Description

  The present invention relates to a print server technique for selecting a printing device suitable for print data from a plurality of printing devices arranged on a network.

  Conventionally, in a print server system in which a host device such as a PC or a plurality of printing devices and a print server are connected to a network, the print server inquires of the printing device connected to the network about each operation status and color information. Technology that stores and stores as printer characteristic information, selects a printing apparatus that satisfies the required characteristics of the print data transmitted from the host apparatus based on the printer characteristic information, and transmits the print data to the selected printing apparatus for printing (For example, see Patent Document 1).

JP-A-10-116165

  However, in the above conventional print server, a printing device having an excessively high function with respect to desired print data is selected and printed to consume wasteful power consumption, or a generally expensive printing with high speed and high function. There has been a problem in that the apparatus is frequently selected and used, and the expensive printing apparatus is frequently broken or replaced, resulting in unnecessary costs.

  For example, even though the user desires monochrome printing, a color printing device that is expensive and consumes a lot of power is selected, or even if it is A4 printing, B4 can be printed at a high price. A printing apparatus with a large amount of power is frequently selected, resulting in an increase in power consumption and expenses.

  The present invention employs the following configuration in order to solve the above problems. That is, in a print server that selects a printing device suitable for print data among a plurality of printing devices arranged on the network, a priority order that ranks the desired print data in the order of printing devices with less excessive functional performance A determination means is provided so that a printing apparatus having the minimum functional performance can be selected.

  According to the present invention described above, in a print server that selects a printing device suitable for print data from among a plurality of printing devices arranged on a network, in order of printing devices with less functional performance than desired print data. Since priority order determining means for ranking is provided so that a printing device having a minimum functional performance can be selected, it is possible to prevent selection of a printing device having excessive performance with respect to desired print data. It is possible to reduce wasteful power consumption and expenses.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element common to drawing.

  The print server according to the first embodiment is provided with a priority order determination unit that ranks printing apparatuses in the order of less excessive performance so that they can be used in the order of printing apparatuses in which the performance is less excessive.

(Constitution)
FIG. 4 is a configuration diagram of the print server system according to the first embodiment. As shown in the figure, in the print server system according to the first embodiment, the print server 21 is connected to the host apparatuses 3A to 3C and the printing apparatuses 4A to 4C via the network 2, and is transmitted from the host apparatuses 3A to 3C. Manage print jobs.

  FIG. 1 is a block diagram illustrating the configuration of the print server 21 according to the first embodiment. The print server 21 receives a print job from the host devices 3A to 3C and transmits the print job to the printing devices 4A to 4C, a control unit 25 that controls the print job, and prints the print job. The print data storage unit 26 stores data.

  The control unit 25 includes a printing device information storage unit 31, a priority order determination unit 32, a print attribute extraction unit 33, a printing device determination unit 36, a notification unit 37, and a print job input / output unit 39, which will be described later. Consists of

  The print job input / output unit 39 has a function of storing, in the print data storage unit 26, print data that the print server 21 receives from the host device 3A via the interface unit 27, and the print attribute extraction unit 33 It has a function of extracting print attributes from print data stored in the storage unit 26.

  As shown in FIG. 2, the printing device information storage unit 31 stores information such as printable size, color / monochrome, resolution, and presence / absence of a double-sided printing function for each printing device. The print attribute extracted from the attribute extraction unit 33 is compared with the functional performance of the printing device stored in the printing device information storage unit 31 to determine the print priority.

(Operation)
With the above configuration, the print server 21 according to the first embodiment operates as follows. This operation will be described in detail with reference to the flowchart of the printing operation of the print server 21 in FIG.

  First, when the print server 21 receives a print job from the host devices 3A to 3C connected via the network 2 (step S1), the print job input / output unit 39 temporarily stores it as print data in the print data storage unit 26. (Step S2).

  Then, it is determined whether or not there is a print job being processed in the control unit 25 (step S3). If there is a print job being processed, the process waits until the print job is completed, and there is no print job being processed. The print attribute extraction unit 33 extracts print attributes such as the size, color / monochrome, and resolution of the print job (step S4).

  Then, the priority order determination unit 32 compares the printing attributes extracted by the printing attribute extraction unit 33 with the information on the printing devices stored in the printing device information storage unit 31, and the priority order of the printing devices having the lowest possible performance is obtained. It determines so that it may become high (step S5).

