These and other benefits are described throughout the present specification. A further understanding of the nature and advantages of the invention may be realized by reference to the remaining portions of the specification and the attached drawings.
The print management system includes a log server 20, an ID management server 40, a print log integrating server 50, plural “n” pieces of personal computers (PCs) 102-1 to 102-n (generically called 102) and plural “k” pieces of printers 104-1 to 104-k (generically called 104) respectively coupled to a communication network 10 such as an intranet. In this case, each printer 104 is provided with each tag reader 30-1 to 30-k (generically called 30)(in total, “k” pieces of tag readers) that reads information of an IC tag attached to printing paper (merely called paper).
The log server 20 is provided with a mass storage and is provided with a function for storing and managing a log of operation by a user generated in the PC 102 in the storage. For example, when a user X of the PC 102-1 instructs the printer 104-1 to print an electronic document A at time T, a log collection program (not shown) installed in the PC 102-1 collects log information for specifying printing action having relation to the PC 102-1, the user X, the electronic document A, the time T and the printer 104-1 and transmits the log information to the log server 20. The log server 20 stores the received log information. The log server 20 may also store other log information such as who and when output an electronic file B, copied it or deleted it.
In this embodiment, as explained referring to
The tag reader 30 is installed at an ejection slot out of which paper is ejected of each printer 104. The tag reader 30 is provided with a function for reading an IC tag of paper and transmitting the read ID to the ID management server 40 when the paper with the IC tag set on a paper tray of the printer 104 is ejected. The hardware configuration of the tag reader will be described later referring to
The ID management server 40 is provided with a function for managing the ID of the paper read by the tag reader 30. For example, the ID management server stores information that the paper to which the IC tag of ID12345 is attached is printed at the time T by the printer 104-1 (identification information PRT1 of the printer). The configuration of the ID management server 40 will be described later referring to
The print log integrating server 50 is provided with a function for managing information for linking a print log stored in the log server 20 and paper to which an IC tag is attached by communicating with the log server 20 and the ID management server 40. For example, the print log integrating server 50 links the print log that the user X of the PC 102-1 instructed the printer 104-1 to print the electronic document A at the time T and the ID of the paper to which the IC tag of ID12345 is attached. Hereby, it is held and can clearly demonstrated that the paper to which the IC tag of ID12345 is attached is the paper printed by the printer 104-1 instructed to print the electronic document A at the time T by the user X of the PC 102-1. The configuration of the print log integrating server 50 will be described later referring to
As the log server 20 stores a file operation log of a user inside the PC 102, it is provided with no means for specifying a paper medium itself such as which paper is printed. For example, it is enabled by the related art disclosed in JP-A No. 2006-203631, however, in this case, a normal printer is required to be replaced with such a special printer as reads an IC tag from paper and notifies the PC and a log collection program of the PC is required to be replaced with a program that links a print log and received ID of paper. Therefore, the related art is not practical.
According to this embodiment, it can be realized to link and manage paper and a print log without replacing the existing printer already operated and the program for log collection.
In particular, a process until ID is registered in the ID management server 40 is shown. Referring to
First, paper to which an IC tag is attached is set on the paper tray of the printer 104 (S200). In this embodiment, it is not required to be determined which paper is set in the printer by reading every IC tag beforehand. The reason is that the tag reader 30 reads ID when the printed paper is ejected and specifies the paper in a step S210 later.
When a user 200 of the PC 102 instructs to print data of an application program currently operated in a state in which the paper is set on the paper tray (S202), a step S204 for collecting a print log is executed. Operation for collecting a print log is not special itself and can be realized using the existing suitable technique. A characteristic of this embodiment is to collect information at least including the time of printing as a print log as described later referring to
First, the PC 102 executes a log collection program collects a log related to printing (S204-1). The print log includes information such as a name of a file to be printed and printed time. Next, the PC 102 transmits the collected print log to the log server 20 (S204-2). The log server 20 stores the received print log in its storage (S204-3). The contents of the print log will be described later referring to
Next, when the PC 102 transmits a printing job to the printer 104 (S206), the printer 104 receives the printing job and starts printing (S208). When the printing is finished, the paper is ejected (S210). When the paper passes through the ejection slot, the tag reader 30 reads ID of the IC tag of the paper (S212). The tag reader 30 transmits the read ID and identification information for uniquely specifying the tag reader to the ID management server 40 (S214). When reading the IC tag fails and no ID can be acquired, the tag reader transmits ID showing the failure of reading. It is desirable that the ID showing the failure of reading is defined beforehand and is set in the ID management server 40.
