Abstract

<P>PROBLEM TO BE SOLVED: To improve security in network printing. <P>SOLUTION: This print system is constructed by connecting a client computer PC 100, a server 200, and a printer 300 one another via a network LAN. The PC 100 generates a print job to spool it inside and transmits a user ID to the server 200. The server 200 manages an IP address of the PC 100 and its user ID in association with each other. Under this condition, when the printer 300 notifies the user ID read from an ID card 304 of the user to the server 200, the server 200 instructs output of the print job to the PC 100. When the PC 100 sends the print job, the printer 300 receives the print job and carries out printing. In this way, the print job can be kept in the PC 100 until just before printing, so that security is improved. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a technique for improving security during printing in a printing system in which a large number of users can share a printing apparatus connected to a network.

  Network printing, a printing system in which a printer connected to a so-called network is shared by a number of client computers connected to the network is also widespread. A user can perform printing with an arbitrary printer connected to a network by issuing a print job from a client computer. In network printing, since a printer is shared by a plurality of users, there is a risk that another person may carry his / her printed matter or be seen by others. In order to avoid such an adverse effect, various technologies for guaranteeing that only a person who has an authority to receive a printed material can receive the printed material, that is, a technology related to so-called confidential printing, have been proposed.

  For example, Patent Document 1 discloses a technique in which a personal computer is assigned a personal identification number and a print job is sent to a printer, and then, when the personal identification number is input by operating the printer panel, the transmitted print job is executed. Is disclosed. In the technique disclosed in Patent Document 2, a virtual bin specific to a user is set for each printer, and the user sends a print job to the bin. When the user operates the printer panel and inputs a bin number and a password, a print job addressed to the corresponding bin is executed. In the technique disclosed in Patent Literature 3, when a print job is transmitted from a client to a host computer, the host computer issues a job number to the print job. When the user operates the printer panel and inputs a job number, the printer acquires a print job from the host computer and executes it.

Japanese Patent Laid-Open No. 11-353137 JP 2000-293338 A Japanese Patent Laid-Open No. 10-235974

  However, the conventional technology related to confidential printing lacked security in the following points. In other words, all of the prior arts require that a print job be issued from a client computer. Therefore, for example, a malicious third party may illegally output a printed matter or view the contents of a print job by attempting unauthorized access to a host computer or printer. The present invention has been made in view of the above problems, and an object thereof is to further improve security in network printing.

  The present invention can be configured as a printing system that includes a print job generation device, a management device, and a printing device, and that performs printing by transmitting a print job from the print job generation device to the printing device via a network. As the print job generation apparatus, for example, a personal computer in which various application programs are installed can be used. For example, the management apparatus may be an independent server connected to a network, or may be incorporated into the printing apparatus in hardware or software.

  The print job generation apparatus inputs a print command by a user operation, and generates a print job according to the print command. This print job is temporarily held in the print job generation apparatus, and job specifying information for specifying the print job is transmitted to the management apparatus. The management apparatus manages the received job identification information in association with communication destination identification information required for communication with the print job generation apparatus.

  The printing apparatus has an operation unit for a user to perform an operation for inputting job specifying information. When the user operates the operation unit to input job specifying information, the printing apparatus notifies the management apparatus of the job specifying information. The management apparatus searches for communication destination identification information corresponding to the notified job identification information, and transmits an instruction for sending a print job to the print job generation apparatus using the communication destination identification information. In response to this instruction, the print job generation apparatus transmits the held print job to the printing apparatus. The printing apparatus receives the print job and performs printing.

  According to the printing system of the present invention, the print job is held in the print job generation apparatus until a print job transmission instruction is received. Accordingly, it is possible to ensure the security of the print job at the same level as the state where the user is creating a print document or the like with the print job generation apparatus. Further, since the transmission instruction is triggered by an operation on the printing apparatus by the user, that is, input of job specifying information to the printing apparatus, printing is performed in a situation where it is guaranteed that the user is in the vicinity of the printing apparatus. Therefore, it is possible to suppress the possibility that a third party has the printed matter or sees the contents.

