  FIG. 13 is a diagram showing the configuration of the RAM 904 of the MFP. Reference numeral 1301 denotes the entire RAM. The work memory 1302 is a memory reserved for program execution. The image processing buffer 1303 is an area used as a temporary buffer for image processing. The device state storage unit 1304 stores various information regarding the current state of the MFP 300. The error state 1305 stores a state relating to an error of the MFP 300. The error-related status is, for example, a low ink warning, no ink error, paper jam error, no paper warning, print image image failure warning, read image failure error, or network disconnection warning. These warnings and errors are associated with the degree of influence on the printing function and the degree of influence on the reading function. For example, when there is no ink error, the printing function cannot be used, but the reading function can be used. In the case of a network disconnection warning, the function that uses the network cannot be used, but the setting change or reading function performed by the device alone can be used. The remaining ink amount 1306 stores the model number of the currently installed ink tank and the remaining ink amount. The model number of the ink tank is updated at the timing when the ink tank is attached. The ink remaining amount is updated every time ink is used. The next estimated activation time 1307 stores an estimated activation time when the next activation is performed when the power is turned off. The activation time of the MFP varies greatly depending on the state. For example, the power state of the MFP includes a hard off state, a soft off state, a normal activation state, and a sleep state.

  The hard-off state is a state in which the supply of power is interrupted, and it takes a long time to turn on the power and change from the hard-off state to the normal startup state. The soft-off state is a state in which the power is partially turned on but the main program is not started, and can be started earlier than the hard-off state. In the sleep state, the portion that consumes a large amount of power is turned off, and other programs and mechanisms are operating, so that the normal start state can be returned relatively quickly. Another factor that varies the startup time is the error state of the device. For example, when it is detected that the nozzles of the recording head are clogged by the ink jet recording method, the next activation is performed after a long recovery process. In addition, when the amount of light of the scanner is low, the scanner is activated after performing an adjustment operation. Thus, the estimated activation time for the next activation is determined by the state transition of the power source and the state of the device. The other 1308 stores other device states such as the current memory usage, hardware temperature, and consumable information. The other 1309 stores other RAM data.

For example, when communicating with a smart phone by NFC, the identifier of the smart phone is stored as a list 1405. When communicating with the camera by NFC, camera identifiers are stored as a list 1404.

  When the smartphone and the WLAN are connected by P2P, identification information for connecting by the WLAN is stored. For example, when WPS (Wi-Fi Protected Setup) is used for WLAN connection, WPS Credential authentication information is stored. When the smartphone is connected with Bluetooth, OOB authentication information is stored. When connected to the server device via the LAN, the network information of the server device is stored. Setting information 1406 stores setting information of the MFP apparatus. For example, menu items such as a print mode, recording head correction information in the ink jet recording method, and the like are stored. Other 1407 stores other nonvolatile information.

  FIG. 15 is a diagram illustrating a configuration of the NFC memory 1005 of the MFP 300. Reference numeral 1501 denotes the entire NFC memory. The device state storage unit 1502 copies the contents of the device state storage unit 1304 at a predetermined timing. Accordingly, the error state 1503, the remaining ink amount 1504, and the next estimated activation time 1505 correspond to the error state 1305, the remaining ink amount 1306, and the next estimated activation time 1307, respectively. The job storage unit 1506 is an area used when various jobs are submitted from the portable communication terminal apparatus 200 to the MFP 300 by NFC. A print job 1507 stores print jobs in a queue. For example, the print setting and the link destination to the image are stored. A scan job 1508 stores a scan job in a queue. For example, reading settings are stored. In the FAX job 1509, FAX jobs are stored in a queue. For example, the FAX setting including the telephone number of the transmission destination and the communication image quality, and the link destination to the image when the image has already been read are stored. The setting change job 1510 stores setting change jobs in a queue. For example, a job related to change of setting items of the main body is stored.

The WPS CrEndential authentication information includes SSID, Encryption, Auth Type, Network Key, MAC address, and the like. The OOB authentication information includes BTaddress, Hash C, Randomizer R, and the like. Authentication is performed by passing these pieces of information from the authentication source to the authentication destination, and peer-to-peer communication by WLAN or Bluetooth becomes possible.

