn on two A3 size sheets in the multifunction machine 1 having a maximum sheet size of A3 size. FIG. 10B shows an example in which the A2 size image is divided and drawn into one A3 size sheet and two A4 size sheets in the MFP 1 having the maximum sheet size of A3 size.

  In addition to FIG. 10A, the multi-function device 1 having a maximum paper size of A3 size can separately draw an A2 size image on four A4 size papers or eight A5 size papers. FIG. 10A shows an example of split drawing using a single paper size.

  In addition to FIG. 10B, the multifunction device 1 having a maximum paper size of A3 size draws an A2 size image by dividing it into two A4 size papers and four A5 size papers, or an A2 size image. Can be divided and drawn into one sheet of A3 size, one sheet of A4 size, and two sheets of A5 size. FIG. 10B illustrates an example in which divided drawing is performed using a plurality of types of paper sizes.

  In the example of FIG. 10B, for example, it is initially determined that two A3 size sheets are divided and drawn. However, when one A3 size sheet is printed, the A3 size sheet runs out of sheets. For example, two sheets of A4 size paper can be substituted. In this case, the multifunction device 1 performs the processing procedure shown in the flowchart of FIG. 9 in units of division when dividing and rendering one image.

  In the direct print system according to the present invention, the print capability information includes a paper size larger than the paper size that can be printed on one sheet in the multifunction device 1 (paper size corresponding to a multiple of the paper size that can be handled by the multifunction device 1). To the digital camera 2. The digital camera 2 that has received the print capability information is in a state where it can make a print request by designating a paper size larger than the paper size that can be printed on one sheet in the multifunction device 1.

  When the multifunction device 1 receives a print request specifying a paper size larger than the paper size that can be printed on one sheet in the multifunction device 1, the multifunction device 1 uses the plurality of sheets of paper size designated by the digital camera 2. Realize with. Therefore, the direct printing system according to the present invention can provide a printing environment with higher functionality than the standard of the communication format related to direct printing common to each company.
