Description

  The present invention relates to a printing control apparatus, a printing control system, a printing apparatus, a printing control method, and a program, and more specifically, a printing control apparatus that transmits and holds print data to a plurality of printing apparatuses having a hold printing function, and printing The present invention relates to a control system, a printing apparatus, a printing control method, and a program.

  A printing apparatus (printer) having a hold printing function is generally used. According to the hold printing function, the print data instructed by the user is temporarily held (held) on the hard disk in the printer. When the user inputs a password or the like to the printer at a desired timing, the print data can be printed out.

  By using the hold printing function, only a specific user who knows the password can print out at a desired timing, so that security of important documents and confidential documents can be protected. Furthermore, when print data is no longer needed after a print instruction is given, the print data can be deleted from the printer as it is without being printed out.

  On the other hand, companies and the like are increasingly using a PC (personal computer) that transmits print data, a print server, and a plurality of printers connected to a network. In such a network environment, when considering providing a printing service to a user who moves in an office or factory, it is not always efficient for a user who frequently moves to use only a specific printer as an output destination. is not. For example, it is often more efficient to use a printer in the middle of the travel route to the destination as the output destination.

For example, Patent Document 1 proposes a printing service for users who move in a network environment. This determines a printer as an output destination in consideration of a user's movement route, movement time, printing time by the printer, and the like.

  However, in the case of the technique described in Patent Document 1, it is not considered to perform hold printing when a plurality of printers are connected in a network environment. That is, there is no conceivable use form in which a plurality of printers having a hold print function are connected to a network, and print data is transmitted to the printers on the network to hold the print data. For this reason, if the user forgets to instruct the printer on the network to print, the printed material will be left in the printer. If the printed material is a confidential document, it is important to a third party. Information may be leaked. This is even more so when a printer located at a remote location such as the user's destination is the output destination, as in Japanese Patent Application Laid-Open No. H10-228707.

  Further, when the print data is held in a plurality of printers on the network and the user prints out from a desired printer, the print data held in other printers on the network becomes unnecessary. Leaving this in the printer wastes disk space and is not desirable from a security standpoint. Conventionally, in order to delete print data from a printer, the user deletes the print data directly to the printer that sent the print data, or sends an instruction for deleting the print data of the printer from the user PC. There is a problem that it is necessary to cope with the method, and the deletion work is troublesome.

  The print server 1 includes a control unit 11 configured by a CPU, a ROM, a RAM, and the like to control the operation of the device, a storage unit 12 configured by a hard disk, a nonvolatile memory, and the like, and printers 2a to 2c and a PC 3 via a network. And a network I / F 13 for connecting to the network. Further, the control unit 11 corresponds to a print data storage management unit 111 that stores and manages the print data 121 transmitted from the PC 3 in the storage unit 12, and a printing apparatus extraction unit that extracts a printer as a transmission destination of the print data 121. A destination printer extraction unit 112, a transmission page allocation unit 113 for allocating pages to be transmitted to each printer, a print data transmission unit 114 for transmitting print data 121 to each printer, and a printer instructed by the user for printing If there is a print data deletion instruction unit 115 for sending a print data deletion command to another printer, and a user position information acquisition unit 116 for acquiring user position information.

  The units included in the control unit 11, that is, the print data storage management unit 111, the transmission destination printer extraction unit 112, the transmission page allocation unit 113, the print data transmission unit 114, the print data deletion instruction unit 115, and the user position information acquisition unit 116 are included. The print control program can be executed by the print server 1. The print control program is stored in the storage unit 12 or the like, read by the control unit 11 when the program is executed, and executed as appropriate.

  The PC 3 includes a control unit 31 configured by a CPU, a ROM, a RAM, and the like to control the operation of the device, an operation unit 32 for performing a print data transmission operation, and the printers 2a to 2c and prints via a network. A network I / F 33 for connecting to the server 1 is provided. Furthermore, the control unit 31 includes a print data transmission unit 311 that is a printer driver, and a mobile terminal information transmission unit 312 that transmits mobile terminal information regarding the mobile terminal 4. The print data transmission unit 311 transmits print data to the print server 1 in accordance with an operation instruction from the operation unit 32. The mobile terminal information transmitted by the mobile terminal information transmitting unit 312 includes information (e-mail address or the like) for accessing the mobile terminal 4 held by the user who transmitted the print data via the network.