  FIG. 20 is a flowchart illustrating a procedure in which the NFC unit operates as an initiator. Each process shown in FIG. 20 is executed by the CPU or the like of the apparatus in which the NFC unit is mounted. First, in S2001, all NFC units operate as targets and wait for a command from the initiator. Next, in S2002, the NFC unit can be switched to an initiator in response to a request from an application that controls communication complying with the NFC standard. When the NFC unit responds to the request to switch to the initiator, in S2003, the application selects either the active mode or the passive mode and determines the transmission rate. Next, in step S2004, the initiator detects the presence of an RF field output by a device other than its own device. When the presence of an external RF field is detected, the initiator does not generate its own RF field. If the presence of the external RF field is not detected, the process proceeds to S2005, and the initiator generates its own RF field. Through the above steps, the NFC unit starts operating as an initiator.

  FIG. 21 is a diagram showing a sequence for exchanging data in the passive mode. FIG. 24 is a flowchart showing the flow of FIG. Based on FIG. 21, it demonstrates, matching with each process of FIG. Each process shown in FIG. 24 is executed by the CPU or the like of the apparatus in which the NFC unit is mounted. Hereinafter, a case where the first NFC unit 2101 operates as an initiator and the second NFC unit 2102 operates as a target will be described. First, in S2101, the first NFC unit 2101 performs single device detection and identifies the second NFC unit 2102 (S2401). That is, in S2101, the first NFC unit 2101 and the second NFC unit 2102 detect the presence of each other. Next, in S2102, the first NFC unit 2101 transmits its own identifier, transmission / reception bit transmission rate, effective data length, and the like as an attribute request to the other party (S2402). The attribute request has a general-purpose byte and can be arbitrarily selected and used. When receiving a valid attribute request, the second NFC unit 2102 transmits an attribute response in S2103. Here, transmission from the second NFC unit 2102 is performed by load modulation, and data transmission by load modulation is indicated by a dotted arrow in the figure.

  After confirming the valid attribute response (S2403), the first NFC unit 2101 can change the parameters of the subsequent transmission protocol by transmitting a parameter selection request in S2104. The parameters included in the parameter selection request are, for example, a transmission rate and an effective data length. When receiving a valid parameter selection request, the second NFC unit 2102 transmits a parameter selection response in S2105 to change the parameters (S2404 to S2409). Note that S2104 and S2105 may be omitted if no parameter change is performed.

  Next, in S2106, the first NFC unit 2101 and the second NFC unit 2102 exchange data by a data exchange request and a data exchange response (S2410). When a data exchange request and a data exchange response are made, information on an application possessed by the communication partner can be transmitted as data. If the data size is large, it can be divided and transmitted.

  When the data exchange is completed, the process proceeds to S2107, and the first NFC unit 2101 transmits either a selection release request or a release request (S2411, S2414). When the selection cancellation request is transmitted, the second NFC unit 2102 transmits a selection cancellation response in S2108 (S2412). Upon receiving the selection cancellation response, the first NFC unit 2101 releases the attribute indicating the second NFC unit 2102 (S2413), and returns to S2101. When the release request is transmitted, the second NFC unit 2102 transmits a release response in S2108 and returns to the initial state (S2415). If the first NFC unit 2101 receives the release response, the target has been completely released, and may return to the initial state.

  FIG. 22 is a diagram showing a sequence for exchanging data in the active mode. FIG. 25 is a flowchart showing the flow of FIG. Based on FIG. 22, description will be made in association with each step of FIG. 25. Each process shown in FIG. 25 is executed by the CPU or the like of the apparatus in which the NFC unit is mounted. Hereinafter, a case where the first NFC unit 2201 operates as an initiator and the second NFC unit 2202 operates as a target will be described. First, in S2201, the first NFC unit 2201 transmits its own identifier, transmission / reception bit transmission rate, effective data length, and the like as an attribute request (S2501). When receiving a valid attribute request, the second NFC unit 2202 transmits an attribute response in S2202. Here, the transmission from the second NFC unit 2202 is performed by the RF field generated by itself. For this reason, the first and second NFC units stop outputting the RF field when the data transmission ends.

