And, promptly clap and promptly beat driver 51 according to carried out promptly clapping the initialization process of promptly beating from the indication of AP53 after, obtain the ability relevant information such as (Capability) that is had with printer 3 from printer 3.So-called ability (Capability) for example is can be by the printing image quality of printer prints, paper size, two-sided/single face etc.
At first, in step S11, with after digital camera 5 is connected, AP53 promptly beats driver 51 and sends promptly to clap and promptly beat initialization command promptly clapping at printer 3.In step S12, after bat in sight is promptly beaten driver 51 and received this order, return notified to AP53.
At this constantly, AP53 receives at after promptly the response of initialization command is promptly played in bat, temporarily ends task.That is, at this constantly, the OS of digital camera 5 has discharged the task of AP53.Therefore, even when digital camera 5 moves under single task OS, other tasks also can be moved.
In step S21, with notified turn back to AP53 after, promptly clap and promptly beat the initialize process that driver 51 is carried out PTP (Picture Transfer Protocol).
In step S23, PTP initialize process is and then promptly clapped and is promptly beaten driver 51 and will send the DPS_Configure-print-Service order, in step S24, receives this response from printer 3.
Then, if printer 3 is ordered the information of notifying the state that could print of expression printer with DPS_NotifyDeviceStatus in step S25, then in step S26, promptly clap and promptly beat driver 51 this is responded.
Here, in step S27, promptly clap and promptly beat driver 51 and do not wait for indication, and printer 3 is sent the DPS_GetCapability order from AP53.DPS_GetCapability order is the order that is used to obtain the relevant information of the ability (Capability) that had with printer 3.
In step S28, promptly clap and promptly beat driver 51 and obtain response from printer 3 at the DPS_GetCapability order.Promptly clap and promptly beat driver 51 project of ability (Capability) appointment, send the DPS_GetCapability order at printer 3.Then, as its response, obtain the information of specified project.Therefore, for the ability (Capability) that obtains a plurality of projects, i.e. bat is promptly beaten driver 51 and is specified obtained entry name respectively, repeatedly sends the DPS_GetCapability order.
In step S29, the information of the ability (Capability) that obtains from printer 3 is stored in the Capability storage part 55.
Thus, digital camera 5 can be obtained the information of ability (Capability) in advance from printer, it is remained in the Capability storer 55.
The information of ability (Capability) for example is: the print quality information of support (is printed default value, benchmark, high-quality etc.), paper size (is printed default value, A4, the L version, 4 * 6 etc.), the sheet type of using according to paper size (is printed default value, common paper, printing paper etc.), layout information according to paper size (is printed default value, do not have to cut apart non-flanged is arranged, two cut apart, four cut apart etc.), file type (is printed default value, Exif/JPEG, JPEG, GIF etc.), support information (the ON that the band date prints, OFF etc.), support information (the ON that filename is printed, OFF etc.), support information (the ON that the optimization of image is printed, OFF etc.), appointment will be fixed as the support information (A4 of the fixed measure printing of which kind of size with the image that paper size is differently printed, the L version, 4 * 6 etc.), and the support information (ON of image segmentation printing, OFF etc.) etc.
Here, the order that driver 51 is sent is promptly played in promptly clapping of step S23 and S27, promptly beats driver 51 and gives an order and end task by promptly clap at every turn.That is, give an order if driver 51 is promptly beaten in i.e. bat, then OS is released.Therefore, during wait-for-response, OS can handle other task.
Then, if AP53 has received promptly to clap and promptly beats after initialization command notified through the stipulated time in step S12, then AP53 promptly beats driver 51 and sends Capability and obtain order promptly clapping in step S13.Obtain in the order at this Capability, specify AP53 to wish the project that obtains.
Receive that the i.e. bat that Capability from AP53 obtains order promptly beats driver 51, in step S14, from obtaining in advance and keep reading the information of appointed project the Capability storage part 55 of information of appointed project, and in step S15, return this information to AP53.
