Technical Field
The present invention relates to a printing system, and more particularly, to a printing system capable of acquiring a print count of a printer.

At present, there are many printer renters who rent the printers to the enterprises and pay the fees according to the number of the printers, for example, count how many times each printer prints in black and white, a4 paper, in color, a4 paper, etc. each month. In addition to these printer renters, some enterprises are equipped with a large number of printers for daily office work, but these enterprises also need to know the print count of each printer, so as to count the consumables of the printers and purchase and replenish the consumables in time.
In order to facilitate counting of the number of prints of a printer, some printer brands are provided with printer management software capable of managing own printers, and counting of the number of prints can be assisted. In addition, there are also small brands of printers that do not provide printer management software, making statistics of print counts more difficult.
Therefore, it is difficult for printer renters and business organizations to manage the print count in a unified manner, and each printer has a MIB storing its own information, which is specified by the printer standard, and the total print count of the printer is stored in the MIB.
Under the environment, some printer renters or enterprise organizations adopt cloud printing platforms, and users can upload printing tasks through the cloud server, so that the printing tasks are forwarded to the printers by the cloud server for printing. In this way, the print quantity count of the printer can be indirectly counted according to the print tasks by counting the print tasks uploaded by the user. However, this method cannot exclude some users from printing offline or going to the back door, and print with the printer directly by bypassing the cloud server, so that the count of the number of prints counted by the cloud server does not match the actual number of prints of the printer.

< example >
Fig. 1 is a block diagram of the configuration of a printing system in the embodiment of the present invention.
As shown in fig. 1, the printing system 100 includes N printers 101, one management server 102, and a communication network 103.
In this embodiment, the management server 102 is connected to each printer 101 through a communication network 103.
The printer 101 is used to print a file to be printed by a user. The file to be printed may be a file which is input to the printer 101 by a user from a line, or a file which is uploaded by the user through the management server 102.
As shown in fig. 1, in the printing system 100, the device models of some printers 101 are the same, for example, the device models of the printers 101-1 and 101-2 are both type I, and there are some printers of different brands and different models, for example, the device model of the printer 101-3 is type II, and the device model of the printer 101-N is type X.
Each printer 101 has a print information storage section 11 and a printing section 12. Specifically, the method comprises the following steps:
the print information storage unit 11 is a MIB of a printer standard, and stores various kinds of printer information of the printer and information storage addresses respectively pointing to the printer information, and these printer information are stored in the MIB in a tree form. In this embodiment, the data stored in the MIB is of the following data type: integer type (Integer), text type (OCTER STRING), IP address (IPAddress), non-negative Integer (Counter), time Counter (TimeTimks), and OBJECT IDENTIFIER (OBJECT IDENTIFIER).
The object identifier (OID key) is an information storage address, and is used to identify and locate each piece of printer information.
In this embodiment, the printer information stored in the printer information storage units of the different printers at least includes the device model of the printer, the color support parameter, the printer paper cassette size parameter, the print status parameter, and the print quantity count.
According to the RFC1759 standard, printers of various brands and models need to store device models, color support parameters, printer paper box size parameters, and printing state parameters according to predetermined OID key values. If the color support parameter needs to be stored in the MIB node (node name prtmarkerprocessancolorants) with OID key value "1.3.6.1.2.1.43.10.2.1.6.1.1", the value of the parameter is 1, which indicates that the printer is a monochrome machine, and the value is 4, which indicates that the printer is a color machine.
In the printer, the size parameter of the printer paper cassette is stored by three parameters, specifically, a unit of paper length (prtOutPutDimUnit), and a corresponding OID key value is "1.3.6.1.2.1.43.9.2.1.14.1.1"; the maximum length (prtoutputmaxdimedfeed) of the paper in the same direction as the paper feeding direction corresponds to an OID key value of "1.3.6.1.2.1.43.9.2.1.15.1.1"; and the maximum length of the sheet in the direction perpendicular to the sheet feeding direction (prtOutPutMaxDimXFeedDir), the corresponding OID key value is "1.3.6.1.2.1.43.9.2.1.16.1.1". By combining these three parameters, the size of the printer paper cassette can be known.