Finally, the ID management server 40 registers the received ID information and the tag reader identification information in its storage (S216). A format of the registration will be described later referring to
As shown in
It is recognized based upon the print log information T200 that the printer PRT1 was instructed to print the file “file.doc” in single-sided printing by one copy by a user “aaa” via the PC having an address of “00-13-D3-D2-3E-AD” and the file was printed with A4 paper vertically directed so that two pages are settled in one piece of paper at 12:36:34 on May 11, 2007. Every time a printing process is executed, such print log information is added to the log server 20. In this embodiment, as shown in
As shown in
The tag reader-printer correspondence table T204 is information stored in the ID management server 40 so as to manage link between the tag reader and the printer. This example shows that the tag reader TAG1 is installed in the printer PRT1 (the printer 104-1). It is recognized by using the tag reader-printer correspondence table T402 and the ID information T400-1 together that the paper to which the IC tag of ID12345 is attached was ejected from the printer PTR1.
Though the following is described later referring to
First, the user 202 that operates the print log integrating server 50 specifies ID of paper a print log of which is to be retrieved and a range to be searched (D,D′) required for linking the print log and the ID of the paper (S400). That is, the user instructs the tag reader to read an IC tag attached to the paper and specifies the read ID. Or the user may also specify the ID by coupling the tag reader to the print log integrating server 50 and transferring ID of the IC tag read by the tag reader to the print log integrating server 50. The range to be searched (D,D′) will be described in the following steps S408 and S410.
Next, the print log integrating server 50 retrieves a print log storage 512 with which the print log integrating server 50 is provided and which caches print logs based upon the ID and the range to be searched (D, D′) respectively specified by the user 202 and extracts the corresponding print log. As a result, when the corresponding print log is found, the print log integrating server displays the print log on a display and finishes the process. In the meantime, when the corresponding print log is not found, the following processing steps are executed.
Next, the print log integrating server 50 transmits the ID specified by the user 202 to the ID management server 40 (S404). The ID management server 40 transmits tag read time T corresponding to the received ID and printer identification information to the print log integrating server 50 (S406). For example, when the print log integrating server 50 transmits ID12345 in the step S404, the ID management server 40 collates a list of the ID information T400-1 shown in
Afterward, the print log integrating server 50 transmits a request for exporting a print log to the log server 20 (S408). In the concrete, the print log integrating server requests the log server 20 to export print logs from time T−D to time T+D′ using the tag read time T received in the step S406 and the range to be searched (D,D′) specified by the user 202 in the step S400. When some authentication such as ID, a password and device authentication is demanded in the exportation, authentication is made before the step S408 and a communication session is established between the log server 20 and the print log integrating server 50. As the authentication itself digresses from the subject of the invention, the description is omitted.
The log server 20 retrieves the print logs from the time T−D to the time T+D′ in response to the request in the step S408 and transmits them to the print log integrating server 50 (S410). When a communication session is established before the step S408, the print logs are released after they are transmitted.
The print log integrating server 50 receives the print logs and extracts a candidate of the print log corresponding to the ID of a print specified by the user 202 from the print logs (S412). A method of extracting will be described later referring to
Finally, the print log integrating server 50 displays a list of candidates of the extracted print logs (S414). When no print log exists, the print log integrating server displays a message that no print log exists.