  For example, when printing device information as shown in FIG. 2 is stored in the printing device information storage unit 31 and a print job as shown in FIG. 3A is received, the A4 size is monochrome, Since printing is performed as single-sided, low-resolution, and no post-processing, among the printing devices 4A to 4C, the printing device having the least excess performance with respect to print attributes is monochrome, single-sided, low-resolution, no post-processing. Since the printing apparatus 4A has functional performance, the priority of the printing apparatus 4A is set highest.

  Next, the printing apparatus 4B having functional performance of color printing, double-sided printing, and medium resolution, and finally the printing apparatus 4C having higher resolution and a post-processing function are set in this order (step S6).

  Examples of the excessive functional performance include A3 printing performance as the paper size, A3 printing performance, monochrome printing, color printing performance, and single-sided printing, duplex printing performance. . For example, when printing the print data for monochrome printing shown in FIG. 3A, color printing having ID (image drum) units for each color of C (cyan), M (magenta), Y (yellow), and K (black) is performed. When printing is performed with a printing apparatus having a function, the operation of moving up and down the C, M, and Y ID units is a wasteful operation, and wasteful power consumption occurs, resulting in excessive functional performance.

  Similarly, when a printing apparatus having an A3 size printing function is selected when A4 size printing is performed, the width of the charging roller or the like is wider than the width of the printing apparatus of A4 size or less, and the charging process is performed. The A3 size-A4 size portion is charged unnecessarily, and wasteful power is consumed, resulting in excessive performance.

  As a reference for the resolution in FIG. 3A, for example, a low resolution of 300 to 599 dpi, a medium resolution of 600 to 1199 dpi, and a high resolution of 1200 dpi may be used. Needless to say, the functional performance may be judged by classifying more finely or conversely roughly.

  When the printing apparatus information as shown in FIG. 2 is stored in the printing apparatus information storage unit 31 and a print job as shown in FIG. 3B is received, A4 size, color printing, medium resolution Therefore, the printing apparatuses capable of printing are the printing apparatuses 4B and 4C, and the printing apparatus 4B has the least excess performance with respect to the requested printing attributes. Therefore, the priority order is the printing apparatus 4B. The highest is set, and then the order of the printing apparatus 4C is set.

  Returning to the operation flowchart of FIG. 5 again, if the device designated on the printing device designation screen by the printer driver or the like matches the printing device with the highest priority (step S7), The print data is transmitted to the printing device (step S9). If the printing data is different, the user is prompted to change the printing device designated by the user to the highest-order printing device (step S8), and the user approves this. In this case, the print data is transmitted to the highest-order printing device (steps S10 and S9).

  On the other hand, when the user prints without changing the designation of the printing apparatus, the print data is transmitted to the printing apparatus designated by the user (step S11). Then, after transmitting the print data, the print data is deleted (step S12).

  In the above description of the print server according to the first embodiment, the printable size, color / monochrome, duplex printing function, resolution, and presence / absence of the finisher function are used as the priority determination criteria. A reference may be provided, or conversely, several may be selected and used as a determination reference. Alternatively, each criterion may be weighted, the number of excessive functional performances may be added, and the priority may be given by the added value.

(Effect of Example 1)
According to the above-described print server of the first embodiment, the priority order determination unit that ranks in the order of the printing devices with the least excessive performance is provided. Therefore, the printing device having the excessive performance with respect to the desired print data is selected. Can be prevented, and wasteful power consumption, cost, etc. can be reduced.

  The print server according to the second embodiment determines the printing order as in the first embodiment, and can select the optimum printing device based on the time required for printing in each printing device and the allowable occupation time.

(Constitution)
Since the configuration of the print server system according to the second embodiment is the same as the configuration according to the first embodiment described with reference to FIG. 4, the description thereof is omitted for simplification. FIG. 6 is a block diagram illustrating the configuration of the print server according to the second embodiment.

  As shown in the figure, in addition to the configuration of the control unit 25 of the first embodiment, the control unit 65 of the print server 61 of the second embodiment includes a printing time calculation unit 74, a printing apparatus operation status acquisition unit 75, which will be described later, and the like. The printing apparatus determination unit 76 and the allowable occupation time storage unit 78 are added. Other configurations are the same as the configuration of the print server 21 of the first embodiment, and thus detailed description thereof is omitted for the sake of brevity.

  The printing apparatus operation status acquisition unit 75 acquires the presence / absence of a waiting job from an apparatus having a high printing priority determined by the priority determination unit 32, and if there is a waiting job, the number of pages to be printed and the printing speed. It has the function to acquire.