  After confirming the valid attribute response (S2502), the first NFC unit 2201 can change the parameters of the transmission protocol by transmitting a parameter selection request in S2203 (S2504 to 2508). Parameters included in the parameter selection request are a transmission rate and an effective data length. When receiving a valid parameter selection request, the second NFC unit 2202 transmits a parameter selection response in S2204 to change the parameter. As in the passive mode, S2203 and S2204 may be omitted if no parameter change is performed.

  Next, in S2205, the first NFC unit 2201 and the second NFC unit 2202 exchange data by a data exchange request and a data exchange response (S2509). When a data exchange request and a data exchange response are made, information for the application can be transmitted as data. If the data size is large, it can be divided and transmitted.

  When the data exchange is completed, the process proceeds to S2206, and the first NFC unit 2201 transmits either a selection release request or a release request (S2509, S2510). When the selection cancellation request is transmitted (S2510), the second NFC unit 2202 transmits a selection cancellation response in S2207 (S2511). Upon receiving the selection cancellation response, the first NFC unit 2201 releases the attribute indicating the second NFC unit 2202 (S2512). Thereafter, in S2208, the first NFC unit 2201 transmits an activation request to another target whose identifier is known (S2513). The target that has received the activation request transmits an activation response in S2209 (S2514), and returns to S2201. When the release request is transmitted in S2206 (S2515), the second NFC unit 2202 transmits a release response in S2207 and returns to the initial state (S2516). When receiving the release response, the first NFC unit 2201 may return to the initial state because the target is completely released.

  FIG. 23 is a diagram illustrating state transition of a target in NFC. The POWER-OFF state S2301 represents a power-off state. In the state of S2301, when the target is placed in the magnetic field H larger than the threshold value Hmin, the state moves to the SENSE state S2302. In the SENSE state S2302, the target is waiting for an instruction from the initiator. When the target receives the detection request or the all device activation request, the target shifts to the RESOLUTION state S2303 and returns a detection response. If another command is received, it remains in the SENSE state S2302.

  In the RESOLUTION state S2303, single device detection is used. When a valid selection request is received as a result of single device detection, the target returns a selection response to the initiator and enters the SELECTED state S2304. If another command is received, the process returns to the SENSE state S2302.

  In the SELECTED state S2304, the target recognizes an attribute request, parameter selection request, or valid proprietary instruction. When the target receives a valid sleep request or deselection request, it enters SLEEP state S2305. If any other command is received, the process returns to the SENSE state S2302. When the target in the SLEEP state S2305 receives an all device activation request, it returns a detection response and then moves to the RESOLUTION * state S2306. If any other command is received, it remains in the SLEEP state S2305.

  The RESOLUTION * state S2306 is substantially the same state as the RESOLUTION state S2303, and single device detection is used. If a valid selection request is received, the target transitions to the SELECTED * state S2307. If any other command is received, the process returns to the SLEEP state S2305. The SELECTED * state S2307 is substantially the same as the SELECTED state S2304, and the target recognizes an attribute request, a parameter selection request, or a valid proprietary instruction. When a valid sleep request or selection cancel request is received, the state transits to the SLEEP state. If any other command is received, it falls back to the SLEEP state.

  FIG. 26 is a diagram illustrating a sequence for performing data transfer by switching between NFC and WLAN. Since NFC has a relatively low communication speed of several hundreds bps, authentication or the like is performed using NFC, and high-capacity data can be efficiently transferred by using high-speed WLAN. FIG. 26 is a diagram illustrating an example of a so-called push type in which image data existing on the portable communication terminal device 2601 is transferred mainly by the portable communication terminal device 2601 for printing by the printing device 2602. . The processing on the portable communication terminal device side shown in FIG. 26 is executed by the CPU 802, for example, and the processing on the printing device side is executed by the CPU 902, for example.

