Hereinafter, an example of a preferred embodiment for realizing the present invention will be described with reference to the drawings.
FIG. 1 shows a conceptual module configuration diagram of a configuration example of the present embodiment.
The module generally refers to components such as software (computer program) and hardware that can be logically separated. Therefore, the module in the present embodiment indicates not only a module in a computer program but also a module in a hardware configuration. Therefore, the present embodiment is a computer program for causing these modules to function (a program for causing a computer to execute each procedure, a program for causing a computer to function as each means, and a function for each computer. This also serves as an explanation of the program and system and method for realizing the above. However, for the sake of explanation, the words “store”, “store”, and equivalents thereof are used. However, when the embodiment is a computer program, these words are stored in a storage device or stored in memory. This means that control is performed so as to be stored in the apparatus. Modules may correspond to functions one-to-one, but in mounting, one module may be configured by one program, or a plurality of modules may be configured by one program, and conversely, one module May be composed of a plurality of programs. The plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers in a distributed or parallel environment. Note that one module may include other modules. Hereinafter, “connection” is used not only for physical connection but also for logical connection (data exchange, instruction, reference relationship between data, etc.). “Predetermined” means that the process is determined before the target process, and not only before the process according to this embodiment starts but also after the process according to this embodiment starts. Also, if it is before the target processing, it is used in accordance with the situation / status at that time or with the intention to be decided according to the status / status up to that point. When there are a plurality of “predetermined values”, the values may be different from each other, or two or more values (of course, including all values) may be the same. In addition, the description of “do B when A” is used to mean “determine whether or not A and do B when A”. However, the case where it is not necessary to determine whether or not A is excluded. In addition, when enumerating things such as “A, B, C”, etc., it is an enumerated list unless otherwise specified, and includes cases where only one of them is selected (for example, only A).
In addition, the system or device is configured by connecting a plurality of computers, hardware, devices, and the like by communication means such as a network (including one-to-one correspondence communication connection), etc., and one computer, hardware, device. The case where it implement | achieves by etc. is included. “Apparatus” and “system” are used as synonymous terms. Of course, the “system” does not include a social “mechanism” (social system) that is an artificial arrangement.
In addition, when performing a plurality of processes in each module or in each module, the target information is read from the storage device for each process, and the processing result is written to the storage device after performing the processing. is there. Therefore, description of reading from the storage device before processing and writing to the storage device after processing may be omitted. Here, the storage device may include a hard disk, a RAM (Random Access Memory), an external storage medium, a storage device via a communication line, a register in a CPU (Central Processing Unit), and the like.

  The display device 100 according to the present embodiment graphically displays operation state information (may include future prediction information) of the printing device recorded as a print processing history on the time axis. As shown in the example of FIG. 1, a reception module 105, a transmission module 110, a print job identification module 115, a print job information storage module 120, a time chart display module 125, and an image processing control module 170 are included.

The display device 100 visually displays a print history (processing history) of a print job in time series. It has a so-called timeline function. Specifically, the start date and time of the print history of the print job (when the date is referred, it may be year, month, day, hour, minute, second, second or less, or a combination thereof) and end date and time are set. The events of the print job and the state of the printing apparatus occurring during that time are visualized and displayed in time series.
The display device 100 can also display a list of print jobs processed within an arbitrary time range between the start date and time and the end date and time. The time range can be arbitrarily changed according to the user's designated operation. For example, as an example in which the time range advances from “narrow” to “wide”, there are 10 minutes, 30 minutes, 1 hour, 12 hours, 1 day, 1 week, all, and the like.
It is possible to change the history display time range of the start date and time and the end date time with the specified time range. In other words, if the start date / time is changed, the time range is fixed, so the end date / time is also changed as the start date / time is changed. For example, as described later, the history display time range is changed by moving (sliding) the scroll bar (display time zone) 910 shown in FIG. 9 to the left and right.
In addition, in the display device 100, a target to be displayed in time series displays prediction information in the future from the current time in addition to the past history from the current time. For example, as will be described later, the left side of the current time display line 1030 shown in FIG. 10 indicates the past history, and the right side of the current time display line 1030 indicates the future prediction.

The reception module 105 is connected to the print job identification module 115. The reception module 105 receives a user operation. The operation may be an operation received from a user terminal 280, which will be described later using the example of FIG. . As a user operation, for example, a print job selected by the user is accepted. A plurality of print jobs may be selected.
The transmission module 110 is connected to the time chart display module 125. The transmission module 110 transmits the processing result by the time chart display module 125 (particularly, the display control module 160) to the user terminal 280. For example, display control is performed on the browser of the user terminal 280. Further, the drawing module 165 may perform display processing on a display device (liquid crystal display or the like) included in the display device 100.

The print job identification module 115 is connected to the reception module 105, the print job information storage module 120, and the time chart display module 125. The print job specifying module 115 specifies a print job selected by the user from a plurality of print jobs displayed in the display area. The selection here is made by a user operation using a keyboard, mouse, touch panel, or the like.
Further, the print job specifying module 115 specifies a print job that satisfies a search condition specified for selecting a print job. The selection after the search includes not only the selection by the user's operation using the keyboard, mouse, touch panel, etc., but also the search result when the print job is searched. That is, even if there is no explicit user selection operation, the search result itself (or search instruction) may correspond to the selection operation.
Further, the print job identification module 115 acquires, from the print job information storage module 120, print job history information that includes a print processing start time or end time within a specified period.
The print job information storage module 120 is connected to the print job identification module 115 and the image processing control module 170. The print job information storage module 120 stores a print job and a print job history. For example, a print job information table 500 and a print job (event) log table 600 described later are stored.

