Description

  The present invention relates to a printing technique.

  When the printer receives a plurality of print target data (content data), the received content data is temporarily stored, and printing processing is sequentially performed. Here, in order to preferentially print specific content data, the user has to check the detailed setting information of the printer and reset necessary items.

  In addition, there is a system that preferentially prints content data from a user when the distance between the user and the printer is short. For example, in Patent Document 1, as the electric field strength of the wireless LAN from a device that has transmitted content data is higher, the printer preferentially prints the content data from the device.

JP 2006-227795 A

  However, if the user confirms the detailed setting information of the printer and resets necessary items, the operation is complicated. Further, if the order of printing content data is changed according to the electric field strength of the wireless LAN, the order of printing content data may be changed regardless of the user's intention.

  In order to solve the above problems, the present invention provides a technique for printing print data according to the user's intention by using close proximity wireless communication when the printing apparatus holds a plurality of print data. .

  The printing apparatus of the present invention includes a receiving unit that receives print data, a printing unit that prints the print data received by the receiving unit, a communication unit that performs close proximity wireless communication, and a receiving unit that receives information from an information processing device. The communication unit communicates with the information processing apparatus in a state where the printing apparatus holds the first print data that has been received and the second print data that has been received by the receiving unit prior to the first print data. And control means for causing the printing means to print the first print data when started.

  According to the present invention, when the printing apparatus holds a plurality of print data, the print data can be printed according to the user's intention by using the proximity wireless communication.

<Embodiment 1>
FIG. 1 shows a system configuration diagram of this embodiment. Reference numeral 101 denotes a printer as a communication apparatus. Reference numeral 102 denotes a digital camera as a communication partner apparatus of the printer 101. When the distance between the printer 101 and the digital camera 102 is within several centimeters, Peer to Peer communication (peer-to-peer) can be performed via the proximity wireless communication 103. In the present embodiment, TransferJet (trademark) using an induced electric field is used as the close proximity wireless communication 103. However, the present invention is not limited to this, and the close proximity wireless communication 103 may be NFC (Near Field Communication) using electromagnetic induction or IrDA using infrared rays.

  Reference numeral 104 denotes a PC (personal computer). The printer 101 and the PC 104 are connected via a network 105 via a wire 106 (Ethernet).

  FIG. 2A is a hardware configuration diagram of the printer 101. Reference numeral 201 denotes a CPU (Central Processing Unit) that controls the entire printer 101. A memory 202 stores a program and the like which will be described later. The memory 202 further stores a print information table 601 as shown in FIG. The print information table 601 includes the name of the print data (file name or URL indicating the location of the print data), identification information of the transmission source of the print data, and priority. A printing unit 204 described later prints (prints out) print data in descending order of priority. In the present embodiment, the higher the priority value, the higher the priority.

  Reference numeral 203 denotes a communication unit for performing communication conforming to TransferJet. Communication unit 203 includes an antenna (not shown). A printing unit 204 performs printing. Reference numeral 205 denotes a display unit for notifying (presenting) various information to the user. The display unit 205 may notify the user of various types of information by voice using a speaker (not shown) or the like.

  FIG. 3A is a functional block diagram realized when the CPU 201 of the printer 101 reads out a program stored in the memory 202. A part or all of these functional blocks may be combined into one functional block. Moreover, you may comprise some or all of these functional blocks as hardware, such as ASIC.

  Reference numeral 301 denotes a connection unit that performs connection processing with a communication partner (digital camera) using the communication unit 203. Reference numeral 302 denotes a measurement unit that measures electric field strength. When the measurement unit 302 measures an electric field strength of a predetermined value or more, the connection unit 301 performs a connection process with a communication partner. However, when the connection unit 301 transmits a message to the communication partner and detects that this message has reached the communication partner (for example, receives Ack), connection processing with the communication partner may be performed. Here, Ack is an abbreviation for Acknowledgment.

