Print-Time GUI Control for V4 Printer Driver Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The V4 printer driver in Windows® lacks customizability, particularly in providing a graphical user interface (GUI) and accessing drawing data, limiting the functionality of Windows Store Device Apps (WSDA) in extending printer driver functions.
Innovation Solution
An at-time-of-printing start application is introduced to provide a GUI and access drawing data, determining the need for a user interface based on printer driver capabilities and settings, and enabling user operations to be reflected in the printing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V4 printer driver architecture is used to improve security and simplify driver structure, then driver security and ease of operation are improved, but the ability to provide GUI and access drawing data deteriorates
Solution Approach 1:
The patent introduces a configuration module as an intermediary component that bridges the V4 printer driver and the user interface. This module receives drawing data from the host computer, processes it according to printer settings, and generates appropriate print commands. The configuration module acts as a mediator that enables GUI functionality and drawing data access without compromising the security architecture of the V4 driver, effectively resolving the contradiction between security and adaptability.
2Device complexity
If V4 printer driver architecture is used to simplify driver structure, then device complexity is reduced, but the functionality of Windows Store Device Apps in extending printer driver functions deteriorates
Solution Approach 1:
The patent segments the printer driver functionality into distinct modules: the core V4 driver handling basic print operations, a configuration module for processing drawing data and managing printer settings, and Windows Store Device Apps for providing extended functionality. This segmentation allows each component to operate independently with well-defined interfaces, maintaining structural simplicity while enabling functional extensibility through the configuration module's drawing data access capabilities.
3Ease of operation
If standard class driver is used to improve convenience and reduce installation requirements, then ease of operation is improved, but the ability to provide customized printing functions deteriorates
Solution Approach 1:
The patent applies local quality by enabling the configuration module to access and process drawing data locally on the host computer before transmission to the printer. This local processing capability allows customized printing functions to be implemented without requiring separate driver installations, as the configuration module can be configured with specific printing requirements while using the standard class driver framework, thus maintaining both convenience and customizability.
Data Source
AI summary
A control method for an information processing apparatus which comprises a memory that stores a graphical user interface (GUI) application capable of providing a GUI in a case where a driver that does not have a function of providing a GUI is selected, the control method includes causing the GUI application to acquire drawing data generated by a drawing application, acquiring, by the GUI application, at least either of data including information indicating a setting and data including information indicating a capability of the driver, and providing, the GUI application, a first display item.