  In addition, the printing system of the present invention has an advantage that the configuration of the printing apparatus is simplified. For example, since the print job is held in the print job generation apparatus until immediately before printing, it is not necessary to prepare a storage device for spooling the print job such as a hard disk in the printing apparatus, and the structure can be simplified. Cost reduction can be achieved. Since it is not necessary to provide a high-performance spooler in the printing apparatus, the firmware of the printing apparatus can be simplified. In addition, even if a storage device such as a hard disk is provided in the printing apparatus, since the print job spooled there can be suppressed, the storage capacity is compressed by an unprocessed print job, It is possible to suppress the risk of hindering processing during printing.

  The job specifying information may be manually input by the user to the printing apparatus, or may be read by the printing apparatus from a portable medium. In the latter mode, the job specifying information can be easily input and the user does not need to store the job specifying information, so that convenience is improved. As the portable medium, for example, a magnetic card, an IC card equipped with an IC chip, a USB storage, or the like can be used. The printing apparatus may display the job specifying information input by any method on the panel. As described later, various types of information can be used as the job specifying information. In the present invention, only one of these types may be applicable, or a plurality of types of information may be used in combination. In the latter case, for convenience, for example, a menu for selecting the type of job specifying information may be displayed on the panel of the printing apparatus.

  In the present invention, the job specifying information can be, for example, information that can specify at least one of a user and a print job generating apparatus. The former includes a user ID and a user name. The latter includes an identification number assigned to the print job generation apparatus, a serial number, and address information unique to the apparatus. Since these pieces of information can be used fixedly irrespective of the print job, they are suitable for the use of the portable medium described above. The job specifying information may be information dependent on the print job. Examples of such information include a job name and a job number uniquely assigned to a print job. In the case where a printed matter can be specified for each page of a document, the page number of the document may be used as job specifying information. In addition, print deadline information set for a print job, or a print reminder number or message issued to prompt the user to print when the preset print deadline is approached can be used as the job specifying information.

  In the present invention, the communication destination specifying information includes, for example, an IP address. The communication destination specifying information can be transmitted in association with the job specifying information from the print job generating apparatus. As another aspect, for example, when the job specifying information and the communication destination specifying information are information that is not unique to the print job, the correspondence between them may be registered in the management apparatus in advance. In this case, the management apparatus can manage the job identification information received from the print job generation apparatus and the communication destination identification information in association with each other by referring to the registered content.

  When a plurality of printing apparatuses are provided in the printing system, each printing apparatus preferably transmits specific information for identifying itself when notifying the management apparatus of job specifying information. This specific information includes, for example, an identification number or an address assigned to the printing apparatus. In addition, the management apparatus preferably designates the print apparatus that is the destination of the print job based on the specific information to the print job generation apparatus. By doing so, even when a plurality of printing apparatuses are provided, the printing apparatus that is the output destination can be designated easily and without error.

  In the present invention, the print job may be directly transmitted from the print job generation apparatus to the printing apparatus, or may be relayed by the management apparatus. According to the former, there is an advantage that the load on the management apparatus when a print job is sent is reduced. According to the latter, there is no need to designate a printing apparatus as an output destination for the print job generation apparatus, so that there is an advantage that the contents of a print job transmission instruction can be simplified.

  The present invention can be configured in various ways. For example, the present invention may be configured as a sub-combination of the above-described printing system, that is, each device of a print job generation device, a printing device, and a management device. Further, a printing method using a printing system using a print job issuing device, a printing device, and a management device may be configured. In the printing system, each of the print job issuing device, the printing device, and the management device may be configured as a computer program for realizing the functions described above and a computer-readable recording medium that records the computer program. it can. Recording media include flexible disks, CD-ROMs, magneto-optical disks, IC cards, ROM cartridges, punch cards, printed matter printed with codes such as bar codes, computer internal storage devices (memory such as RAM and ROM), and Various media that can be read by a computer, such as an external storage device, can be used.

Embodiments of the present invention will be described in the following order.
A. System configuration:
B. Function block:
C. Confidential printing process:
D. Variation:

A. System configuration:
FIG. 1 is an explanatory diagram showing a schematic configuration of a printing system as an embodiment. In this printing system, confidential printing can be performed using the user ID. In the present embodiment, it is assumed that an ID card 304, that is, a magnetic card recording a user ID is distributed to each user who uses this printing system.

