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 for a configuration example of the present embodiment.
The module generally refers to parts such as software (computer program) and hardware that can be logically separated. Therefore, the module in this embodiment refers not only to the module in the computer program but also to the module in the hardware configuration. Therefore, in this embodiment, a computer program for functioning as those modules (a program for causing the computer to execute each procedure, a program for causing the computer to function as each means, and each function for the computer). It also serves as an explanation of the program), system and method for realizing the above. However, for convenience of explanation, "remember", "remember", and equivalent words are used, but these words are stored in a storage device or stored when the embodiment is a computer program. It means that it is controlled to be stored in the device. Further, the modules may have a one-to-one correspondence with each other, but in mounting, one module may be configured by one program, a plurality of modules may be configured by one program, and conversely, one module may be configured. May be composed of a plurality of programs. Further, the plurality of modules may be executed by one computer, or one module may be executed by a plurality of computers by a computer in a distributed or parallel environment. It should be noted that one module may include another module. In addition, hereinafter, "connection" is used not only for physical connection but also for logical connection (data transfer, instruction, reference relationship between data, etc.). "Predetermined" means that it is determined before the target process, not only before the process according to the present embodiment starts, but also after the process according to the present embodiment starts. However, if it is before the target process, it is used with the intention that it is determined according to the situation / state at that time or according to the situation / state up to that point. When there are a plurality of "predetermined values", they may be different values, or two or more values (including, of course, all values) may be the same. Further, the description "if A, do B" is used to mean "determine whether or not it is A, and if it is determined to be A, do B". However, this excludes cases where it is not necessary to determine whether or not it is A. Further, when a thing is listed such as "A, B, C", it is an example list unless otherwise specified, and includes a case where only one of them is selected (for example, only A).
In addition, a system or device is configured by connecting a plurality of computers, hardware, devices, etc. by communication means such as a network (including a one-to-one correspondence communication connection), and one computer, hardware, device, etc. It also includes cases where it is realized by such as. "Device" and "system" are used as synonymous terms. Of course, the "system" does not include anything that is nothing more than a social "mechanism" (social system) that is an artificial arrangement.
In addition, for each process by each module or when multiple processes are performed in the module, the target information is read from the storage device, and after the processes are performed, the process results are written to the storage device. be. Therefore, the description of reading from the storage device before processing and writing to the storage device after processing may be omitted. The storage device here 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 the operation state information (may include future prediction information) of the printing device recorded as the history of the printing process on the time axis. As shown in the example of FIG. 1, it has 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.

The display device 100 visually displays the print history (process history) of the print job in chronological order. It has a so-called timeline function. Specifically, set the start date and time (in the case of date and time, the year, month, day, hour, minute, second, second or less, or a combination thereof) and the end date and time of the print history of the print job. , The print job event that occurred during that time, and the status of the printing device are visualized and displayed in chronological order.
Further, the display device 100 can display a list of print jobs processed within an arbitrary time range between the start date and time and the end date and time. Then, the time range can be arbitrarily changed according to a user-specified operation. For example, as an example in which the time range progresses 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 and time while keeping the specified time range. That is, when the start date and time are changed, the time range is fixed, so the end date and time are also changed when the start date and time are changed. For example, as will be described later, the history display time range is changed by moving the scroll bar (display time zone) 910 shown in FIG. 9 left and right (slide).
Further, in the display device 100, the target to be displayed in time series displays not only the history past the current time but also the prediction information future 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 is the past history, and the right side of the current time display line 1030 is the future prediction.

The reception module 105 is connected to the print job identification module 115. The reception module 105 accepts user operations. The operation may be an operation received from the user terminal 280 described later using the example of FIG. 2, or may be an operation received by the user interface (keyboard, mouse, touch panel, etc.) provided in the display device 100. .. As a user operation, for example, a print job selected by the user is accepted. There may be a plurality of selected print jobs.
The transmission module 110 is connected to the time chart display module 125. The transmission module 110 transmits the processing result of 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) provided 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 identifies 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, a mouse, a touch panel, or the like.
Further, the print job specifying module 115 identifies a print job that satisfies the search condition specified for selecting a print job. The selection after the search here includes not only those selected by the user's operation using the keyboard, mouse, touch panel, etc., but also the search results when the print job is searched. That is, the search result itself (or the search instruction) may correspond to the selection operation even if there is no explicit user selection operation.
Further, the print job specifying module 115 acquires the history information of the print job including the start time or the end time of the print process within the designated period from the print job information storage module 120.
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 history of print jobs. For example, the print job information table 500 and the print job (event) log table 600, which will be described later, are stored.

