Description

  The present invention relates to an information processing apparatus, an information processing method, and a computer-readable program for generating a print job to be output to an image forming apparatus capable of bookbinding with cover.

  There is software called a printer driver as software for performing image forming processing from an application operating on an operating system (hereinafter referred to as “OS”) to a printer or the like. In this printer driver, a document created by the application is printed on one side. / There is a function to output in various output forms including duplex printing. Among these functions, there is a bookbinding function (which is referred to as “case binding”) in which the contents of a plurality of printed sheets are wrapped with a single sheet as a cover (front cover and back cover).

  In this case binding, as the cover sheet, a sheet having a size twice the size of the sheet constituting the contents is used, and the cover sheet is equally divided into two areas. A front cover is assigned, a back cover is assigned to the other area, and then printed. Then, the cover sheet is folded in two, and the contents are wrapped and stapled. Such a case binding machine exists as an offline binding machine different from the printing apparatus.

  In addition, a printing apparatus that prints a print job from a host computer and a printer driver that operates in the host computer have advanced functions. In recent printer drivers, detailed settings for bookbinding printing can be performed through the user interface, and the cover page In addition, it is possible to set whether or not to perform printing on the back, back cover, and back cover (for example, Patent Document 1).

  When performing case binding (bookbinding with cover) according to the present embodiment, the user sets the following items. That is, first, the user selects a tab labeled “Finishing” in the setting window of the user interface screen provided by the printer driver as shown in FIG. 3, and then labeled “Printing Method”. Select “wrap and book print” from the text selection field. Then, by pressing a “bookbinding details” button arranged on the right side of the option, a setting window labeled “bookbinding details” is called. An example of the called setting window is shown in FIG. The user then sets the number of content pages in the field labeled “Page Count” in the setting window labeled “Bookbinding Details” as shown in FIG. From the attached text selection field, the paper type constituting the contents is selected, and the size of the cover paper is entered in the text entry field labeled “paper size”.

  FIG. 5 is a flowchart showing an example of a print processing program as a printer driver stored in the program ROM of the ROM 3 in FIG. 1 or the external memory 11. The user sets the size of the paper to be used for printing, and sets the number of content pages, the paper type constituting the content, and the size of the cover via the setting windows in FIGS. 3 and 4. When printing based on the print data and the content print data is instructed from the operation system (hereinafter referred to as OS) to the printer driver (S51), first, it is determined whether the print mode is the duplex printing mode or the simplex printing mode. Based on this determination result, the number of sheets Sn constituting the contents is calculated from the number of pages Pn set from the setting window shown in FIG. 4 (S52). That is, when the printing mode is the duplex printing mode, calculation is performed from Sn = ceil (Pn / 2). However, ceil (x) is a function that rounds up the first decimal place of x. On the other hand, if the printing mode is the single-sided printing mode, Sn = Pn.

  Further, the thickness of the paper corresponding to the set paper type is acquired from a table in which the paper type and the paper thickness stored in the data ROM of the ROM 3 are associated (S53). Then, the spine width is calculated by multiplying the acquired paper thickness by the number of papers already obtained (S54).

  Then, the printer driver saves the print data input from the application software via the OS in the RAM 2 of FIG. 1 in units of pages (S55). Thereafter, in the virtual cover shown in FIG. 6, the spine cover area 62 having the spine width calculated in S54 is allocated to the center, and the center right side has the same size as the size of the paper used for printing. A front cover area 61 is allocated, and a back cover area 63 having the same size as the paper used for printing is allocated on the left side of the center (S56), and the cover printing stored in the RAM 2 is assigned to each of these areas. Data (ie, front cover print data, back cover print data, and back cover print data) is assigned (S57). Next, the cover print data assigned to each area is sent from the host computer 3000 to the printer 1500 via the bidirectional interface 21, and the printer 1500 uses the cover cover, back cover, and back cover based on the cover print data. Printing on the original paper (S58).

  It is assumed that the cover paper and the content paper are fed as instructed by the paper feed stage designation by the printer driver.

  The above allocation processing may be performed by spooling all data as a unique spool processing by the printer driver, or may be performed on the printer 1500 side, and may be performed by receiving information on the spine width from the printer driver. good.

  In the present embodiment, an example in which the printer 1500 is connected to the host computer 3000 via the bidirectional interface 21 has been described. However, the printer 1500 is connected to the host computer 3000 via a network such as a LAN or WAN. Even in this case, the printing process can be performed in the same manner.

<Second Embodiment>
In the present embodiment, the items set by the user are different from those in the first embodiment, and when performing case binding according to the present embodiment, the user sets the following items. That is, first, the user selects a tab labeled “Finishing” in the setting window as shown in FIG. 7, and then selects “wrapping booklet printing” from the text selection field labeled “Printing method”. This invokes a settings window labeled “Bookbinding Details”. An example of the called setting window is shown in FIG. Then, the user selects the paper type constituting the contents from the text selection field labeled “paper type” in the setting window labeled “bookbinding details” as shown in FIG. In addition, the size of the cover paper is entered in the text entry field labeled “paper size”.

  Further, the present embodiment differs from the first embodiment in the items set by the user, and therefore the case binding processing method is different. FIG. 9 is a flowchart showing an example of a print processing program stored in the program ROM of the ROM 3 of FIG. 1 in the present embodiment. When the size of paper to be used for printing is set, setting is performed from the setting window of FIGS. 7 and 8, and printing is executed (S91), first, print data (cover print data and content print data) is stored. The number of pages is stored in the RAM 2 in units of pages (S92), the number of pages is counted, and the number of sheets of content is calculated based on the counted number of pages, the duplex printing mode, and the simplex printing mode (S93). That is, when the mode is the duplex printing mode, the content number Sn is Sn = {(Pc, where Pc is the number of pages counted and Cn is the number of front cover, back cover and back cover. -Cn) / 2}. In the double-sided printing mode, for example, when the counted page number Pc is 11 pages and the cover print data is only the front cover print data and the back cover print data, the number of sheets constituting the contents is Sn = ceil {(11-2) / 2} = 5. On the other hand, when the mode is the single-sided printing mode, the number Sn of the contents is obtained from Sn = Pc−Cn. In the single-sided printing mode, for example, similarly, when the counted page number Pc is 11 pages and the cover print data is only the front cover print data and the back cover print data, the number of sheets constituting the contents is Sn = 11-2−9.

  Further, the thickness of the paper corresponding to the set paper type is obtained from a table in which the paper type and the paper thickness stored in the data ROM of the ROM 3 are associated (S94). Then, the spine width is calculated by multiplying the acquired paper thickness by the number of papers already obtained (S95). Then, in the virtual cover shown in FIG. 6, the spine cover area 62 having the spine width calculated in S95 is assigned to the center, the cover cover area 61 is assigned to the center right, and the back cover is assigned to the center left. The area 63 is allocated (S96), and the cover print data (that is, the cover cover print data, the back cover print data, and the back cover print data) stored in the RAM 2 is allocated to each of these areas (S97). Next, the cover print data is sent from the host computer 3000 to the printer 1500 via the bidirectional interface 21, and the front cover, the back cover, and the back cover are printed on the cover paper based on the cover print data. (S98).

  It is assumed that the cover paper and the content paper are fed as instructed by the paper feed stage designation by the printer driver.