  This printing system is configured by connecting a client computer 100, a server 200, and a printer 300 via a local area network LAN. The client computer 100 and the printer 300 are not limited to the example shown in the figure, and an arbitrary number of them can be connected.

  A client computer 100 (hereinafter simply referred to as “PC”) is a general-purpose personal computer having a network communication function, and generates a print job based on document data created using various applications. The printer 300 executes a print job sent from the PC 100. The printer 300 is provided with a slot 302 for reading a user ID from the ID card 304. The server 200 corresponds to a management device according to the present invention, controls operations of the PC 100 and the printer 300, and realizes confidential printing between the two.

  Confidential printing is performed according to the following procedure. The user logs in to the PC 100, creates print data with an application, and inputs a print command. The PC 100 generates a print job according to the print command, spools it inside, and transmits the job specifying information and its own IP address, that is, the client IP, to the server 200 (arrow A in the figure). As job specifying information, a user ID, that is, a user ID is used. The server 200 manages the job identification information and the client IP in association with each other. Hereinafter, this managed information is referred to as print reservation information.

  Next, the user passes the ID card 304 into the slot 302 of the printer 300 to be printed. The printer 300 reads the user ID from the ID card 304 and notifies the server 200 together with its own IP address, that is, the printer IP (arrow B).

  The server 200 searches the managed print reservation information, specifies the output destination printer IP to the PC 100 corresponding to the user ID received from the printer 300, and transmits a print job transmission instruction (arrow C). ). When the PC 100 sends a print job in response to this instruction, the printer 300 receives and executes this print job (arrow D).

B. Function block:
FIG. 2 is an explanatory diagram showing functional blocks for realizing the printing system. Each functional block in the drawing is constructed by software by installing a program for realizing each function in the PC 100, the server 200, and the printer 300. With respect to the printer 300, these functional blocks are realized by firmware executed by a CPU in a control unit mounted therein. At least a part of these functional blocks may be configured in hardware.

  A functional block of the PC 100 will be described. The communication unit 130 controls communication with other devices via the network LAN. For example, a NIC (Network Interface Card) driver and various protocols correspond to the communication unit 130.

  The application 110 runs on the operating system of the PC 100 and generates document data for printing. The printer driver 140 receives document data from the application 110 and generates a print job suitable for the printer 300. The spooler 150 has a function of holding and managing this print job.

  In this embodiment, a confidential printing agent 120 is prepared in addition to these functions. The confidential printing agent 120 is a kind of application running on the operating system or software installed as a function of the operating system. Each block provided in the confidential printing agent 120 has the following functions.

  After the print job is generated according to the print command from the user, the job specification information transmission unit 122 controls the spooler 150 to suspend the print job transmission. Then, the job specification information and the IP address of the PC 100 are transmitted to the server 200. In the present embodiment, the job identification information uses a user ID input when the user logs in. When a print job transmission instruction is input from the server 200, the job transmission control unit 124 controls the spooler 150 to transmit the print job to the printer 300 designated by the transmission instruction.

  Next, functional blocks of the server 200 will be described. The communication unit 220 controls communication via the network. Upon receiving job specification information from the PC 100, the job management unit 240 associates this job specification information with the IP address of the PC 100 and manages it as print reservation information. The contents of the print reservation information are illustrated in a table format in the figure. In this example, it can be seen that the users “aaa” and “bbb” have reserved print jobs. It can be seen that the IP addresses (“PC IP” in the figure) of the PC 100 that issued the print job are “pca”, “pcb”, and “pcc”, respectively. The reason why the two types of IP addresses “pca” and “pcc” are associated with the user “aaa” is that this user has issued a print job from a different client computer. Unlike the example shown in the figure, “Printer IP” is still blank when job specifying information is received from the PC 100.

  The job identification information receiving unit 210 receives job identification information from the printer 300 when executing printing. The job sending instruction unit 230 refers to the job management unit 240 and searches for print reservation information corresponding to the job specifying information. When the print reservation information is found, the IP address of the printer 300 that transmitted the job specification information is recorded in “Printer IP”, and the print job is sent to “PC IP” designated by the print reservation information. Send instructions. When a plurality of print reservation information having different “PC IP” is found, a transmission instruction is transmitted to each IP address. In any case, the transmission instruction includes the IP address of the printer 300 as information specifying the transmission destination of the print job.

