Web Page Area Selection and Printing Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in printing web pages as most are designed without consideration for completeness, leading to omitted information or undesired pages being printed, and existing applications restrict selections by treating web page portions as HTML objects with stack structures.
Innovation Solution
A host apparatus and method that allows users to select and edit desired areas of a web page by capturing and editing regions on the page, displaying them in a separate area for editing, and printing or saving them as full-screen images without the restrictions of HTML object structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If web browser printing function is used, then printing operation is simple, but information may be omitted or undesired pages are printed due to partial printing cut
Solution Approach 1:
The system performs preliminary actions by automatically generating a preview image showing exactly how the web page will be printed before the user commits to printing. This allows users to see the complete printed result including all margins, headers, footers, and page breaks, enabling them to adjust print settings in advance to prevent information omission or unwanted printing.
2Loss of information
If web browser edit function is used to adjust margin, orientation, head, tail, then information omission is prevented, but user has difficulty in ascertaining whether printing is performed as desired
Solution Approach 1:
The system creates a visual copy (preview image) of the exact printed output that will be produced. This preview image is displayed to the user before printing, allowing them to verify that margins, orientation, headers, and footers are correctly configured without needing to interpret complex print settings. The preview serves as a direct visual representation of the final printed result.
3Adaptability or versatility
If applications for selecting web page portions are used, then specific areas can be selected, but selections are restricted by HTML object stack structure and undesired portions may be selected
Solution Approach 1:
The system replaces the mechanical HTML object stack structure with an image-based selection approach. Instead of being constrained by HTML DOM hierarchy and object stacking contexts, users can freely select any visual area on the web page by interacting with the rendered image. The system captures the selected visual area and processes it accordingly, eliminating the restrictions imposed by HTML's structural constraints.

AI summary
A host apparatus connected with an image forming apparatus and a web page printing method thereof. The method of printing a displayed web page includes capturing at least one area on the displayed web page, displaying the at least one captured area in a first area disposed adjacent to the displayed web page, editing the at least one captured area displayed in the first area, and executing the at least one captured and edited area. With this, it is convenient for a user to select, edit and print a desired area from a web page.