The time chart display module 125 includes a setting module 130, a drawing rule storage module 155, a display control module 160, and a drawing module 165, and is connected to the transmission module 110 and the print job specifying module 115. The time chart display module 125 is a module for realizing a timeline function, and graphically displays (controls display) a print job history and a prediction of the status (status) of a print job to be processed.
The setting module 130 includes a display position setting module 135, a display range setting module 140, an enlargement / reduction ratio determination module 145, and a drawing rule determination module 150. The setting module 130 determines the position, display range, enlargement / reduction ratio, and drawing rule of the target print job in the display area.

The display position setting module 135 is a starting point on the time axis when events related to the target print job are displayed in the display area in time series according to the attributes of the print job specified by the print job specifying module 115 And / or set the end point. Here, the “target print job” is a print job specified by the print job specifying module 115. The “print job attribute” includes the status of the print job. Specifically, it refers to the status (status) of processing at the present time, and includes normal termination, reserved job (print job for which processing has not started), and error occurrence. The “event related to the print job” indicates processing contents (also referred to as a process) from the reception to the end of the print job. Specifically, the reception, the first stage image generation process, the second stage image There are generation processing, printing, and the like. Further, the state of these processes (specifically, normal end, reserved job, error occurrence, etc.) may be included in correspondence with the process.
“Starting point on the time axis” is the position that indicates the start of processing when the processing is represented in a graph on the time axis. Specifically, when the past is left and the future is right on the time axis The position of the left end of the process.
"End point on the time axis" is the position that indicates the end of processing when the processing is represented in the graph on the time axis. Specifically, when the past is left and the future is right on the time axis The right end position of the process.
For example, the display area is divided into a list area for displaying a print job list and a graphical area for graphically displaying events (processes) executed in each print job in time series. In the list area, an identifier (job ID, job name, etc.) for uniquely identifying each job may be displayed. Of course, a print job displayed in the list area corresponds to a print job event displayed in the graphical area.
The list area is preferably sorted in ascending or descending order by the start time or end time of each print job. This is because events are also displayed for print jobs that have been processed before / after on the time axis of the selected print job, especially for print jobs in which an error has occurred. Because there is.

Also, the display position setting module 135 shifts the time axis so that the start time of the print job specified by the print job specifying module 115 becomes the left end of the display area when the attribute of the print job is normal end. May be.
In addition, when the print job attribute is reserved, the display position setting module 135 shifts the time axis so that the predicted end time of the print job specified by the print job specifying module 115 becomes the right end of the display area. May be.
In addition, when the print job attribute is an error occurrence, the display position setting module 135 sets the time axis so that the start time of the print job specified by the print job specifying module 115 is between the left end and the right end of the display area. You may make it shift. Here, as “between the left end and the right end of the display area”, the time axis is shifted so as to be displayed at substantially the center of the display area (for example, within a predetermined section from the center).

  The display range setting module 140 sets the leftmost date and time and the rightmost date and time in the display area in accordance with a user operation. For example, an operation on a scroll bar (display time zone) 910 shown in FIG. That is, by changing the size (length) of the scroll bar (display time zone) 910, the history display time range (period length) in the display area is designated. Then, by moving the scroll bar (display time zone) 910 on the time-series display area B820, the start point and end point in the display area are designated.

The enlargement / reduction rate determination module 145 determines the reduction rate or enlargement rate on the time axis according to the attributes of the print job.
When the attribute of the print job A is an error, the enlargement / reduction ratio determination module 145 displays the print job processed before the print job A and the print job processed after the print job A. The reduction rate or enlargement rate on the time axis is determined so that the end of the event is within the display area.
For example, when the display ratio of the target print job is less than or less than a predetermined ratio on the time axis of the display area, enlargement processing is performed.
The enlargement / reduction rate determination module 145 displays the start time of the first event and the end time of the last event when events related to the print job satisfying the search condition are displayed in the display area in time series. The enlargement / reduction ratio on the time axis is determined so as to be within the region.
The enlargement / reduction ratio determination module 145 may determine the enlargement / reduction ratio when the print job specified by the print job specification module 115 is not displayed in the display area.

The enlargement / reduction ratio determination module 145 may not perform the enlargement / reduction ratio determination process when the print job specified by the print job specification module 115 is displayed in the display area.
In this case, when the print job specified by the print job specifying module 115 is displayed in the display area, the display position setting module 135 displays events related to the print job in chronological order according to the attributes of the print job. Set the start point and / or end point on the time axis when displaying them side by side in the display area.

  Further, the enlargement / reduction rate determination module 145 uses the history information acquired by the print job specifying module 115 to arrange a plurality of events related to the print job on one time axis, and displays a display area along the time axis. The magnification for displaying in the box is calculated.

The drawing rule determination module 150 is connected to the drawing rule storage module 155. The drawing rule determination module 150 acquires status information of a plurality of events related to processing using the print job history information acquired by the print job specifying module 115, and is specified by the start time and end time of each event. A drawing rule for expressing the event processing time in a rectangle is determined by the status information.
The drawing rule storage module 155 is connected to the drawing rule determination module 150 of the setting module 130. The drawing rule storage module 155 stores drawing rules in the display area. For example, a print job type / display position / display range table 700 described later, a selection method / display position / display range table 2000, an event status / display color / weight table 2400, and the like are stored.

