Virtual Printer GDI Document Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document transmission methods over networks require the recipient to have installed software associated with the document, leading to compatibility issues and inability to view documents without the correct applications.
Innovation Solution
Converting documents into GDI format through virtual printing, allowing recipients to restore and view documents without needing the original software, utilizing a virtual printer module for conversion and a restoration module for rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If documents are transmitted in their original format, then the document sender can maintain formatting and functionality, but the document receiver cannot view the document without the corresponding application installed
Solution Approach 1:
The patent introduces a virtual printer as an intermediary device that converts documents into a universal format (printer output format) that can be viewed by any system with a printer driver, eliminating the need for the original application software on the receiving end
Solution Approach 2:
The patent creates a copy of the document in the form of printer output data (GDI document), which contains all necessary formatting and content information in a standardized format that can be restored and viewed without the original application
2Adaptability or versatility
If documents are converted to PDF format, then the types of applications to be installed are reduced, but the document still cannot be read if the corresponding application is not installed
Solution Approach 1:
The virtual printer acts as a mediator that converts any document format into a universal printer output format (GDI document) that can be restored by any system with printing capabilities, ensuring both universality and readability
3Reliability
If the document receiver must have specific software installed, then document functionality is preserved, but the ease of operation and accessibility are reduced
Solution Approach 1:
The receiving system uses its own built-in printer driver to restore and view the document, eliminating the need to install external application software. The system serves itself using existing resources
Solution Approach 2:
The virtual printer document serves as an intermediary that bridges the gap between the original document and the receiving system, allowing the receiver to access documents using only standard printing capabilities

AI summary
The present invention discloses a method system for transmitting a document over a Network including the steps of a document sender converts a sharing document to be transmitted into a GDI (Graph Device Interface) document by performing virtual printing. The document receiver receives the graph device interface document sent from the document sender through the network The document receiver restores the received GDI document. The contents of the restored GDI document are the same as that of the sharing document. The present invention also provides a system, a virtual printer apparatus and a restoration apparatus, the transmission of the document is not restricted by the application using the method, system and apparatus of the present invention.