  Recording “Printer IP” prior to transmission of the transmission instruction indicates that the transmission instruction has been completed for the print reservation information, and facilitates handling when there is a problem in the print job transmission process. Because. In the present embodiment, the recording of “Printer IP” can be omitted.

  Finally, functional blocks of the printer 300 will be described. The communication unit 310 controls communication via the network. The card reading unit 340 controls the slot 302 (see FIG. 1) to read the user ID from the card. The job specific information notifying unit 330 transmits the user ID to the server 200 as job specific information. The printing unit 320 corresponds to a so-called print engine, and executes a print job received from the PC 100.

C. Confidential printing process:
FIG. 3 is a flowchart of confidential printing processing. The process executed by the PC 100 on the left side, the process executed by the server 200 on the center, and the process executed by the printer 300 are shown on the right side, respectively. This process is executed in a state in which after the user inputs a user ID to the PC 100 and logs in, the document data is created by the application and the preparation for printing is completed. The confidential printing process is roughly divided into a print reservation process (a process above the one-dot chain line in the figure) and a print execution process (a process below the one-dot chain line).

  When the user inputs a print command (step S10), the PC 100 generates a print job from the document data created by the application and spools it (step S12). Then, the user ID and “PC IP” are transmitted to the server 200 (step S14). As described above, the server 200 registers these pieces of information as print reservation information in the job management unit (step S20). The print reservation process has been described above.

  Next, the user passes the ID card 304 into the slot 302 of the printer 300 where the printed material is to be output. The processing of the printer 300 is started with this operation as a trigger, and reads the user ID from the ID card 304 (step S30). Then, this user ID and its own IP address are transmitted to the server 200 (step S32).

  When the server 200 receives the information from the printer 300, the server 200 searches the print management information corresponding to the received user ID from the job management unit (step S22). Then, a print job transmission instruction including the IP address of the printer is transmitted to “PC IP” designated by the print reservation information (step S24).

  The PC 100 sends a print job in response to this send instruction (step S16). The printer 300 receives and executes this print job (step S34). The print execution process has been described above.

  According to the embodiment described above, the print job is held in the PC 100 until printing is performed. Accordingly, it is possible to ensure the same level of security as when the document data is created by the application.

  In addition, since the user executes printing by passing the ID card 304 through the slot 302, it is guaranteed that the user is in the vicinity of the printer 300 at the time of printing. It is possible to suppress the possibility of

  Further, the printing system according to the embodiment has an advantage that the output destination can be designated easily and without error by a method of operating the printer 300.

  Further, the printing system of the embodiment has an advantage that the configuration of the printer 300 is simplified. For example, since the print job is held in the PC 100 until immediately before printing, it is not necessary to prepare a hard disk in the printer 300, and the structure can be simplified and the cost can be reduced. Since it is not necessary to provide a high-performance spooler in the printer 300, the firmware can be simplified. Even if the printer 300 is provided with a storage device such as a hard disk, the amount of print jobs spooled there can be reduced, so that the storage capacity is compressed by unprocessed print jobs. Therefore, it is possible to suppress the possibility of hindering processing during printing.

D. Variation:
(1) FIG. 4 is an explanatory diagram showing a schematic configuration of a printing system as a first modification. In this printing system, it is assumed that a client computer used by each user is fixed in advance.

  Unlike the embodiment, the PC 100A issues a print job, spools it inside, and then transmits only the job specifying information to the server 200A (arrow A1). The server 200A includes an address registration table 242 in addition to the functional blocks described in the embodiment (see FIG. 2). The address registration table 242 is a table in which the user ID and the IP address of the client computer are stored in association with each other. The server 200 </ b> A can indirectly associate the job specifying information with “PC IP” by referring to the address registration table 242.

  When executing printing, the same processing as in the embodiment can be applied. However, as shown below, the server 200A may relay the print job between the PC 100A and the printer 300. In this process, when the server 200A receives the job specifying information and the IP address of the printer from the printer 300 (arrow B), the server 200A searches for print reservation information and transmits a print job transmission instruction to the PC 100A as in the embodiment. (Arrow C1). However, the IP address of the printer 300 is not included in this transmission instruction.