In addition, the device model includes the brand and model information of the printer 101, and a print status parameter (hrprintertstatus) indicates whether the printer 101 is out of order, whether to print an intermediate print status, and both are stored in the MIB base as specified in the RFC1759 standard.
In contrast, since the number of the prints is set by the manufacturer of each brand, and the OID key values corresponding to the print counts of the printers of different brands and different models may be different, the management server 102 of this embodiment needs to determine the OID key values corresponding to the number of the prints from the printers 101 of various models.
The printing unit 12 is configured to execute the print detection task sent by the management server 102 and print the print detection file in the print detection task, and the printing unit 12 also executes the to-be-printed task sent by the user and prints the to-be-printed file in the to-be-printed task.
Fig. 2 is a block diagram of a management server in the embodiment of the present invention.
As shown in fig. 2, the management server 102 includes a print parameter address storage unit 21, a detection file storage unit 22, a print volume address storage unit 23, a model information acquisition unit 24, a first connection determination unit 25, a monitor acquisition unit 26, a print information detection control unit 27, a print parameter acquisition unit 28, a print job generation unit 29, a print control unit 30, a print state monitoring unit 31, an abnormality information output unit 32, a comparison determination unit 33, a print volume count acquisition unit 34, a management-side communication unit 35, and a management-side control unit 36 for controlling the above-described units.
The print parameter address storage section 21 stores print parameter addresses storing color support parameters and printer paper cassette size parameters and status parameter addresses of print status parameters in the print information storage section 11, which are known from the RFC1759 standard. The printing parameter address is the OID key value corresponding to the above color support parameter and the printer paper box size parameter, and the state parameter address is the OID key value corresponding to the above printing state parameter.
The detection file storage unit 22 stores a preset detection file for generating a print detection job.
The print quantity address storage unit 23 is configured to store a print quantity address (OID key) corresponding to a print quantity count in the printer 101 after the comparison determination unit 33 determines the print quantity address (OID key) corresponding to the print quantity count.
FIG. 3 is one of the tables of contents stored in the print size address storage section in the embodiment of the present invention.
As shown in fig. 3, the print quantity address storage unit 23 stores the device model 231 of the printer 101, the corresponding print quantity address 232, and the print parameter 233 corresponding to each print quantity address. It can be seen that since the I-type printer is a monochrome printer and only supports printing a4 paper, the print quantity address storage unit 23 stores only the print quantity count addresses corresponding to the I-type printer with the print parameters "monochrome", "a 4" and "monochrome a 4", and similarly, the III-type printer is a color printer and supports both A3 and a4, and stores only the print quantity count addresses corresponding to the print parameters "monochrome", "A3", "a 4", "monochrome A3" and "monochrome a 4". (the print count address of "color A3" and other color paper type combinations is not shown in FIG. 3.)
The model information acquisition section 24 is configured to directly acquire the device model of the printer based on the SNMP protocol when the management-side communication section 36 is communicatively connected to the printer 101.
The primary connection judging section 25 is configured to judge whether or not there is an apparatus model identical to the model to be judged in the print volume address storing section 23, based on the apparatus model acquired by the signal information acquiring section 24.
If the first connection determination unit determines that the connection is established, the first connection determination unit 25 further determines that the management-side communication unit and the printer are not initially connected, and may subsequently control the printer to perform printing by the print control unit 30 or acquire the number of prints of the printer by the number-of-prints acquisition unit 34.
If the first connection determination section determines that the connection is not established, the first connection determination section 25 further determines that the management-side communication section and the printer are in communication connection for the first time, and the monitor acquisition section 26, the print information detection control section 27, and the comparison determination section 33 operate to detect the print count address in the printer.
Taking the printer 101-3 and the device model "type II" as an example, as can be seen from fig. 3, the print quantity address storage unit 23 does not store corresponding model information, so the initial connection determination unit 25 determines that the printer 101-3 is an unknown model, and then detects the print quantity address of the printer 101-3.
The monitor acquiring unit 26 is configured to acquire printer information of the printer from the print information storage unit 11 as the information to be compared.
