Description

  The present invention relates to an image forming apparatus and an image forming system, and more particularly, to an image forming apparatus and an image forming system that can cancel a print job.

Conventionally, a method for canceling a specific print job after a print job is reserved and registered in a printer or a copier is known (Patent Document 1). In this method, an identifier of a print job that has been registered for reservation is displayed on the display means, and the print job to be canceled is specified by inputting the identifier.
JP-A-10-233862

  However, the technique described in Patent Document 1 has a problem that when a plurality of print jobs are canceled, it is necessary to input identifiers of all print jobs to be canceled, and the operation procedure becomes complicated.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus and an image forming system capable of canceling a print job without performing a complicated operation.

  In order to achieve the above object, an image forming apparatus according to the present invention includes a job storage unit that stores a print job for performing image formation based on input print data, and a print stored in the job storage unit. An image forming unit that forms an image on a recording medium based on the print data, a condition setting unit that sets a cancel condition for a print job to be canceled, and the image forming unit are executed by executing the job. A canceling unit that cancels from the job storage unit a print job that is not yet a print job or is being executed, and that matches the canceling condition set by the condition setting unit.

  According to the image forming apparatus of the present invention, a print job for performing image formation based on input print data is stored in the job storage unit, and the print job stored in the job storage unit is stored by the image forming unit. By executing, an image is formed on the recording medium based on the print data.

  Here, when the cancel condition regarding the print job to be canceled is set by the condition setting means, the cancel job is a print job that has not been executed by the image forming means or is being executed, and the condition setting means A print job that matches the set cancellation condition is canceled from the job storage unit.

  Therefore, since the cancel condition for the cancel target print job is set and the print job that matches the cancel condition is cancelled, even if a plurality of print jobs are cancelled, the print job can be canceled without performing a complicated operation. .

  The image forming apparatus according to the present invention further includes a condition storage unit that stores the cancellation condition set by the condition setting unit, and the cancellation unit performs a print job for performing image formation based on the input print data. However, if the cancellation condition stored in the condition storage means is met, this print job can be canceled from the job recording means. As a result, a print job that matches a preset cancellation condition can be canceled, so that the print job can be canceled without canceling the newly input print job.

  The image forming apparatus according to the present invention further includes a registration unit that registers job information indicating a print job that has not been executed by the image forming unit, and the image forming unit performs the print job in the order registered in the registration unit. The cancel unit forms an image on the recording medium based on the print data, and the cancel unit cancels the job information indicating the print job from the registration unit when canceling the print job not executed by the image forming unit. The print job can be canceled from the job storage means.

  The cancellation condition may be a condition related to at least one of user identification information, host computer identification information, and a print data file name. Accordingly, a plurality of print jobs having the same user identification information, host computer identification information, and print data file names can be canceled without complicated operations.

  The cancellation condition may be a condition regarding at least one of the size of the recording medium, the type of the recording medium, the recording medium discharge destination, and post-processing after image formation by the image forming unit. Accordingly, a cancel condition according to the state of the image forming apparatus can be set and an unexecutable print job can be automatically canceled, so that it is possible to save time and effort of the user or administrator.

  The condition setting means can set a cancellation condition and a valid period during which the cancellation condition is valid. By setting the effective period of the cancellation condition, it is possible to eliminate the need to cancel the cancellation condition setting.

  The image forming apparatus notifies the user that the print job has been canceled when the input print job matches the cancellation condition and the cancellation unit cancels the print job from the job recording unit. Notification means can be further included. Accordingly, since the user can be notified that the print job has been canceled, convenience can be improved.

  An image forming system according to the present invention is connected to the image forming apparatus and the image forming apparatus via a network, generates print data, and performs a print job for performing image formation based on the print data. And a client device that transmits to the network.

  According to the image forming system of the present invention, the client device generates print data and transmits a print job for performing image formation based on the print data to the image forming device.

  In the image forming apparatus, when the print job transmitted from the client apparatus matches the cancellation condition set by the condition setting unit, the transmitted print job is canceled from the job storage unit by the cancellation unit.

