BACKGROUND OF THE INVENTION
The present invention relates to a printing system that performs printing processing on continuous paper by a printing apparatus capable of printing on continuous paper. More specifically, the present invention relates to a printing system capable of reprinting a page that could not be discharged after the jam recovery when the page printed on the continuous paper could not be discharged due to the jam.
[0002]
[Prior art]
In printing processing on continuous paper by a printing device capable of printing on continuous paper, image data for displaying individual pages of printed matter is printed when printing processing on continuous paper by the transfer and fixing process is completed. Deleted from the memory. The memory is used to store the next data to be transferred, and the page printed on the continuous paper is transported along the paper transport path and discharged from the paper discharge port. However, there is a possibility that a paper jam (jam) may occur in the transport path from the point where printing on the continuous paper ends to the discharge port. In such a case, the page that could not be discharged due to the jam is reprinted. Attempts to do so cannot be made because the original image data has already been discarded and is not in memory.
[0003]
On the other hand, a printing system has been proposed in which the printer intermediate language data stored in the server in parallel with the printing process of the printer is read from the undischarged page and reprinted when a jam occurs (see Patent Document 1). ). However, in such a print system, when a print job is sequentially received and processed, when a page that could not be ejected due to a jam is reprinted from the middle of the print job, a method for correctly reflecting setting information such as a job header. The problem was not solved.

[0024]
Next, an outline of the operation of the printing system in the present embodiment will be described. FIG. 4 is a flowchart showing the procedure of the print control process of the print control apparatus 1 in the present embodiment. The algorithm shown in the flowchart of FIG. 4 is stored as a control program in the ROM 12 or the hard disk 14 of the print control apparatus 1, read out to the RAM 13 at the start of operation, and executed by the CPU 11.
[0025]
In FIG. 4, the print control apparatus 1 first performs sequential reception processing of print jobs (S101). That is, the PC 3 creates a print job in a predetermined format and sequentially transmits it to the print control apparatus 1. The print control apparatus 1 sequentially receives the print jobs from the PC 3 via the network 4 and the network interface 17, and the hard disk 14. Is stored in a predetermined area. FIG. 5 is a diagram for explaining a data structure of received data received from the PC 3 by the print control apparatus 1 in the present embodiment. As shown in FIG. 5, the received data 5 received by the print control apparatus 1 includes a plurality of print jobs. One print job has one job header and pages corresponding to the number of pages of the printed matter related to the print job. Contains header and print data. The job header contains the number of printed pages, the number of copies, the paper size (all based on the paper after separation), the type of image processing mode such as characters, graphics, and photographs, and color information such as monochrome or color. In addition, setting information that is applied to the entire print job is included, such as information on whether or not a sheet has been separated after printing. Further, the page header includes setting information that applies only to the page, such as information on the image size (number of pixels in the vertical and horizontal directions, data length, etc.) of the image data constituting the page. Further, the print data is data for generating an image constituting each page of the printed matter related to the print job, and is created in a description language format that can be interpreted by the print control apparatus 1.
[0026]
Next, the print control apparatus 1 performs image processing of the sequentially received print jobs (S102). FIG. 6 is a flowchart illustrating a procedure of image processing of a print job performed by the print control apparatus 1 in the present embodiment. In FIG. 6, the print control apparatus 1 first extracts a job header from the first received print job and adds it to the end of the print queue (S201). Here, the print queue is a queue for sequentially transmitting a job header, page header, and image data obtained by image processing of a print job to the printing apparatus 2. In this case, data such as image data is actually stored in a predetermined area such as the hard disk 14 and is managed and processed according to a queue of a print queue separately stored in the RAM 13 or the like. In the embodiment, for convenience, the print queue is a temporary storage area for data, and the data is described as forming a permutation for transmission processing in the area.
