Description

  The present invention relates to direct printing between an input device and an output device, and describes a display method of user interface information between devices and a control method of the device.

  With the spread of digital cameras, data stored in the card is read directly from the card throttle provided in the printer body via a recording medium such as a Compact Flash (registered trademark) (CF) card, and the host PC There is an increasing demand for output from a so-called photo direct printer (PD printer) that directly performs printing without using a printer. Furthermore, the PD printer directly uses the data in the digital camera using the digital camera and the universal serial bus (USB) instead of the recording medium via the recording medium, so that data can be recorded on the printer side. A PD printer system that performs the above processing and performs recording is also realized.

  These PD printers have an image processing function called a controller unit inside the printer, and ordinary printers perform processing such as image rendering, rasterization, color conversion, quantization, and print control command generation performed on the host PC side. All of this is performed by this controller unit, and the generated data is sent to the engine unit. The engine unit reads the generated data, interprets the print control command and print data, and performs mechanical control and recording such as paper feed and carriage movement necessary to record the image on the actual non-recording medium. Controls such as application of head drive pulses and transmission of data to the recording head are performed. Control in these engine units is the same as when data is received from the conventional host PC in the engine unit. Such PD printers are also in demand with the spread of digital cameras.

  When performing direct photo printing with a PD printer without using a host PC, various types of prints made by the user using the host PC, such as the selection of image data to be printed, the number of copies to be printed, and the output layout, are performed by the host PC. The setting is performed in a device that performs photo direct printing (see Patent Document 1).

  Specifically, in the case of direct printing by a single PD printer that reads and outputs data via a recording medium, the user sets it based on information displayed on the user interface that is normally displayed on the display provided in the printer, Then, an instruction to start the printing operation is given.

Also, in a PD printer system that uses a digital camera and a universal serial bus (USB) or the like to directly process data into data that can be recorded on the printer side using data in the digital camera, the PD printer system performs recording. A user usually makes a setting based on information displayed on a user interface displayed on a display device provided with a digital camera, and gives an instruction to start a printing operation.
JP 2004-096688 A

  Using a digital camera and a universal serial bus (USB), the PD printer directly uses the data in the digital camera to process data that can be recorded on the printer side, and displays the camera in a PD printer system that performs recording. If a situation occurs in which data transfer is interrupted for some reason such as a paper feed error on the PD printer after issuing print execution instructions from the device, the user goes to the printer once, After the situation has been improved, it is necessary to give a transfer restart instruction again by operating the display on the camera, which is the only user interface.

In order to solve the above problems, the invention related to the present application is
Image data based on user interface information displayed on the display means of one device when image data is transferred by connecting an input device typified by a digital camera and an output device or information processing device typified by a PD printer After the transmission start instruction, the user interface information is displayed on the display means of the other device when a transfer middle state occurs for some reason in the other device, and the transfer restart instruction can be performed. Provide a way to do it.

  This invention can solve the above-mentioned problems by providing the following configuration (1).

  (1) When transferring image data by connecting an input device to an output device or an information processing device, after the image data transmission start instruction based on user interface information displayed on the display means of one device, the other A control method characterized in that user interface information is also displayed on a display means of a device and transmission control can be performed.

  When printing directly from an input device such as a digital camera to an output device such as a PD printer, if both devices are equipped with a display, print settings and print start instructions are displayed on the display means on the input device. The user interface information is displayed based on the displayed user interface information. When a transfer interruption state occurs for some reason in the printer, the user interface information is displayed on the display means of the device, and the transfer restart instruction can be issued. As a result, the operating user can confirm the defect information on the display on the printer side, and after resolving the problem, return to the digital camera and perform the resuming operation on the printer side without performing the resuming operation.