  The image forming apparatus of the image forming system further includes a transmission unit that transmits condition data indicating a cancellation condition set by the condition setting unit to the client device. The client device receives the condition data received from the image forming device. Based on the above, the cancellation condition indicated by the condition data can be displayed. As a result, since the condition data of the set cancellation condition is transmitted to the client device, it is possible to know whether or not the user can execute the print job before sending a print job execution request. Can be prevented.

  The image forming apparatus of the image forming system further includes a transmission unit that transmits condition data indicating a cancellation condition set by the condition setting unit to the client device. The client device receives the condition data received from the image forming device. Based on the above, it is possible to prohibit transmission of a print job that matches the cancellation condition indicated by the condition data. As a result, it is possible to automatically avoid the transmission of an unexecutable print job by determining whether or not the print job to be transmitted matches the cancellation condition set in the image forming apparatus. Sending a print job can be prevented.

  As described above, according to the image forming apparatus and the image forming system of the present invention, the cancel condition for the print job to be canceled is set, and the print job that matches the cancel condition is cancelled. Therefore, a plurality of print jobs are cancelled. Even in this case, it is possible to cancel the print job without performing a complicated operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the embodiment of the present invention, a case where the present invention is applied to an image forming system including a client PC, a host computer, and an image forming apparatus will be described as an example.

  As shown in FIG. 1, the image forming system 10 includes an image forming apparatus 12 that performs image forming processing, a plurality of client PCs 14 for generating and editing print data, and a host computer 15 that manages the client PC 14. The image forming apparatus 12, the client PC 14, and the host computer 15 are connected to each other via a network 16 such as a LAN (Local Area Network).

  The image forming apparatus 12 controls the entire image forming apparatus 12 and also controls a print data input control, a print job scheduling control, and an HDD 24 data management control described later, and a set cancel condition. A cancel condition storage unit 20 that stores a print job, a job registration unit 22 that reserves and registers job information indicating a requested print job that has not been executed, and an original image is read by a scanner or the like and printed An image reading unit 24 for inputting data, an image reading unit 24, and an HDD 26 for storing print job data including print data input from the client PC 14 and the host computer 15 are provided.

  The system control unit 18 includes a CPU, a ROM, and a RAM, and a program for executing a condition setting cancel processing routine and a job request cancel processing routine described later is stored in the ROM.

  Further, the image forming apparatus 12 executes a print job, performs an image forming process based on the print data of the print job data stored in the HDD 26, and forms an image on a recording sheet. A list of reserved and registered job information, a cancel condition, other settings such as settings of the image forming apparatus 12 and an operation panel unit 30 for performing setting input operations, and a network 16 connected to the client PC 14 and the host computer 15 And a communication interface 32 for transmitting and receiving data.

  Each of the cancel condition storage unit 20, job registration unit 22, image reading unit 24, HDD 26, image forming unit 28, operation panel unit 30, and communication interface 32 described above is connected to the system control unit 18.

  Note that the image forming apparatus 12 only needs to have the general configuration and functions of a conventionally known image forming apparatus, and the description of the general configuration and functions is omitted.

  The client PC 14 has a configuration of a general personal computer such as a CPU, ROM, RAM, HDD, keyboard, mouse, display, and the like. A printer job condition is set in the HDD and the image is printed on the image forming apparatus 12. A printer driver for transmitting a job may be installed, and the description of the configuration of the client PC 14 is omitted.

  Next, the operation according to the embodiment of the present invention will be described. First, the user operates the keyboard and mouse of the client PC 14 to generate or edit print data, and issues a print job execution instruction for forming an image based on the print data. Transmit to device 12. When the print job data is received, the image forming apparatus 12 stores the print job data in the HDD 26 and reserves and registers job information indicating the print job in the job registration unit 22.

  Then, the image forming unit 28 executes print jobs in the order of reservation registration in the job registration unit 22, performs image forming processing based on the print data of the print job data stored in the HDD 26, and prints on the recording paper. When the image is formed and the image forming process for the print job is completed, the job information reserved and registered in the job registration unit 22 is deleted, and the print job data stored in the HDD 26 is deleted.