  The portable terminal 4 having a GPS function includes a control unit 41 configured by a CPU, a ROM, a RAM, and the like to control the operation of the device, an operation unit 32 for performing various operations, and the print server 1 via a public line network. And a communication I / F 43 for connection to the network. Furthermore, the control unit 41 includes a user position information transmission unit 411 and transmits the position information acquired by the GPS function to the print server 1. This user position information may be transmitted in response to a request (inquiry) from the print server 1, or may be transmitted from the portable terminal 4 periodically or at an arbitrary timing.

  In FIG. 1, when the print server 1 receives print data 121 transmitted from the control unit 31 of the PC 3 on the network, the print data storage management unit 111 stores the print data 121 in the storage unit 12. In addition, the mobile terminal information 122 transmitted from the control unit 31 of the PC 3 is stored in the storage unit 12. When the print data 121 and the mobile terminal information 122 are stored in the storage unit 12, the transmission destination printer extraction unit 112 of the print server 1 prints the print data 121 based on the user position information acquired by the user position information acquisition unit 116. The printer which becomes the transmission destination of is extracted.

The user position information acquisition unit 116 identifies the mobile terminal 4 used by the user who transmitted print data from the PC 3 based on the mobile terminal information 122 in the storage unit 12, and the user position information (for example, latitude / Get longitude). When the user position information is acquired by the user position information acquisition unit 116, the user position information is stored in the storage unit 12 as a history. The acquisition of the user position information is not limited to the portable terminal of this example, and an information recording medium such as an IC card or RFID may be used.
Thereafter, the destination printer extraction unit 112 extracts two or more printers close to the user position. The position information of each printer is stored in advance in the storage unit 12, and a printer close to the user is extracted by comparison with the user position acquired by the user position information acquisition unit 116.

  The transmission page allocation unit 113 allocates the number of pages of print data to be transmitted to each printer extracted by the transmission destination printer extraction unit 112. For example, in the case of a high-speed printer, the print processing time after a print instruction to the high-speed printer may be shortened by increasing the number of pages of print data.

  The print data transmission unit 114 transmits the print data of the number of pages allocated by the transmission page allocation unit 113 to each printer. The print data transmission unit 114 causes each printer to hold the print data if there is an instruction for hold printing from the PC 3. Here, the print data transmission unit 114 may expand and transmit the print data in a bitmap format or the like common to each printer that is the transmission destination of the print data, or a printer language corresponding to each printer. (PDL: Page Description Language) information may be stored in advance, and the print data may be converted and transmitted according to the printer language of each printer. In the former case, transmission of print data is broadcast transmission that does not specify a printer, and in the latter case, it is multicast transmission that specifies each printer.

  When the print data deletion instructing unit 115 receives a print data print notification (print completion notification or print start notification) from the printer instructed by the user among the printers to which the print data transmission unit 114 has transmitted the print data, Instructs other printers on the network other than the printer to delete the print data. As a result, the print data stored in the other printer is automatically deleted.

Next, a configuration example of the printers 2a to 2c connected to the print server 1 will be described. Since the basic configuration is the same, the printer 2a is shown as a representative example.
The printer 2a includes an image forming unit 21 that performs print processing of print data, a control unit 22 that is configured by a CPU, a ROM, a RAM, and the like and that controls operation of the device, and an operation unit 23 that performs print data print operations and the like.

Further, the control unit 22 includes a print data storage management unit 221 for storing and managing the print data 241 transmitted from the print data transmission unit 114 of the print server 1 in the storage unit 24, and when a print instruction is given by the user. And a print notification unit 222 that transmits a print start notification or a print completion notification to the print server 1 or another printer.

  When the printer 2 a receives a print instruction for the print data 241 stored in the storage unit 24 from the user via the operation unit 23, the image forming unit 21 performs a print process for the print data 241. In the case of hold printing, the user inputs a password from a numeric keypad included in the operation unit 23, and the control unit 22 performs an authentication process. The password information related to the print data is transmitted from the print server 1 to each printer in advance together with the print data, and is held by each printer.

  When the printing process is completed by the image forming unit 21, the print notification unit 222 notifies the print server 1 of the completion of the printing process. At this time, the print notification unit 222 may notify the completion of printing not only for each job but for each page for which printing has been completed or for each predetermined page. Further, the print notification unit 222 may notify the print server 1 of the start of the printing process when the printing process is started by the image forming unit 21. Hereinafter, the print completion notification or the print start notification is referred to as a print notification. The print notification may include information regarding the print data amount (for example, print completion up to two pages) of the print data that has been printed.

