Print Preview Magnification Slider for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printer drivers make it cumbersome for users to easily change and resume the display magnification factor of print previews, leading to difficulties in confirming page layouts and details, which deteriorates the usability of image forming apparatuses.
Innovation Solution
A computer executable program that allows users to intuitively change the display magnification factor using a slider and buttons, displaying magnification factors corresponding to various modes such as 'WHOLE PAGE', 'ADJUST WIDTH', and 'ADJUST HEIGHT', enabling easy resumption of the original magnification factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display magnification factor is changed using conventional menu buttons and keyboard operations, then the magnification can be adjusted, but the operating procedure becomes very complicated and cumbersome
Solution Approach 1:
The patent introduces a slider control that dynamically adjusts the display magnification factor through continuous movement, replacing discrete button presses with a fluid, intuitive sliding action. This dynamic interface allows users to smoothly transition between different magnification levels without navigating complex menus or remembering specific key combinations.
Solution Approach 2:
The slider acts as an intermediary control element between the user and the magnification factor setting. Instead of directly selecting from predefined magnification options through multiple menu levels, the slider provides a direct, visual, and continuous adjustment mechanism that simplifies the interaction process.
2Adaptability or versatility
If the display magnification factor is changed, then different viewing details can be confirmed, but it becomes difficult to resume the original magnification factor
Solution Approach 1:
The slider control provides visual feedback by displaying the current magnification factor and the relationship between different magnification settings. This feedback mechanism allows users to understand their current position and easily return to previous magnification levels by simply moving the slider back, without needing to remember complex restoration procedures.
Solution Approach 2:
The slider maintains a continuous record of magnification states, allowing users to return to original or previous magnification levels through simple reverse adjustment. The control interface preserves the relationship between different magnification settings, making resumption of original views a natural and intuitive action rather than a complex restoration process.
3Device complexity
If the print preview is displayed with fixed magnification, then the display is simple, but the user cannot easily confirm both overall layout and detailed content
Solution Approach 1:
The patent transforms the static, fixed magnification display into a dynamic, continuously adjustable system. The slider control enables users to smoothly transition between different magnification levels, allowing the same interface to serve both overview and detailed viewing needs without requiring multiple fixed display modes or complex configurations.

AI summary
Disclose is an image forming apparatus, which makes it possible to easily change the display magnification factor of the print preview image, by conducting intuitive operations. A print function setting section of the apparatus includes: a first designating section to accept a designation of a display magnification factor to be employed for displaying the print preview; a second designating section to accept a designation of a display mode; a magnification factor determining section to calculate display magnification factors; an image creating section to create the print preview, based on the display magnification factor designated by the first designating section, or another display magnification factor calculated by the magnification factor determining section; and a display controlling section to implement controlling operations for displaying the print preview, the slider and the buttons onto the display screen, indicating the current magnification factor and displaying a button corresponding to the fit page display mode.