  In step S2601, in order to establish NFC communication, the NFC communication unit 2603 serves as an initiator and detects the NFC communication unit 2605 as a target. When the NFC communication unit 2605 is correctly detected, in S2602, the NFC communication unit 2605 transmits a detection response. Although FIG. 26 shows a case where the portable communication terminal device 2601 is an initiator, the printing device 2602 may be an initiator based on an input from the operation display unit 305 or the like. When the detection response is correctly received, the NFC communication unit 2603 transmits an attribute request for performing NFC communication in S2603. Upon receiving the attribute request, the NFC communication unit 2605 returns an attribute response in S2604. Here, in the attribute request and the attribute response, the NFC-IDs of the initiator and the target are transmitted, respectively, and the communication partner is specified by this ID.

  In S2605, mutual authentication is performed, and an encryption key or the like for data encryption can be passed. Note that this mutual authentication need not be performed when it is not necessary to pass the encryption key. In step S2606, the NFC communication unit 2603 requests the NFC communication unit 2605 for information on communication protocols that can be used by the printing apparatus 2602. This request includes information on a communication protocol that can be used by the portable communication terminal apparatus 2601. When the NFC communication unit 2605 receives this request, the WLAN communication of the portable communication terminal apparatus 2601 can be used. Can be recognized. In step S <b> 2607, the NFC communication unit 2605 responds to the request received in step S <b> 2606 with information on the communication protocol that can be used. This allows each other's devices to recognize each other's available communication protocols.

  Here, it is assumed that the WLAN, which is a recognized protocol other than NFC, can transfer data at a higher speed than NFC, and it is determined by the portable communication terminal device 2601 that is the initiator to perform communication by switching to the WLAN. The determination for switching may be performed by the printing apparatus 2602. In this case, in S2608 and S2609, information such as an address specifying a communication partner necessary for performing communication by WLAN is exchanged. Thereafter, the process proceeds to S2610, and the NFC communication unit 2603 transmits a request to switch from NFC communication to WLAN communication. Upon receiving the switching request, the NFC communication unit 2605 responds to the request in S2611.

  If a correct switching response is obtained, switching is performed from the NFC communication unit 2603 to the WLAN communication unit 2604 in step S2612, and from the NFC communication unit 2605 to the WLAN communication unit 2606 in step S2613. After switching, the NFC communication unit 2603 transmits a release request in S2614. The NFC communication unit 2605 that has received the release request transmits a release response in S2615 and ends the NFC communication.

  After S2616, WLAN communication is performed based on the information for WLAN communication exchanged in S2608 and S2609. First, in S2616, the WLAN communication unit 2604 confirms with the WLAN communication unit 2606 whether or not data transfer is possible. Here, the content to be confirmed is, for example, a free space for temporarily storing an image to be transferred to the printing apparatus 2602. After receiving the confirmation request, the WLAN communication unit 2606 transmits a response to the confirmation in S2617. If it is determined that a correct response is obtained and data transfer is possible, the WLAN communication unit 2604 transmits image data present in the portable communication terminal device 2601 to the WLAN communication unit 2606 in S2618. In this way, large capacity data can be transferred using a higher speed communication protocol.

  FIG. 27 is a diagram illustrating an example of a so-called pull type in which image data existing on the portable communication terminal apparatus 2701 is transferred mainly by the printing apparatus 2702 in order to print the image data by the printing apparatus 2702. The procedures of S2701 to S2715 are the same as S2601 to S2615 of FIG. After switching from the NFC standard communication to the WLAN communication, first, in S2716, a data acquisition confirmation request is transmitted from the WLAN communication unit 2706 to the WLAN communication unit 2704. The content confirmed here is, for example, the data size scheduled to be transferred by the portable communication terminal device 2701. After receiving the confirmation request regarding the transfer data, the WLAN communication unit 2704 transmits a response in S2717. If a correct response is obtained and it is determined that data transfer is possible in consideration of the free capacity of the printing apparatus, the WLAN communication unit 2706 requests image data in S2718. When the correct request is received, the WLAN communication unit 2704 transmits the image data requested in S2719. After the image data is transmitted in S2618 or S2719, the printing apparatus 2602 or 2702 starts printing.