  FIG. 2 is a diagram illustrating an example of a print data management table stored in the storage unit 12 of the print server 1. The print data transmission unit 114 of the print server 1 controls print data transmission processing based on the print data management table stored in the storage unit 12.

  The print data management table shown in FIG. 2 manages, for each print data, identification information of the mobile terminal, user position information, destination printer, transmission page, print data type, and the like. Note that position information (not shown) of each printer on the network is registered in advance in this print data management table, and if the user position information is known, the distance to each printer can be calculated. As a result, the print server 1 can extract a printer close to the current position of the user.

  According to this example, in the case of print data “001”, user location information is acquired from a portable terminal having an e-mail address (XXXXX.DELTA..DELTA..ne.jp). 5 pages are transmitted to the printer of the page and IP address 2, respectively. In this way, the print data transmission unit 114 may transmit a part of the print data to the printer according to the print order of the print data, and cause the printer to hold a part of the print data.

  FIG. 3 is a diagram for explaining an example of the flow of hold print processing according to the print control system of the present invention. In the case of the print server 1 shown in this example, when the user performs a printing operation from the PC 3, the print data is automatically transmitted to and stored in the printer closest to the current position of the user. Then, the user can print out desired print data simply by going to the nearest printer and performing an output operation.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S1), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S2). Further, the print server 1 acquires user position information from the portable terminal 4 (S3), and extracts the printer 2a located closest to the user position from among the plurality of printers 2a, 2b, and 2c.

  The print server 1 transmits the print data (here, all pages) stored in the storage unit 12 to the printer 2a that is the closest printer (S4). The printer 2a stores the print data received from the print server 1 in the storage unit 24 (S5). Then, the user inputs a password from the operation unit 23 of the printer 2a, and prints out necessary print data from the printer 2a (S6).

  FIG. 4 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 3, but when the user moves and the nearest printer changes, print data is sent to the nearest nearest printer and the print data is stored. However, all or part of the print data in the printer that is far from the user is deleted.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S11), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S12). Further, the print server 1 acquires user position information from the portable terminal 4 (S13), and extracts the printer 2a that is closest to the user position from among the plurality of printers 2a, 2b, and 2c.

  The print server 1 transmits the print data (here, all pages) stored in the storage unit 12 to the printer 2a which is the closest printer (S14). The printer 2a stores the print data received from the print server 1 in the storage unit 24 (S15).

Next, when the user moves and the nearest printer changes from the printer 2a to the printer 2b, the print server 1 transmits print data to the newly nearest printer 2b (S16). The printer 2b stores the print data received from the print server 1 in the storage unit (S17). As a result, the print data in the printer 2a that stores the print data but has become far from the user is deleted (S18). This is executed based on a deletion instruction from the print server 1.
Then, the user inputs a password from the operation unit of the printer 2b, and prints out necessary print data from the printer 2b.

  In the above process, the storage unit 12 stores a history regarding the user position information acquired by the user position information acquisition unit 116. When the user position information acquired by the user position information acquisition unit 116 is different from the previous user position information stored in the storage unit 12, the transmission destination printer extraction unit 112 performs printing based on the acquired user position information. A new printer (in this case, the printer 2b) as a data transmission destination is extracted. When a new printer is extracted by the transmission destination printer extraction unit 112, the print data deletion instruction unit 115 deletes the print data with respect to the printer (here, the printer 2a) extracted based on the previous user position information. Instruct.

  FIG. 5 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as that in the example of FIG. 3, except that print data is transmitted not only to the printer closest to the user, but also to a plurality of printers close to the user.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S21), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S22). Further, the print server 1 acquires user position information from the portable terminal 4 (S23), and extracts a plurality of printers located near the user position from among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user.

The print server 1 transmits the print data (here, all pages) stored in the storage unit 12 to the respective printers 2a, 2b, 2c (S24). Each printer 2a, 2b, 2c stores the print data received from the print server 1 in the storage unit (S25).
Then, the user inputs a password from any one of the printers 2a, 2b, and 2c, and prints out necessary print data from a desired printer.

  FIG. 6 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 5 except that only the first plurality of pages of print data is transmitted to a plurality of printers close to the user.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S31), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S32). Further, the print server 1 acquires user position information from the portable terminal 4 and extracts a plurality of printers located near the user position among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user. Here, the print data is 20 pages in total.