  Reference numeral 303 denotes a disconnection unit that disconnects communication with a communication partner using the communication unit 203. When the measurement unit 302 measures that the electric field intensity is less than a predetermined value for a predetermined time or longer, the disconnecting unit 303 disconnects communication with the communication partner. However, when the connection unit 301 transmits a message to the communication partner and the message does not reach the communication partner more than a certain number of times, the communication with the communication partner may be disconnected.

  A detection unit 304 detects connection by the connection unit 301 and disconnection by the disconnection unit 303.

  A reception unit 305 receives content data (print data) from a communication partner using the communication unit 203. The receiving unit 305 may receive image data from a communication partner and convert the received image data into print data.

  A processing unit 306 sequentially processes (prints) a plurality of content data received by the receiving unit 305 using the printing unit 204. The processing unit 306 sequentially performs processing (printing here) from content data having a higher priority value set in the content data. When there are a plurality of pieces of content data having the same priority, the processing unit 306 performs processing with priority from content data received earlier (FIFO, First In First Out).

  Reference numeral 307 denotes a management unit that manages the order in which the processing unit 306 processes content data. The management unit 307 manages a print information table as shown in FIG. The print information table is stored in the memory 202. The management unit 307 further includes a setting unit 308 that sets the priority assigned to each content data. By the setting unit 308 changing and resetting the priority given to each content data, the management unit 307 can change the processing order of the content data by the processing unit 306. In addition, the setting unit 308 stores the reset priority in the memory 202.

  Reference numeral 309 denotes an acquisition unit that uses the communication unit 203 to acquire a device identifier (ID) of a communication partner. The acquisition unit 309 stores the acquired device identifier in the memory 202. A comparison unit 310 compares the latest device identifier acquired by the acquisition unit 309 with a device identifier that has been received in the past and is already stored in the memory 202. Reference numeral 311 denotes a display control unit that displays on the display unit 205 the time until the processing unit 306 processes the content data. The display control unit 311 may further display the time on a display unit 254 (described later) of the communication partner.

  FIG. 2B is a hardware configuration diagram of the digital camera 102. Reference numeral 251 denotes a CPU that controls the entire digital camera 102. Reference numeral 252 denotes a memory for storing programs and the like which will be described later. Reference numeral 253 denotes a communication unit for performing communication compliant with TransferJet. Communication unit 253 includes an antenna (not shown). Reference numeral 254 denotes a display unit for notifying the user of various information.

  FIG. 3B is a functional block diagram realized by the CPU 251 of the digital camera 102 reading out a program stored in the memory 252. A part or all of these functional blocks may be combined into one functional block. Moreover, you may comprise some or all of these functional blocks as hardware, such as ASIC.

  A connection unit 351 detects that the communication partner has entered the communication range of the close proximity wireless communication 103 using the communication unit 203 and connects to the communication partner. A notification unit 352 notifies the communication partner of a device identifier (ID for identifying the digital camera 102) using the communication unit 203. A transmission unit 352 transmits print data to a communication partner using the communication unit 203. The transmission unit 353 converts image data previously selected by the user into print data and transmits the print data. However, the present invention is not limited to this, and the transmission unit 353 may convert all image data stored in the memory 252 of the digital camera 102 into print data and transmit the print data. If the printer 101 can convert image data into print data, the transmission unit 353 may transmit the image data to the printer 101 as it is. Reference numeral 354 denotes a disconnection unit that disconnects communication with the communication partner. Reference numeral 355 denotes a detection unit that detects connection by the connection unit 351 and disconnection by the disconnection unit 354.

  FIG. 4A shows a flowchart realized by the CPU 201 of the printer 101 reading out a program stored in the memory 202. In the printer 101, in parallel with this flowchart, the printing unit 204 performs printing according to the priority indicated in the print information table 601 in accordance with an instruction from the processing unit 306. When there are a plurality of print data having the same priority, the printing unit 204 prints with priority from the print data received earlier. When the printing unit 204 performs printing, the memory 202 deletes the printed print data from the print information table 601. If there is no print data, the printing unit 204 does not perform printing. FIG. 4B will be described in the second embodiment.