For a transformed example of the above-mentioned example, in place of the user 202 specifying ID of a print, the user 202 sets a largish range to be searched (D,D′) beforehand, the print log integrating server 50 periodically generates ID, executes the processing of the steps S402 to S412, communicates with the log server 20 and the ID management server 40, prepares a list of print log information corresponding to various IDs, and may also cache the list in the print log storage. In this case, there is an advantage that a print log can be immediately extracted in the step S402 even if the print log integrating server 50 does not communicate with the log server 20 or the ID management server 40. However, when the range to be searched (D,D′) is too large and the print log storage overflows, it is desirable that the user 202 erases the cache, sets the range to be searched (D,D′) to a smaller range, and instructs to execute the processing of the steps S402 to S412 again.
For another transformed example, the print log integrating server 50 is not necessarily required to be provided with the print log storage. In this case, the print log integrating server 50 omits the retrieval of a print log in the step S402 and immediately executes the processing of the step S404. In this case, candidates of print logs are not cached in the step S412. According to this example, as no print log storage exists, the mounting cost of the print log integrating server 50 can be reduced.
Next, referring to
As described referring to
A characteristic of this embodiment is that a log corresponding to a print can be found out among a large number of print logs stored in the log server 20 by linking the print and the print log based upon tag read time and the time of printing in the print log without requiring a special log server and a special printer. An example shown in
Further, as printer identification information is also included in the information T500-1 received from the ID management server 40 when the log server 20 can also acquire a name of the printer that prints as a print log, print logs corresponding to the print can be limited more by removing print logs different in printer identification information. In the example shown in
In this example, print ID and print log ID within 60 seconds in the difference between the print log acquired time and the tag reader read time are acquired from the ID management server 40 and the log server 20, respectively, and are held in the management table. There are four print log IDs linked to the print ID 12345 and the time differences among them are 1, 4, 32 and 60 seconds. There is only one print log ID linked to print ID 12346 and the time difference is 3 seconds.
As described above, when the time of printing and printer identification information as a print log can be acquired, a print and a print log can be linked by further using them. Hereby, paper and a print log can be linked without replacing a printer and a log collection program.
When printing fails because of a paper jam, the shortage of paper and others and a print log is stored in the log server 20 by mistake though the printing fails, the log of failed printing which originally has nothing with a print may be linked to the print according to this embodiment. However, an object of the embodiment is not to strictly link a print and a print log in one-to-one correspondence but to extract candidates from a large number of print logs stored in the log server 20 without exception, and the expected object is achieved by collating based upon the time of printing. If the candidates are to be strictly linked, a user has only to compare the actual content of a file and the content of the print using the candidates of print logs.
When printing is delayed because of the replacement of paper and toner and others, no print log really corresponding to a print may be found according to this embodiment. Then, when this embodiment is applied, it is desirable that a largish range to be searched (in units of one day) is specified in consideration of an operational common sense that the delay of printing does not last for a few days. Even if the range to be searched is extended, it is unchanged that a large number of logs stored in the log server 20 can be limited.
Tag readers 701, 711 are installed inside ejection slots of the respective printers. The reason why each tag reader is installed inside each ejection slot is to read an IC tag only once when paper passes through each ejection slot. The reason is also to prevent the IC tag from being repeatedly read by mistake because each tag reader 701, 711 reacts when prints are ejected and are piled on the tray.
Communication cables 702, 712 are cables for transmitting read ID to the ID management server 40. When the tag readers 701, 711 are provided with a radio communication facility and can transmit read ID by radio, the cables 702, 712 are not required.
The tag reader 30 is provided with an input unit 801, CPU 802, RAM 804, a communication interface 806 and a user interface 808. This hardware is coupled via a hub 810.

The ID-print log linking unit 510 calculates link described referring to
The hardware configuration of the print log integrating server 50 is substantially similar to that of the ID management server 40 and is provided with CPU, RAM, ROM, HDD, a communication interface, a user interface, a clock and a hub that couples these units.