  The printing time calculation unit 74 has a function of calculating the time required for printing from the information received from the printing apparatus operation status acquisition unit 75 and newly received print data, and the allowable occupation time storage unit 78 includes a printing apparatus. A function for storing the allowable occupation time set for each of the two.

  Here, for example, a printing apparatus capable of high-speed processing is generally expensive, and the allowable occupation time should be prevented from concentrating on the printing apparatus, and the occupation time should be set short. This setting may be freely set by the user in consideration of the function and performance of the printing apparatus, or the time for completing a predetermined printing process such as test printing is measured, and the measurement time is Accordingly, the printing apparatus that can process in a short time may be automatically set so that the allowable occupation time is shortened.

  The printing apparatus determination unit 76 of the print server 61 according to the second embodiment compares the printing time calculated by the printing time calculation unit 74 and the allowable occupation time stored in the allowable occupation time storage unit 78, and the user's time is within the time. If the print job matches the designated print device, the print job input / output unit 39 outputs a print job to the print device. If the print job is different from the user designated device, the notification unit 37 displays the priority on the host device, and the user Has a function of prompting the user to change the printing apparatus.

(Operation)
With the above configuration, the print server 61 according to the second exemplary embodiment operates as follows. This operation will be described with reference to the flowchart of the printing operation by the print server 61 of the second embodiment shown in FIG. Since steps S91 to S95 and S106 to S112 of the printing operation are the same as steps S1 to S5 and steps S6 to S12, the description thereof will be simplified.

  First, when the print server 61 receives a print job from the host devices 3A to 3C connected via the network 2, the print job input / output unit 39 temporarily stores the print data in the print data storage unit 26, When the print job being processed is not in the control unit 65, the print attribute extraction unit 33 extracts the print attribute of the print job. Then, the priority order determination unit 32 compares the printing attributes extracted by the printing attribute extraction unit 33 with the functional performance information of the printing apparatuses 4A to 4C stored in the printing apparatus information storage unit 31, and determines the priority order. (Steps S91 to S95).

  That is, as in the first embodiment, when a print job as shown in FIG. 3A is received, and printing device information as shown in FIG. 2 is stored in the printing device information storage unit 31. Then, since the printing apparatus having the least excessive performance with respect to the printing attribute is in the order of the printing apparatus 4A, the printing apparatus 4B, and the printing apparatus 4C, the priority order is set to this order.

  Then, the printing apparatus operation status acquisition unit 75 acquires the presence / absence of a waiting job from the printing apparatus with a high priority determined by the priority determination unit 32, and the number of prints and the printing speed when there is a waiting job. (Step S96).

  The printing time calculation unit 74 calculates the time required for printing based on the presence / absence of a waiting job acquired by the printing apparatus operation status acquisition unit 75, the number of printed sheets, and the printing speed information (step S97).

  For example, if the status of each of the printing apparatuses 4A to 4C is as shown in FIGS. 7 and 8, the printing apparatus 4A requires 18 minutes for the waiting print job, and is newly transmitted from the host apparatus. Then, the time required for the print job to be printed is 10 minutes, and it is calculated that a total of 28 minutes is required.

  Similarly, in the printing apparatus 4B, the time required for the waiting print job is 5 minutes, and the time required for the print job newly transmitted from the host apparatus is 7 minutes, which is 12 minutes in total. It is calculated that the time required for the job is 35 minutes, and the time required for the print job newly transmitted from the host device is 7 minutes, which requires 40 minutes in total.

  Then, the printing apparatus determination unit 76 compares the printing time calculated by the printing time calculation unit 74 with the allowable occupation time stored in the allowable occupation time storage unit 78 (step S98), and determines that the printing time is the allowable occupation time. If not, the printing device is determined as a printing device (connector B, step S106).

  In this example, the printing apparatus A with the highest priority takes 18 minutes for printing and 10 minutes for new printing, which takes a total of 28 minutes, but the allowable occupation time is set to 20 minutes. Therefore, the printing device 4B which does not satisfy the selection condition and is the next printing device in the priority order satisfies the selection condition because the time required for printing is set to 12 minutes and the allowable occupation time is set to 30 minutes. The printing device 4B is determined as the printing device.

