Description

[0001]
BACKGROUND OF THE INVENTION
The present invention provides a print image processing for performing control to continuously print a plurality of pages on a single print medium each when a long page and a wide page are mixed in one document. Relates to the device.
[0002]
[Prior art]
An application that creates a document including characters, images, and other various information does not necessarily create only a document that is printed only on a certain size paper of a certain size. For example, a document may be created in which the first few pages are portrait format pages, the middle portion includes a landscape format page, and the portrait format page continues.
[0003]
A portrait is a type of portrait page, which corresponds to an A4 size portrait page in the Japanese standard. A landscape is a type of landscape page, which corresponds to an A4 size landscape page in Japanese standards. As described above, even when a portrait page and a landscape page are mixed, when printing is performed separately on one sheet of paper, the printer driver automatically performs portrait and landscape conversion and continuous printing. Is possible.
[0004]
[Problems to be solved by the invention]
By the way, the conventional techniques as described above have the following problems to be solved.
When printing a document with a printer, there is a method of printing two pages side by side on a single sheet. In such a case, for example, two portrait-format pages are each reduced to a half area, and two portrait pages are printed side by side on one portrait-format page. Such printing is also called bag binding printing. The document created by the application is edited by the printer driver and supplied to the printer.
[0005]
However, in a document in which a portrait format page and a landscape format page are mixed as described above, when the portrait format page is continuous, a process of printing two pages on one sheet is executed. When the page was switched from portrait format to landscape format, the paper that had been printed so far was ejected, and the following landscape format pages were printed on new paper two by two. .
[0006]
Thus, for example, if there are three portrait-format pages and this is followed by one landscape-format page, when two pages are printed on one sheet, the first page is a portrait-format page. Two pages are printed, the next page is printed with one portrait page, and the last page is printed with one landscape page. Accordingly, a blank portion that is not printed for one page occurs in the middle of the two pages. Since the process of printing a plurality of pages on one sheet is performed for the purpose of saving the sheet to be printed, such control for leaving a blank portion that is not printed is not preferable.
[0007]

[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described using specific examples.
<Specific example 1>
FIG. 1 is a block diagram of the apparatus of the first specific example.
In the figure, a print document 2 output by an application 1 is configured to be input to a graphic device interface 3. The output of the graphic device interface 3 is configured to be output to the printer 6 via the printer driver 4.
[0012]
The printer driver 4 includes an image generation processing unit 4a, an array conversion processing unit 4b, a vertically long image buffer 4c, a horizontally long image buffer 4d, and a data transmission processing unit 4e. Hereinafter, a case where the application 1 of the host device (not shown) generates the document 2 composed of a plurality of pages and requests the printing thereof will be described. The application 1 outputs drawing data for printing the document to the graphic device interface 3 together with the print request command.
[0013]
Here, as shown in the figure, it is assumed that the print document 2 is composed of three vertically long pages, that is, portrait-type pages 2a, 2b, and 2c, and one horizontally long page, that is, a landscape-type page 2d. The graphic device interface 3 is a part that performs processing for converting a graphic drawing function that the application 1 calls to print the print document 2 into an output that depends on the output device. The output device is the printer 6. The printer driver 4 is a part that receives the drawing data and generates image data for printing. The image data generated in this way is stored in the print data editing unit 5 in an edited state.
[0014]
The application 1, the graphic device interface 3, the printer driver 4, and the like are configured by, for example, an interface program that operates with the OS (operating system) of the personal computer, and the print data editing unit 5 is expanded on the storage device of the personal computer. It is a storage area.
[0015]
Assume that the printer driver 4 and the printer 6 are connected to each other by an interface cable (not shown). The image generation processing unit 4a provided in the printer driver 4 generates image data corresponding to each page of the print document from the drawing data output from the graphic device interface 3, and stores the image data in the vertical image buffer 4c or the horizontal image buffer 4d. This is the part that performs processing. Note that the image is enlarged or reduced as necessary. The vertically long image buffer 4c and the horizontally long image buffer 4d are composed of storage areas for storing image data for one page. Note that the vertically long image buffer 4c and the horizontally long image buffer 4d are not used at the same time, and thus share the same storage area.