  The print server 1 transmits the first plurality of pages (here, 5 pages) of the print data stored in the storage unit 12 to the respective printers 2a, 2b, and 2c (S33). Each printer 2a, 2b, 2c stores the print data (for 5 pages) received from the print server 1 in the storage unit (S34).

In the above processing, the print data transmission unit 114 transmits a part of the print data to each printer 2a, 2b, 2c according to the print order of the print data, and holds a part of the print data in each printer 2a, 2b, 2c. Let
In this way, by storing not only all pages of print data but also the start page and several pages of print data from the start in advance in the printer, the storage capacity can be used more efficiently than if all print data is held in each printer. be able to.
When printing from the last page by face-up printing, several pages from the last page may be held in the printer in advance.
As described above, when transmitting the first plurality of pages of print data to a plurality of printers close to the user, the plurality of pages are transmitted in the printing order from the print start page regardless of the page number.

  FIG. 7 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 6 except that the transmission amount of print data is weighted according to the distance between the user and each printer.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S41), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S42). Further, the print server 1 acquires user position information from the portable terminal 4 and extracts a plurality of printers located near the user position among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user. Here, the print data is 20 pages in total.

  The print server 1 simultaneously transmits different amounts of print data among the print data stored in the storage unit 12 according to the distance between each printer 2a, 2b, 2c and the user (S43). Here, since the printer 2a is the closest printer, all 20 pages are transmitted, and since the printer 2b is the second closest printer, 10 pages are transmitted and the printer 2c is the third closest printer. Send 5 pages. The printers 2a, 2b, and 2c store the print data (20 pages, 10 pages, and 5 pages in this case) received from the print server 1 in the storage unit (S44).

  In the above processing, the print data transmission unit 114 varies the amount of print data transmitted to each printer 2a, 2b, 2c according to the distance between the user position based on the user position information and each printer 2a, 2b, 2c. . At this time, since the printer closest to the user position is highly likely to be printed out, the print output process can be efficiently performed by increasing the amount of print data to be stored.

  FIG. 8 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 6, but when the user is moving, the amount of print data transmitted to each printer is information related to the user's movement path, that is, from the user. Weighting is performed according to the distance to the printer, the moving speed of the user, and the moving direction of the user.

  In FIG. 8A, the printers 2a, 2b, and 2c are installed at an equal distance from the user. When the user is moving in the direction of the arrow in the figure at high speed (fast walking, running about), since the printer 2a is in the direction opposite to the moving direction, it is unlikely to be printed out and the print data is not transmitted at all. Not. Further, since the printer 2b is in the direction perpendicular to the moving direction, “50%” of the print data is transmitted. Further, since the printer 2c is in the same direction as the moving direction and the user moves at high speed, the printer 2c is most likely to be printed out. For this reason, “80%” of the print data is transmitted.

  In FIG. 8B, the printers 2a, 2b, and 2c are installed at an equal distance from the user. When the user is moving at a low speed (normal walking) in the direction of the arrow in the figure, since the printer 2a is in the direction opposite to the moving direction, “20%” of the print data is transmitted. Further, since the printer 2b is in the direction perpendicular to the moving direction and the user moves at a low speed, the printer 2b is most likely to be printed out. For this reason, “80%” of the print data is transmitted. Since the printer 2c is in the same direction as the movement direction, “50%” of the print data is transmitted.

In the above processing, the destination printer extraction unit 112 obtains information related to the user's movement route (the distance from the user to the printer, the movement speed of the user, the movement direction of the user) from the history of the user position information stored in the storage unit 12. Etc.). Then, based on the information related to the movement route, a printer that is a transmission destination of the print data is extracted.
Further, the print data transmission unit 114 weights the amount of print data to be transmitted to the printers 2a, 2b, and 2c extracted by the transmission destination printer extraction unit 112 based on information on the movement path.
Usually, it is considered that there is a high possibility that a print instruction is given to a printer on the movement path of the user. Therefore, it is possible to identify a printer that is highly likely to be instructed to print based on the information related to the movement route, and to increase the amount of print data to be transmitted in order of the highest possibility.

  FIG. 9 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 6, but after sending only the first plurality of pages of print data to each printer, when the printer instructed by the user performs print output, The print server 1 transmits the remaining pages of print data to the printer.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S51), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S52). Further, the print server 1 acquires user position information from the portable terminal 4 and extracts a plurality of printers located near the user position among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user. Here, the print data is 20 pages in total.