[0027]
Next, the page header relating to the first page of the print job is extracted and added to the end of the print queue (S202), the print data relating to the page is rasterized (S203), and the obtained image data is printed. It is added at the end of the queue (S204). Similarly, for each page header and print data included in the print job, page header extraction and print data rasterization are sequentially performed, and the obtained page header and image data are added to the end of the print queue. Go (NO in S202 to S205).
[0028]
When processing for all page headers and print data included in the print job is completed (YES in SS205), image processing is sequentially performed for other received print jobs in the same procedure (NO in S201 to S206). When the image processing for all received print jobs is completed (YES in S206), the image processing process for the print job in step S102 is terminated.
[0029]
Next, the print control apparatus 1 performs transmission processing of the image data acquired by the image processing of the print job (S103). FIG. 7 is a flowchart illustrating a procedure of image data transmission processing performed by the print control apparatus 1 in the present embodiment. In FIG. 7, the print control apparatus 1 first determines whether or not a print cancel instruction has been received from the print apparatus 2 (S301). If no print stop instruction has been received (S301: NO), the print queue The first job header, page header, and image data are transmitted to the printing apparatus 2 via the printer interface 18 (S302), and the transmitted job header, page header, and image data are deleted from the print queue (S303). If the job header for the print job has already been transmitted, the processes of steps S302 and S303 are performed on the top page header and image data of the print queue.
[0030]
Next, it is determined whether or not the number of stored image data in the reprint queue has reached a specified number (S304). If the specified number has not been reached (NO in S304), the transmitted job header, The page header and image data are added to the end of the reprint queue (S306). Here, the reprint queue is a queue for retransmitting image data and the like for reprinting to the printing apparatus 2 when performing reprinting after recovery when a jam occurs in the printing apparatus 2. . That is, when a page printed on continuous paper by the printing apparatus 2 cannot be ejected due to a jam, a predetermined number of transmitted image data is preliminarily set in order to reprint the image data relating to the page that could not be ejected. The data is stored in a reprint queue together with the page header, and these data are sequentially transmitted to the printing apparatus 2 at the time of reprinting after recovery when a jam occurs.
[0031]
FIG. 8 is a diagram for explaining the configuration of the printing unit of the printing apparatus 2. In FIG. 8, when the image data is received from the print control device 1, the printing device 2 prints the image data on the continuous paper 28 fed from the paper feed port 251 through the transfer and fixing processes. Then, the printing apparatus 2 deletes the image data on the memory in order to receive the next data when the page related to the image data formed on the continuous paper 28 reaches the print end point 253. Therefore, if a jam occurs in the middle of the paper transport path from the print end point 253 to the paper discharge port 252, the original image data is already discarded even if an attempt is made to reprint a page that could not be discharged due to the jam after the jam recovery. This is not possible because it is not in memory. Accordingly, the print control apparatus 1 always stores the number of transmitted image data whose total page length is at least the length L of the sheet conveyance path from the print end point 253 of the printing apparatus 2 to the paper discharge outlet 252. Thus, it is possible to retransmit the image data to the printing apparatus 2 at the time of jam recovery and reprint all the pages that could not be discharged due to the jam.
[0032]
In this embodiment, as in the case of the print queue, for convenience, the reprint queue is a temporary storage area for data, and the data is considered to form a permutation for transmission processing in the area. I will explain.
[0033]
On the other hand, if the number of stored image data in the reprint queue has reached the specified number in step S304 (YES in S304), the top job header, page header, and image data in the reprint queue are deleted (S305). The transmitted job header, page header, and image data are added to the end of the reprint queue (S306). This makes it possible to always store a predetermined number of the latest transmitted image data in the reprint queue. However, when reprinting is performed using image data saved in the reprint queue, the top image data in the reprint queue is not necessarily the top image data of the print job. It is necessary to save the job header so that it can be reprinted even from the beginning. Therefore, in step S305, if image data related to the same print job as the image data to be deleted is stored in the reprint queue, the job header related to the job is the first data in the reprint queue. If the image data related to the same print job as the image data to be deleted does not exist in the reprint queue, that is, the image data to be deleted is the last data of the print job. If there is, the job header related to the print job is deleted at the same time.