[0016]
In this example, the image data of each page 2a, 2b, 2c, and 2d of the print document 2 that is sequentially input to the printer driver 4 is stored in the vertical image buffer 4c or the horizontal image buffer 4d, and each of these two pages is stored one by one. Control to print on other paper. The print data editing unit 5 shows the paper images 5a and 5d. Two pages 5b and 5c in portrait format are allocated to the paper image 5a, and a page 5e in portrait format and a page 5f in landscape format are allocated to the paper image 5d.
[0017]
The data transmission processing unit 4 e is a part that performs control for sequentially reading out the print data stored in the print data editing unit 5 and transferring it to the printer 6. Data reading in this case is sequentially performed for each line from the top to the bottom of the paper images 5a and 5d. One line is a bit string in the horizontal direction (main scanning direction) of a vertically long paper image. Therefore, it is necessary to store the image data of each page in the print data editing unit 5 in this order. However, the image data arrangement differs between the portrait format data and the landscape format data.
[0018]
Conventionally, when a document in which a portrait format page and a landscape format page are mixed is printed as a set of two pages, for example, the portrait format page is reduced and rearranged into a landscape format, and then one line at a time. The data is transferred to the print data editing unit 5 and stored. When the print target is switched to a landscape page, the paper that has been printed is discharged. Next, the operation of reducing the landscape format page and transferring it to the print data editing unit 5 in order line by line is started. That is, the portrait format page and the landscape format page are not printed together on the same sheet.
[0019]
In the present invention, by using the array conversion processing unit 4b shown in the figure, even when pages of different formats coexist, these pages can be printed on one sheet of paper. The array conversion processing unit 4b is a part that, when the portrait format page data is input, converts the layout data into landscape format page data and outputs the data. In addition, when landscape page data is input, it is a part that performs a process of converting the data into a portrait page data and outputting it. As will be described later, this array conversion process is a process in which portrait-format page data is cut vertically by one line and arranged in the horizontal direction to generate landscape-format page data. Since such an array conversion process itself is widely known in the conventional image processing technology, a detailed description of its operation is omitted.
[0020]
FIG. 2 is a schematic diagram for explaining the operation of the apparatus according to the first specific example.
First, the portrait-format page 2c shown in the figure is arranged so that data is processed line by line in the direction of the arrow in order from the top, similarly to the other portrait-format pages 2a and 2b. In the figure, each line is displayed as a ruled line on each page. First, the portrait-format page 2c is converted into image data 2g that has been reduced to 1 / √2 in the vertical and horizontal directions. The array conversion processing unit 4b shown in FIG. 1 generates the converted image data 5e shown in FIG. 2 by cutting out the image data 2g one line at a time from the left end in the direction of the arrow. The image data 5e is sequentially read out in the direction of the arrow line by line from the top and pasted on the paper image 5d.
[0021]
On the other hand, the page 2d in the landscape format is data in a format that is sequentially read out line by line from the top as shown in FIG. This is reduced to 1 / √2 both vertically and horizontally in the same manner as a portrait page, and image data 5f is generated. The image data 5f is image data in a format that is read out line by line in the direction of the arrow. Therefore, they are read out in this order as they are and pasted on the paper image 5d.
[0022]
The image data 5e, 5f on the paper image 5d edited in this way is read out line by line from the top by the data transmission processing unit 4e and transferred to the printer. By performing such processing, a document in which portrait and landscape format pages are mixed can be continuously printed on each sheet of paper two pages at a time without any gap.
[0023]
FIG. 3 shows a detailed operation flowchart of the apparatus of the first specific example as described above. First, the application 1 shown in FIG. 1 classifies the generated print document 2 for each page and supplies it to the graphic device interface 3 for each page. When the printer driver 4 receives drawing data for one page from the graphic device interface 3, the drawing data is converted into image data in the image generation processing unit 4a. At this time, first, the parameter n shown in FIG. 3 is set to “1” (step S1). This n is a parameter for counting pages in the document.