In the above-mentioned embodiment, the ID management server 40, the print log integrating server 50 and the log server 20 have the same hardware configuration and are different in a program for realizing their functions. According to a transformed example, each server may be also realized by configuring these three servers or some two servers by common hardware configuration and executing a program for realizing functions of the two or three servers.
This print management system is different from the system shown in
A log server 20 is provided with a function for storing a log of operation by a user in PC 102. In this embodiment, as in the first embodiment, it is premised that the log server 20 can export stored log information to external PC and an external server. Further, it is premised that a print log stored in the log server 20 includes at least the time of printing.
Normal printing paper to which no IC tag is attached is set on a paper tray of a printer 104. Differently from the first embodiment, in this embodiment, ID of paper is managed by writing the ID to print data by the PC 102 in printing.
A print log integrating server 50 is provided with a function for managing information for linking a log stored in the log server 20 and a print.
According to this embodiment, a function for linking paper and a print log can be added to the existing printer and the existing log collection program respectively already operated by installing a program for collecting logs of printing spooling in the PC 102 instead without replacing the printer and the program and without preparing a tag reader and paper to which an IC tag is attached.
Referring to
First, the user 200 of the PC 102 instructs the printer to print data in an application program currently operated (S202). Next, a print log is collected (S204). This processing step is similar to the operation in
A group of steps S900 is a process for writing ID to paper. In normal printing, print data stored in the printing spool device is transmitted to the printer 104, however, in this embodiment, print data is queued in the printing spool device until the writing of the ID to the print data in the step S900-5 is completed.
First, the PC 102 instructs the spooling log collection program (not shown) to collect log information related to printing spooling (S900-1). Collectable log information includes time at which spooling is started, identification information of the PC 102 and a name of a user that logs in. When a format of print data is known, information such as printer identification information and the number of sets can be further also acquired by analyzing the format. Though the following is described later referring to
Next, the PC 102 transmits a request for issuing ID to be written to print data to the ID management server 40 (S900-2). In the concrete, the PC transmits the logs of spooling collected in the step S900-1. Then, the ID management server 40 registers the received log information of printing spooling and issues the ID corresponding to this in one-to-one correspondence (S900-3). The ID management server 40 transmits the issued ID to the PC 102.
The PC 102 writes the received ID to the print data queued in the printing spool device (S900-5). When a format of the print data is known, the PC writes the ID by altering the print data. When the format is unknown, the ID has only to be written after the format of the print data is converted to a format easy to handle such as an image beforehand. As for the conversion of print data to an image, normally known technique has only to be used.
For a method of representing ID, there are a method of overwriting a number of ID to a header, a footer or a background of print data so as to enable a user to read it, a method of converting ID to a bar code and adding it to a corner, digital watermarking technique for embedding information by subtly altering the whole print data so as to be barely perceived by human eyes and tint block watermarking technique for embedding information by adding minute dots to a background of print data.
Processing related to the writing of the ID is finished. Finally, the PC 102 transmits the print data to which the ID is written to the printer 104 as a print job (S204), the printer prints the received print job (S206), and the whole process is completed.
In the step S900-3 shown in
A method of linking a print log and ID of paper in the print log integrating server 50 is the same as the method shown in
When the log server 20 can also acquire the user name and the address of PC as a print log, print logs corresponding to the print can be limited more by excluding print logs which do not coincide with the log of spooling T500-2 received from the ID management server 40. In the example shown in
To limit a print log based upon the log of spooling as described above, the spooling log collection program is required to be designed so that the log of spooling acquired in the step S900-1 shown in
The ID management server 40 is provided with the same function and the same hardware configuration as those of the ID management server 40 shown in
The print log integrating server 50 is also provided with the same function and the same hardware configuration as those shown in
When the time of printing and a log related to printing spooling as a print log can be acquired, a print and the print log can be linked by further using these. As described above, according to this embodiment, paper and a print log can be linked without replacing a printer and a log collection program.
The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense. It will, however, be evident that various modifications and changes may be made thereto without departing from the spirit and scope of the invention as set forth in the claims.