  At this time, if the printing device 4B having the highest priority matches the device designated by the user on the printing device designation screen such as a printer driver, the print data is transmitted to the printing device 4B and is different. The user is prompted to change to the printing apparatus 4B, and when the user approves, print data is transmitted to the printing apparatus 4B. On the other hand, when the user does not approve, the print data is transmitted to the printing apparatus designated by the user, and after the print data is transmitted, the print data is deleted (steps S107 to S112).

  On the other hand, if S96 to S98 are repeated in order of priority and all the printing apparatuses have exceeded the allowable occupation time (step S99), the printing apparatus with the shortest excess time is selected (step S100), and the above-described process is performed. The processing in steps S106 to S112 is performed in the same manner.

(Effect of Example 2)
As described above, according to the second print server, the allowable occupation time storage unit that stores the allowable occupation time, the printing device operation status acquisition unit that acquires the printing device operation status, and the printing time that calculates the printing time. In addition to the effects of the first embodiment, it is possible to obtain desired printing in a shorter time since the calculation unit is provided and the printing apparatuses are ranked based on the difference between the time required for printing and the allowable occupation time. Can be provided.

  The print server according to the third embodiment adds a position information storage unit that stores position information and a position allowable range of the host device and the printing device to the print server according to the second embodiment, and prints at a location separated from the host device by a predetermined distance or more. This prevents printing from being output to the apparatus.

(Constitution)
Since the configuration of the print server system according to the third embodiment is the same as the configuration according to the first embodiment described with reference to FIG. 4, the description thereof is omitted for simplification. FIG. 6 is a block diagram illustrating the configuration of the print server according to the second embodiment.

  FIG. 10 is a block diagram of the print server according to the third embodiment. As shown in the figure, in the print server of the third embodiment, the position information storage unit 31a for storing the position information and the allowable position range of the printing device and the host device in the control unit in the configuration of the print server of the second embodiment. Is provided. Other configurations are the same as the configuration of the print server 21 of the second embodiment, and thus detailed description thereof is omitted for the sake of brevity.

  The position information may be registered in advance by a print server administrator or user. Further, the position information to be registered is, for example, by dividing the squares of the outline drawing of the floor partitioned in a lattice shape as shown in FIG. 11 and indicating the positions of the squares where the respective devices are arranged as shown in FIG. Input in association with the IP address.

  In the print server according to the third embodiment, when a print job is transmitted from the host device, the IP address of the host device is assigned to the header as the print job format as shown in FIG.

  Then, the distance between the host device and the printing device as a position allowable range that can be selected as the printing device is determined in advance by the number of grids, set by the server administrator, and stored in the position information storage unit 31a. Put. Alternatively, it is of course possible to allow the user to set this position tolerance during printing.

  For example, in the case where the arrangement positions of the host devices and the printing device are as shown in FIG. 11, since the host device 3A is in the vertical direction “4” and the horizontal direction “A”, it is registered as “4A”. Since it is in the vertical direction “3” and the horizontal direction “A”, it is registered as “3A”. Similarly, the position information of the host devices 3B and 3C is registered in the position information storage unit 31a as “4C” and “1C”, and the position information of the printing devices 4B and 4C is registered as “4B” and “2C”, respectively.

(Operation)
With the above configuration, the print server according to the third exemplary embodiment operates as follows. This operation will be described in detail with reference to the operation flowchart of FIG. Since steps S131 to S134 and S139 to S150 of the printing operation are the same as steps S91 to S94 and steps S96 to S112 of the second embodiment, the description thereof will be simplified.

  First, when the print server 121 according to the third embodiment receives a print job from the host apparatuses 3A to 3C connected via the network 2, the print job input / output unit 39 temporarily stores the print data in the print data storage unit 26. However, when there is no job currently being processed in the control unit 125, the print attribute extraction unit 33 extracts the print attribute of the print job and extracts the IP address of the client device (steps S131 to S134).

  Then, the priority order determination unit 72 identifies a host device that is a client from the IP address (step S135), reads position information corresponding to the IP address from the position information storage unit 31a (step S136), and is set in advance. A printing device that falls within the allowable position range is selected.

  For example, when a print job as shown in FIG. 13 is transmitted from the host apparatus 3A arranged as shown in FIG. 11, the priority order determination unit 72 starts from the client IP address described in the header part of the print job. The host device 3A is specified, and it is extracted that the host device 3A is located at the position “4A”.

  Accordingly, since the print job of FIG. 13 is A4, monochrome, single-sided, low resolution, and no finisher printing, any of the printing devices 4A, 4B, and 4C is printed from the function table of each printing device of FIG. Elected as possible.