[0024]
In step S2, the read drawing data is converted into image data by the image generation processing unit 4a. Next, in step S3, the printer driver 4 obtains a reduction ratio for the image data generated by the image generation processing unit 4a and performs a reduction process (step S4). Here, it is determined whether the page is a portrait format (step S5).
[0025]
If it is the portrait format, the process proceeds to step S6, and the reduced image data is stored in the portrait image buffer 4c. In step S7, the array conversion processing unit 4b performs array conversion into the landscape format as described with reference to FIG. In step S8, the converted image data for one page is edited in the data editing unit 5 and then transmitted to the printer as described later with reference to FIG.
[0026]
If the image data to be reduced is not a portrait, the process proceeds from step S5 to step S9, and the reduced image data is stored in the horizontally long image buffer 4d. In step S10, the image data for one page is edited in the data editing unit 5 and then transmitted to the printer. In the next step S11, it is determined whether the last page has been processed.
[0027]
If the last page has not been processed, the process proceeds to the next step S12. Then, it is determined whether or not the page is an even page process. When printing two pages on a single sheet, when printing of even pages is finished, a process of feeding a new print sheet, that is, a process of discharging a sheet printed by the printer 6 is performed. The printer driver 4 transmits a paper discharge command for that purpose to the printer (step S13). In the case of odd page processing, such processing is not necessary, and the process jumps to step S14.
[0028]
In step S14, n is incremented and processing proceeds to the next page. That is, returning to step S2, the drawing data of the next page is read again. When the process is finished up to the last page, the process proceeds from step S11 to step S15, a paper discharge command is transmitted, and all the processes are finished.
[0029]
FIG. 4 shows a flowchart of the image data transmission operation in step S8 or step S10 of FIG.
First, in step S1, it is determined whether n is an even number or an odd number. The processing is divided between the case where n is an even number and the case where n is an odd number because the allocation positions on the paper image 5a or 5d of the print data editing unit 5 shown in FIG. 1 are different. If n is an odd number, the process proceeds from step S1 to step S2, and the editing start point is designated as the upper left upper corner. That is, the point X1 on the paper image 5d in FIG. 2 is designated as the editing start point. In the case of an even page, the process proceeds to step S3, and the editing start point is designated at the lower left upper corner. That is, the point X2 on the paper image 5d shown in FIG. 2 is designated as the editing start point. In this way, the image data stored in the vertically long image buffer 4c or 4d is edited in the paper image 5a or 5d of the print data editing unit 5.
[0030]
Next, the image data for one sheet edited by the print data editing unit 5 is transmitted to the printer. In this case, it is determined whether the immediately preceding process is an even page process or an odd page process (step S4). If it is an odd-numbered page process, the image data of the next page is edited on the remaining half of the sheet and then printed, so the process exits this figure and proceeds to step S11 in FIG. When the processing of even pages is completed, image data transmission to the printer is started. First, the parameter m is set to “1” (step S5), and data reading for the m-th line is executed (step S6). That is, image data for one sheet is sequentially transferred to the printer 6 in order from the first line of the print image 5a or 5d in the print data editing unit 5.
[0031]
In step S6, it is determined whether m is “1”. In the case of the first line, print information is transmitted in advance to the printer (step S7). The print information is control information for designating the type of print medium and designating the margin of the paper that is the print medium. In the case of the second and subsequent lines, this process is jumped, and the process proceeds to step S8 to transmit the m-th line data. In step S9, it is determined whether m is the final line. If it is not the final line, the process proceeds to step S10, and the process for the next line is performed. That is, by repeating the process from step S5 to step S10, the process of transmitting the image data in the print data editing unit 5 to the printer is executed for all lines. When the transmission of all lines is completed, the process of this figure is exited and the process proceeds to step S11 of FIG.
[0032]
The print image processing apparatus is configured by the graphic device interface 3, the printer driver 4, and the print data editing unit 5. Usually, the graphic device interface 3 and the printer driver 4 are configured by a computer program installed on the host device side. The print data editing unit 5 includes a data file storage area called a spooler on the host device side. However, software or hardware having functions equivalent to these may be provided on the printer side, or some functions may be arranged on the upper apparatus side and the remaining functions arranged on the printer side. May be.