  When the user operates the operation panel unit 30 to make a print job cancel condition setting request, a job cancel condition setting main screen is displayed on the operation panel unit 30 as shown in FIG. In the job cancel condition setting main screen, two conditions can be set with AND for one cancel condition. When condition 1 is selected, the selection button of the right detailed setting item becomes valid. The cancel condition setting items include “user ID” for specifying the condition by the user ID of the client PC 14, “host name” for specifying the condition by the name of the host computer 15, and the condition by the file name of the print data. "File name" to specify, "Paper" to specify conditions by the size or type of recording paper, "Paper feed tray" to specify conditions by paper feed tray from which storage paper is taken out, image formation Specified in “Destination” for specifying the conditions at the output destination where the printed recording paper is output, “Post-processing” for specifying the conditions in the processing after the image forming process is finished, and other conditions The user selects one of the setting items.

  When setting the effective period of the cancel condition, the effective period is set after the check box for the effective period setting is checked and the input area for the start time and end time is settable.

  Here, when “user ID” is selected as an item for detailed setting and the setting button is pressed, a user ID setting screen shown in FIG. 3 is displayed as a detailed setting screen. In the user ID input area, a user ID is input from a keyboard connected to the image forming apparatus 12 or a software keyboard displayed on the operation panel unit 30.

  Further, when “paper” is selected as an item for detailed setting and the setting button is pressed, a paper setting screen shown in FIG. 4 is displayed as a detailed setting screen. In the paper settings screen, you can specify either paper size or paper type. Checking the paper size or paper type check box enables the corresponding list, and selects the paper size or paper type to be set. . The example of FIG. 4 shows a case where “OHP” is selected as the paper type.

  As described above, by setting a cancel condition, for example, when a specific function is not usable, a job that specifies an unusable function is automatically canceled, so that the job is suspended ( This eliminates wasted time due to user and administrator operations waiting) and eliminates the need for operations such as job cancellation by the user and administrator.

  For example, when an OHP sheet is not installed in the paper feed tray of the image forming apparatus 12 or is out of paper, if an OHP sheet designation print job is executed, the printer waits for the OHP sheet to be fed, and the print job Is stopped. If OHP sheets are in stock, the print job can be continued by replenishing the OHP sheets to the specified paper feed tray. However, if the OHP sheets are out of stock and cannot be replenished, the user or administrator If the print job is not cancelled, not only the corresponding print job but also the subsequent print job is awaiting execution. In such a case, by setting that an OHP sheet is designated as a job cancellation condition, the print job designated by the OHP sheet is automatically canceled, so the user or administrator needs to cancel the print job. And there is no wasted time waiting for execution of a print job. When the OHP sheet designation cancel condition is deleted from the set cancellation conditions when the OHP sheet is available, an OHP sheet designation print job can be executed to form an image on the OHP sheet. .

  Similarly, when staples are out of stock, when some functions are out of order (such as frequent paper jams in some paper feed trays) and waiting for repair, etc. By setting “tray N designation” or the like as a cancellation condition, it is possible to save the user and the administrator.

  Further, as described above, in the state where the cancel condition is set, when the operation panel unit 30 is operated to instruct to display a list of the set cancel conditions, the operation panel unit 30 is as shown in FIG. The cancel condition display screen is displayed.

  In FIG. 5, four cancel conditions are set, and two conditions can be set by AND for one cancel condition. No. The cancel condition 1 is based on the user ID, and all print jobs from the user with ID 12345 are canceled. It should be noted that this is a print job input between the start time (for example, 2006/3/12 12:00) and the end time (for example, 2006/3/19 12:00) which is the effective period of this condition. Only print jobs that meet the cancellation conditions are canceled.