  When the allowable position range is set to be within 2 squares, the printing apparatus 4C is located at a distance of 2 horizontal squares + 2 vertical squares = total 4 squares from the host apparatus 3A, and is disposed outside the allowable positional range. Therefore, the printing device 4A and the printing device 4B that are separated by only one square are selected (step S137).

  Next, the printing apparatus information of the selected printing apparatus shown in FIG. 2 is compared with the printing attributes described in the header part of FIG. 13, and a priority is given to the print job with the least number of functions. In this example, since the printing device 4A has fewer excessive functions, the printing devices 4A and 4B are arranged in this order (step S138).

  Next, the printing apparatus operation status acquisition unit 75 determines whether there is a waiting job from a printing apparatus with a high priority determined by the priority determination unit 72, and if there is a waiting job, the number of prints and the printing speed. Obtain (step S139).

  The printing time calculation unit 74 calculates the time required for printing based on information such as the presence / absence of a waiting job acquired by the printing apparatus operation status acquisition unit 75, the number of prints, and the printing speed (step S140).

  For example, if the states of the printing apparatuses 4A and 4B are as shown in FIGS. 7 and 8, the printing apparatus 4A takes 18 minutes to complete a waiting print job and is newly transmitted from the host apparatus. The time required for the print job to be printed is 10 minutes, and it takes 28 minutes in total. In the printing apparatus 4B, the time required for the waiting print job is 5 minutes, and the print newly sent from the host device It acquires that the time required for the job is 7 minutes in total, 12 minutes.

  Then, the printing device determination unit 76 compares the printing time calculated by the printing time calculation unit 74 with the allowable occupation time stored in the allowable occupation time storage unit 78, and the printing device whose printing time does not exceed the allowable occupation time. Are determined (S141 and S144).

  In this example, the printing apparatus A with the highest priority takes 18 minutes for printing and 10 minutes for new printing, which takes a total of 28 minutes, but the allowable occupation time is set to 20 minutes. It does not meet the selection conditions. The printing apparatus 4B, which is the next printing apparatus in the priority order, has a total printing time of 12 minutes and an allowable occupation time of 30 minutes. Therefore, the selection condition is satisfied, and the printing apparatus 4B is determined as the printing apparatus. The

  At this time, if the printing device 4B having the highest priority matches the device designated by the user on the printing device designation screen such as a printer driver, the print data is transmitted to the printing device 4B and is different. The user is prompted to change to the printing apparatus 4B, and when the user approves, print data is transmitted to the printing apparatus 4B. On the other hand, when the user does not approve, the print data is transmitted to the printing apparatus designated by the user, and after the print data is transmitted, the print data is deleted (steps S145 to S150).

  On the other hand, if S139 to S142 are repeated in order of priority and all the printing apparatuses have exceeded the allowable occupation time (step S142), the apparatus having the shortest excess time is selected (step S143), and the above-described steps are performed. The processing of S144 to S150 is performed in the same manner.

  In the above description, the position information of the host device and the printing device is described as being registered by the administrator or the user. However, although it is somewhat expensive, a device that can detect the position information on each floor, for example, a wireless signal A position information detecting device that detects position information from the arrival delay time may be provided in each device so that the position information is automatically detected and stored in association with the IP address.

  In the above description, the priority order is determined after excluding printing apparatuses outside the allowable position range. However, after determining the priority order of the printing apparatuses, the printing apparatus outside the allowable position range is excluded. You may make it do.

  In the above description, the distance between the host apparatus and the printing apparatus is calculated as the Manhattan distance by the squares. However, it may be calculated as an actual distance such as the Euclidean distance.

  Further, in the above description, it has been described that the printing device within the position allowable range is selected and the priority order of the selected printing device is determined. However, the number of functional performances that are not excessive, the margin time for the allowable occupation time, the host The proximity from the apparatus may be given a predetermined weight, the printing apparatuses may be ranked according to the result, and the printing apparatuses may be selected in order from the top.

(Effect of Example 3)
As described above, according to the print server of the third embodiment, the printing apparatus is provided with the position information storage unit that stores the position information and the position allowable range of the host apparatus and the printing apparatus, and is located at a predetermined distance or more from the host apparatus. Therefore, in addition to the effects of the first and second embodiments, there is no printing on a printing device at a remote location.

<< Other modifications >>
