Description

  The present invention relates to a printing system, a printing method, and a program for printing corrected page data.

  Conventionally, after printing a text file, when only the corrected portion is printed again after correction such as an error, the user generally remembers the corrected page and prints by specifying the page number. However, for a text file with a large number of pages, such as a specification document, when a plurality of corrected pages are specified and printed, there is a problem that the operation efficiency is very poor.

  In view of the above problem, a technique for printing only page data that is different from the page data at the time of previous printing has been disclosed (see Patent Document 1). With this technology, the user can print only the pages that have been corrected with a simple operation, and can easily obtain the corrected document by replacing the corrected document page with the document page before the correction. Can do.

JP-A-5-303574

By the way, in recent years, paperless and recycling have been screamed from the viewpoint of effective use of resources, and even when text files are printed, duplex printing and N-up printing are often used. By using double-sided printing or N-up, a plurality of page data can be printed on a single sheet, and waste of the sheet can be prevented.
When some page data is corrected in the original printed using double-sided printing or N-up as described above, the page data adjacent to the corrected page data may not be corrected. . In such a case, in the technique disclosed in Patent Document 1 described above, only the corrected page data is printed, so only the print attribute of the document at the previous printing time and the corrected page data are printed. The print attributes at the time are different, and there is a problem that the modified page cannot be replaced.

  SUMMARY An advantage of some aspects of the invention is that it provides a printing system, a printing method, and a program that can easily replace a corrected document page for a document that uses double-sided printing or N-up.

  The object is to extract, from the digitized text file in which a plurality of page data adjacent to each other has been printed on one sheet, the page data whose contents have been corrected since the time of printing, and the corrected Print data for printing page data and uncorrected page data printed on the paper adjacent to the corrected page data on a single sheet in consideration of the print attributes at the time of printing. This can be achieved by a printing system including a print data creation unit for creating a print data.

With this configuration, a part of page data of a document printed based on printing attributes such as double-sided printing and N-up is corrected, and page data adjacent to the corrected page data is not corrected. In this case, the corrected page data and the uncorrected page data are printed on one sheet in consideration of the print attributes at the time of previous printing. Thereby, it is possible to easily replace a corrected document page from a document printed by double-sided printing or N-up.
The print attribute refers to a page data printing method for one sheet. Specifically, the print attributes include the number of page data to be printed on one side of a sheet of paper (N-up), the print side (double-sided printing, single-sided printing), and the binding method during long-sided printing (long side binding, (Short side binding) This refers to information such as the arrangement order of page data printed on one sheet.

Further, in the above configuration, the extraction unit identifies a sentence file that was printed last time based on an attribute of the corrected sentence file for which a print request was made, and the corrected sentence file and the printed sentence file are It is possible to adopt a configuration in which page data of different parts is extracted as the modified page data.
With this configuration, even if the previously printed text file and the corrected text file are stored as different files, the corrected page data can be extracted with an easy operation.
The attribute of the text file refers to information unique to the text file. Specifically, the text file attributes include a text file name, text file creator, text file type, update date, creation date, and the like.

Further, in the above configuration, it is possible to employ a configuration including a storage unit that stores a printed text file and information related to printing attributes at the time of printing in association with each other.
With this configuration, the information about the print attributes at the previous printing can be held for each text file, so that the page data modified in consideration of the print attributes at the previous printing can be printed.

In the above configuration, it is possible to adopt a configuration in which the printed text file stored in the storage unit and the information related to the printing attribute at the time of printing are deleted after a predetermined period from the previous printing.
With this configuration, it is possible to prevent the storage area of the printing system from being occupied by a text file that is not scheduled to be printed or modified in the future.

Further, in the above configuration, a configuration including a notification unit that notifies the user that a print attribute different from the print attribute set at the previous printing is set can be adopted.
With this configuration, the user can prevent printing of page data modified with a print attribute different from the print attribute at the time of previous printing. Thereby, the corrected original page can be replaced with certainty.