  No. As the cancellation condition of No. 2, the file name is “Report *” (* represents any plural characters), the host name is set to “JIMU-PC”, and is sent from the host computer 15 of the host name “JIMU-PC”. All print jobs for forming an image based on the print data having the file name “Report *” are cancelled. It should be noted that this is a print job input from the start time (for example, 2006/3/10 15:30) to the end time (for example, 2006/3/10 17:00) which is the effective period of this condition. Only print jobs that meet the cancellation conditions are canceled.

  No. 3 is designated as the paper feed tray 1, and all print jobs for taking out the recording paper from the tray 1 are cancelled. Since no valid period is set, the cancel condition setting is valid until this condition is deleted, and all print jobs that meet this condition are canceled until the condition is deleted. .

  No. As the cancellation condition No. 4, an OHP sheet that is a type of recording paper is specified, and all jobs for which an OHP sheet is specified as a recording paper to be printed are canceled. Since the expiration date is not set, it remains valid until this condition is deleted.

  Further, a delete button is displayed on the right side of the cancel condition on the cancel condition display screen. When canceling the cancel condition, the condition can be canceled by pressing the delete button. Although not shown in the figure, in addition to the delete button, an edit button can be displayed to change the cancel condition.

  As described above, when the cancel condition is set, the system control unit 18 executes a condition setting cancel process routine for performing job cancellation shown in FIG.

  First, in step 100, it is determined whether or not there is a print job reserved and registered in the job registration unit 22. If the print job is not registered for reservation, the condition setting cancel processing routine is terminated. On the other hand, if the print job is registered for reservation, in step 102, the first print job registered for reservation is set as a print job to be determined. If the print job being executed is in a cancelable state, the print job being executed is set as a print job to be determined before the first print job registered for reservation.

  In the next step 104, it is determined whether or not the print job to be determined matches the set cancel condition. If the cancel job does not match the cancel condition, the process proceeds to step 110. In step 106, job cancel processing is executed to cancel the determination target print job registered in the job registration unit 22 and cancel the determination target print job data stored in the HDD.

  In step 108, a message indicating that the determination target print job has been canceled is displayed on the operation panel unit 30, and the print job is canceled to the client PC 14 that has transmitted the determination target print job. A message is transmitted to notify the client PC 14. At this time, the client PC 14 displays on the display (not shown) that the print job has been canceled based on the message transmitted from the image forming apparatus 12, and notifies the user that the print job has been canceled. .

  In step 110, it is determined whether or not the next print job of the determination target print job is reserved and registered in the job registration unit 22. If there is a next print job, the next print job is determined in step 112. The job is set as a print job to be determined, and the process returns to step 104 to determine whether or not the cancel condition is met. On the other hand, when the processes in steps 104 to 108 are performed for all print jobs registered for reservation, the condition setting cancel process routine is terminated.

  As described above, when the condition setting cancel processing routine is executed, all print jobs waiting to be executed that match the set cancellation condition are canceled, and the job information of the print job is canceled from the job registration unit 22. The print job data of the print job is canceled from the HDD 26.

  Next, a case where a new print job is input and execution of the print job is requested will be described. A user sets an original on the image reading unit 24 and operates the operation panel unit 30 to input an execution instruction for a print job for forming an image based on print data of the original image, or the client PC 14 or the host computer 15. When the print job data is transmitted from, the system control unit 18 executes a job request cancel process routine for canceling the job shown in FIG.

  First, in step 120, it is determined whether or not the reception of print job data has been completed. When the print job data has been received from the client PC 14 or the host computer 15 and the print job data has been stored in the HDD 26, an operation panel is displayed. If the print job is input and the print job data is stored in the HDD 26 when the unit 30 is directly operated, the process proceeds to step 122 to determine whether or not the cancel condition is stored in the cancel condition storage unit 20. To do. If the cancel condition is not set and the cancel condition is not stored in the cancel condition storage unit 20, the process proceeds to step 140. However, the cancel condition is set and the cancel condition is stored in the cancel condition storage unit 20. If stored, the number n for identifying the cancel condition is set to an initial value of 1 in step 124.