The display control module 160 is displayed in accordance with the start point and / or end point set by the display position setting module 135 and the event related to the target print job, and before and / or after the print job in the display area. Controls the display position of each event related to a print job.
Further, the display control module 160 may control to display an event related to a print job without performing enlargement or reduction.
Further, the display control module 160 performs control to enlarge and reduce the event sequence related to the print job satisfying the search condition and display it in the display area based on the enlargement / reduction ratio determined by the enlargement / reduction ratio determination module 145.
In addition, the display control module 160 converts the rectangle representing each event with the magnification calculated by the enlargement / reduction ratio determination module 145 according to the weight associated with the type of status information indicating the processing result of each event. Reduce the direction and draw in the display area. Note that “weighting” includes the concept of priority. Giving the maximum weight means that the priority is the highest. Small weight means low priority.
Further, the display control module 160 may perform control so as to perform drawing according to the drawing rule determined by the drawing rule determination module 150. In addition, an event to which the maximum weight is given in the drawing rule may not be reduced to a size equal to or smaller than the minimum drawing unit even if the event is reduced by the magnification calculated by the enlargement / reduction ratio determination module 145. Here, “does not reduce below the minimum drawing unit size” means, for example, that drawing is performed with a width of one pixel even if the reduction result is less than one pixel.
The display control module 160 also displays the status of the adjacent event when the gap is eliminated by reducing the gap between the adjacent events across the gap by the magnification calculated by the enlargement / reduction ratio determination module 145. When the types of information are the same, it may be controlled to draw adjacent events as one event.
Further, the display control module 160 controls to reduce at a magnification calculated by the enlargement / reduction ratio determination module 145 in preference to an event having a small weight when the types of status information of adjacent events without gaps are different. Also good.
The drawing module 165 performs display processing on the display device according to control by the display control module 160.

The image processing control module 170 is connected to the print job information storage module 120, the intermediate form generation module 175, the image generation module 180, and the print module 185. The image processing control module 170 controls the intermediate form generation module 175, the image generation module 180, and the print module 185 to perform print processing according to the print job.
The intermediate form generation module 175 is connected to the image processing control module 170 of the display device 100. The intermediate form generation module 175 performs a first stage image generation process. Specifically, intermediate form document data is generated from a document to be printed in a print job. Here, the intermediate form document data has a data structure in the previous stage of generating the print data, and it is difficult to generate the print data directly from the document. Therefore, the intermediate form document data is once generated. It is easier to generate intermediate form document data from a document than to generate print data directly from a document. It is easier to generate print data from intermediate document data than to generate print data directly from a document.
The image generation module 180 is connected to the image processing control module 170 of the display device 100. The image generation module 180 performs a second stage image generation process. Specifically, print data (image) that can be printed by the print module 185 is generated from the intermediate form document data generated by the intermediate form generation module 175.
The print module 185 is connected to the image processing control module 170 of the display device 100. The print module 185 performs printing according to the print job.

FIG. 6 is an explanatory diagram showing an example of the data structure of the print job (event) log table 600. The print job (event) log table 600 has a print job ID column 602 and an event column 604. The event field 604 includes a reception field 606, an intermediate form generation field 616, an image generation field 626, and a print field 636. This corresponds to four events in the printing process. Specifically, (1) print job reception process, (2) intermediate form generation process (process by intermediate form generation module 175), (3) image generation process (process by image generation module 180), (4) printing There is processing (processing by the printing module 185). Each has event ID, start date / time, end date / time, and result information. That is, the reception column 606 includes an event ID column 608, a start date / time column 610, an end date / time column 612, and a result column 614. The intermediate form generation column 616 includes an event ID column 618, a start date / time column 620, and an end date / time. The image generation field 626 has an event ID field 628, a start date / time field 630, an end date / time field 632, and a result field 634, and the print field 636 has an event ID field. 638, start date and time column 640, end date and time column 642, and result column 644.

The end date / time column 642 stores the end date / time. The result column 644 stores the result.
For example, the first line of the print job (event) log table 600 includes “1” in the print job ID column 602, “E-001” in the event ID column 608 for the reception column 606, and “XXXX / XX in the start date / time column 610. / XX / XX / XX / XX ”,“ XXXX / XX / XX / XX / XX / XX ”in the end date / time column 612,“ normal end ”in the result column 614, and“ event completion ”in the event ID column 618 in the event form column 616 "E-002", "XXXX / XX / XX / XX / XX / XX" in the start date / time column 620, "XXXX / XX / XX / XX / XX / XX" in the end date / time column 622, and "normal end" in the result column 624 ”,“ E-003 ”in the event ID column 628,“ XXXX / XX / XX / XX / XX / XX ”in the start date / time column 630, and“ X ”in the end date / time column 632. XX / XX / XX / XX / XX / XX ”,“ normal end ”in the result column 634,“ E-004 ”in the event ID column 638 for the print column 636, and“ XXXX / XX / XX / XX in the start date / time column 640 ” / XX / XX ”,“ XXXX / XX / XX / XX / XX / XX ”in the end date / time column 642, and“ Error occurrence (paper jam) ”in the result column 644. That is, the print job: 1 indicates that the reception process, the intermediate form generation process, and the image generation process ended normally, but an error (paper jam) occurred in the last print process.
The second line of the print job (event) log table 600 includes “2” in the print job ID column 602, “E-021” in the event ID column 608 for the reception column 606, and “XXXX / XX / XX” in the start date / time column 610. / XX / XX / XX ”,“ XXXX / XX / XX / XX / XX / XX ”in the end date / time column 612,“ normal end ”in the result column 614, and“ E- ”in the event ID column 618 for the intermediate form generation column 616. 022 ”,“ XXXX / XX / XX / XX / XX / XX ”in the start date / time column 620,“ XXXX / XX / XX / XX / XX / XX ”in the end date / time column 622,“ normal end ”in the result column 624, Regarding the image generation field 626, “E-023” is stored in the event ID field 628, “XXXX / XX / XX / XX / XX / XX” is displayed in the start date / time field 630, and “XXXX / X / XX / XX / XX / XX ”,“ normal end ”in the result column 634,“ E-024 ”in the event ID column 638 for the print column 636, blank (null) in the start date / time column 640, and null in the end date / time column 642 “Processing schedule (waiting for printing)” is stored in the blank (null) and result column 644. That is, the print job: 2 indicates that the reception process, the intermediate form generation process, and the image generation process are normally completed, but the last print process is unprocessed (waiting for printing). Note that the start date and time and end date and time of prediction may be stored in the start date and time column 640 and the end date and time column 642, respectively.

