Description

  The present invention relates to a software that generates a job that can be printed by a printing apparatus on a host computer and a print control apparatus that prints the job, a printing system that changes print job data generated by an intermediate language file, an information processing apparatus, The present invention relates to a printing apparatus, a print job generation method, a program, and a recording medium.

  In recent years, the processing capacity of the host computer, the storage area of the storage device / memory, the processing speed, the network speed, and the like have been greatly improved, and the processing capacity of the printing apparatus has also been improved. The environment that constitutes today's printing system has greatly improved in terms of processing power.

  To perform a generally large amounts of data printed in the trunk system printing, fast printing apparatus having a printing speed is utilized. In such a basic printing system, there are many cases in which a large amount of form data is printed, but the number of print pages per job is a large number of pages or a small number of pages, and the form differs depending on the printing field.

  However, when continuously printing a small amount of pages / jobs, the initialization process between jobs in the print control apparatus occupies a large weight with respect to the page data drawing process.

  The initialization processing between jobs includes “Job start processing”, “Job end processing”, and “Print completion processing”, and “Job start processing” and “Job end processing” are jobs for analyzing and developing print jobs, respectively. There is a process that starts and ends the analysis development processing task.

  If a plurality of page description languages (PDL: Page Description Language) are described in the job, these processes occur multiple times, and the job analysis development processing task itself is also executed multiple times.

  A print job is composed of “job control information” that is command information for controlling the entire job, and “job drawing information” that is command information for drawing page data of the job. The former is “PJL” and the latter is “job drawing information”. “PCL”, “PostScript (R)”, and the like are used as typical commands. “Job control information” includes printing resolution, full-page printing on paper, and stapling of post-processing functions. However, when form data is continuously printed in small pages / jobs, job control information is used in most cases. Can be said to have the same content.

  Generally, as described above, there are many cases where a print job is generated by a plurality of PDLs, and job initialization processing and job analysis and expansion processing are executed for a plurality of PDLs. Since the weight other than analysis development processing for drawing becomes very large, there is a case where the printing speed is lowered and intermittent printing is performed, which is a big problem in basic printing. For example, there is a case that the printing apparatus of 70ppm is reduced speed until the 20ppm in continuous printing of 1 page / job.

  For example, Patent Document 1 discloses a printing system environment that can efficiently perform printing while maintaining the maximum throughput without impairing the output capability of the printing apparatus, even if the printing process is delayed depending on the type of data. A printing system that can be freely configured is disclosed.

  Also, for example, Patent Document 2 discloses an invention in which print data processing, which takes time because single page processing is performed, is continuously printed in a two-page formation mode to improve throughput. Further, in Patent Document 3, when a combination instruction for making a plurality of print jobs into one combination job is made, the print setting information of the plurality of print jobs is analyzed, and only one is set for one print job. It is described that print setting information for a combined job that unifies information that cannot be generated is generated.

  In the method described in Patent Document 1, data conversion processing is performed depending on the type of drawing data. However, this processing emphasizes a large number of pages / jobs, and consideration is given to continuous printing of a small amount of pages. There was a problem that was not.

  A bottleneck in continuous printing of a small amount of pages is print processing other than page data rendering processing, that is, job initialization processing generated for each job, but print jobs generated in a plurality of page description languages In this case, there is a problem that it takes time to initialize the job.

  In addition, the methods described in Patent Document 2 and Patent Document 3 generate a job including job control information for each page for the purpose of combining jobs, and as a result, job control information The job analysis and expansion process for hinders the improvement of throughput.

  Accordingly, the present invention has been made in view of the above problems. When the number of print pages of the job is small, job control information is not output, and only job drawing information is generated, thereby generating a small number of pages continuously.

  Here, the structure of a conventional printing system will be described.

  FIG. 6 shows a printing flow of the conventional printing system.

  Here, the description will be made on the assumption that the operating system 200 of FIG. 6 is Microsoft Windows (registered trademark) and the printer driver 230 is an intermediate language spooling format (EMF format).

  The host computer 100 includes an operating system 200 that is basic software for operating the computer, application software 210 for creating and printing a document thereon, a drawing engine (Graphics Device Interface: (GDI)) 220, and a printer driver. 230 and a print spooler 240.