  Further, the object is to extract, from the digitized text file in which a plurality of page data adjacent to each other is printed on one sheet, the page data whose contents are corrected from the time of printing, and the correction. Print for printing the page data and the uncorrected page data printed on the paper adjacent to the corrected page data on a single sheet in consideration of the print attributes at the time of printing And the step of creating data.

  With this configuration, a part of page data of a document printed based on printing attributes such as double-sided printing and N-up is corrected, and page data adjacent to the corrected page data is not corrected. In this case, the corrected page data and the uncorrected page data are printed on one sheet in consideration of the print attributes at the time of previous printing. Thereby, it is possible to easily replace a corrected document page from a document printed by double-sided printing or N-up.

  Further, the object is to extract, from the digitized text file in which a plurality of page data adjacent to each other is printed on one sheet, the page data whose contents are corrected from the time of printing, and the correction. Print for printing the page data and the uncorrected page data printed on the paper adjacent to the corrected page data on a single sheet in consideration of the print attributes at the time of printing It can also be achieved by a program for causing a computer to execute the step of creating data.

  With this configuration, a part of page data of a document printed based on printing attributes such as double-sided printing and N-up is corrected, and page data adjacent to the corrected page data is not corrected. In this case, the corrected page data and the uncorrected page data are printed on one sheet in consideration of the print attributes at the time of previous printing. Thereby, it is possible to easily replace a corrected document page from a document printed by double-sided printing or N-up.

  According to the present invention, it is possible to provide a printing system and a printing method capable of easily replacing a corrected document page for a document using double-sided printing or N-up.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of a printing system according to the present invention.
As shown in FIG. 1, a printer (printing system) 100 is connected to a client terminal 200 via a bus line. The printer 100 executes printing in accordance with print data and a print command transmitted from the client terminal 200.
The printer 100 includes a controller 110 and a printer engine 120.

The controller 110 includes an I / F 111, a CPU (Central Processing Unit) 112, a ROM (Read Only Memory) 113, a RAM (Random Access Memory) 114, an HDD (Hard Disk Drive) 115, and the like.
The HDD 115 stores printed text files and the like.

FIG. 2 is a diagram illustrating a functional configuration of the printer 100.
The controller 110 includes a reception unit 130, an extraction unit 140, a print attribute processing unit 150, a notification unit 160, a print data creation unit 170, and an HDD 115.
The receiving unit 130 receives a text file for which a print request has been made.
The extraction unit 140 determines the identity and commonality with the text file, and extracts the corrected page data. Details will be described later.
The print attribute processing unit 150 determines whether or not the print attribute of the text file for which the print request has been made is the same as the print attribute set at the previous printing.
The notification unit 160 notifies the user that the print attribute of the text file requested to be printed is different from the print attribute set at the previous printing.
The print data creation unit 170 creates predetermined print data. Details will be described later.
The functions of the reception unit 130, the extraction unit 140, the print attribute processing unit 150, the notification unit 160, and the print data creation unit 170 are realized by the CPU 112, the ROM 113, the RAM 114, and the like described above.

FIG. 3 is a diagram illustrating an example of a printed text file stored in the HDD 115. Each printed text file is associated with a file attribute, a print attribute, a print date and time, and the like. As file attributes, file name, creator of the text file, creation date and time, update date and time, and the like are stored. As printing attributes, printing surface, N-up, page data arrangement order, binding position at the time of duplex printing, and the like are stored. With these pieces of information, it becomes possible to extract modified page data, which will be described later.
Note that the text file stored in the HDD 115 is deleted after a predetermined period from the printing date. Along with this, the file name associated with the text file, the creator of the text file, the creation date / time, the print attribute, the print date / time, and the like are also deleted. As a result, a text file that has passed a predetermined period from the previous printing date and time is deleted from the HDD 115 as a text file that is not scheduled to be printed or modified in the future. Accordingly, it is possible to prevent the storage area of the printing system from being occupied by a text file that is not scheduled to be printed or modified in the future.
The print attribute refers to the number of page data to be printed on one sheet of paper and information on the surface to be printed. Specifically, it refers to information such as double-sided printing and N-up.