In step S406, the attribute of the print job is determined. If “normal end”, the process proceeds to step S408. If “reserved”, the process proceeds to step S412. If “error occurs”, the process proceeds to step S416. For example, the determination may be made using information in the result column 644 (or the result column 614 other than the normal end, the result column 624, and the result column 634) in the print column 636 of the print job (event) log table 600.
In step S408, the starting point at the start of the print job is set as the left end of the display area. For example, information in the start date / time column 610 in the reception column 606 of the print job (event) log table 600 may be used. In this process, a start point on the time axis when events related to the print job are displayed in the display area in time series is set according to the attribute of the specified print job.

In step S410, the setting of the current enlargement / reduction ratio (magnification) is taken over, and the process proceeds to step S424. That is, enlargement / reduction is not performed. Therefore, since the starting point on the time axis and the enlargement / reduction ratio are determined, in this process, when events related to the print job are displayed in the display area in chronological order according to the attribute of the specified print job The end point on the time axis is set. In addition, since the attribute of the print job is a normal end, the time axis is shifted so that the start time of the specified print job is at the left end of the display area.
If enlargement / reduction is performed each time a print job is selected, it may not be clear whether the target print job is the same, and the user may be confused. Therefore, enlargement / reduction is not performed so that the user is not confused. The same applies to the processing in step S414 and step S422.

In step S412, the end point at the end of the prediction of the print job is set as the right end of the display area. As described above, the prediction end time may be calculated using information (number of pages, etc.), schedule (printing order), printing speed of the printing apparatus, and the like in the print job. In this process, according to the attribute of the specified print job, an end point on the time axis when events related to the print job are displayed in the display area in time series is set.
In step S414, the current enlargement / reduction ratio (magnification) setting is taken over, and the process proceeds to step S424. Therefore, since the end point on the time axis and the enlargement / reduction ratio are determined, in this process, when events related to the print job are displayed in the display area in time series in accordance with the attribute of the specified print job The starting point on the time axis is set. Further, since the print job attribute is reserved, the time axis is shifted so that the predicted end time of the specified print job is at the right end of the display area.

  In step S416, the starting point at the start of the print job is set within the display area (between the left end and the right end). For example, information in the start date / time column 610 in the reception column 606 of the print job (event) log table 600 may be used. In this process, a start point on the time axis when events related to the print job are displayed in the display area in time series is set according to the attribute of the specified print job. Since the print job attribute is an error occurrence, the time axis is shifted so that the start time of the specified print job is between the left end and the right end of the display area. For example, the center of the event of the print job may be moved so that the center of the graphic area 870 coincides, or the print job before and after the target print job is moved so that the entire print job fits in the graphic area 870. May be.

  In step S418, “at the start of an event for a print job processed before the target print job” and “at the end of an event for a print job processed after the target print job” at the current magnification, It is determined whether or not it fits within the display area. If so, the process proceeds to step S422. Otherwise (if not fit), the process proceeds to step S420.

In step S420, at least at the start of an event for a previously processed print job (including, of course, at the end) and at the end of an event for a later processed print job (of course, at the start Is set so that it falls within the display area, and the process proceeds to step S424. In this process, since the attribute of the print job is an error occurrence, the event of the print job processed before the print job (the print job in which the error occurred) and the print job (the print in which the error occurred) are processed. Reduction or enlargement is performed on the time axis so that the event end time of the print job processed after (job) is within the display area.
Note that the enlargement / reduction (magnification) is changed by the print job that caused the error or the influence of the error rather than the target print job (print job that caused the error). This is because it is important to know the print job. That is, enlargement / reduction is performed so that the entire print job before and after the target print job can be grasped.

In step S422, the current enlargement / reduction ratio (magnification) setting is taken over, and the process proceeds to step S424.
In step S424, the display area is drawn according to the set display position and magnification. That is, according to the set start point and / or end point, the respective display positions of the event related to the target print job and the event related to the print job displayed before and / or after the print job in the display area To control.

The processing according to the flowchart illustrated in the example of FIG. 4 may be performed in accordance with the print job type / display position / display range table 700. That is, the drawing rule determination module 150 extracts the print job type / display position / display range table 700 in the drawing rule storage module 155, and in accordance with the print job type / display position / display range table 700, the display position setting module 135. The display range setting module 140 and the enlargement / reduction rate determination module 145 may perform processing.
FIG. 7 is an explanatory diagram showing an example of the data structure of the print job type / display position / display range table 700. The print job type / display position / display range table 700 includes a print job type column 710, a display position column 720, and a display range column 730. The print job type column 710 stores the type of print job. The display position column 720 stores the display position. The display range column 730 stores a display range.

