Preview Data Orientation Correction for Double-Sided Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional preview functions in printing systems struggle to accurately display print data orientation, particularly during double-side printing, making it difficult for users to recognize the printing result due to the need for vertical flipping or reversing of images based on device configuration and settings.
Innovation Solution
A computer program and information processing apparatus that acquires image data, determines if direction changes are needed based on double-side print settings, and generates preview data by reversing the image data accordingly, ensuring the orientation is correctly displayed for user recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the developed print data is displayed in preview as it is, then the preview function operates simply, but the vertically reversed print data is displayed which is difficult for a user to recognize the printing result
Solution Approach 1:
The patent applies inversion by detecting when print data has been vertically reversed for double-sided printing and then inverting it again for preview display. This restores the original orientation so users can recognize the printing result intuitively, while the actual print output remains correctly reversed for the printer
Solution Approach 2:
The patent introduces an intermediary processing step that creates a separate preview data stream from the print data. This intermediary process detects vertical reversal, applies corrective inversion, and generates preview data in the correct orientation without affecting the original print data flow to the printer
2Manufacturing precision
If the direction of image data is changed based on double-side print setting, then the printing orientation is correct, but the preview display shows reversed direction which causes confusion
Solution Approach 1:
The patent segments the data processing into two distinct paths: one for print data generation that applies vertical reversal according to double-sided printing settings, and another for preview data generation that detects the reversal and applies inverse correction. This segmentation allows both correct printing orientation and intuitive preview display to coexist
Solution Approach 2:
The patent changes the orientation parameter differently for print data versus preview data. For print data, the vertical reversal parameter is applied based on double-sided printing settings. For preview data, the system detects this parameter change and applies an inverse transformation, effectively canceling the reversal to restore the original image orientation for display purposes

AI summary
There is provided a non-transitory computer readable medium storing a program for a computer of an information processing apparatus, the program causing the computer of the information processing apparatus to carry out: acquiring an image data as a print object; generating a print data, which is an image data for printing, after determining whether or not to change a direction of the acquired image data based on a double-side print setting, and changing the direction of the image data in a case in which the image data is determined to change the direction; generating a preview data, which is an image data for previewing, from the print data after rechanging the once-changed direction of the image data in a case in which the print data is generated after changing the direction of the image data; and displaying the generated preview data onto the information processing apparatus.