  FIG. 5A shows a flowchart realized by the CPU 251 of the digital camera 102 reading a program stored in the memory 252. FIG. 5B will be described in the second embodiment. Here, as an initial state, the printer 101 and the digital camera 102 are arranged at positions sufficiently distant from each other, and the close proximity wireless communication 103 cannot be performed. Further, the printer 101 has already received print data from the PC 104 via the wire 106 and stores the print data in the memory 202. Further, the memory 202 stores a print information table 601 (FIG. 6A) corresponding to the received print data.

  When the user brings the printer 101 and the digital camera 102 close to each other, the printer 101 and the digital camera 102 enter the communication range of the close proximity wireless communication 103, and the connection unit 301 performs a connection process with the digital camera 102 (S401). The connection unit 351 of the digital camera 102 also performs connection processing with the printer 101 (S501). Note that the operation in which the user brings the printer 101 and the digital camera 102 closer is realized when the user touches the printer 101 with the digital camera 102.

  When the connection is completed, the notification unit 352 of the digital camera 102 notifies the printer 101 of a device identifier (ID for identifying the digital camera 102) (S502). The acquisition unit 309 of the printer 101 receives this device identifier from the digital camera 102 (S402). The comparison unit 310 compares the device identifier received in step S402 with the device identifier received in the past and already stored in the memory 202 (S403). As a result of the comparison, if the device identifier received in step S402 matches the device identifier received in the past and already stored in the memory 202, the process proceeds to step S404. If the device identifiers do not match, the process proceeds to step S405. From this comparison, the printer 101 can confirm whether or not the digital camera 102 is reconnected. Here, since there is no device identifier received in the past and already stored in the memory 202, it is determined that the device identifiers do not match, and the process proceeds to step S405.

  In step S405, in accordance with an instruction from the CPU 201, the memory 202 updates the stored device identifier to the device identifier received in step S402. Note that the memory 202 may store the device identifier received in step S402 in addition to the device identifier already stored. Thereby, in step S403, the comparison unit 310 can compare with a plurality of device identifiers that have been connected in the past.

  Next, when there is untransmitted print data, the transmission unit 353 of the digital camera 102 transmits the print data to the printer 101 (S503, S504). Here, the transmission unit 353 converts the image data previously selected by the user into print data and transmits the print data. Further, the receiving unit 305 of the printer 101 confirms whether print data has been received from the digital camera 102 (S406). If the print data has been received, the process proceeds to step S407. If the print data has not been received, the process proceeds to step S410.

  Here, since the printer 101 has received print data from the digital camera 102, the memory 202 stores the received print data in accordance with an instruction from the CPU 201 (S407). Further, the management unit 307 writes the name of the received print data, the identification information of the print data transmission source, and the priority in the print information table 601 (S408). In this way, the print information table 601 is updated from the table shown in FIG. 6A to the table shown in FIG. Here, the setting unit 308 sets “1” which is a default value as the priority.

  After storing the print data, the display unit 205 of the printer 101 displays a waiting time until the received print data is printed by the printing unit 204 according to an instruction from the display control unit 311 (S409). Here, the display unit 205 performs the display shown in FIG. Thereby, the user can know the time until printing. The display unit 205 may further display the number of print data waiting for print processing and the number of prints. Thereby, the user can know the printing status in more detail. Further, the display control unit 311 may transmit the waiting time information to the digital camera 102 and display the same content on the display unit 254 of the digital camera 102. Thus, the user can obtain information from any one of the printer 101 and the digital camera 102. Even if the printer 101 is not equipped with a display unit, the user can obtain information.