[0034]
A specific example is as follows. 9 to 11 are diagrams schematically illustrating data permutations in the reprint queue of the print control apparatus 1 according to the present embodiment. 9 to 11, the data stored in the reprint queues 61 to 63 are obtained by performing image processing on the received data 5 of FIG. The number of image data stored in the reprint queues 61 to 63 is three. The reprint queue 61 transmits the first three pieces of image data obtained by performing image processing on the received data 5 (page 1 and page 2 of job 1 and page 1 of job 2) to the printing apparatus 2. It is just after. In the reprint queue 62, the page header and image data of page 1 of job 1 which is the top data of the reprint queue 61 are deleted, and page 2 of job 2 which is the fourth image data of received data 5 is deleted. Image data is added with the page header. In this case, since the image data of page 2 of job 1 remains in the reprint queue, the job header of job 1, which is the top data, remains without being deleted. In the reprint queue 63, the job header of job 1 and the page header and image data of page 2 of job 1, which are the top data of the reprint queue 62, are deleted, and the fifth image data of the received data 5 is used. The image data of page 2 of a certain job 2 is added together with the page header. In this case, since the image data of job 1 does not exist in the print queue, the job header of job 1 is deleted together with the image data of page 2 which is the last image data of job 1.
[0035]
FIG. 12 is a flowchart showing the procedure of the printing process of the printing apparatus 2 in the present embodiment. Note that the algorithm shown in the flowchart of FIG. 12 is stored as a control program in the ROM 22 of the printing apparatus 1 and is read out to the RAM 23 and executed by the CPU 21 when the operation starts.
[0036]
In FIG. 12, the printing apparatus 2 stands by until it receives a job header, page header, and image data from the print control apparatus 1 (NO in S401), and receives image data or the like from the print control apparatus 1 via the controller interface. (YES in S401), the received image data and the like are stored in the RAM 23 (S402). Here, the setting information included in the received job header is set to be reflected in the entire print processing of the job, and the setting information included in the received page header is reflected only in the image data relating to the page. Setting to be made. Then, the received image data is printed on continuous paper (S403). When printing is completed, the image data and the like are deleted from the RAM 23 (S404).
[0037]
Here, if a jam occurs in the middle of the paper conveyance path from the printing end point to the paper discharge port (YES in S405), a print stop command is transmitted to the print control apparatus 1 (S407) until the jam is resolved. Wait (NO in S408). When the jam is recovered (YES in S408), a print restart command is transmitted to the print control apparatus 1 (S409), and image data for reprinting the page that could not be discharged due to the jam is received from the print control apparatus 1. It waits until it does (NO of S401). Thereafter, the reprint image data and the remaining image data are printed according to the above procedure (NO in S401 to S404). When the last image data print process is completed (YES in S404), the print process is terminated.
[0038]
On the other hand, in FIG. 7, when the print control apparatus 1 receives a print stop command from the print apparatus 2 via the printer interface 18 (YES in S301), the print control apparatus 1 interrupts the print processing until a print resume command is received. Wait (NO in S307). When a print resumption command is received from the printing apparatus 2 (YES in S307), the top job header, page header, and image data in the reprint queue are transmitted to the printing apparatus 2 (S308), and the transmitted job header and page are transmitted. The header and image data are deleted from the reprint queue (S309). Thereafter, the transmission process is performed for the image data stored in the reprint queue by the same procedure (YES in S308 to S310), and when the transmission process for all the image data stored in the reprint queue is completed (S310). NO), returning to the normal transmission process, the image data transmission process is performed (NO in S301 to YES in S311). When the transmission processing for all the image data in the print queue is completed, the image data transmission processing is terminated (NO in S311), and the printing control processing according to the present embodiment is terminated.