  For example, in the first line of the print job type / display position / display range table 700, “print job type” column 710 “process scheduled job (future prediction display job)” and display position column 720 “event end date / time display range”. “Move to the end date and time (the right end of the display area)”, “Move to the range from the start to the end of the selected job” is stored in the display range column 730, and the second line is “Error job” in the print job type column 710 In the display position column 720, “match event to the center of the display range” is stored, and in the display range column 730, “match to the range of the event start date and time of the previous job and the event end date and time of the subsequent job” are stored. “Print job type” column 710 “normally completed job”, display position column 720 “match event start date and time with display range start date and time (left end of display area)”, display range Stores "match the range of from the start to the end of the job of the event" to 730.

The display area will be described using the example of FIG. FIG. 8 is an explanatory diagram showing a display example according to the present embodiment. The display area corresponds to the graphic area 870.

The printing device processing graphic area 872 displays the processing content (event) in the printing device in a graphic form. For example, the elements (rectangles) indicating “receiving”, “generating intermediate form document data”, “printing data generation”, “printing (printing)”, “waiting for user operation”, etc. are color-coded. indicate. Further, the processing result (normal end, warning, error, etc.) may be displayed in different colors.
From the second line onward in the list area 850, print jobs within the period specified by the scroll bar (display time zone) 910 (in addition, if the search expression reception field 830 is used, the search expression reception field 830). The print job searched according to the search expression received in step (1) is displayed. For example, a list of print job names and results may be displayed.
From the second line onward in the graphic area 870, the processing content of the print job is displayed in a graphic. For example, the elements (rectangles) indicating “receiving”, “generating intermediate form document data”, “printing data generation”, “printing (printing)”, “waiting for user operation”, etc. are color-coded. indicate. Further, the processing result (normal end, warning, error, etc.) may be displayed in different colors.

FIG. 9 is an explanatory diagram showing a display example according to the present embodiment. A specific example is displayed in the screen 800 shown in the example of FIG.
This is a visual display of the print history of a print job in chronological order (timeline function).
In the target period setting field 810, the start date and time and the end date and time of the print history of the print job are set, and the event of the print job and the state of the printing apparatus that occurred during that time are visualized and displayed in time series. .
When the user operates the target period setting field 810, a list of print jobs processed within an arbitrary time range between the start date and time and the end date and time can be displayed in the list area 850. The time range can be arbitrarily changed by the user in the target period setting field 810.
Then, by sliding the scroll bar (display time zone) 910 on the time series display area B820, the time range in the graphic area 870 of the start date and the end date can be changed with the specified time range. Is possible. The scroll bar (display time zone) 910 will be described in detail later using the example of FIG.

FIG. 10 is an explanatory diagram showing a display example according to the present embodiment.
In the example of FIG. 10, a current time display line 1030 is displayed in the graphic area 870. The left side of the current time display line 1030 is the past history, and the right side (future prediction display area 1040) of the current time display line 1030 indicates the future prediction. Of course, the print history of the print job may be used for the past of the current time. The future from the current time may be calculated according to the schedule of the future print job. Specifically, the prediction information includes print data generation processing (processing speed of the intermediate form generation module 175 and image generation module 180) based on print job settings, printer printing speed (printing speed of the printing module 185), and finishing processing. It may be calculated in accordance with (punch (drilling), document binding (stapling), paper folding, etc.). In addition to these, the start date and time and end date and time of each print job may be calculated from the start date and time, the print job amount (number of sheets, paper size, print type (color / monochrome print), etc.), print order, and the like.

FIG. 11 is an explanatory diagram showing a display example according to the present embodiment.
The display time zone can be changed by sliding (moving) the display time zone 1110 on the time-series display area B820. The graphic area 870 (including the printing apparatus processing graphic area 872) is displayed corresponding to the time slot where the display time slot 1110 is located. The display time period 1110 can be changed by a user operation.
In the time series display area B820, the time axis from 0:00 to 24:00 on March 7, 2017 (Tuesday) is shown. That is, the state of the printing device on the start date and the end date is displayed on the time series display area B820.
The time period (30 minutes) from 9:28:49 on March 7, 2017 (Tuesday) to 9:58:49 is specified by the display time zone 1110 in the time series display area B820. The details of the period are displayed in the graphic area 870. That is, the user can change the time range in the graphic area 870 by sliding the display time period 1110 while viewing the state of the printing apparatus on the time-series display area B820.
Note that details of the display time period 1110 are displayed in the printing apparatus processing graphic area 872. Conversely, a reduced version of the printing apparatus processing graphic area 872 is displayed in the display time zone 1110. In the printing apparatus processing graphic area 872, there are a printing presentation bar 1122 indicating a state of the printing apparatus, a user operation waiting presentation bar 1124, a printing presentation bar 1126, and a printing presentation bar 1128.

FIG. 12 is an explanatory diagram showing a display example according to the present embodiment.
FIG. 12A shows the processing contents in the time zone from March 27, 2017 19: 27: 9 to March 27, 2017 19:45:38.
Here, when the target print job 1210 is selected by a user operation, it is displayed as shown in the example of FIG. That is, the event of the target print job 1210 is scrolled so that the start time of the graphic area 870 is reached. Specifically, the graphic area 870 is displayed with the left end of March 27, 2017, 19:29:25, which is the start time of processing of the target print job 1210. Of course, the graphic area 870 of another print job is also displayed with the left end of March 27, 2017, 19:29:25. That is, the entire graphic area 870 is shifted to the left and displayed.
As a result, even if the print job event displayed in the list area 850 is outside the graphic area 870, the print job event is scrolled and displayed by selecting the print job. It becomes possible to do.