  The print server 1 transmits the first plurality of pages (here, 5 pages) out of the print data stored in the storage unit 12 to the printers 2a, 2b, and 2c (S53). Each printer 2a, 2b, 2c stores the print data (for 5 pages) received from the print server 1 in the storage unit (S54).

  Then, the user inputs a password from the operation unit 23 of the nearest printer 2a, and prints out necessary print data from the printer 2a (S55). When the user performs an output operation on the printer 2a, this print notification is transmitted to the print server 1, and the print server 1 transmits the remaining pages (6 to 20 pages in this case) of the print data to the printer 2a (S56). .

In the above process, when the plurality of printers 2a, 2b, and 2c hold a part of the print data, the print data transmission unit 114 receives a print notification from any one of the printers 2a, 2b, and 2c. The remaining print data is transmitted to the printer (in this case, the printer 2a).
As a result, the printer that has issued the print instruction can acquire the remaining print data while performing the print output of the print data of the start page and several pages from the start, so that the print output can be performed efficiently.

  FIG. 10 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 5, but when the user performs an output operation on any printer, the print notification is transmitted to the print server 1, and the print server 1 that has received the print notification. In that the other printer is instructed to delete the print data.

  Note that print data deletion processing for other printers may be performed between printers without using the print server 1. For example, when a print instruction is given to the printer 2a by a user operation, a print notification is transmitted from the printer 2a to the other printers 2b and 2c. In response to the print notification, the printers 2b and 2c delete the respective print data. This example is for the printer 2a, but the same applies when a print instruction is given to the printers 2b and 2c. In the example of FIG. 10, a case where print data deletion processing is performed between printers without using the print server 1 will be described.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S61), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S62). Further, the print server 1 acquires user position information from the portable terminal 4 and extracts a plurality of printers located near the user position among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user.

  The print server 1 transmits the print data stored in the storage unit 12 to the printers 2a, 2b, 2c all at once (S63). Each printer 2a, 2b, 2c stores the print data received from the print server 1 in the storage unit (S64).

  In this example, the user inputs a password from the operation unit 23 of the printer 2a, and prints out necessary print data from the printer 2a (S65). The printer 2a that has performed the print output transmits a print notification to the other printers 2b and 2c (S66), and the printers 2b and 2c that have received the print notification delete the respective print data from the storage unit.

  As described above, since the print data is held (held) in advance by a plurality of printers on the network close to the user, the user can print out the desired print data regardless of the print instruction of any printer nearby. . Furthermore, since print data of printers other than the printer for which the user has instructed printing can be automatically deleted, the storage capacity of the printer can be used efficiently, and confidential documents can be protected.

  FIG. 11 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. The basic processing flow is the same as in the example of FIG. 10, but when the user performs an output operation on any printer, the print notification and information on the amount of print data printed by the printer are displayed. The print server 1 that has received the information regarding the print data amount is instructed to delete other printed pages from the print server 1. Similarly to the example of FIG. 10, the print data deletion process for other printers may be directly performed between printers without using the print server 1. In the example of FIG. 11, a case where print data deletion processing is performed without using the print server 1 will be described.

  First, when the user performs a printing operation from the PC 3, all the print data is sent to the print server 1 (S71), and the print server 1 stores the print data from the PC 3 in the storage unit 12 (S72). Further, the print server 1 acquires user position information from the portable terminal 4 and extracts a plurality of printers located near the user position among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user.

  The print server 1 transmits the print data stored in the storage unit 12 to the printers 2a, 2b, and 2c all at once (S73). Each printer 2a, 2b, 2c stores the print data received from the print server 1 in the storage unit (S74).

  In the case of this example, the user inputs a password from the operation unit 23 of the printer 2a, and prints out necessary print data (here, up to two pages) from the printer 2a (S75). A print notification is transmitted from the printer 2a that has performed the print output to the other printers 2b and 2c (S76). This print notification includes information about the amount of print data that has been printed by the printer 2a (here, output up to two pages). When the printers 2b and 2c receive a print notification including information related to the print data amount that has been printed, the printers 2b and 2c delete up to two pages of the respective print data from the storage unit based on the print notification.