Next, processing executed by the controller 110 will be described. FIG. 4 is a flowchart illustrating an example of processing executed by the controller 110.
The receiving unit 130 receives a text file for which a print request is transmitted from the client terminal 200 (step S1).
Based on the attributes of the text file for which a print request has been made and the printed text file stored in the HDD 115, the extraction unit 140 can identify the same text file that has been requested for printing and the text file that has already been printed. The sex is determined (step S2).
In addition, the determination method of identity is determined based on the attribute of a text file. For example, it is determined from the text file type, creation date / time, creator, and update date / time.

  If the text file for which the print request has been made is a printed text file, the extraction unit 140 extracts page data whose contents have been modified since the previous printing from the text file for which the print request has been made (step S3). ). This is because the corrected page data is printed. Specifically, the corrected page data is extracted from the text file for which the print request is made by comparing the text file for which the print request is made with the printed text file.

  Next, the extraction unit 140 determines whether there is modified page data (step S4). If there is modified page data, the print attribute processing unit 150 selects the text file for which the print request has been made. It is determined whether or not the printing attribute is the same as the printing attribute set at the previous printing (step S5). This is because, by printing with the same attribute as the printing attribute at the previous printing, it is possible to easily replace the corrected document page from the document created at the previous printing.

  When the print attributes are the same, the print attribute processing unit 150 updates the printed text file stored in the HDD 115 to the text file requested to be printed, and the date and time when the printed text file was printed. Is updated to the current date and time when the print request is made (step S6).

  Next, the print data creation unit 170 creates print data (step S7). Specifically, if the page data printed on the paper adjacent to the page data before correction at the previous printing is uncorrected page data, the page data after correction and the page data before correction Print data for printing the uncorrected page data printed on the paper at the time of the previous printing adjacent to the image on one sheet in consideration of the print attributes at the time of the previous printing.

  Thereby, even when a part of page data is corrected in the original printed based on the print attribute such as double-sided printing or N-up, and the page data adjacent to the corrected page data is not corrected. The corrected page data and the uncorrected page data are printed on one sheet in consideration of the print attributes at the time of previous printing. Thereby, it is possible to easily replace a corrected document page from a document printed by double-sided printing or N-up.

  In addition, when the page data printed on the paper adjacent to the page data before correction at the time of the previous printing is also corrected, the print data creation unit 170 converts the page data after correction adjacent to each other, Print data for printing on one sheet is created in consideration of print attributes at the time of previous printing.

  Next, the print data creation unit 170 outputs the print data created in step S to the printer engine 120, and executes printing (step S8). As described above, it is possible to easily replace the corrected document page for the document using duplex printing or N-up.

  Next, in step S2, if the text file for which the print request has been made and the text file that has already been printed do not have the same identity, the extraction unit 140 is based on the file name of the text file for which the print request has been made. Then, the printed text file having the commonality with the text file requested for printing is specified (step S9). Specifically, if the file name of a text file for which a print request has been made is similar to the file name of a text file that has already been printed, it is determined that there is commonality. This commonality may be determined by other methods, for example, from the text file type, creation date / time, creator, and update date / time.

  When there is commonality, the extraction unit 140 identifies the sentence file for which the print request has been made as the corrected sentence file, and the page data of the difference between the printed sentence file and the corrected sentence file, Extracted as corrected page data (step S3). Thus, even if the previously printed text file and the corrected text file are stored as different files, the corrected page data can be extracted by an easy operation.