The time chart display module 125 has a setting module 130, a drawing rule storage module 155, a display control module 160, and a drawing module 165, and is connected to a transmission module 110 and a print job identification module 115. The time chart display module 125 is a module for realizing the timeline function, and graphically displays (display control) the history of print jobs and the prediction of the status of print jobs 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 displaying events related to the target print job in the display area in chronological order according to the attributes of the print job specified by the print job identification module 115. And / or set the end point. Here, the "target print job" is a print job specified by the print job specification module 115. The status of the print job is included as the "attribute of the print job". Specifically, it refers to the current processing status (status), and includes normal termination, reserved job (print job for which processing has not started), error occurrence, and the like. The "event related to the print job" indicates the processing content (also referred to as a process) from the acceptance to the end of the print job, and specifically, reception, first-stage image generation processing, and second-stage image. There are generation processing, printing, etc. Further, the state of those processes (specifically, normal end, reserved job, error occurrence, etc.) may be included in correspondence with the process.
The "starting point on the time axis" is the position indicating that the processing has started when the processing is graphically represented on the time axis. Specifically, when the past is on the left and the future is on the right on the time axis. The position of the left end of the process.
The "end point on the time axis" is a position indicating that the processing has been completed when the processing is graphically represented on the time axis. Specifically, when the past is on the left and the future is on the right on the time axis. The position of the right end 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 displaying events (processes) executed by each print job in chronological order. Then, in the list area, an identifier (job ID, job name, etc.) that uniquely identifies each job may be displayed. Of course, the events of the print job displayed in the list area and the print job displayed in the graphical area correspond to each other.
Further, it is desirable that the list area is sorted in ascending or descending order according to the start time or end time of each print job. This is because the event is also displayed for the print job processed / processed before and after on the time axis of the selected print job, and especially for the print job in which the error occurred, if the cause is the print job before and after. Because there is.

Further, the display position setting module 135 shifts the time axis so that the start time of the print job specified by the print job identification module 115 becomes the left end of the display area when the attribute of the print job ends normally. You may.
Further, when the attribute of the print job 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 identification module 115 is at the right end of the display area. You may.
Further, when the attribute of the print job is an error, the display position setting module 135 sets the time axis so that the start time of the print job specified by the print job identification module 115 is between the left end and the right end of the display area. You may try to shift. Here, the time axis is shifted so that it is displayed in the substantially center of the display area (for example, so as to fit within a predetermined section from the center) as "between the left end and the right end of the display area".

The display range setting module 140 sets the date and time at the left end and the date and time at the right end in the display area according to the operation of the user. For example, the operation for the scroll bar (display time zone) 910 shown in FIG. 9 described later corresponds to this. That is, by changing the size (length) of the scroll bar (display time zone) 910, the history display time range (length of the period) in the display area is specified. Then, by moving the scroll bar (display time zone) 910 on the time-series display area B820, the start point and the end point in the display area are designated.

The enlargement / reduction ratio determination module 145 determines the reduction ratio or the enlargement ratio 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 uses the print job processed before the print job A at the start of the event and the print job processed after the print job A. The reduction ratio or enlargement ratio on the time axis is determined so that the end of the event of 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, the enlargement processing is performed.
Further, the enlargement / reduction ratio determination module 145 displays the start time of the first event and the end time of the last event when displaying the events related to the print jobs satisfying the search conditions in the display area in chronological order. Determine the scaling ratio on the time axis so that it fits in the area.
Further, the enlargement / reduction ratio determination module 145 may determine the enlargement / reduction ratio when the print job specified by the print job identification module 115 is not displayed in the display area.

Further, the enlargement / reduction ratio determination module 145 may not perform the enlargement / reduction ratio determination processing when the print job specified by the print job identification module 115 is displayed in the display area.
In this case, when the print job specified by the print job identification module 115 is displayed in the display area, the display position setting module 135 sets the 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 side by side in the display area.

Further, the enlargement / reduction ratio determination module 145 arranges a plurality of events related to the print job on one time axis by using the history information acquired by the print job identification module 115, and displays a display area along the time axis. Calculate the magnification for displaying in.