As another example, when the print data deletion instruction unit 115 receives a print notification from one of the plurality of printers 2a, 2b, and 2c (here, the printer 2a), the printer 2a included in the print notification Based on the information related to the print data amount that has been printed, the printers 2b and 2c other than the printer 2a may be instructed to delete the print data amount that has been printed by the printer 2a.
In this way, the print data holding time in other printers can be shortened by instructing deletion for each page that is no longer necessary, instead of deleting all the print data transmitted by simultaneous transmission.

  FIG. 12 is a diagram for explaining another example of the flow of hold printing processing according to the printing control system of the present invention. In the figure, 5 indicates an IC card for entering and leaving the room. In the case of this example, each printer is classified by area unit, and when the user leaves the area, the printer in the area deletes the stored print data.

First, the print server 1 needs to recognize where the user is located. In the area unit, it is possible to recognize the position of the user by a method other than the portable terminal. For example, the IC card 5 for entering / exiting each area can be used.
When the print server 1 recognizes that the user has entered the area A using the IC card 5, the print server 1 transmits print data to the printers 2a, 2b, and 2c in the area A. The printers 2a, 2b, and 2c hold the print data from the print server 1 in the storage unit.

  When the print server 1 recognizes that the user has left the area A by using the IC card 5, the print server 1 instructs to delete the print data stored in the printers 2a, 2b, and 2c in the area A ( S81). Further, when the user recognizes that the user has entered the area B using the IC card 5, the print data is transmitted to the printer 2d in the area B (S82).

  In the above process, the print server 1 uses the IC card 5 held by the user to recognize the user position information acquisition unit 116 that recognizes the area where the user is located, the transmission destination printer extraction unit 112 that extracts the printer in the recognized area, The print data received from the PC 3 is transmitted to the printer extracted by the transmission destination printer extraction unit 112, and the print data transmission unit 114 for holding the print data in the printer, and when it is detected that the user has left the area, it is in the area. A print data deletion instruction unit 115 that instructs the printer to delete the print data.

  FIG. 13 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. In this example, a system in which the PC 3 executes a series of transmission processes by the print server 1 in FIG. A description of the print data deletion process from the printer instructed by the user to another printer is omitted.

  First, the PC 3 acquires user position information from the user's portable terminal 4 (S91), and extracts a plurality of printers located near the user position from among printers on the network. Here, the printers 2a, 2b, and 2c are extracted in order from the closest to the user. When the user performs a printing operation from the PC 3, the print data is simultaneously transmitted to each printer 2a, 2b, 2c (S92). Each printer 2a, 2b, 2c stores the print data received from the PC 3 in the storage unit (S93).

  FIG. 14 is a diagram for explaining another example of the flow of hold print processing according to the print control system of the present invention. In this example, a system in which the printer 2a executes a series of transmission processes by the print server 1 in FIG. That is, the printer 2a includes a destination printer extraction unit 112, a transmission page allocation unit 113, a print data transmission unit 114, a print data deletion instruction unit 115, and a user position information acquisition unit 116 provided in the print server 1. This function can be executed. A description of the print data deletion process from the printer instructed by the user to another printer is omitted.

  First, when the user performs a printing operation from the PC 3, the print data is transmitted to the printer 2a (S101). The printer 2a stores the print data received from the PC 3 in the storage unit 24 (S102). The printer 2a acquires user position information from the portable terminal 4 (S103), and extracts a plurality of printers located near the user position from among printers on the network. Here, the printers 2b and 2c are extracted in order from the closest to the user.

  The printer 2a transmits the print data stored in the storage unit 24 to the printers 2b and 2c all at once (S104). Each printer 2b, 2c stores the print data received from the printer 2a in the storage unit (S105).

  FIG. 15 is a flowchart for explaining an example of the print control method by the print server 1 according to the present invention. This example will be described based on the system configuration shown in FIG. First, when the print server 1 receives print data and portable terminal information from the PC 3 (step S111), the print server 1 associates the print data with the portable terminal information and stores them in the storage unit 12 (step S112).

  Next, the print server 1 inquires of the mobile terminal 4 about the user position information (step S113), and receives the user position information from the mobile terminal 4 (step S114). Then, the print server 1 transmits the print data stored in the storage unit 12 to each printer 2a, 2b, 2c (step S115). It is determined whether or not a certain time has elapsed since the transmission of the print data (step S116). If the certain time has elapsed (in the case of YES), the process returns to step S113 to repeat from the user position information inquiry process. In step S116, if the predetermined time has not elapsed (in the case of NO), it is determined whether any of the printers 2a, 2b, 2c has received a print completion notification (step S117).