[0033]
Further, in the above example, a case has been described in which a portrait page is a portrait and a landscape page is a landscape, and a document in which these are mixed is continuously printed on paper. However, the format and size of the portrait page or landscape page, the layout method and the number of pages allocated to a single print sheet, the type of print medium, and the like can be freely changed.
[0034]
In the above example, the drawing data is converted into image data, then the size is reduced, and then the data array is converted. However, the processing for converting the drawing data into image data and the size are changed. The reduction process and the data array conversion process may be performed simultaneously. Of course, the order of these processes may be changed appropriately.
The above points also apply to each specific example described later.
[0035]
<Effect of specific example 1>
As described above, when image data for printing is generated by the printer driver, for example, a set of two pages in a document is allocated to a print area on one printing medium, and the set If the image data array of any page included in the page is different from the image data array supplied to the printer when printing the page in the print area allocated on the print medium, the array Since the conversion processing unit converts the data array and performs editing, it is possible to continuously print a set of pages in which landscape and portrait pages are mixed on one printing medium.
[0036]
<Specific example 2>
FIG. 5 is a block diagram of the apparatus of the second specific example.
As shown in the print document 2 in FIG. 7, in the specific example 2, the first page, the second page, and the third page are landscape-format pages 2a, 2b, and 2c, and the fourth page is a portrait-format page 2d. The case control will be described. Although the configuration of the apparatus itself is the same as that of the first specific example, the contents of the image data allocated in the paper images 5a and 5d in the print data editing unit 5 are different.
[0037]
FIG. 6 is a schematic explanatory diagram of the operation of the apparatus of the second specific example.
The landscape-type page 2c shown in the center of the figure is arranged so that data is processed line by line in the direction of the arrow in order from the top, similarly to the other landscape-type pages 2a and 2b. In the figure, each line is displayed as a ruled line on each page. The landscape format page 2c is converted into image data 5e that has been reduced to 1 / √2 as it is in the vertical and horizontal directions. The image data 5e is image data in a format that is read out line by line in the direction of the arrow. Therefore, they are read in this order as they are and pasted on the upper half of the paper image 5d.
[0038]
On the other hand, the portrait-format page 2d is data in a format that is sequentially read out line by line from the top as shown in the upper part of the figure. This is reduced to 1 / √2 both vertically and horizontally in the same manner as a landscape page, and image data 2g is generated. The array conversion processing unit 4b shown in FIG. 1 generates the converted image data 5f by cutting out the image data 2g from the left end one line at a time in the direction of the arrow. The image data 5f is sequentially read in the direction of the arrow line by line from the top and pasted on the lower half of the paper image 5d.
[0039]
The image data 5e and 5f on the sheet image 5d edited in this way are read out line by line from the top by the data transmission processing unit 4e in FIG. 5 and transferred to the printer.
The operation of the entire apparatus and the transmission processing of the data edited by the print data editing unit 5 to the printer are almost the same as those already described with reference to FIGS.
[0040]
<Effect of specific example 2>
By performing the processing as described above, a document in which a portrait format page is mixed after a landscape format page can be continuously printed on each sheet of paper two pages at a time without any gap.
[0041]
  <Specific example 3>
  Figure 7 shows a specific example3It is a block diagram of the apparatus.
  In the third specific example, the first page, the second page, and the third page are the portrait format pages 2a, 2b, and 2c, and the fourth page is the landscape format page 2d, as in the first specific example. The control in the case where the origin coordinate for printing is at the lower left of the paper will be described. In Specific Example 1, the origin coordinate of the paper is set to the upper right of the paper. Therefore, in this specific example, the configuration of the apparatus itself is not different from that of the specific example 1, but the procedure of data array conversion is different from that of the specific example 1. The image data in the vertically long image buffer 4c in FIG. 7 is converted into a landscape format data by being rearranged in the direction opposite to that in the first specific example. Therefore, a storage area 1 for temporarily storing the image data is provided.
[0042]
  Figure 8 shows a specific example3It is operation | movement outline explanatory drawing of this apparatus.