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 by using the print job history information acquired by the print job identification module 115, and is specified by the start time and end time of each event. The 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, the print job type / display position / display range table 700, the selection method / display position / display range table 2000, the event status / display color / weight table 2400, etc., which will be described later, are stored.

The display control module 160 displays the event related to the target print job and the event before and / or after the print job in the display area according to the start point and / or the end point set by the display position setting module 135. Control the display position of each event related to the print job.
Further, the display control module 160 may be controlled to display the event related to the print job without enlarging or reducing the image.
Further, the display control module 160 controls to enlarge / reduce the event sequence related to the print job satisfying the search condition and display it in the display area according to the enlargement / reduction ratio determined by the enlargement / reduction ratio determination module 145.
Further, the display control module 160 has a magnification calculated by the enlargement / reduction ratio determination module 145, and a rectangle representing each event is weighted according to the type of status information indicating the processing result of each event on the time axis. Reduce in direction and draw in the display area. The "weighting" includes the concept of priority. When the maximum weight is given, it means that the priority is the highest. A low weight means a low priority.
Further, the display control module 160 may control drawing according to the drawing rule determined by the drawing rule determination module 150. Further, the event to which the maximum weighting is given in the drawing rule may not be reduced to a size 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 to a size that is the minimum drawing unit or less" means that, for example, even if the reduced result is less than one pixel, drawing is performed with one pixel width.
Further, the display control module 160 reduces the gap between adjacent events across the gap by the magnification calculated by the enlargement / reduction ratio determination module 145, and the status of the adjacent event disappears. If the types of information are the same, adjacent events may be controlled to be drawn as one event.
Further, when the types of status information of adjacent events are different without a gap, the display control module 160 gives priority to an event with a small weight and controls the event so as to reduce the image by the magnification calculated by the enlargement / reduction rate determination module 145. May be good.
The drawing module 165 performs display processing on the display device according to the 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 morphogenesis generation module 175 performs the first stage image generation processing. Specifically, intermediate form document data is generated from the document to be printed by the print job. Here, the intermediate form document data has a data structure at a stage before the generation of print data, and it is difficult to directly generate print data 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. Then, it is easier to generate the print data from the intermediate form document data than to generate the print data directly from the 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, printable 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.

FIG. 6 is an explanatory diagram showing an example of a 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 column 604 has a reception column 606, an intermediate form generation column 616, an image generation column 626, and a print column 636. This corresponds to four events in the printing process. Specifically, (1) print job reception processing, (2) intermediate form generation processing (processing by intermediate form generation module 175), (3) image generation processing (processing by image generation module 180), (4) printing. There is a process (process by the print module 185). Each has event ID, start date and time, end date and time, and result information. That is, the reception column 606 has an event ID column 608, a start date and time column 610, an end date and time column 612, and a result column 614, and the intermediate form generation column 616 has an event ID column 618, a start date and time column 620, and an end date and time. The column 622 and the result column 624 are provided, the image generation column 626 has an event ID column 628, a start date and time column 630, an end date and time column 632, and a result column 634, and the print column 636 is an event ID column. It has 638, a start date and time column 640, an end date and time column 642, and a result column 644.
The print job ID column 602 stores the print job ID. The event column 604 stores information (history information) related to the event. The reception column 606 stores the reception event. The event ID column 608 stores information (event ID) for uniquely identifying an event in the present embodiment. The start date / time column 610 stores the start date / time. The end date and time column 612 stores the end date and time. The result column 614 stores the result. The intermediate form generation column 616 stores the intermediate form generation event. The event ID column 618 stores the event ID. The start date / time column 620 stores the start date / time. The end date and time column 622 stores the end date and time. The result column 624 stores the result. The image generation column 626 stores an image generation event. The event ID column 628 stores the event ID.