  If there is no print completion notification from any printer (NO) in step S117, the print server 1 proceeds to step S171 shown in FIG. The presence / absence of a print notification is determined by, for example, the presence / absence of a flag indicating a print notification. This print notification is not limited to a job unit, but may be for each page or for each predetermined page. In step S117, for example, when a print completion notification is received from the printer 2a (in the case of YES), the other printers 2b and 2c that have transmitted the same print data, or the same number of pages with the same print data. The other printers 2b and 2c that have been transmitted are requested to delete the print data (step S118), and the print data in the print server 1 is deleted (step S119).

  FIG. 16 is a flowchart for explaining an example of the print data transmission process in step S115 shown in FIG. First, the print server 1 determines whether or not there is user position information received last time (step S121). If there is no previous user position information (in the case of NO), the printer 1 is selected based on the current user position information. Two or more are extracted (step S122). Then, print data to be assigned to each printer is determined (step S123), and the print data is transmitted to each printer (step S124).

  In step S121, if there is previous user position information (YES), the print server 1 extracts a printer close to the user position (step S125), and extracts the printer extracted based on the previously received user position information. And whether the printer extracted this time is different (step S126).

  If the print server 1 determines in step S126 that the previous and current printers are different (in the case of YES), the print server 1 determines print data to be assigned to the currently extracted printer (step S127). Then, print data is transmitted to the printer extracted this time (step S128). If it is determined in step S126 that the previous and current printers are the same (NO), the print data is held as it is, and the process proceeds to “return”.

  Next, the print server 1 determines whether or not the print data of the previous printer is part or all (step S129). If the print data of the previous printer is all (all cases in the figure), the print server 1 Then, an instruction to delete all print data is transmitted (step S130). If the print data of the previous printer is a part (in the case of a part in the figure), an instruction to delete a part of the print data is transmitted to the previous printer (step S131).

  FIG. 17 is a flowchart for explaining an example of the print data allocation processing in steps S123 and S127 shown in FIG. First, the print server 1 allocates the first few pages of print data to each printer based on the print data management table and user position information shown in FIG. 2 (step S141).

  FIG. 18 is a flowchart for explaining another example of the print data allocation processing in steps S123 and S127 shown in FIG. First, the print server 1 assigns a larger number of pages of print data in order of the printer closer to the user position based on the print data management table and user position information shown in FIG. 2 (step S151).

  FIG. 19 is a flowchart for explaining the printer extraction process close to step S125 shown in FIG. First, the print server 1 determines, based on a flag or the like, whether or not to extract a printer based on the moving direction of the user (step S161). When the printer is extracted based on the user's moving direction (in the case of YES), the moving path is calculated from the previous user position and the current user position (step S162), and one or more close in the moving direction from the user position. The printer is extracted (step S163). In step S161, if the user's moving direction is not extracted (in the case of NO), one or more near printers are extracted based on the user position information (step S164).

  FIG. 20 is a flowchart for explaining processing when there is no print notification in step S117 shown in FIG. First, in the above-described step S117, if the print server 1 receives a print completion notification from one of the printers 2a, 2b, and 2c (for example, the printer 2a) (YES), the print server 1 remains from the printer 2a. It is determined whether or not there has been a request for print data (step S171).

  When there is a request for the remaining print data from the printer 2a in step S171 (in the case of YES), the print server 1 transmits the remaining print data to the requested printer 2a (step S172), and FIG. The process returns to step S117 and is repeated. In step S171, if there is no request for the remaining print data from the printer 2a (in the case of NO), it is determined whether the number of printed pages has been received from the printer 2a (step S173).

  In step S173, when the print server 1 receives the number of printed pages from the printer 2a (in the case of YES), the print server 1 returns to step S117 in FIG. 15 and repeats the processing. In step S173, when the number of pages that have been printed is not received from the printer 2a (in the case of NO), the process returns to step S116 in FIG. 15 and is repeated.

  FIG. 21 is a flowchart for explaining an operation example of the printer 2a according to the present invention. This example will be described based on the system configuration shown in FIG. First, the printer 2a determines whether or not print data has been received from the print server 1 (step S181). If the print data is received (YES), the print data is stored in the storage unit (step S182). The process returns to step S181 and is repeated. In step S181, if print data is not received (NO), it is determined whether there is a print command for the stored print data from the user (step S183). That is, it is determined whether or not a password has been input by the user in order to execute hold printing.