  Further, the detection unit 304 of the printer 101 confirms whether or not the close proximity wireless communication 103 with the digital camera 102 has been disconnected (S410). If disconnected, the process returns to step S401, and if not disconnected (that is, if communication is continued), the process returns to step S406. Further, the detection unit 355 of the digital camera 102 confirms whether or not the close proximity wireless communication 103 with the printer 101 is disconnected by the disconnection unit 354 (S505). If it has been cut, the process returns to step S501. If it has not been cut, the process returns to step S503.

  Here, in order to preferentially print the print data transmitted from the digital camera 102, the user separates the printer 101 from the digital camera 102 (detachment). Accordingly, the cutting unit 303 of the printer 101 and the cutting unit 354 of the digital camera 102 disconnect the close proximity wireless communication 103. The printer 101 returns to step S401, and the digital camera 102 returns to step S501.

  Thereafter, the user brings the printer 101 and the digital camera 102 closer again (retouch).

  In the printer 101, the process proceeds to step S403 through steps S401 and S402. Here, since the printer 101 is reconnected to the digital camera 102, the device identifier received in step S402 matches the device identifier received in the past and already stored in the memory 202. Accordingly, the process proceeds to step S404, and the setting unit 308 increases the priority of the print data stored as a queue (queue) in the print information table among the print data received from the communication partner having the matched device identifier. Here, the setting unit 308 increments the priority of all print data received from the digital camera 102 by one. Note that only the priority of the print data received at the previous connection may be increased. The setting unit 308 may set the priority to a predetermined value (for example, 3) that is higher than the priority value of print data received from another communication partner (here, the PC 104). The setting unit 308 may set the priority according to the type of communication interface. Alternatively, the time from disconnection to reconnection with the digital camera 102 may be measured, and the setting unit 308 may increase the priority only when reconnection is made within a predetermined time. Further, when it is confirmed that the print data selected as the print target by the digital camera 102 is the same as that before retouching, the setting unit 308 may increase the priority of the print data. Further, when the digital camera 102 recognizes that the print data has been transmitted (NO in step S503) and no print data has been transmitted, the priority of all the print data received from the digital camera 102 by the setting unit 308 is set. It may be increased by one.

  In this way, the priority of the print data from the digital camera 102 is increased as shown in FIG. 6C, and the priority is higher than the print data from the PC 104. Therefore, the user can obtain a printed matter of the print data transmitted by the digital camera 102 without waiting for the print data received from the PC 104 to be printed.

  In the embodiment described above, the printer 101 determines reconnection between the printer 101 and the digital camera 102. However, the present invention is not limited to this, and the priority may be increased by detecting that the printer 101 and the digital camera 102 have been touched for a predetermined time or longer (communication is continued). Specifically, after the printer 101 receives print data in step S406, the display unit 205 performs the display shown in FIG. If it is detected that the touch has been made for a predetermined time (for example, 5 seconds) after the display, the printer 101 increases the priority of the print data from the digital camera 102 that has been touched. Even if it does in this way, the same effect can be acquired.

  Moreover, you may make it preset the priority according to a communication interface. For example, the priority is set to 1 for print data received by Ether, and the priority is set to 3 for print data received by TransferJEt. Even in this way, the user can acquire the printed matter of the print data transmitted by the digital camera 102 without waiting for the print data received from the PC 104 to be printed.

  Further, the order of the print information table 601 may be changed instead of changing the priority. For example, the object of the present application can also be achieved by changing from FIG. 6B to FIG. 6D. Further, according to one retouch, the order may be increased by one as shown in FIGS. 6B to 6E.

  The function of the management unit 307 may be provided in a print server (not shown) independent of the printer 101. In this case, the printer 101 notifies the print server that the digital camera 102 has been reconnected, and the print server updates the print information table. Thereafter, the printer 101 can perform the printing process according to an instruction from the print server, thereby achieving the object of the present application.