The end date and time column 642 stores the end date and time. The result column 644 stores the result.
For example, the first row of the print job (event) log table 600 is "1" in the print job ID column 602, "E-001" in the event ID column 608 for the receive column 606, and "XXX / XX" in the start date and time column 610. / XX / XX / XX / XX "," XXX / XX / XX / XX / XX / XX "in the end date and time column 612," normal end "in the result column 614, and" normal end "in the intermediate form generation column 616" in the event ID column 618. "E-002", "XXX / XX / XX / XX / XX / XX" in the start date / time column 620, "XXX / 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 for the image generation column 626, "XXX / XX / XX / XX / XX / XX" in the start date / time column 630, and "XXX / XX / XX / XX" in the end date / time column 632. / XX / XX "," normal end "in the result column 634," E-004 "in the event ID column 638 for the print column 636," XXX / XX / XX / XX / XX / XX "in the start date and time column 640, end "XXX / XX / XX / XX / XX / XX" is stored in the date and time column 642, and "error occurrence (paper jam)" is stored in the result column 644. That is, print job: 1 indicates that the reception process, the intermediate form generation process, and the image generation process were normally completed, but an error (paper jam) occurred in the final print process.
The second row of the print job (event) log table 600 is "2" in the print job ID column 602, "E-021" in the event ID column 608 for the receive column 606, and "XXX / XX / XX" in the start date and time column 610. / XX / XX / XX "," XXX / XX / XX / XX / XX / XX "in the end date and 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 "," XXX / XX / XX / XX / XX / XX "in the start date and time column 620," XXX / XX / XX / XX / XX / XX "in the end date and time column 622," normal end "in the result column 624, About the image generation column 626 "E-023" in the event ID column 628, "XXX / XX / XX / XX / XX / XX" in the start date and time column 630, and "XXX / XX / XX / XX / XX" in the end date and time column 632. / 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, blank (null) in the end date / time column 642, result column. "Processing schedule (waiting for print)" is stored in 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 final print process is unprocessed (waiting for printing). The start date and time and the end date and time of the 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 attributes of the print job are determined, and if "normal end", the process proceeds to step S408, if "reservation", the process proceeds to step S412, and if "error occurs", the process proceeds to step S416. For example, the determination may be made using the information in the result column 644 (or the result column 614, the result column 624, and the result column 634 other than the normal end) 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 to the left end of the display area. For example, the 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, according to the attributes of the specified print job, the starting point on the time axis when the events related to the print job are arranged in chronological order and displayed in the display area is set.

In step S410, the current enlargement / reduction ratio (magnification) setting is inherited, and the process proceeds to step S424. That is, the enlargement / reduction is not performed. Therefore, since the starting point and the enlargement / reduction ratio on the time axis are determined, in this process, when the events related to the print job are displayed in the display area in chronological order according to the attributes of the specified print job. The end point on the time axis of is set. Further, 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 the enlargement / reduction is performed each time a print job is selected, it may not be clear whether the target print job is the same or not, and the user may be confused. Therefore, the enlargement / reduction is not performed so that the user does not get confused. The same applies to the processes in steps S414 and 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 the information (number of pages, etc.), schedule (printing order), printing speed of the printing device, etc. in the print job. In this process, according to the attributes of the specified print job, the end point on the time axis when the events related to the print job are arranged in chronological order and displayed in the display area is set.
In step S414, the current enlargement / reduction ratio (magnification) setting is inherited, and the process proceeds to step S424. Therefore, since the end point and the enlargement / reduction ratio on the time axis are determined, in this process, when the events related to the print job are displayed in the display area in chronological order according to the attributes of the specified print job. The starting point on the time axis of is set. Further, since the attribute of the print job 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 in the display area (between the left end and the right end). For example, the 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, according to the attributes of the specified print job, the starting point on the time axis when the events related to the print job are arranged in chronological order and displayed in the display area is set. Then, since the attribute of the print job is the case where an error occurs, 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 with the center of the graphic area 870, or the entire print job before and after the target print job may be moved so as to fit in the graphic area 870. You may.

In step S418, at the current magnification, "at the start of the event of the print job processed before the target print job" and "at the end of the event of the print job processed after the target print job" are set. It is determined whether or not it fits in the display area, and if it fits, the process proceeds to step S422, and if it does not fit, the process proceeds to step S420.

In step S420, at least at the start of the event of the print job processed before (including the end of course), and at the end of the event of the print job processed after (of course, at the start). The magnification is set so that (including) is within the display area, and the process proceeds to step S424. In this process, since the attribute of the print job is an error, the print job processed before the print job (print job in which the error occurred) starts the event and the print job (print in which the error occurs). The print job processed after the job) will be reduced or enlarged on the time axis so that the end of the event will fit within the display area.
It should be noted that the enlargement / reduction (magnification) is changed by the print job that causes the error or the influence of the error occurrence rather than the target print job (print job in which the error occurs). This is because it is important to know the print job. That is, it is enlarged / reduced 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 inherited, and the process proceeds to step S424.
In step S424, the inside of the display area is drawn according to the set display position and magnification. That is, the 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 according to the set start point and / or end point. To control.