  In response to a print instruction from the application software 210, a drawing command (Graphics Device Interface: (GDI)) that instructs the printing apparatus is temporarily stored as an intermediate language file in the EMF format via the GDI 220 of the drawing engine (Graphics Device Interface: (GDI)).

  Then, the print processor 241 of the print spooler 240 instructs the GDI 220 to print each page data in order based on the intermediate language file, and a rendering function called a device driver interface (DDI) from the GDI 220 to the printer driver 230. A call is made.

  The first DDI call from the GDI 220 is for acquiring the drawing ability of the printer driver, and thereafter is the DDI for text / image / graphic drawing on each page data.

  First, the printer driver 230 generates job control information in accordance with a driver setting option set in the user interface 231. Next, the DDI call from the drawing engine GDI 220 is converted into page description language (PDL) data that can be decoded by the printing apparatus, and transmitted to the printing apparatus 400 via the port monitor 242 and the bidirectional interface 300. Is done.

  Received in the printer 400 to print job by the data reception processing section 411, and command analysis jobs in job analysis development processing unit 412 to expand the image data. The transmitted to the engine mechanism not shown printer image data developed by the engine control unit 413 as video data, is printed on the recording paper.

  The user interface 231 serves as an interface with the operator in the printer driver 230, and print options that can be specified by the printing apparatus can be set and held.

  The print processor 241 is activated by a print request for an intermediate language file from the print spooler 240. FIG. 7 shows a flowchart of processing in the print processor. First, the print processor 241 obtains an intermediate language file (step 100: S100 (hereinafter, the same applies)), instructs the GDI 220 of the rendering engine to sequentially print each page data of the intermediate language file (S101), and the page. The process continues until the output of data is completed (S102). This is continued until all pages have been output (S103), and after the output is completed, this processing ends.

  FIG. 8 shows a flowchart of processing in the print job generation processing unit. The print job generation processing unit 232 generates and outputs a job control command based on the current setting of the user interface 231 (S200), converts it into PDL data according to a print request from the GDI 220 by “drawing data print processing” (S201), The process continues until the output of the page is completed (S202). This is continued until all pages are output (S203), and after the output is completed, this processing ends.

  Details of S201: “drawing data printing process” in FIG. 8 will be described. FIG. 9 shows a flowchart of the drawing data printing process. In the “drawing data printing process”, if a text data printing request is made (S300), a text data drawing command is generated and output (S301). If an image data printing request is made (S302), an image data drawing command is issued. Is generated and output (S303). Otherwise, a graphic data drawing command is generated and output as graphic data (S304).

  The print flow and process flow of the conventional printing system have been described above.

Example 1
Next, a first embodiment according to the present invention will be described.

  FIG. 1 is an overall block diagram of a printing system showing an example of a print job generation method according to the first embodiment.

  In this embodiment, a print page number information extraction processing unit 243 that extracts print page number information from an intermediate language file is added to the print processor 241 with respect to the conventional example of the printing system shown in FIG. 230, a job control information designation processing unit 233 for determining whether or not to generate job control information on the condition of the number of print pages extracted by the print processor 241 is added to the print job generation processing unit 232. The analysis development processing unit 412 is configured to add the job control information reading processing unit 414 that reads the immediately preceding job control information by specifying the job control information reading mode from the printer driver 230 and reflects it in the job control information of the job.

  Processing of the print processor 241 in this embodiment will be described. FIG. 2 shows a flowchart of processing in the print processor 241. It should be noted that portions added to the conventional flow in FIG. 7 will be described in detail, and detailed description of portions similar to the conventional flow will be omitted. In this process, after obtaining an intermediate language file requested to be printed from the print spooler 240 (S100), a process (S110) for analyzing the intermediate language file and extracting print page number information is added.

  Next, processing of the print job generation processing unit 232 will be described. FIG. 3 shows a flowchart of the print job generation process. Note that and only will be described in detail moiety added to the conventional flow of FIG. 8, for the conventional flow and similar parts will not be described in detail. In this process, prior to the process of “Generate and output job control information based on user interface settings” (S200) in the conventional flow of FIG. 8, “print page number information” extracted in S110 of FIG. 2 is designated in advance. In order to read the previous job control information (S211), the previous print job and the job control information of the job are compared (S211). A process of specifying a job control information reading mode (S212) is added to the print control apparatus. A specific example of this process will be described below.