FIG. 13 is an explanatory diagram showing a display example according to the present embodiment.
In the screen 800, it is possible to search for a print job using the search expression reception field 830. That is, it is possible to search for arbitrary parameters (print job name, end status, etc.) of the print job. In the list area 850, jumps are made to print jobs that hit the search (a jump is a list including the print job that is the search result). Scroll so that the event start date and time of the print job is the start time of the display range.
For example, when “XXB” is searched in the search expression reception field 830 (see FIG. 13C) in FIG. 13A, a print job including “XXB” in the print job name is searched. Then, as shown in the example of FIG. 13B, the search print job 1310 that is the search result in the list area 850 is highlighted so that the event start date and time of the search print job 1310 is at the left end of the graphic area 870. Scrolling.
Note that according to the flowchart shown in the example of FIG. 4, the display position of the event related to the search print job 1310 may be changed according to the attribute of the search print job 1310.
If there are a plurality of hit print jobs as a search result, the next search print job is selected by pressing the triangle buttons (the right triangle button and the left triangle button) in the search expression reception field 830 shown in the example of FIG. You may make it display.

FIG. 14 is an explanatory diagram illustrating a display example of comparison.
Regardless of the print job attribute, if the event origin of the selected print job is always aligned with the left end of the graphic area 870 (that is, when this embodiment is not adopted), the selected print job The print job in front of the job is not displayed in the graphic area 870. Specifically, as shown in the example of FIG. 14, when a print job in which an error has occurred in the target print job 1410 is selected, the event of the previous print job (down one in the list area 850) is displayed in the display range. Get out.
However, for a print job scheduled to be processed (print job predicted in the future), the end date / time is more important than the event start date / time, so the end date / time should also be displayed in the graphic area 870. In addition, if it is an error job, there is a desire to grasp the status of the print job before and after the occurrence of the error.

FIG. 15 is an explanatory diagram illustrating a display example of comparison.
This shows an example in which the display range (display scale) is not changed even when a print job is selected. As shown in the example of FIG. 15A, even when an event in a wide range of time is displayed in the graphic area 870, even if the print job 1510 of the event 1520 that is completed in a short time is selected, As shown in the example of FIG. 15B, the event 1520 has only moved to the left end, and it is difficult to determine what is happening. In particular, when an error occurs in the print job 1510, the print job before the print job 1510 and the entire print job after the print job 1510 should be enlarged or reduced so as to be understood.

FIG. 16 is an explanatory diagram showing a display example according to the present embodiment.
A print job 1610 in the list area 850 is a print job in which an error has occurred. In this case, the user wants to grasp the entire pre-error event group 1630 of the print job that ended before the print job 1610 (event 1620) and the post-error event group 1640 of the print job that occurred after.

FIG. 17 is an explanatory diagram illustrating a display example of comparison.
Regardless of the print job attribute, when the event origin of the selected print job is always set to the left end of the graphic area 870 (that is, when this embodiment is not adopted), printing in the list area 850 is performed. When the job 1610 is selected, as shown in the example of FIG. 17, the pre-error event group 1630 of the previous print job (one lower in the list area 850) is out of the display range.

FIG. 18 is an explanatory diagram showing a display example according to the present embodiment.
In this embodiment, when the print job 1610 in the list area 850 is selected, as shown in the example of FIG. 18, the pre-error print job 1830 before the print job 1610 (one down in the list area 850). The post-error occurrence event group 1640 of the post-error occurrence print job 1840 after the print job 1610 (up by one in the list area 850) is set to the left end of the graphic area 870. The slide processing and the enlargement / reduction processing are performed so that the end point (at the end of the event) is the right end of the graphic area 870.

FIG. 19 is a flowchart showing an example of processing according to the present embodiment.
In step S1902, a user operation (search instruction) is accepted.
In step S1904, the retrieved print job information is extracted. That is, a print job that satisfies a search condition designated for selecting a print job is specified.

  In step S 1906, it is determined whether the print job is already displayed in the time series display area A 840 (or list area 850). If the print job is already displayed in the time series display area A, step S 1916 is performed. Otherwise, the process proceeds to step S1908. That is, when the print job extracted in step S1904 is not displayed in the graphic area 870, processing for determining the enlargement / reduction ratio (processing after step S1908 in “No”) is performed. If the print job extracted in step S1904 is already displayed in the graphic area 870, the enlargement / reduction ratio determination process is not performed (the process of step S1916 in “Yes”).

In step S1908, the start time of the first event of the target print job is extracted.
In step S1910, the end time of the last event of the target print job is extracted.
In step S1912, the enlargement / reduction ratio is calculated so that the start time and the end time are within the display area. That is, when events related to a print job satisfying the search condition are displayed in the graphic area 870 in time series, the time axis is set so that the start time of the first event and the end time of the last event are within the graphic area 870. Determine the scaling factor above.

In step S1914, the target event is displayed in the display area. In other words, control is performed to enlarge and reduce the event sequence related to the print job satisfying the search condition and display it in the graphic area 870 according to the determined enlargement / reduction ratio.
In step S1916, the current enlargement / reduction ratio remains unchanged.
Further, after step S1914 and step S1916, the processing after step S406 in the flowchart shown in the example of FIG. 4 may be performed. However, the target print job is the searched print job.

The processing according to the flowchart illustrated in the example of FIG. 19 may be performed according to the selection method / display position / display range table 2000. That is, the drawing rule determination module 150 extracts the selection method / display position / display range table 2000 in the drawing rule storage module 155, and in accordance with the selection method / display position / display range table 2000, the display position setting module 135, display The range setting module 140 and the enlargement / reduction ratio determination module 145 may perform processing.
FIG. 20 is an explanatory diagram showing an example of the data structure of the selection method / display position / display range table 2000.
The selection method / display position / display range table 2000 includes a print job selection method column 2010, a display position column 2020, and a display range column 2030. The print job selection method column 2010 stores a print job selection method. The display position column 2020 stores the display position. The display range column 2030 stores a display range.