The process according to the flowchart shown in the example of FIG. 4 may be performed according to 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 the display position setting module 135 according to the print job type / display position / display range table 700. , The display range setting module 140 and the enlargement / reduction ratio determination module 145 may perform the processing.
FIG. 7 is an explanatory diagram showing an example of a data structure of the print job type / display position / display range table 700. The print job type / display position / display range table 700 has 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 the print job. The display position column 720 stores the display position. The display range column 730 stores the display range.

For example, in the first row of the print job type / display position / display range table 700, "process scheduled job (future prediction display job)" is displayed in the print job type column 710, and "event end date / time is displayed in the display position column 720". "Fit to the end date and time (right end of the display area)", "Fit 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. , "Align the event to the center of the display range" in the display position column 720, and "Align the event start date and time of the previous job and the event end date and time of the subsequent job" in the display range column 730, and store it in the third line. In the print job type column 710, "normally completed job", in the display position column 720, "match the event start date and time with the display range start date and time (left end of the display area)", and in the display range column 730, "start job event". To match the range from to the end "is memorized.

The display area will be described with reference to 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.

In the printing device processing graphic area 872, the processing content (event) in the printing device is graphically displayed. For example, the elements (rectangles) indicating "receiving", "intermediate form document data generation", "printing data generation", "printing (printing)", "waiting for user operation", etc. are color-coded. indicate. Further, it may be displayed in different colors according to the result of the processing (normal termination, warning, error, etc.).
From the second line onward of the list area 850, the print job within the period specified by the scroll bar (display time zone) 910 (and if the search expression reception field 830 is used, the search expression reception field 830). Print jobs searched according to the search formula accepted in step 1) are displayed. For example, the print job name, the result, and the like may be displayed in a list.
In the second and subsequent lines of the graphic area 870, the processing contents in the print job are displayed graphically. For example, the elements (rectangles) indicating "receiving", "intermediate form document data generation", "printing data generation", "printing (printing)", "waiting for user operation", etc. are color-coded. indicate. Further, it may be displayed in different colors according to the result of the processing (normal termination, warning, error, etc.).

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.
It 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 print job event and the status of the printing device that occurred during that period are visualized and displayed in chronological order on the screen 800. ..
By operating the target period setting field 810 by the user, it is possible to display a list of print jobs processed within an arbitrary time range between the start date and time and the end date and time in the list area 850. Then, the time range can be arbitrarily changed by the user in the target period setting field 810.
Then, by the user 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 day can be changed while keeping the specified time range. It is possible. The scroll bar (display time zone) 910 will be described in detail later with reference to 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, the 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 of the current time display line 1030 (future prediction display area 1040) shows the future prediction. Of course, for the past from the current time, the print history of the print job may be used. Then, 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 (intermediate form generation module 175, image generation module 180 processing speed), printer printing speed (printing speed of printing module 185), and finishing processing based on print job settings. It may be calculated according to (punch (drilling), document binding (stapler fastening), 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 / black and white printing), 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 device processing graphic area 872) is displayed corresponding to the time zone in which the display time zone 1110 is located. The display time zone 1110 can be changed by the operation of the user.
The time-series display area B820 shows the time axis from 0:00 to 24:00 on March 7, 2017 (Tuesday). That is, the states of the printing apparatus on the start date and the end date are displayed on the time series display area B820.
The display time zone 1110 in the time-series display area B820 specifies the period (30 minutes) from 9:28:49 to 9:58:49 on March 7, 2017 (Tuesday). 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 zone 1110 while observing the state of the printing device on the time series display area B820.
The details of the display time zone 1110 are displayed in the printing apparatus processing graphic area 872. Conversely, a reduced size of the printing device processing graphic area 872 is displayed in the display time zone 1110. Within the printing device processing graphic area 872, there are a printing device display bar 1122, a user operation waiting presentation bar 1124, a printing display bar 1126, and a printing display 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 19:27:09 on March 27, 2017 to 19:45:38 on March 27, 2017.
Here, when the target print job 1210 is selected by the user's operation, it is displayed as shown in the example of FIG. 12 (b). That is, the event of the target print job 1210 is scrolled so as to be the start time of the graphic area 870. Specifically, the inside of the graphic area 870 is displayed with 19:29:25 on March 27, 2017, which is the start of processing of the target print job 1210, as the left end. Of course, the graphic area 870 of other print jobs is also displayed with 19:29:25 on March 27, 2017 at the left end. 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, by selecting the print job, the print job event is scrolled and displayed. It becomes possible to do.