If there is no commonality in step S9, the print attribute processing unit 150 stores in the HDD 115 the text file, the file name, the print attribute, and the print date / time for which the print request has been made (step S10). This is because when the text file requested to be printed this time is corrected, it is possible to print only the corrected page data. Next, the print attribute processing unit 150, the print data creation unit 170, and the printer engine 120 print the text file requested for printing as usual (step S11).
Note that the reason why the printing date and time is stored in step S10 is that, as described above, a sentence file that has passed a predetermined period from the printing date and time is deleted.

If the print attribute of the text file requested to be printed in step S5 is different from the print attribute set at the time of the previous printing, the notification unit 160 outputs a client terminal 200 signal to notify the user to that effect. Then, a message indicating whether to print with the currently set print attribute or to cancel printing is displayed on the display of the client terminal 200 (step S12).
With this configuration, the user can prevent printing of page data modified with a print attribute different from the print attribute at the time of previous printing. Thereby, it is possible to reliably replace the corrected page.

Next, based on the signal from the client terminal 200, the notification unit 160 determines whether to print with different print attributes depending on the user's selection (step S13).
When printing with different print attributes according to the user's selection, the print attribute processing unit 150 updates the text file to the text file currently requested for printing, updates the print attribute to the currently set attribute, and sets the print date and time. Update (step S14), issue a command to the printer engine 120, and print as usual (step S11).
When printing is canceled due to the user's selection, the print attribute processing unit 150 deletes the requested print job (step S15).

  If there is no corrected page data in step S4, the print attribute processing unit 150 updates the print attribute and the print date and time (step S16), and prints normally (step S11). This is because when there is no corrected page data, the entire text file is printed again.

Next, a printing method of the printer 100 will be conceptually described.
FIG. 5 is a conceptual diagram for explaining a printing method of the printer 100.

The printed text file d includes page data 1d to 6d.
The printing attribute of the document p printed based on the printed text file d is two-sided up. Accordingly, page data 1d and 2d are printed on one side of the original page 1p. Similarly, page data 3d and 4d are printed on the original page 2p, and page data 5d and 6d are printed on the original page 3p.
The corrected text file D requested to be printed includes uncorrected page data 1d, 2d, 4d to 6d, and corrected page data 3D. The corrected page data 3D corresponds to the page data 3d before correction.

As described above, the extraction unit 140 extracts the modified page data 3D from the text file D requested to be printed by comparing the text file D requested to be printed with the text file d printed. To do.
Next, the extraction unit 140 corrects the page data 3D after correction, the uncorrected page data 4d printed on the paper adjacent to the page data 3d before correction at the previous printing, and the printing at the previous printing. Considering the attribute (single side 2 up), print on one sheet. Thereby, it is possible to obtain the document 2P on which the corrected page data 3D and the uncorrected page data 4d are printed.
Thereby, the document P printed this time can be easily replaced from the document p printed last time.

  Next, a printing system according to the second embodiment will be described with reference to FIG. The same parts as those of the printing system in the first embodiment are denoted by the same reference numerals, and redundant description is omitted. FIG. 6 is a schematic diagram of a printing system according to the second embodiment.

The server 300 is connected to the client terminal 200 and the printer 100a via a bus line.
The server 300 includes an I / F 311, a CPU 312, a ROM 313, a RAM 314, an HDD 315, and the like.
The HDD 315 stores printed text files and the like.
In addition, the CPU 312, the ROM 313, the RAM 314, and the like realize a reception unit, an extraction unit, a print attribute processing unit, a notification unit, and a print data creation unit that are similar to the functions of the printer according to the first embodiment.

  The server 300 receives the text file data requested for printing transmitted from the client terminal, and extracts a corrected page from the text file. After extraction, print data is created and output to the printer 100a. Thus, unlike the printer 100 of the first embodiment, the server 300 creates print data and outputs the print data to the printer 100a. As a result, the amount of data transmitted to the printer 100a can be reduced.

  In addition, the said Example is only an example for implementing this invention, This invention is not limited to these, It is within the scope of the present invention to modify these Examples variously, and this It is obvious from the above description that various other embodiments are possible within the scope of the invention.