For example, the first row of the selection method / display position / display range table 2000 includes “jump selection to print job hit by print job search” in the print job selection method column 2010 and “event start” in the display position column 2020. “Adjust date and time to display range start date and time”, “Adjust to the range from the start to the end of the selected job” is stored in the display range column 2030, and the second line is “Any from the list” in the print job selection method column 2010 ”,“ Match event start date and time with display range start date ”in the display position column 2020, and“ do not automatically change display range ”in the display range column 2030.
In the display position column 2020, “the event start date and time is matched with the display range start date and time” is used. However, according to the type of print job, the display position column 720 of the print job type / display position / display range table 700 is used. The display position may be changed.
The first line of the display range column 2030 (“fit to the range from the start to the end of the selected job”) is because when searching for a print job, it is desired to focus on the job as a search result.
The second line of the display range column 2030 (“the display range is not automatically changed”) is because the user wants to check the context of the print job when it is selected from the list.

FIG. 21 is an explanatory diagram showing a display example according to the present embodiment.
The example shown in FIG. 21 shows the case where “XXB” is searched in the search expression reception field 830, and the print job including “XXB” in the print job name is searched, as in the example of FIG. However, it is assumed that the search print job 2110 is not displayed in the list area 850 before the search. That is, it is a case of “No” in step S1906. In this case, the enlargement / reduction processing is performed by shifting the time axis so that the event start point of the search print job 2110 is the left end of the graphic area 870 and the end point is the right end of the graphic area 870. Accordingly, the event content of the search print job 2110 is displayed in an enlarged manner in the entire graphic area 870.

22 and 23 are flowcharts showing processing examples according to the present embodiment.
If a simple reduction is performed when an event of the printing apparatus is displayed in the scroll bar-shaped time-series display area B820, important event information (such as an error) in a short time may be lost. On the other hand, since the reduced display is performed in the first place, not all events may be displayed. Therefore, in this embodiment, the weighting according to the event status is used to suppress the loss of important event information.

In step S2202, the designated display time zone is acquired.
In step S2204, the history information of the print job included in the display time period is extracted. In other words, the print job history information in which the print processing start time or end time is included in the display time zone specified in step S2202 is acquired. The printing process here includes the four events described above.

In step S2206, the ratio of the display time zone to the time series display area B820 is calculated, and the magnification for displaying in the time series display area B820 is obtained. That is, using the history information extracted in step S2204, a plurality of events related to the print job are arranged on one time axis, and a time series display area B820 along the time axis (of course, a scroll bar ( The display magnification is calculated for display within the display time zone (including the inside of 910).
In step S2208, the status of the event in the print job in the display time zone is extracted.

In step S2210, using the event status / display color / weight table 2400, the display color and weight corresponding to the status of the event are extracted. The event status / display color / weight table 2400 is an example of a drawing rule for expressing the event processing time specified by the start time and end time of each event in a rectangle. FIG. 24 is an explanatory diagram showing an example of the data structure of the event status / display color / weight table 2400. The event status / display color / weight table 2400 includes an event status field 2410, a display color field 2420, and a weight field 2430. The event status column 2410 stores an event status. The display color column 2420 stores display colors. The weight column 2430 stores weights. That is, the event status / display color / weight table 2400 is weighted in advance for each event so that more important events are preferentially displayed.
For example, the first row of the event status / display color / weight table 2400 stores “error” in the event status column 2410, “red” in the display color column 2420, and “large” in the weight column 2430, and the second row , “Warning” is stored in the event status column 2410, “yellow” is stored in the display color column 2420, “medium” is stored in the weight column 2430, and “normal” is stored in the event status column 2410 and “normal” is displayed in the display color column 2420. “Green” and “Small” are stored in the weight column 2430. Here, “normal” includes reception processing, intermediate form generation processing, image generation processing, and printing processing.
In the event status / display color / weight table 2400 shown in the example of FIG. 24, an error state heavier than a normal state is preferentially displayed. For example, when the weight is “large” or “medium”, even if the reduction result is less than one pixel, drawing is performed with a width of one pixel. When the weight is “small”, when the reduction result is less than one pixel, no display is performed. Therefore, in the time series display area B820, an event whose status is “error” is always displayed even if the event period is short. On the other hand, an event having a status of “warning” or “normal” may not be displayed in the time-series display area B820 if the event period is short. As described above, when the compressed display is performed on the time axis, it is possible to display without missing the status that the user should pay attention to.

In step S2212, it is determined whether or not the weight is “large”. If it is “large”, the process proceeds to step S2214; otherwise, the process proceeds to step S2218.
In step S2214, it is determined whether the display width is less than the minimum width. If the display width is less than the minimum width, the process proceeds to step S2216; otherwise, the process proceeds to step S2218.
In step S2216, the display width is set to the minimum width. Specifically, the display width is one pixel.

In step S2218, it is determined whether or not there is a gap between events. If there is no gap, the process proceeds to step S2220. Otherwise, the process proceeds to step S2228.
In step S2220, it is determined whether or not the statuses of the adjacent events are the same. If they are the same, the process proceeds to step S2222; otherwise, the process proceeds to step S2224.
In step S2222, adjacent events are set as one event. In other words, when the gap between adjacent events across the gap is reduced by reducing the magnification calculated in step S2206 and the status information types of the adjacent events are the same, the adjacent events are identified. Will be drawn as one event.