FIG. 13 is an explanatory diagram showing a display example according to the present embodiment.
On the screen 800, the print job can be searched by using the search formula reception field 830. That is, it is possible to search for any parameter (print job name, exit status, etc.) of the print job. In the list area 850, the print job that hits the search is jumped (jump is to make a list including the print job that is the search result) and displayed. Scrolls 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 for in the search formula reception field 830 (see FIG. 13 (c)) of FIG. 13 (a), 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 which 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. I'm scrolling.
Note that the display position of the event related to the search print job 1310 may be changed according to the attributes of the search print job 1310 according to the flowchart shown in the example of FIG.
If there are multiple print jobs that are hit as search results, press the triangle buttons (right-pointing triangle button and left-pointing triangle button) in the search formula reception field 830 shown in the example of FIG. 13 (c) to execute the next search print job. It may be displayed.

FIG. 14 is an explanatory diagram showing a display example of comparison.
When the origin of the event of the selected print job is always aligned with the left end of the graphic area 870 (that is, when the present embodiment is not adopted), the selected print is selected regardless of the attributes of the print job. The print job that precedes the job will not be displayed in the graphic area 870. Specifically, as shown in the example of FIG. 14, when a print job in which an error occurs in the target print job 1410 is selected, the event of the previous print job (one lower in the list area 850) is displayed in the display range. Be outside.
However, in the case of a print job to be processed (print job predicted in the future), the end date and time is more important than the event start date and time, so the end date and time should also be displayed in the graphic area 870. Further, if it is an error job, there is a desire to grasp the status of the print job before and after the error occurs.

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

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

FIG. 17 is an explanatory diagram showing a display example of comparison.
When the origin of the event of the selected print job is always aligned with the left end of the graphic area 870 (that is, when the present embodiment is not adopted), printing in the list area 850 is performed regardless of the attributes of the print job. When job 1610 is selected, as shown in the example of FIG. 17, the pre-error event group 1630 of the print job before that (one below 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 the present 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 below in the list area 850). The starting point of the pre-error event group 1630 (at the start of the event) is the left end of the graphic area 870, and the post-error event group 1640 of the print job 1840 after the error occurs after the print job 1610 (one level higher in the list area 850). The slide process and the enlargement / reduction process are performed so that the end point (at the end of the event) of is the right end of the graphic area 870.

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

In step S1906, it is determined whether or not the print job is already displayed in the time-series display area A840 (or the list area 850), and in the case of the print job already displayed in the time-series display area A, step S1916. In other cases, the process proceeds to step S1908. That is, when the print job extracted in step S1904 is not displayed in the graphic area 870, the process of determining the enlargement / reduction ratio (the process 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 (process in 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 fit within the display area. That is, when the events related to the print jobs satisfying the search conditions are displayed in the graphic area 870 in chronological order, the time axis is set so that the start time of the first event and the end time of the last event fit in the graphic area 870. Determine the scaling factor above.

In step S1914, the target event is displayed in the display area. That is, control is performed so that the event column related to the print job satisfying the search condition is enlarged or reduced and displayed in the graphic area 870 according to the determined enlargement / reduction ratio.
In step S1916, the current enlargement / reduction ratio is maintained.
Further, after step S1914 and step S1916, the processing after step S406 of the flowchart shown in the example of FIG. 4 may be performed. However, the target print job is the searched print job.

The process according to the flowchart shown in the example of FIG. 19 may follow the selection method, display position, and 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 the display position setting module 135 and the display according to the selection method / display position / display range table 2000. The range setting module 140 and the enlargement / reduction ratio determination module 145 may perform the processing.
FIG. 20 is an explanatory diagram showing an example of a data structure of the selection method, display position, and display range table 2000.
The selection method / display position / display range table 2000 has 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 the display range.