  FIG. 28 is a diagram illustrating an example in which the server apparatus has image data to be printed by the print job transmitted by the portable communication terminal apparatus 2801. S2801 to S2806 are the same as S2701 to S2706. The server apparatus 2807 stores image data to be printed. S2801 to S2805 are the same as the description of S2701 to S2705. In step S2806, the NFC communication unit 2805 receives a print job from the NFC communication unit 2803 (job reception). The print job includes print settings, image data name, path information to the image data, information on the storage location when the image data is in a storage location different from the portable communication terminal device 2801, and authentication information on the storage location. The information necessary for printing is included. The print settings include information necessary for print settings such as print size and print quality.

  When the printing apparatus 2802 executes the received print job (job execution) and refers to the link destination of the image data to be printed in the print job and determines that the image data is in the server apparatus 2807, Image data is acquired in the processing after S2809. In step S2807, the NFC communication unit 2803 transmits a release request. Upon receiving the release request, the NFC communication unit 2805 returns a release response in S2808 and ends the NFC communication. In step S2809, the printing apparatus 2802 transmits a connection request to the server apparatus 2807 via the network 100 using WLAN. The server apparatus 2807 transmits a connection response in S2810 to notify that the connection is possible. In S2811, the WLAN communication unit 2806 requests image data, and in S2812, the server apparatus 2807 transmits the image data. When the image data is received, the printing apparatus 2802 transmits a communication disconnection request in S2813, and the server apparatus 2807 returns a communication disconnection response in S2814 and ends the communication.

  When executing the sequence of FIG. 28, if the printing apparatus 2802 is in an error state such as a paper jam, the user of the portable communication terminal apparatus 2801 may transmit a print job without noticing. Further, if the printing apparatus 2802 is in an error state when a print job is transmitted to the printing apparatus 2802 after the print setting is performed on the portable communication terminal apparatus 2801, operations such as image selection performed so far are useless. Become.

  Therefore, in the present embodiment, the process shown in FIG. 29 is executed to prevent the user of the portable communication terminal apparatus 2801 from performing a useless operation. Each process illustrated in FIG. 29 is executed by the CPU 902 of the printing apparatus 2802. In step S2901, it is determined whether the printing apparatus 2802 is in an error state. Here, the determination of the error state means whether or not the printing apparatus 2802 is in a state that affects printing. For example, an out-of-ink error, a paper jam error, and the like. A warning that may affect other than an error may be determined as an error state. For example, such warnings are low warnings such as low ink warnings, warnings about running out of paper, etc., and print images that are likely to occur during printing, or that can be printed but have an effect on image quality. There is a defect warning. If such a state is detected, the process proceeds to S2902, and the state notification application 1 is activated.

  The status notification application 1 is an application for notifying a device that sends a print job by NFC of an error when the printing device 2802 is in a state of affecting printing such as an error. An error may be displayed on the display unit 911 of the printing apparatus 2802. In S2903, the status notification application 1 shifts the NFC communication unit 2805 to the initiator mode, and proceeds to S2904. If it is detected in S2904 that the NFC device has approached (closed), the process proceeds to S2905. The NFC device approaching here may be either the initiator mode or the target mode. When an NFC device in the initiator mode approaches, the NFC device of the printing device 2802 returns to the target mode and communicates with the portable communication terminal device 2801. On the other hand, when the NFC device in the target mode approaches, the NFC device of the printing device 2802 communicates with the portable communication terminal device 2801 as it is. If communication is established, the process advances to step S2905 to notify the status of the printing apparatus 2802, and the process advances to step S2906 to end the process.

  In the present embodiment, since the user of the portable communication terminal device 2801 can know in advance the error of the printing device 2802 by performing the processing shown in FIG. 29, it is possible to perform useless operations such as image selection. Can be prevented. For example, in a state where no operation is performed on the portable communication terminal device, it is possible to know whether or not printing is possible only by bringing the user close to the printing device to be printed. In addition, since error information is preferentially notified even when an operation other than printing is performed, the user can grasp the error state of the printing apparatus 2802. In addition, since the power consumption increases when the mode is changed to the initiator mode, control that does not change to the initiator mode may be performed in the sleep mode (power saving mode) described above.