  When receiving the transmission instruction, the PC 100A transmits a print job to the server 200A (arrow D1). The server 200A relays this print job to the printer 300 (arrow D2). By doing so, the transmission destination of the print job by the PC 100A can be fixed, so that the processing of the PC 100A at the time of print job transmission can be simplified. Further, the IP address of the printer 300 can be kept secret from the user, and there is an advantage that unauthorized access to the printer 300 can be suppressed.

  Also with the printing system of the first modification, confidential printing can be realized as in the embodiment. The process at the time of printing in the first modification, that is, the process in which the server 200A relays the print job is also applicable to the embodiment.

(2) FIG. 5 is an explanatory diagram showing a schematic configuration of a printing system as a second modification. In the second modification, job specific information unique to a print job is used. In this example, the job identification information is generated by combining the user ID and the serial number. The printer 300 is provided with a touch panel 306 as an interface for inputting job specifying information.

  In the second modification, when the print job is generated and spooled according to the print command, the PC 100B generates job specifying information including a combination of a user ID and a serial number, and the server 200B together with its own IP address. Send to. The server 200B manages this information as print reservation information. The procedure at the time of printing is the same as that in the embodiment except that the contents of the input job specifying information are different.

  FIG. 6 is a flowchart of the print execution process in the second modification. This is a process after the print reservation process (see FIG. 3) is completed, and the process of the server 200B is shown on the left side and the process of the printer 300B is shown on the right side.

  The printer 300B displays a menu for selecting an input method of job specifying information on the touch panel 306, and inputs a selection instruction (step S40). An example menu is shown in the figure. In this example, two methods can be selected: a method of inputting a user ID and selecting a print job (menu 1), and a method of directly inputting job identification information (menu 2). On the right side of the menu, a numeric keypad for inputting a selection instruction is displayed.

  Many more menus may be prepared. For example, in a printing system that permits the combined use of various types of job identification information such as an arbitrary job name in addition to a user ID, a menu for selecting the type of job identification information may be provided.

  If the printer 300B determines that the user ID is not required (step S41), the printer 300B inputs the job specifying information by operating the numeric keypad (step S42), and transmits it to the server 200B (step S46). The case where the menu 2 exemplified in step S40 is selected corresponds to this process.

  On the other hand, if it is determined that the user ID needs to be input (step S41), the printer reads the user ID from the slot 302 (step S43) and transmits it to the server 200B (step S44).

  The server 200B searches the job management unit (step S22A), extracts print reservation information including the user ID in the job specifying information, creates a job list, and sends it to the printer 300B (step S23A). The printer 300B displays this list on the touch panel 306 and inputs a print job selection instruction (step S45). The job list display example is shown in the figure. In this example, print jobs whose job identification information is configured by user ID “aaa” + serial number are listed. The user can select a print job to be executed using the numeric keypad. The printer transmits job specifying information to the server 200B according to the selection result of the user (step S46).

  The following procedure is the same as in the example. That is, the server 200B issues a print job transmission instruction to the PC 100B based on the job specifying information from the printer 300B (step S24A). When the PC 100B transmits a print job in response to the transmission instruction, the printer 300B receives this and executes printing (step S47).

  Also with the printing system of the second modification, confidential printing can be realized as in the embodiment. In the second modification, there is an advantage that whether or not printing can be executed can be controlled in units of print jobs. In the second modified example, job specifying information can be directly input by the touch panel 306. For example, this printing system can be used for providing a document to another person by notifying the other person of the job specifying information. is there.

(3) The management device is not necessarily provided separately from the printer 300 as in the server 200, and may be incorporated in any printer on the network LAN. For example, a board incorporating a circuit that realizes the function of the server 200 may be incorporated in a printer by attaching it to a printer. In addition, firmware that implements the function of the server 200 may be installed in software by installing it in a printer.

  As mentioned above, although the various Example of this invention was described, it cannot be overemphasized that this invention is not limited to these Examples, and can take a various structure in the range which does not deviate from the meaning.