For example, in the first row of the selection method / display position / display range table 2000, "jump selection to a print job hit by a print job search" is displayed in the print job selection method column 2010, and "event start" is displayed in the display position column 2020. "Adjust the date and time to the start date and time of the display range" and "Adjust to the range from the start to the end of the selected job" are stored in the display range column 2030, and the second line is "Arbitrary from the list" in the print job selection method column 2010. "Select a print job", "Adjust the event start date and time to the display range start date and time" in the display position column 2020, and "Do not automatically change the display range" in the display range column 2030.
In the display position column 2020, "match the event start date and time with the display range start date and time" was set, but using the display position column 720 of the print job type / display position / display range table 700, depending on the type of print job, 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 due to the fact that when searching for a print job, it is desired to focus on the job of the search result.
The second line of the display range column 2030 (“The display range is not automatically changed”) is due to the fact that when a print job is selected from the list display, the context is also confirmed.

FIG. 21 is an explanatory diagram showing a display example according to the present embodiment.
The example shown in FIG. 21 shows a case where a print job including "XXB" in the print job name is searched when "XXB" is searched in the search formula reception field 830, 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 the case of "No" in step S1906. In this case, the time axis is shifted so that the start point of the event of the search print job 2110 is at the left end of the graphic area 870 and the end point is at the right end of the graphic area 870, and enlargement / reduction processing is performed. Therefore, the content of the event of the search print job 2110 is enlarged and displayed in the entire graphic area 870.

22 and 23 are flowcharts showing processing examples according to the present embodiment.
When displaying the events of the printing device in the scroll bar-shaped time-series display area B820, if a simple reduction is performed, important event information (errors, etc.) for a short time may be missing. On the other hand, since the display is reduced in the first place, it may not be possible to display all the events. Therefore, in the present embodiment, weights according to the event status are used to prevent 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 zone is extracted. That is, the history information of the print job whose start time or end time of the print process is included in the display time zone specified in step S2202 is acquired. The printing process here includes the above-mentioned four events.

In step S2206, the ratio occupied by the display time zone to the time-series display area B820 is calculated, and the magnification when 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 the time-series display area B820 along the time axis (of course, the scroll bar (scroll bar (of course,)). Calculate the magnification for displaying within the display time zone) (including within 910).
In step S2208, the status of the event in the print job in the display time zone is extracted.

In step S2210, the event status / display color / weight table 2400 is used to extract the display color and weight corresponding to the status of the event. 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 as a rectangle. FIG. 24 is an explanatory diagram showing an example of a data structure of the event status / display color / weight table 2400. The event status / display color / weight table 2400 has an event status column 2410, a display color column 2420, and a weight column 2430. The event status column 2410 stores the event status. The display color column 2420 stores the display color. The weight column 2430 stores the weight. 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, in the first row of the event status / display color / weight table 2400, "error" is stored in the event status column 2410, "red" is stored in the display color column 2420, and "large" is stored in the weight column 2430. , "Warning" in the event status column 2410, "yellow" in the display color column 2420, "medium" in the weight column 2430, and the third line is "normal" in the event status column 2410 and "normal" in the display color column 2420. "Green" and "small" are stored in the weight column 2430. The term "normal" here 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, the error state heavier than the normal state is preferentially displayed. For example, when the weights are "large" and "medium", even if the reduced result is less than one pixel, the drawing is performed with one pixel width. If the weight is "small" and the reduced result is less than one pixel, it will not be displayed. Therefore, in the time-series display area B820, the event whose status is "error" is always displayed even if the event period is short. On the other hand, an event whose status is "warning" or "normal" may not be displayed in the time series display area B820 if the event period is short. In this way, in the case of compressed display on the time axis, it is possible to display the status that the user should pay attention to without missing.

In step S2212, it is determined whether or not the weight is "large", and if it is "large", the process proceeds to step S2214, and if not, the process proceeds to step S2218.
In step S2214, it is determined whether or not the display width is less than the minimum width, and if it is less than the minimum width, the process proceeds to step S2216, and if not, 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 the events, and if there is no gap, the process proceeds to step S2220, and if not, the process proceeds to step S2228.
In step S2220, it is determined whether or not the statuses of adjacent events are the same, and if they are the same, the process proceeds to step S2222, and if not, the process proceeds to step S2224.
In step S2222, adjacent events are regarded as one event. That is, when the gap between adjacent events across the gap is reduced by the magnification calculated in step S2206 and the gap disappears, if the types of status information of the adjacent events are the same, one adjacent event is selected. It will be drawn as one event.