Since the number of prints is set by the vendor of each brand and is stored in the vendor private subtree of the MIB database, in this embodiment, the monitoring obtaining part 26 first obtains the vendor private subtree root node according to the OID key value ". 1.3.6.1.2.1.1.2.0" of the "vendor private subtree root node information" defined in the RFC1759 standard, and obtains all OID key values under the vendor private subtree according to the vendor private subtree root node. Further, the monitoring obtaining part 26 may also screen out, from all the OID key values under the private subtree of the manufacturer, corresponding OID key values of which the types are integer types and non-negative integer types as screened OID key values. And finally, acquiring corresponding printer information from the printing information storage part 11 according to the screened OID key values to serve as the information to be compared.
The print information detection control unit 27 controls the operations of the components for print detection, specifically, controls the operations of the print parameter acquisition unit 28, the print job generation unit 29, the print control unit 30, the print status monitoring unit 31, and the abnormality information output unit 32.
When the management-side communication unit 35 is first brought into communication with the printer 101, the print information detection control unit 27 controls the print parameter acquisition unit 28 to acquire the print parameters from the printer information storage unit 11, controls the print detection job generation unit 29 to generate a plurality of print detection jobs each including different print parameters based on the acquired print parameters and the stored detection file, further controls the print control unit 30 to sequentially send the plurality of print detection jobs to the printer 101 to allow the printing unit 12 to perform a plurality of prints, and controls the print state monitoring unit 31 to monitor the state of the printer 101 during the plurality of prints and controls the abnormal information output unit 32 to output abnormal information when an abnormality is monitored. Specifically, the method comprises the following steps:
since the printer 101 does not directly store the printing parameters, the printing parameter acquiring unit 28 needs to determine the printing parameters supported by the printer based on the color support parameters and the printer paper cassette size parameters stored in the printer information storage unit 11 when acquiring the printing parameters.
FIG. 4 is a block diagram showing the configuration of a print parameter acquiring section in the embodiment of the present invention.
In the present embodiment, the printing parameters include a printing support color and a printing support paper type, and as shown in fig. 4, the printing parameter acquiring unit 28 specifically includes a paper size storage unit 281, a printing color acquiring unit 282, and a printing paper type acquiring unit 283.
The paper size storage unit 281 stores in advance standard paper sizes of a plurality of standard print paper types, for example, 297mm by 420mm for the A3 paper type and 210mm by 297mm for the a4 paper type.
The print color acquisition unit 282 acquires, from the print information storage section 11, a color support parameter indicating the color characteristic of the printer based on the print parameter address "1.3.6.1.2.1.43.10.2.1.6.1.1" stored in the print parameter address storage section 21. When the value of the color support parameter is 1, the print support color acquired by the print color acquisition unit 282 is black and white; when the value of the color support parameter is 4, the print support color acquired by the print color acquisition unit 282 is both black-and-white and color.
The print paper type acquisition unit 283 first acquires three print cassette size parameters of a unit of paper length, a maximum length of paper in the same direction as the paper feed direction, and a maximum length of paper in a direction perpendicular to the paper feed direction from the print information storage section 11 based on the print parameter address stored in the print parameter address storage section 21. Next, the size parameters of the printing paper cassette are compared with the sizes of the standard papers in the paper size storage unit 281, so as to obtain the paper types that can be supported by the printer.
For example, assuming that the printer 101-3 has a paper length unit of mm, a maximum length of paper in the same direction as the paper feeding direction of 432, and a maximum length of paper in a direction perpendicular to the paper feeding direction of 300, 432mm >420mm >297mm and 300mm >297mm >210mm, the print supporting paper types corresponding to the printer 101-3 are A3 and a 4.
When generating the print detection job, the print job generating unit 29 differently combines the print support color and the print support paper type to form a combination parameter, and generates the print detection job for printing the detection file based on the different combination parameters.
FIG. 5 is a schematic diagram of a print test job in an embodiment of the present invention.
Taking the example where the print supporting colors are color and black and white and the print supporting paper types are a4 and A3, the combination parameters formed by combining the print supporting colors and the print supporting paper types are "color a 4", "color A3", "black and white a 4", and "black and white A3", as shown in fig. 5, the print job generating section 29 generates four print job candidates, and each print job 291 corresponds to a different combination parameter.
The print control unit 30 controls the printing unit 12 of the printer 101 to perform printing. In the present embodiment, the print control section 30 is a print driver corresponding to the brand of the printer 101, which is installed in advance in the management server 102.
