Abstract

Defect-free printing is achieved by previewing on a display prior to printing, device functions and print specifications. Preview of double-sided faces is concurrently provided when double-sided printing is specified. Display is performed by generation of data which allows print preview that reflects consideration of device information and document data. Data is generated for perspective-reverse-face preview when page-specification information is set for double-sided faces.

Claims

1. An information-processing apparatus for displaying a preview image based on document data generated by an application, comprising:

a setting unit constructed to set double-sided printing;

a designation unit constructed to designate a display of the preview image;

a data-generating unit constructed to generate an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by setting unit and said designation unit designates the display of the preview image; and

a display controlling unit constructed to display a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image;

wherein said display controlling unit displays the merged preview image so that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.

2. The information-processing apparatus according to claim 1, further comprising a specification unit for specifying whether perspective-reverse faces are previewed or only obverse faces are displayed when previewing is performed for the document data for which the specification is set,

wherein, when said specification unit specifies that only the obverse faces are displayed, said data-generating unit generates the obverse face preview image for pages to be placed on the obverse face of the sheet.

3. The information-processing apparatus according to claim 2, wherein said specification unit specifies one of an even-number page and an odd-number page to be an obverse face, and said data-generating unit generates the obverse face preview image by assuming the specified page to be the obverse face.

4. The information-processing apparatus according to claim 1, further comprising a spooling unit for receiving the document data via a rendering unit controlled by an operating system and retaining the document data as intermediate data, wherein said data-generating unit generates rendering data from the intermediate data retained by said spooling unit and re-outputs the rendering data to said rendering unit.

5. The information-processing apparatus according to claim 4, further comprising a print-data generating unit for converting the rendering data inputted via said rendering unit controlled by said operating system to print-data that can be interpreted by said printer.

6. The information-processing apparatus according to claim 5, further comprising a transmitting unit for transmitting the print-data to said printer via a network, the print-data having been converted and generated by said print-data generating unit.

7. The information-processing apparatus according to claim 6, wherein the previewing can be started before spooling of all logical pages.

22. The information-processing apparatus according to claim 1, wherein said display controlling unit displays the merged preview image on which the perspective-reverse-face preview image is reversed.

a setting step of setting double-sided printing;

a designating step of designating a display of the preview image;

a data-generating step of generating an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by setting step and said designation step designates to display the preview image; and

a display controlling step of displaying a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image;

wherein said displaying controlling step displays the merged preview image so that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.

9. The information-processing method according to claim 8, further comprising a specification step of specifying whether perspective-reverse faces are previewed or only obverse faces are displayed when previewing is performed for the document data for which the specification is set,

wherein, when said specification step specifies that only the obverse faces are displayed, said data-generating step generates the obverse face preview image for pages to be placed on the obverse face of the sheet.

10. The information-processing method according to claim 9, wherein

said specification step specifies one of an even-number page and an odd-number page to be an obverse face, and

said data-generating step generates the obverse face preview image by assuming the specified page to be the obverse face.

11. The information-processing method according to claim 8, further comprising a spooling step of receiving the document data via a rendering step controlled by an operating system and retaining the document data as intermediate data, wherein said data-generating step generates rendering data from the intermediate data retained by said spooling step and re-outputs the rendering data to said rendering step.

12. The information-processing method according to claim 11, further comprising a print-data generating step of converting the rendering data inputted via said rendering step controlled by said operating system to print-data that can be interpreted by said printer.

13. The information-processing method according to claim 12, further comprising a transmitting step of transmitting the print-data to said printer via a network, the print-data having been converted and generated in the print-data generating step.

14. The information-processing method according to claim 13, wherein the previewing can be started before spooling of all logical pages.