  First, the portrait-format page 2c shown in the figure is arranged so that data is processed line by line in the direction of the arrow in order from the top, similarly to the other portrait-format pages 2a and 2b. In the figure, each line is displayed as a ruled line on each page. First, the portrait-format page 2c is converted into image data 2g that has been reduced to 1 / √2 in the vertical and horizontal directions. The array conversion processing unit 4b shown in FIG. 7 generates the converted image data 5e by cutting out the image data 2g from the right end one line at a time in the direction of the arrow. In the specific example 1, in this part, the image data is sequentially read from the left end and the array conversion process is performed. Specific example 3 has a different reading order. The image data 5e is sequentially read out in the direction of the arrow line by line from the top and pasted on the paper image 5d.
[0043]
On the other hand, the page 2d in the landscape format is data in a format that is sequentially read out line by line from the top as shown in FIG. This is reduced to 1 / √2 both vertically and horizontally in the same manner as a portrait page, and image data 5f is generated. The image data 5f is image data in a format that is read out line by line in the direction of the arrow. Therefore, they are read out in this order as they are and pasted on the paper image 5d.
[0044]
The image data 5e, 5f on the paper image 5d edited in this way is read out line by line from the top by the data transmission processing unit 4e and transferred to the printer.
The operation of the entire apparatus and the transmission processing of the data edited by the print data editing unit 5 to the printer are almost the same as those already described with reference to FIGS.
[0045]
<Effect of specific example 3>
By performing the above processing, a document containing both portrait and landscape pages is placed on each sheet of paper, with the origin coordinate for printing at the bottom left of the sheet. Can be printed continuously.
[0046]
  Specific Example 4>
  Figure 9 shows a specific example4It is a block diagram of the apparatus.
  In this specific example, similarly to the specific example 1, the first page, the second page, and the third page are portrait pages 2a, 2b, and 2c, and the fourth page is a landscape format page 2d. An operation for printing on one sheet will be described. During this processing, portrait-format image data 5c and 5d assigned to the upper right and lower right of the paper image 5a are temporarily stored in the storage area 1 for the convenience of editing processing.
[0047]
  Figure 10 shows a specific example4It is operation | movement outline explanatory drawing of this apparatus.
  First, in the portrait format page 2d shown in the upper part of the figure, data is arranged so that each line is processed in the direction of the arrow in order from the top. In the figure, each line is displayed as a ruled line on each page. The portrait-format page 2d is converted into image data 5d that has been reduced to 1 / √2 as it is in the vertical and horizontal directions. The image data 5d is image data in a format that is read out line by line in the direction of the arrow. Therefore, they are read out in this order as they are and pasted in the lower left area of the paper image 5a.
[0048]
On the other hand, the landscape-format page 2c is data in a format that is sequentially read line by line from the top, as shown in FIG. 2, like the other landscape-format pages 2a and 2b. This is reduced to 1 / √2 both vertically and horizontally in the same manner as a portrait page, and image data 2e is generated. The array conversion processing unit 4b shown in FIG. 9 generates the converted image data 5e by cutting out the image data 2e one line at a time from the left end in the direction of the arrow. The image data 5e is sequentially read out in the direction of the arrow line by line from the top and pasted in the lower right area of the paper image 5a.
[0049]
The image data 5b, 5c, 5e, and 5f on the paper image 5a edited in this way correspond to the image data 5e and 5f on the paper image 5a in the first to third examples. The data transmission processing unit 4e reads out one line at a time from the top and transfers it to the printer in the same manner as in the first to third examples.
[0050]
The operation of the entire apparatus and the transmission processing of the data edited by the print data editing unit 5 to the printer are shown in FIGS. 3 and 5 for transmitting the image data 5e and 5f on the paper image 5a of the first to third examples. This is almost the same as that described with reference to FIG. 3 moves from the position next to step S6 to the position next to step S9. That is, if the image data is landscape, conversion processing to portrait is performed. If the image data is a portrait, no array conversion is performed.