The printing state monitoring section 33 monitors the printing state parameters in the printer information storage section 12 in real time based on the state parameter addresses stored in the printing parameter address storage section 21. In this embodiment, the range of values of the printing state parameter is as follows: 1, failure; 2, unknown fault; 3, idling; and 4, printing.
The status of the printer can be confirmed by other parts by the print status parameters acquired by the print status monitoring unit 33. Specifically, the method comprises the following steps:
when controlling the print control unit 30 to perform printing, the print information detection control unit 27 first checks whether the print status parameter detected by the print status monitoring unit 33 is 3, and requests printing when no trouble or no print job is ensured in the printer.
In addition, the operation of acquiring the information to be compared by the monitoring acquisition unit 26 before and after the completion of the print job is also performed according to the print state parameter, and after the print information detection control unit controls the print job generation unit 29 to generate the job to be printed, the monitoring acquisition unit 26 acquires the information to be compared once when the print state parameter is 3; next, when the printing control portion 30 prints a print detection task, the printing status parameter has a variation 3- >4- >3, which indicates that the printing is normally completed, and at this time, the monitor acquiring portion 26 acquires the comparison waiting information again. By analogy, the monitoring acquisition unit 26 acquires the information to be compared before and after printing for each print test task.
FIG. 6 is a diagram illustrating information to be compared according to an embodiment of the present invention.
As shown in fig. 6, taking the printer 101-3 as an example of printing the four print detection jobs in fig. 5, the monitor acquiring unit 26 acquires 5 pieces of information to be compared finally, and each piece of information to be compared 261 is acquired according to the same information storage address, and includes printer information 2611 corresponding to the print quantity count of each print parameter, printer information 2612 corresponding to the number of print jobs, and other printer information 2613. The number of print jobs is a parameter for counting the number of times of executing print jobs (print detection jobs) in the printer.
If the printing state monitoring section 33 monitors that the printing state parameter becomes 1 or 2, indicating that a trouble such as paper jam, ink shortage, etc. has occurred in the printer, the abnormality information output section 34 sends printing abnormality information to the user to allow the user to remove the trouble. The print information detection control section 27 controls each section to terminate printing of a plurality of print detection jobs at the same time.
When a trouble occurs, since the printer information in the printer also changes, when the user removes the trouble, the print information detection control section 27 controls the print job generation section 29 to regenerate a plurality of print detection jobs and controls the monitor acquisition section 26 to resume the acquisition of the printer information, thereby performing print detection from each section under the head re-control.
The comparison determination unit 33 is configured to compare the information to be compared acquired by the monitoring acquisition unit 26, determine printer information corresponding to a change in the print parameter in each print test job before and after each print test job, and further obtain print quantity counting information and corresponding print quantity counting addresses corresponding to different print parameters.
FIG. 7 is a block diagram showing the structure of the alignment judgment section in the embodiment of the present invention.
As shown in fig. 7, the comparison determination unit 33 includes a print count information filtering unit 331, a print parameter comparison unit 332, and a print count address correspondence unit 333.
The print count information screening unit 331 is configured to screen, as print count information, printer information that has a predetermined change before and after each print detection task is completed, based on the information to be compared.
In this embodiment, the predetermined change is such that the change in the value of the printer information coincides with the number of times of printing the file for print detection in the print detection job.
Taking fig. 5 and 6 as an example, after the printing detection task 2 is printed, the print quantity counting information screening unit 331 compares the information to be compared 2 with the information to be compared 3, and it can be seen that, in each piece of printer information, the value of the printer information corresponding to the printing parameters "black and white", "a 4" and "black and white a 4" and the value of the printer information corresponding to the number of printing jobs are increased by 1, that is, a predetermined change occurs; after printing the print test job 4, the print quantity information filtering unit 331 compares the information to be compared 4 with the information to be compared 5, and it can be seen that, in each piece of printer information, the value of the corresponding three pieces of printer information, i.e., "black and white", "A3", and "black and white A3", is added by 2. Similarly, the print quantity information filtering unit 331 performs the same processing for the print test job 1 and the print test job 3, and details thereof are not repeated (the printer information corresponding to the print quantity counts of "color a 4" and "color A3" is not shown in fig. 6).