In step S2224, priority is given to reducing the one where the weight of an adjacent event is smaller. In other words, when the types of status information of events that are adjacent without a gap are different, the event having a smaller weight is prioritized and reduced at the magnification calculated in step S2206. Here, “weighted event” refers to a case where the weights of adjacent events are compared. In the case of “large” and “medium”, “medium”, and “large” and “small” In the case of “small”, “medium”, and “small”, it is “small”.
In step S2226, the display width of the event is determined by allocating the surplus display width to the larger weight of the adjacent event due to the reduction.
In step S2228, the time series display area B820 is drawn. In other words, the rectangle representing each event is reduced in the time axis direction and drawn in the time-series display area B820 according to the weighting of the event at the magnification calculated in step S2206.

FIG. 25 is an explanatory diagram showing a display example according to the present embodiment.
Events in the printing apparatus within the period specified in the target period setting field 810 are graphically displayed on the time series display area B820. The display time zone 2510 designated by the user's operation is enlarged and displayed in the printing apparatus processing graphic area 872. In the printing apparatus processing graphic area 872, events in the printing apparatus displayed in the printing apparatus name display area 852 are displayed. It can be said that the printing apparatus processing graphic area 872 is an aggregation (summarization) of events of each print job in the graphic area 870 after the second line.
Thus, if simple reduction is performed in the display in the time-series display area B820, important event information (such as an error) in a short time may be lost.
In the present embodiment, according to the event status weight defined in the event status / display color / weight table 2400, an event having a large weight is prevented from being lost.

FIG. 26 is an explanatory diagram showing a display example according to the present embodiment. The example shown in FIG. 26 displays the relationship between the display time zone 2510 shown in the example of FIG. 25 and the printing apparatus processing graphic area 872 in an easy-to-understand manner.
In the printing apparatus processing graphic area 872, an event (normal) 2610, a gap 2612, an event (error) 2614, a gap 2616, an event (normal) 2618, a gap 2620, and an event (normal) 2622 are displayed.
In the display time zone 2510, an event (normal) 2630, an event (error) 2634, an event (normal) 2638, a gap 2640, and an event (normal) 2642 are displayed. Here, event (normal) 2630 is event (normal) 2610, event (error) 2634 is event (error) 2614, event (normal) 2638 is event (normal) 2618, gap 2640 is gap 2620, event (normal) 2642 Corresponds to the event (normal) 2622. Then, the gap 2612 and the gap 2616 are eliminated by the processing of the flowcharts shown in the examples of FIGS. However, the event (normal) 2610 and the event (error) 2614 that are adjacent to each other due to the absence of the gap 2612 have different statuses, and the weight of the event (normal) 2610 is small. Reduced). Then, in the width when the event (normal) 2610, the gap 2612, and the event (error) 2614 are reduced as a whole, the width obtained by subtracting the reduced width of the event (normal) 2610 is the width of the event (error) 2634. To do. That is, the calculation is performed so that the event (error) 2634 corresponding to the event (error) 2614 can be widened. Similarly, an event (error) 2614 and an event (normal) 2618 that are adjacent to each other due to the absence of the gap 2616 have different statuses, and the weight of the event (normal) 2618 is small, so that it is preferentially reduced ( Reduce first). The remaining width obtained by subtracting the reduced width of the event (normal) 2618 from the width when the event (error) 2614, the gap 2616, and the event (normal) 2618 are reduced as a whole is the width of the event (error) 2634. To do. That is, the calculation is performed so that the event (error) 2634 corresponding to the event (error) 2614 can be widened.

FIG. 27 is an explanatory diagram showing a display example according to the present embodiment. FIG. 27 shows an example different from the example of FIG. The display time zone 2750 is on the time-series display area B820 and corresponds to the display time zone 2510 described above.
The event (normal) 2710 has a weight of “small” and, as a result of the reduction, the display width has become less than the minimum width, and thus is not displayed in the display time zone 2750.
The event (error) 2714 is displayed as an event (error) 2754 in the display time zone 2750 with the minimum width because the display width becomes less than the minimum width as a result of the reduction, but because of the weight “large”.
As a result of the reduction, the display width of the gap 2720 becomes less than the minimum width, and since the event (normal) 2718 and the event (normal) 2722 have the same event status, they are displayed as one event (normal) 2758 within the display time zone 2750. doing.
As a result of the reduction, the display width of the gap 2728 becomes less than the minimum width, and the event (warning) 2726 and the event (normal) 2730 have different event statuses. 2770, and the remaining display width is an event (warning) 2766 indicating an event (warning) 2726.
Here, the “remaining display width” is calculated as follows.
(1) The display width in the display time zone 2750 indicating the period of the event (warning) 2726, the gap 2728, and the event (normal) 2730 is calculated. Specifically, this is the display width when the time zone from the start of the event (warning) 2726 to the last time of the event (normal) 2730 is allocated within the display time zone 2750.
(2) Display width of event (warning) 2766 indicating event (warning) 2726 is obtained by subtracting reduced event (normal) 2730 and reduced gap 2728 (substantially 0) from the display width calculated in (1). And Note that the priority display can be realized by controlling the order of division because the value after the decimal point is rounded down in the division in the reduction. That is, since the one with the smaller weight (event (normal) 2730) is reduced first, the display width of the one with the larger weight (event (warning) 2726) is likely to increase due to the effect of rounding down the decimal point. Here, “the display width is increased” indicates that the display width with a larger weight is larger than when the display width with a larger weight is simply reduced.