  In the next step 126, it is determined whether or not the cancellation condition n is valid. If the expiration date is set in the cancellation condition n. If the expiration date has passed, the cancellation condition n is set in step 128. It deletes from the cancellation condition memory | storage part 20, and transfers to step 136. FIG. On the other hand, if it is within the expiration date of the cancel condition n or no expiration date is set, it is determined in step 130 whether or not the input print job matches the cancellation condition n. If the cancel condition is not met, the process proceeds to step 136. On the other hand, if the cancel condition is met, job cancel processing is executed in step 132, and the print job data of the input print job is transferred from the HDD 26. cancel.

  In step 134, a message indicating that the input print job has been canceled is displayed on the operation panel unit 30, and the print job is canceled to the client PC 14 that has transmitted the input print job. A message indicating that the print job has been canceled is displayed on the display (not shown) of the client PC 14, and the job request cancel processing routine is terminated.

  In step 136, it is determined whether or not the cancel condition n + 1 is stored in the cancel condition storage unit 20. If the cancel condition n + 1 is not set, the process proceeds to step 140, but there is a cancel condition n + 1. In step 138, the value of n is incremented, and the above steps 126 to 134 are executed for the next cancellation condition.

  In step 140, the input print job is reserved and registered at the end of the job registration unit 22, and the job request cancel process routine is terminated.

  As described above, when the job request cancel processing routine is executed, the input print job is canceled if the input print job meets any of the already set cancellation conditions. The reservation is not registered.

  As described above, according to the image forming system according to the first embodiment, the cancel condition regarding the print job to be canceled is set and the print job that matches the cancel condition is canceled. Even when canceling, the print job can be canceled without a complicated operation.

  In addition, since a print job that matches a preset cancellation condition can be canceled, the print job can be canceled without performing another cancel operation on the newly input print job.

  In addition, when a print job that takes a long time to complete the reception and registration of a print job, such as a large document or a large number of documents, is mistakenly sent from a client PC, the user of the user who sent it By setting the ID, host name, file name of the print data of the transmitted print job, etc. as cancellation conditions, the print job can be set to be automatically canceled without waiting for completion of reception of the print job data. it can. In addition, when a large number of print jobs are erroneously transmitted, it is not necessary to individually designate and cancel individual print jobs, and all print jobs can be canceled simply by setting cancellation conditions.

  Also, a plurality of print jobs having the same user ID, host name of the host computer, and print data file name can be canceled without complicated operations.

  In addition, since it is possible to automatically cancel a non-executable print job by setting a cancel condition according to the state of the image forming apparatus, it is possible to save time and effort for the user or the administrator.

  Also, by setting the effective period of the cancel condition, it is possible to eliminate the need for canceling the cancel condition setting.

  When the print job is canceled, the user can be notified that the print job has been canceled, so that convenience can be improved.

  In the above-described embodiment, the case where the cancel condition for which the valid period has passed is canceled in the condition setting cancel processing routine has been described as an example. However, the present invention is not limited to this, and the valid period has elapsed. Sometimes, the cancellation condition whose valid period has passed may be automatically deleted by the system control unit 18.

  In the job request cancel processing routine, after the reception is completed, the cancel condition is determined and the print job is cancelled. However, the print job setting can be performed without receiving all the print job data. When the information regarding the condition is received, the cancel condition may be determined to cancel the print job. In this case, when canceling a print job, reception of print job data may be stopped to prevent reception of unnecessary print job data. Thereby, even when the print data capacity of the print job is large, the print job can be automatically canceled without waiting for the completion of reception of the print job data.

  Also, as a method for canceling a print job, only the method for setting a cancel condition has been described. However, as in the past, a function for canceling a print job individually by inputting a print job identifier is provided, and a normal cancel operation is performed. It may be possible to perform.

  Next, an image forming system according to a second embodiment will be described. In addition, about the part which has the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the second embodiment, the cancel condition set on the client PC side can be confirmed, and whether or not the cancel condition set on the client PC side is met is canceled. The main difference from the first embodiment is that transmission of a print job that matches the conditions is prohibited.