  By executing the sequence shown in FIG. 28, the portable communication terminal apparatus 2801 can print the image data in the server apparatus 2807. However, since the portable communication terminal apparatus 2801 carries the portable terminal after transmitting the print job, the communication with the printing apparatus 2802 is disconnected, and the printing progress status or the print execution result cannot be known. Also, if the previous print execution failed, the user of the portable communication terminal apparatus 2801 may not notice the print failure and may send another print job one after another. . In particular, when printing cannot be performed due to a problem in the image data of the server apparatus 2807, or when printing cannot be performed because the server apparatus 2807 cannot be connected to the server apparatus 2807, there is no problem with the printing apparatus 2802. Error information is not displayed on the display unit 911 2802.

  Here, when there is a problem with the image data, for example, when specific image data could not be decoded, when there was no image data, or when the size of the image data was different from the user specification, etc. It is. In this case, considering that an unspecified number of users use the printing apparatus 2802, displaying an error message indicating the failure of the print job corresponding to the specific user is not related to the error. It will cause confusion.

  FIG. 30 is a flowchart illustrating a procedure of processing for notifying an error caused by a print job in this embodiment. By executing the processing in FIG. 30, it is possible to notify only the person who has submitted the print job that the image data has failed due to an error or the like. S3000 in FIG. 30 is the state of the printing apparatus 2802 at the time when printing is completed in S2814. Each process shown in FIG. 30 is executed by the CPU 902 of the printing apparatus 2802 or the like.

  In step S3001, it is determined whether the execution of the print job has succeeded or failed. If it is determined that the process has succeeded, it is not necessary to notify the user of an error, so that the process proceeds to S3010 and the process ends. When it determines with having failed, it progresses to S3002 and starts the status notification application 2. FIG. The status notification application 2 is an application for notifying the error by NFC communication when the previous print execution result performed by the printing apparatus 2802 is an error. In S3003, the NFC communication unit 2805 is shifted to the initiator mode, and the process proceeds to S3004.

  In S3004, when it is detected that the NFC device has approached, the process proceeds to S3005. In step S3005, the NFCID of the portable terminal close to the printing apparatus 2802 is acquired. In step S3006, it is determined whether the portable communication terminal device that has been close in step S3004 is a device in which the previous printing was an error. This determination is made, for example, by storing the NFCID of the portable communication terminal device that has input the print job in a storage area such as a RAM when a previous print error occurs (for example, an image data format error), and S3005. It may be compared with the NFCID acquired in (1). As another comparison means, it is also possible to use a uniquely determined identifier such as a serial number of a portable communication terminal device, a unique identification number determined by an application, or a user ID. In addition, if non-unique information such as a product type and an application type is matched, it may be determined that the device has an error in printing.

  If it is determined in S3006 that the device is an error, the process proceeds to S3007. If it is determined that the device is not an error, the process proceeds to S3009. In step S3008, a new print job is not accepted from the portable communication terminal device in close proximity in step S3004. In step S3008, the previous print status (ie, print error) is notified to the adjacent portable communication terminal device, and the process advances to step S3010 to end the process. On the other hand, in step S3009, a new print job is accepted, the process proceeds to step S3010, and the process ends.

  By executing the processing shown in FIG. 30, a user who has failed the previous print job can know the failure before submitting the next print job. Can be prevented. In addition, since a user who is not related to a failed print job does not know useless notifications, the possibility of misunderstanding is reduced.

  According to the above embodiment, when an error occurs in the device, the error information is transmitted using the device as an initiator, so that the user of the mobile terminal can be notified of the error appropriately.

  Note that the timing of entering the mode as the initiator may be when NFC communication with the mobile terminal is interrupted, or may be the initiator after disconnecting the NFC when an error occurs. The determination for disconnecting the NFC may be performed by the mobile terminal or the printing apparatus.

  The present invention is also realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, or the like) of the system or apparatus reads the program. It is a process to be executed. Further, the number of computers that execute the program may be one, or a plurality of computers may cooperate to execute the program. Furthermore, hardware such as a circuit that executes a part of the program may be provided, and the hardware and the computer that executes the software may cooperate to execute the processing described in this embodiment.