  As described above, the user can preferentially print the data transmitted from the digital camera by repeating touch and detach between the digital camera and the printer. That is, the printer responds to print requests from users near the printer rather than users near the PC accessing the printer over the network (ie, the user can be assumed to be far from the printer). Respond with priority and print. Therefore, the user near the printer can acquire his / her printed matter without waiting for the print data transmitted from the PC over the network to be printed.

  Further, the present invention is not limited to printing, and can be applied to cases where image data is sequentially displayed and moving image data and music data are sequentially reproduced.

  In the above-described embodiment, the priority is increased according to reconnection, but the priority may be decreased (for example, the priority is set to 0). Thereby, for example, even if the PC 104 transmits the print data E after the digital camera 102 transmits the print data D, the printer 101 prints the print data E first. Accordingly, the printing order can be changed according to the intention of the user of the digital camera 102.

<Embodiment 2>
In the first embodiment, the printer 101 determines reconnection with the digital camera 102 and changes the order in which the content data is printed. In the second embodiment, the digital camera 102 determines reconnection with the printer 101 and changes the order in which the content data is printed.

  Since the system configuration diagram of the present embodiment is the same as that of the first embodiment, the description thereof is omitted here. Further, the hardware configuration of the printer 101 and the hardware configuration of the digital camera 102 are the same as those of the first embodiment, and thus description thereof is omitted here.

  FIG. 8A is a functional block diagram realized when the CPU 201 of the printer 101 reads out a program stored in the memory 202. Functional blocks similar to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted here. A part or all of these functional blocks may be combined into one functional block. Moreover, you may comprise some or all of these functional blocks as hardware, such as ASIC.

  A notification unit 801 notifies a device identifier of the printer 101 (an ID for identifying the printer 101). A confirmation unit 802 confirms a request from a communication partner.

  FIG. 8B is a functional block diagram realized by the CPU 251 of the digital camera 102 reading out a program stored in the memory 252. Functional blocks similar to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted here. A part or all of these functional blocks may be combined into one functional block. Moreover, you may comprise some or all of these functional blocks as hardware, such as ASIC.

  Reference numeral 851 denotes an acquisition unit that acquires the device identifier of the printer 101. Reference numeral 852 denotes a comparison unit that compares and collates the latest device identifier acquired by the acquisition unit 851 with the device identifier received in the past and already stored in the memory 252. A request unit 853 requests the communication partner to change the processing order of print data.

  FIG. 4B shows a flowchart realized by the CPU 201 of the printer 101 reading a program stored in the memory 202. FIG. 5B shows a flowchart realized by the CPU 251 of the digital camera 102 reading a program stored in the memory 252.

  Note that, as an initial state, the printer 101 and the digital camera 102 are disposed at positions sufficiently separated from each other, and the close proximity wireless communication 103 cannot be performed. Further, the printer 101 has already received print data from the PC 104 via the wire 106 and stores the print data in the memory 202. Further, the memory 202 stores a print information table 601 (FIG. 6A) corresponding to the received print data.

  When the user brings the printer 101 and the digital camera 102 close to each other, the printer 101 and the digital camera 102 enter the communication range of the close proximity wireless communication 103, and the connection unit 301 performs connection processing with the digital camera 102 (S451). The connection unit 351 of the digital camera 102 also performs connection processing with the printer 101 (S551).

  When the connection is completed, the notification unit 801 of the printer 101 notifies the digital camera 102 of the device identifier of the printer 101 (S452). The acquisition unit 851 of the digital camera 102 receives this device identifier (S552). The comparison unit 310 compares the device identifier received in step S552 with the device identifier received in the past and already stored in the memory 252 (S553). As a result of the comparison, if the device identifier received in step S552 matches the device identifier received in the past and already stored in the memory 202, the process proceeds to step S554. If the device identifiers do not match, the process proceeds to step S555. Here, since there is no device identifier that has been received in the past and is already stored in the memory 252, it is determined that the device identifiers do not match, and the process proceeds to step S555.