  FIG. 4 shows an example of the print data and print page number analysis result in the first embodiment of the present invention. For example, as shown in FIG. 4, a case is considered in which job control information is generated by PJL, job drawing information is generated by PCL, and 100 jobs are continuously printed.

Note that the "job control information" above refers information for controlling the entire job. For example, it corresponds to a resolution = 600 dpi, the control information over the entire surface printing = ON, and the specified. Then, what is expressed as a job (recognized by the printer) is recognized as a job control language (PJL: Printer Job Language).
Further, the above-mentioned “job control information is generated by PJL” means that “job control information” is generated as a print job in the job control language “PJL”.

  Note that software that creates and processes intermediate language files exists on the operating system, the printer driver is capable of intermediate language file spooling, and intermediate language file spooling is enabled on the user interface. (Hereafter, similarly, this condition is assumed to be the same).

  From the form software, the job No. When 1 is printed, it is temporarily created as an intermediate language file by the GDI 220 which is a drawing engine.

  After the intermediate language file is created, the print spooler 240 issues a print request to the print processor 241. The print processor 241 analyzes this file and extracts the number of print pages of the job (see FIG. 4).

  After the extraction, the printer driver 230 compares the job control information with the previous job because it is within the specified value by “print page number specification 1 page ≧ extraction number 1 page”. of course, since the difference in the job control information is there, to generate the job control information based on the user interface 231 in the PJL command.

  Then, the drawing command information, and transmits the job drawing information and job generation into a PCL command sequence to the print control apparatus 410. The print control apparatus 410 stores the job control information of the job, the PJL command / PCL command sequence to command analysis development and printing.

  Subsequently, the job No. 2 is a value other than the specified value due to “print page number specification 1 page <extraction 2 page”, so that the printer driver 230 generates job control information as a PJL command sequence, and generates job drawing information as a PCL command sequence. To the print control apparatus 410.

  The print control apparatus 410 stores the job control information of the job, the PJL command / PCL command sequence to command analysis development and printing.

  Next, the job No. 3 is within the specified value by “print page number specification 1 page ≧ extraction number 1 page”, and when it is confirmed that there is no difference between the immediately preceding job control information and the job, only the job drawing information is a PCL command. It is generated as a sequence and transmitted to the print control device together with the job control information reading mode designation.

  Here, how to determine the above “no difference” will be described. This processing is processing in the printer driver 230. This determination is made by comparing the job option values (resolution, full-face print designation, etc.) on the driver settings between immediately before and at present. Therefore, it is determined not by size but by each value of the job option.

  The print control apparatus 410 determines whether the received job is in the “job control information reading mode” designated by the job control information designation processing unit 233, and if it is the job control information reading mode, the job control information reading processing unit. At 414, the stored job control information of the immediately preceding job is read, reflected as the job control information of the job, and the PCL command string is command-analyzed and printed.

  Thereafter, since the number of printed pages and the job control information are the same, no. Prints up to 100.

  As described above, since only the minimum necessary job control information is output based on the number of print pages specified in advance according to the capabilities of the print control device, the print control device also has job drawing information that becomes a single page description language. No. print processing only. 3 and later, continuous print processing can be performed without performing job initialization processing and PJL command analysis development processing for job analysis development processing, so that the efficiency of print processing for this case can be increased.

  Further, according to the above embodiment, when the number of pages of a job is small, when using the previous job control information, it is determined whether the job control information may be different, and the control information of each job is the same In this case, the immediately preceding information is taken over in the printing control apparatus and printing processing is performed.

(Example 2)
Next, a second embodiment according to the present invention will be described.

  The second embodiment differs from the first embodiment only in the conditions for determining whether or not job control information is generated, and the basic processing is the same as the flowcharts of FIGS. Therefore, detailed description of the same parts as in the first embodiment will be omitted.