[0051]
Further, the determination of “even page?” In step S12 in FIG. 3 is a determination as to whether it is the fourth page of one sheet. The determination whether n in step S1 in FIG. 4 is an even number is a determination that n is some of 1 to 4. 3 instead of step S2 and step S3 in FIG. 3, if n is 1, the upper left corner of the paper, if 1 is 2, the upper right corner of the paper, if n is 3, the lower left corner of the paper, and if n is 4, the lower right corner of the paper. Steps for editing the image data are inserted into the. Since the other parts are not changed, a duplicate description is omitted.
[0052]
<Effect of specific example 4>
By performing the processing as described above, a document in which portrait format pages and landscape format pages are mixed can be continuously printed on each sheet of paper, four pages at a time.
[0053]
<Specific example 5>
FIG. 11 is a block diagram of the apparatus of the fifth specific example.
In this specific example, the first page, the second page, and the third page are landscape-format pages 2a, 2b, and 2c, the fourth page is a portrait-format page 2d, and the fourth page is a set. An output method when printing on one sheet will be described. In Specific Example 4, the origin coordinate of the paper is set to the lower left of the paper. In this example, control in the case where the origin coordinate of the paper is at the upper right of the paper will be described. When the processing of this specific example is performed, storage areas 1 and 2 for three pages for temporarily storing image data are provided for the sake of processing. The setting of these storage areas can be arbitrarily changed by reducing the image data, changing the arrangement, assigning the image onto the paper image, editing procedure, and the like.
[0054]
FIG. 12 is a schematic explanatory diagram of the operation of the apparatus of the fifth specific example.
First, in the portrait format page 2d shown in the upper part of the figure, data is arranged so that each line is processed in the direction of the arrow in order from the top. In the figure, each line is displayed as a ruled line on each page. The portrait-format page 2d is converted into image data 5d that has been reduced to 1 / √2 as it is in the vertical and horizontal directions. The image data 5d is image data in a format that is read out line by line in the direction of the arrow. Therefore, they are read out in this order as they are and pasted in the lower left area of the paper image 5a.
[0055]
On the other hand, the landscape-format page 2c is data in a format that is sequentially read line by line from the top, as shown in FIG. 2, like the other landscape-format pages 2a and 2b. This is reduced to 1 / √2 both vertically and horizontally in the same manner as a portrait page, and image data 2e is generated. The array conversion processing unit 4b shown in FIG. 9 generates the converted image data 5e by cutting out the image data 2e from the right end one line at a time in the direction of the arrow. This is the difference from Example 4. The image data 5e is sequentially read out in the direction of the arrow line by line from the top and pasted in the lower right area of the paper image 5a.
[0056]
The image data 5b, 5c, 5e, and 5f on the paper image 5a edited in this way correspond to the image data 5e and 5f on the paper image 5a in the first to third examples. The data transmission processing unit 4e reads out one line at a time from the top and transfers it to the printer in the same manner as in the first to third examples. The following processing is the same as in the fourth specific example.
[0057]
The operation of the entire apparatus and the transmission processing of the data edited by the print data editing unit 5 to the printer are shown in FIGS. 3 and 5 for transmitting the image data 5e and 5f on the paper image 5a of the first to third examples. This is almost the same as that described with reference to FIG. 3 moves from the position next to step S6 to the position next to step S9. That is, if the image data is landscape, conversion processing to portrait is performed. If the image data is a portrait, no array conversion is performed.
[0058]
Further, the determination of “even page?” In step S12 in FIG. 3 is a determination as to whether it is the fourth page of one sheet. The determination whether n in step S1 in FIG. 4 is an even number is a determination that n is some of 1 to 4. 3 instead of step S2 and step S3 in FIG. 3, if n is 1, the upper left corner of the paper, if 1 is 2, the upper right corner of the paper, if n is 3, the lower left corner of the paper, and if n is 4, the lower right corner of the paper. Steps for editing the image data are inserted into the. Since the other parts are not changed, a duplicate description is omitted.

<Effect of Specific Example 5>
By performing the processing as described above, a document in which portrait and landscape format pages are mixed can be continuously printed on each sheet of paper in four directions, with no gaps.
