Printer Document Editing via Format Conversion and Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for changing document attributes in printers only allow for modifying processing attributes such as security, delay, and format, but do not enable editing or converting documents created in different formats or applications.
Innovation Solution
A device and method that allows users to edit documents stored on a printer or terminal by selecting and modifying individual units of documents, such as pages or paragraphs, to create new documents, using a network printer system with a control unit, input unit, and display unit to facilitate copying, deleting, and combining document units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional document attribute change methods are used in printers, then processing attributes (security, delay, format) can be modified, but editing or converting documents created in different formats or applications is not enabled
Solution Approach 1:
The invention segments document editing into two distinct functional modules: a document conversion module that handles format conversion between different application formats and a printer module that handles printing and basic attribute changes. This segmentation allows the system to support multiple document formats without requiring the printer itself to have complex document creation and editing capabilities, thus resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The invention introduces a computer as an intermediary device between the document creation environment and the printer. The computer performs document conversion from various formats to printer-compatible formats and prepares documents for printing, while the printer focuses on its core function of printing. This intermediary approach enables format compatibility without adding complexity to the printer system.
2Adaptability or versatility
If users want to edit documents created in different formats, then document versatility is improved, but the requirement for additional editing functions increases device complexity
Solution Approach 1:
The system segments document editing operations into format conversion (performed by the computer's conversion module) and printing operations (performed by the printer). This allows users to edit and convert documents in their familiar computer environment using appropriate software, then send the converted documents to the printer for printing, maintaining ease of operation while supporting multi-format documents.
3Reliability
If the printer includes security authentication function, then secure document printing is enabled, but the device complexity increases
Solution Approach 1:
The invention implements a universal authentication mechanism where the printer's control panel provides a standardized interface for security authentication that works across different document types and sources. The authentication function is integrated into the existing control panel structure, allowing the printer to handle secure documents from various formats and sources through a single, unified security system, thus providing reliable security without proportionally increasing device complexity.