  FIG. 5 shows print data and drawing command number analysis results in the second embodiment of the present invention. For example, as shown in FIG. 5, consider a case where a print job is generated with job control information: PJL and job drawing information: PCL, and 100 jobs are continuously printed from form software.

  From the form software, the job No. When 1 is printed, the drawing engine GDI 220 temporarily creates an intermediate language file.

  After the intermediate language file is created, the print spooler 240 issues a print request to the print processor 241. The print processor 241 analyzes this file, extracts the number of job drawing commands, and totals text / graphics / images (see FIG. 5). ). After the extraction, the printer driver 230 compares the job control information with the immediately preceding job control information because the number is within the specified value by “drawing command number designation 100 ≧ extraction number 100”. Since there is a difference in job control information, job control information based on the user interface is generated by a PJL command.

  Next, based on the drawing command information, the job drawing information is converted into a PCL command sequence, a job is generated, and is transmitted to the print control apparatus 410.

  Subsequently, the job No. 2 is a value other than the designated value because “drawing command number designation 100 <extraction number 150”, the printer driver 230 does not create job control information, and only the job drawing information is generated as a PCL command string and the print control apparatus 410. Send to. The print control apparatus 410 stores the job control information of the job, the PJL command / PCL command sequence to command analysis development and printing.

  Next, the job No. 3 is within the specified value because “drawing command number designation 100> extraction number 60”, and it can be confirmed that there is no difference between the previous job control information and the job, only the job drawing information is a PCL command string. And is transmitted to the print control apparatus together with the job control information reading mode designation.

  The print control apparatus 410 uses the job control information reading processing unit 414 to request reading the job control information of the immediately preceding job stored in the “job control information reading mode” specified by the job control information specifying processing unit 233. The job control information of the immediately preceding job is read, reflected as the job control information of the job, and the PCL command string is command-analyzed and printed.

  Thereafter, since the number of printed pages and the job control information are the same, no. Prints up to 100.

  As described above, as in the first embodiment, only the minimum necessary job control information is output according to the number of drawing commands specified in advance according to the capability of the print control apparatus, and the print control apparatus also has a single page description language. Only the print processing of the job drawing information that becomes No. From 3 onward, continuous print processing can be performed without performing job initialization processing and PJL command analysis development processing for job analysis development processing, so that the print processing efficiency for this case can be increased.

  Further, according to the above embodiment, when the previous job control information is used when the number of pages of the job is small, there may be different job control information. This information can be taken over in the print control apparatus and can be printed.

  In the first and second embodiments described above, the determination conditions for whether or not job control information is generated are determined by the number of print pages and the number of drawing commands, respectively. These determination conditions can be changed. Thus, it is possible to define it in accordance with the processing capability of the printing apparatus.

  Also, depending on the print job, the job name may be generated as job control information. In this case, it is possible to prevent the job control information from always being output by separately transmitting it to the printing apparatus side.

  According to the above embodiment, the print processor extracts the number of print pages for the job, and the printer driver does not output the job control information according to the number of print pages, and the job control of the job stored in the print control apparatus is stored. By using the information, the print processing of only the job drawing information is performed, so that it is possible to improve the print processing efficiency in continuous printing of a small amount of pages.

  Further, according to the above-described embodiment, it is possible to set the determination condition for the presence / absence of job control information generation not only by the number of print pages but also by the number of drawing commands, so that it is possible to improve the print processing efficiency similarly. Become.

  Further, according to the above-described embodiment, the number of print pages and the number of drawing commands are not fixed values but can be changed, so that it is possible to generate a print job according to the capability of the printing apparatus.

  In the printing system according to the present invention, the print processor includes a drawing command extraction unit that analyzes an intermediate language file and extracts drawing command information, and the printer driver uses the drawing command information of the job to execute the drawing command information. The job control information is not generated, and only the job drawing information is generated.

  The printing system according to the present invention is characterized in that the print page number information and the drawing command information in the printer driver can be changed instead of fixed values.

  In the print job generation method according to the present invention, the print processor includes a drawing command extraction step of analyzing an intermediate language file and extracting drawing command information, and the printer driver uses the drawing command information of the job. the no job control information job generation, characterized by having a step of only job generation the job drawing information.