  The image forming apparatus 12 according to the second embodiment transmits condition data indicating the set cancellation condition to the client PC 14. Then, the client PC 14 stores the condition data transmitted from the image forming apparatus 12 in the memory, and based on the condition data, the printer status display tool on the display of the client PC 14 is similar to the example shown in FIG. A list of currently set cancellation conditions and an expiration date are displayed.

  The user can change the condition of the print job or select an image forming apparatus that transmits the print job by looking at the displayed cancellation condition list.

  Further, the printer driver or application software of the client PC 14 determines whether or not a print job instructed by the user can be executed, and prohibits transmission of a print job that matches the cancel condition.

  Next, the operation of the second embodiment will be described. Note that the operation of the image forming apparatus 12 is the same as that of the first embodiment, and a description thereof will be omitted.

  In the client PC 14, a printer job condition is set, and when the printer job is transmitted, the cancel condition determination processing routine shown in FIG. 8 is executed in the printer driver.

  First, in step 200, it is determined whether or not a print job execution instruction has been input. When the user sets a print job condition on the client PC 14 and presses the execution instruction button, the process proceeds to step 202, where the image forming apparatus is set. Whether or not the condition data of the cancel condition is received from 12 is determined. In the image forming apparatus 12, when the cancel condition is not set and the condition data is not transmitted from the image forming apparatus 12, the process proceeds to step 218, but the cancel condition is set and the image forming apparatus 12. If the condition data has been transmitted from, the number n for identifying the cancel condition is set to an initial value of 1 in step 204.

  In the next step 206, it is determined whether or not the cancellation condition n is valid. If the expiration date is set in the cancellation condition n and the expiration date has passed, the process proceeds to step 214. If it is within the expiration date of the cancel condition n or no expiration date is set, it is determined in step 208 whether or not the print job instructed to execute meets the cancellation condition n. If the cancel condition is not met, the process proceeds to step 214. On the other hand, if the cancel condition is met, a warning message is displayed together with the cancel condition n in step 210, and the user cannot execute the print job. To be notified. In step 212, it is determined whether or not the print job condition has been changed by the user. If the print job condition has not been changed, the cancel condition determination processing routine is terminated. When the print job condition is changed by the user on the print job setting screen, the process returns to step 204 to determine whether or not the print job whose condition has been changed satisfies the cancel condition.

  In step 214, it is determined whether or not the cancel condition indicated by the transmitted condition data includes the cancel condition n + 1. If the cancel condition n + 1 is not set, the process proceeds to step 218. If there is, in step 216, the value of n is incremented and the above steps 206 to 212 are executed for the next cancel condition.

  In step 218, the print job data of the print job for which execution has been instructed is transmitted to the image forming apparatus 12, and the cancel condition determination processing routine ends.

  As described above, when the cancel condition determination processing routine is executed, it is determined whether or not the print job instructed to execute satisfies the cancel condition, and if the cancel job satisfies the cancel condition and cannot be executed, The user is notified that it is not executable. In addition, the user can change the print job condition setting so that it does not match the cancel condition, and issue a print job execution instruction.

  As described above, according to the image forming system according to the second embodiment, since the image forming apparatus transmits the condition data of the set cancellation condition to the client PC, the user requests to execute the print job. It is possible to know whether or not the job can be executed before submitting the print job, and it is possible to prevent sending a useless print job.

  In addition, by determining whether the print job to be transmitted matches the cancellation condition set in the image forming apparatus on the client PC, transmission of an unexecutable print job can be automatically avoided, and wasteful printing can be performed. It is possible to prevent the job from being transmitted.

  In the above example, the cancel condition and warning message are displayed when the print job instructed to execute matches the cancel condition. However, if the print job condition can be changed, it can be executed. Alternatively, the condition contents of the alternative print job may be displayed to allow the user to select.

  In addition, if the set cancellation condition is a condition related to the function of the image forming apparatus, the function specified in the cancellation condition cannot be selected on the print job condition setting screen of the printer driver or application. By not activating the check box or button to be activated, transmission of a print job that matches the cancellation condition may be prohibited.