In step S2224, the one with the smaller weight of the adjacent event is preferentially reduced. That is, when the types of status information of adjacent events are different without a gap, the event with the smaller weighting is prioritized and reduced by the magnification calculated in step S2206. Here, the "event with a small weight" is a case where the weights of adjacent events are compared, and when it is "large" and "medium", it is "medium", and when it is "large" and "small", it is. When it is "small", "medium" and "small", it is "small".
In step S2226, the surplus display width due to the reduction is allocated to the one with the larger weight of the adjacent event, and the display width of the event is determined.
In step S2228, the inside of the time series display area B820 is drawn. That is, at the magnification calculated in step S2206, the rectangle representing each event is reduced in the time axis direction according to the weighting of the event and drawn in the time series display area B820.

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 device processing graphic area 872. The printing device processing graphic area 872 displays an event in the printing device displayed in the printing device name display area 852. It can be said that the printing device processing graphic area 872 is a collection (summarized) of the events of each print job from the second line onward in the graphic area 870.
As described above, if the display in the time-series display area B820 is simply reduced, important event information (error, etc.) for a short time may be missing.
In the present embodiment, according to the weight of the event status defined in the event status / display color / weight table 2400, the event having a large weight is prevented from being omitted.

FIG. 26 is an explanatory diagram showing a display example according to the present embodiment. The example shown in FIG. 26 clearly 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 the printing device 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, and event (normal) 2642. Corresponds to 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. 22 and 23. However, the event (normal) 2610 and the event (error) 2614, which are adjacent to each other due to the disappearance of the gap 2612, have different statuses, and the weight of the event (normal) 2610 is small, so that the event (normal) 2610 is preferentially reduced (first). Reduce to). Then, in the width when the entire event (normal) 2610, gap 2612, and event (error) 2614 are reduced, the remaining width obtained by subtracting the reduced width of the event (normal) 2610 is defined as the width of the event (error) 2634. do. That is, the calculation is made so that the width of the event (error) 2634 corresponding to the event (error) 2614 can be widened. Similarly, the event (error) 2614 and the event (normal) 2618 that are adjacent to each other due to the disappearance of the gap 2616 have different statuses, and the weight of the event (normal) 2618 is small, so that the event (normal) 2618 is preferentially reduced (reduced). Reduce first). Then, the remaining width obtained by subtracting the reduced width of the event (normal) 2618 from the width when the entire event (error) 2614, gap 2616, and event (normal) 2618 is reduced is defined as the width of the event (error) 2634. do. That is, the calculation is made so that the width of 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. 26. The display time zone 2750 is on the time-series display area B820 and corresponds to the above-mentioned display time zone 2510.
The event (normal) 2710 has a weight of "small" and is not displayed in the display time zone 2750 because the display width is less than the minimum width as a result of reduction.
The event (error) 2714 has a display width smaller than the minimum width as a result of reduction, but is displayed as an event (error) 2754 within the display time zone 2750 with the minimum width because the weight is "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 in the display time zone 2750. doing.
As a result of the reduction, the display width of the gap 2728 is smaller than the minimum width, and since the event (warning) 2726 and the event (normal) 2730 have different event statuses, the event (normal) 2730 is preferentially reduced to reduce the event (normal). ) 2770, and the surplus display width is the event (warning) 2766 indicating the event (warning) 2726.
Here, the "surplus display width" is calculated as follows.
(1) The display width within the display time zone 2750 indicating the combined period of the event (warning) 2726, the gap 2728, and the event (normal) 2730 is calculated. Specifically, it is a display width when the time zone from the start of the event (warning) 2726 to the final time of the event (normal) 2730 is assigned within the display time zone 2750.
(2) The display width of the event (warning) 2766 indicating the event (warning) 2726 is the display width obtained by subtracting the reduced event (normal) 2730 and the reduced gap 2728 (effectively 0) from the display width calculated in (1). And. By controlling the order of division, priority display can be realized because the value after the decimal point is rounded down in the division in reduction. That is, since the one with the smaller weight (event (normal) 2730) is reduced first, there is a high possibility that the display width of the one with the larger weight (event (warning) 2726) will be larger due to the effect of devaluation after the decimal point. Here, "the display width becomes larger" means that the display width with the larger weight becomes larger when the surplus display width is used than when the display width is simply reduced.