  In step S555, in response to an instruction from the CPU 201, the memory 252 updates the stored device identifier to the device identifier received in step S552. Next, when there is untransmitted print data, the transmission unit 353 of the digital camera 102 transmits the print data to the printer 101 (S556, S557). On the other hand, the receiving unit 305 of the printer 101 receives print data from the digital camera 102 and stores it in the memory 202 (S453). Further, the management unit 307 of the printer 101 writes the name of the received print data, the identification information of the print data transmission source, and the priority in the print information table 601 (S454). In this way, the print information table 601 is updated from the table shown in FIG. 6A to the table shown in FIG. When the print data is stored, the display unit 205 of the printer 101 displays a waiting time until the received print data is printed by the printing unit 204 according to an instruction from the display control unit 311 (S455). Here, the display unit 205 performs the display shown in FIG.

  Thereafter, the confirmation unit 802 of the printer 101 confirms whether or not a priority change request has been received from the digital camera 102 (S456). If a change request has not been received, the process proceeds to step S457. If a change request has been received, the process proceeds to step S458. Here, since the change request has not been received, the process proceeds to step S457.

  In step S457, the detection unit 304 of the printer 101 confirms whether the close proximity wireless communication 103 with the digital camera 102 has been disconnected. If it has been cut, the process returns to step S451, and if it has not been cut, the process returns to step S453. Further, the detection unit 355 of the digital camera 102 confirms whether or not the close proximity wireless communication 103 with the printer 101 is disconnected by the disconnection unit 354 (S558). If it has been cut, the process returns to step S501. If it has not been cut, the process returns to step S556.

  Here, in order to preferentially print the print data transmitted from the digital camera 102, the user separates the printer 101 from the digital camera 102 (detachment). Accordingly, the cutting unit 303 of the printer 101 and the cutting unit 354 of the digital camera 102 disconnect the close proximity wireless communication 103. Thereafter, the user brings the printer 101 and the digital camera 102 closer again (retouch).

  In the printer 101, the process proceeds to steps S456 through steps S451 to S455. In the digital camera 102, the process proceeds to step S553 via steps S551 and S552. Here, since the digital camera 102 is reconnected to the printer 101 after being disconnected, the device identifier received in step S552 matches the device identifier received in the past and already stored in the memory 202. Accordingly, the process advances to step S554, and the request unit 853 transmits a change request for increasing the priority of print data to the printer 101. Note that the print data whose priority is to be changed is designated by transmitting a change request to the printer 101 including index information for identifying the print data whose priority is to be changed. Further, the change request may be transmitted only when it is confirmed that there is no change in the print data selected by the user before and after the reconnection. Thus, when the user reselects new print data, the priority can be prevented from being increased. Here, the request unit 853 requests the printer 101 to increase the priority of the print data D by one.

  The confirmation unit 802 of the printer 101 confirms that the change request from the digital camera 102 has been received (S456), and proceeds to step S458. In step S458, the setting unit 308 changes the priority of the designated print data. If there is no designation of print data, the setting unit 308 changes the priority of all print data received from the communication partner. Here, the setting unit 308 increases the priority of the print data D from the digital camera 102 by one.

  In this way, the priority of the print data from the digital camera 102 is increased as shown in FIG. 6C, and the priority is higher than the print data from the PC 104. Therefore, the user can obtain a printed matter of the print data transmitted by the digital camera 102 without waiting for the print data received from the PC 104 to be printed.

  In step S554, the digital camera 102 may operate as follows. That is, the request unit 853 requests to cancel the print processing of print data that has not been printed by the printer 101. Further, the transmission unit 353 transmits a print request with a high priority added to the printer 101. Thus, even when the printer 101 does not support the priority change instruction from the digital camera 102, the priority can be increased.

  According to the present invention, a computer-readable recording medium having recorded thereon software program codes for realizing the above-described functions is supplied to a system or apparatus, and the system or apparatus reads and executes the program code stored in the recording medium. Also good. The above-described object can also be achieved by the operation of the apparatus in this way.