  If it is determined in step S183 that there is no print command from the user (NO), the printer 2a proceeds to step S201 shown in FIG. If it is determined in step S183 that there is a print command from the user (YES), printing of the print data is started (step S184), and it is determined whether the print data has all pages (step S185). .

  If the printer 2a determines in step S185 that there is no print data for all pages (in the case of NO), the printer 2a requests print data for the remaining pages from the print server 1 (step S186). The print data is received and the printing process is continued (step S187). If it is determined in step S185 that the print data has all pages (YES), the process proceeds to step S188.

  In the process of step S187, when printing is completed for each page or every predetermined page, a flag indicating completion of printing may be transmitted to the print server 1 as a print completion notification.

  Next, the printer 2a determines whether or not there is a print error or a print cancel instruction (step S188). If there is a print error or a print cancel instruction (in the case of YES), the number of pages that have been printed is determined. The print server 1 is notified (step S189), printing is stopped (step S190), and the process returns to step S181 to repeat the process. In step S188, if there is no print error or print stop command (NO), it is determined whether or not printing is finished (step S191).

  If it is determined in step S191 that printing has ended (YES), the printer 2a sends a print completion notification to the print server 1 (step S192), and returns to step S181 to repeat the processing. If it is determined in step S191 that printing has not ended (NO), the process returns to step S188 and is repeated.

  FIG. 22 is a flowchart for explaining processing when there is no print command from the user in step S183 shown in FIG. First, the printer 2a determines whether or not there is a print data deletion request from the print server 1 (step S201), and if there is a deletion request (in the case of YES), all of the print data requested to be deleted. Or a part is deleted from a memory | storage part (step S202), it returns to step S181 of FIG. 21, and a process is repeated. In step S201, when there is no deletion request (in the case of NO), the process returns to step S181 in FIG.

  In order to execute the flow described with reference to FIGS. 21 and 22, the printer 2 a includes a storage unit 24 that stores print data transmitted from the print server 1 and a print instruction for the print data stored in the storage unit 24. An operation unit 23 (corresponding to the print instruction unit of the present invention), an image forming unit 21 (corresponding to the print unit of the present invention) for executing print data print processing according to a print instruction from the operation unit 23, and image formation When the printing process by the unit 21 is interrupted, a print notification unit 222 is provided for notifying information on the amount of print data that has been printed before the printing is interrupted.

In this manner, even when printing is interrupted, the print server notifies the print server of the amount of data that has been printed, so the print server can request other printers to delete the amount of data that has been printed. Then, the user can go to another printer and print the remainder of the print data for which printing was interrupted from the other printer.
In addition, even if printing is interrupted due to an instruction to stop printing by the user or an error during printing, similarly, the user goes to another printer and the remaining print data from the other printer is interrupted. Can be printed.

  As described above, each embodiment has been described with a focus on each function in the print control apparatus of the present invention. However, the present invention also has a form as a print control method as described as a method for executing each step in the print control apparatus. Can take. Similarly to the print control apparatus having each function, a form as a print control program for causing a computer to function as a print control apparatus, or a form as a recording medium on which the print control program is recorded is also possible. .

  An embodiment of a recording medium storing a program and data for realizing a print control function according to the present invention will be described. Specific recording media include CD-ROM (-R / -RW), magneto-optical disk, DVD-ROM (-R / -RW / -RAM), FD, HD, BD, flash memory, memory card. In addition, a memory stick and various other ROMs and RAMs can be assumed, and the recording medium stores a program for causing the computer to execute the functions of the above-described embodiments of the present invention and realizing the print control function. To facilitate the realization of the function. Then, the recording medium as described above is mounted on an information processing apparatus such as a computer and the program is read by the information processing apparatus, or the program is stored in a storage medium provided in the information processing apparatus. By reading, the print control function according to the present invention can be executed.

  As described above, according to the present invention, two or more printing devices on the network close to the user position hold the print data in advance, so that the user issues a print instruction at any nearby printing device. In addition, desired print data can be printed out. Furthermore, since print data of a printing device other than the printing device for which the user has issued a print instruction can be automatically deleted, the storage capacity of the printing device can be used efficiently and confidential documents can be protected. it can.