Through the comparison process, the print count information filtering unit 331 can filter the print count information, and for the number of times of the print job, which may generate a corresponding changed interference item during the execution of the print job, the interference item can be removed by determining whether the change of the value corresponds to the number of times of printing.
The printing parameter comparing unit 332 is configured to compare the printing parameters corresponding to each print quantity information according to the printing parameters and the corresponding print quantity information included in each print detection task.
Based on the comparison process, the print parameter comparison unit 332 further determines the print quantity counting information that changes in each print detection task, and compares the print parameters corresponding to each print quantity counting information. Specifically, if the value is increased by 1 after the execution of the print test job 2 and increased by 2 after the execution of the print test job 4, and the remaining value is not changed, the print parameter corresponding to the print count information may be determined as "black and white", and similarly, the print count information corresponding to the print parameters such as "color", "A3", and "a 4" may be determined. If the value is increased by 1 only after the execution of the print test job 2, and is not changed in other cases, the print parameter "black-and-white a 4" corresponding to the print count information can be determined, and similarly, the print count information corresponding to the composite print parameter such as "black-and-white A3", "color a 4", or "color A3" can be determined.
The print quantity counting address corresponding unit 333 is configured to use an information storage address corresponding to the print quantity counting information as a print quantity counting address and correspond to a corresponding print parameter.
FIG. 8 is a second table of contents stored in the print size address storage unit according to the embodiment of the present invention.
Once the print quantity address correspondence unit 333 completes the correspondence, the print quantity address storage unit 23 stores the print quantity address and the corresponding print parameters in correspondence with the device model of the printer 101. As shown in fig. 8, the print quantity address storage unit 23 detects the printer 101-3, and stores the obtained print quantity count address in association with the device model "type II", and at this time, the printer 101-3 becomes a known model, and the subsequent management server 102 can acquire the print quantity count therefrom.
The print count acquisition section 35 acquires a corresponding print count address from the print count address storage section 23 according to the device model acquired by the model information acquisition section 24 based on a predetermined print count acquisition rule, and acquires corresponding print count information from the printer information storage section 11 according to the print count address.
In this embodiment, the print count obtaining rule is obtained periodically, for example, once per week. When the print count information is acquired, the print count actually generated by the printer during one week can be acquired by subtracting the current print count from the previous print count.
After the print quantity count acquisition unit 35 acquires the print quantity count, the actual print quantity of the printer in this period can be acquired by simply subtracting the acquired print quantity counts from each other. Taking the print count "122" corresponding to "black-and-white a 4" on day 11, month 20 and the print count "183" corresponding to "black-and-white a 4" on day 11, month 27 of the printer 101-3 as an example, it successfully prints 61 print files of black-and-white a4, 183-.

In addition, in the embodiment, when the monitoring acquisition part acquires the printer information, the manufacturer private sub-tree root node is acquired through the manufacturer private sub-tree root node information, and all OID key values under the manufacturer private sub-tree are acquired through the manufacturer private sub-tree root node, so that the acquisition range of the printer information can be preliminarily reduced; and secondly, aiming at all OID key values under the private subtrees of the manufacturers, screening out the corresponding OID key values with the types of integer types and non-negative integer types, and acquiring printer information as the information to be compared according to the OID key values. Therefore, by the method, thousands of printer information stored in the MIB can be effectively screened to about 1000-2000 pieces, so that the data amount required to be processed by the subsequent comparison judgment part during comparison is reduced, and the identification efficiency is improved.
In addition, since the printer does not usually store the self-supported print supporting paper types, in this embodiment, the print parameter acquiring unit acquires the size of the printer paper cassette stored in the printer information storing unit through the print paper type acquiring unit, and further, by comparing the size of the paper cassette with the standard paper size of each paper type, effectively determines the paper type supported by the printer.
The above-described embodiments are merely illustrative of specific embodiments of the present invention, and the present invention is not limited to the description of the above-described embodiments.
For example, in the above-described embodiment, the print parameter acquisition section acquires the print color and the print paper type supported by the printer from the OID key values in the MIB of the printer. In other embodiments of the present invention, the print parameters supported by the printer may also be acquired according to the print driver installed corresponding to the printer, and the acquisition of the print parameters may also be implemented.
