Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printer drivers often malfunction, causing applications to crash or hang, and are specific to particular operating systems and processor architectures, leading to a large number of incompatible drivers in the market.
Innovation Solution
A printer user interface component is introduced to handle presentation of information to users during printing operations, decoupling core rendering and configuration functionality from user interface tasks, and allowing the component to be implemented as a standalone application or dynamic link library, enabling cross-process communication and compatibility with various operating systems and architectures.

Engineering Contradiction Analysis
1Ease of operation
If printer driver code is executed within the process of the application, then the application can directly invoke printer functions, but the application may crash or hang due to printer driver malfunction
Solution Approach 1:
The invention segments the printer driver functionality into separate processes: the application process and the printer driver process. The application process contains the application module, while the printer driver process contains the printer driver module. This segmentation allows the application to invoke printer functions through inter-process communication without executing printer driver code within the application process, thereby preventing crashes or hangs from propagating to the application.
Solution Approach 2:
The invention introduces an intermediary mechanism for communication between the application process and printer driver process. The application module communicates with the printer driver module through standardized interfaces and data structures, allowing function invocation without direct code execution. This intermediary layer isolates the application from printer driver malfunctions while maintaining operational capability.
2Productivity
If printer driver code is compiled prior to execution, then the printer driver is optimized for performance, but it becomes specific to a particular operating system and processor architecture
Solution Approach 1:
The invention creates a universal printer driver architecture that can function across multiple operating systems and processor architectures. The printer driver module is designed with platform-agnostic interfaces and configuration mechanisms, allowing it to adapt to different environments. The driver can be configured for specific platforms through parameters and settings rather than requiring separate compiled versions, achieving multi-functionality across diverse systems.
Solution Approach 2:
The invention uses parameter changes to adapt the printer driver to different operating systems and processor architectures. Instead of compiling separate versions for each platform, the driver accepts platform-specific parameters and configuration data at runtime. This allows a single compiled driver to function efficiently across multiple platforms by adjusting its behavior based on the target environment's characteristics.
3Manufacturing precision
If the number of different printer drivers in the marketplace is large, then each driver can be optimized for specific systems, but the complexity of driver management and compatibility increases
Solution Approach 1:
The invention reduces the number of printer drivers by creating a universal driver that can serve multiple operating systems and processor architectures. Instead of maintaining separate optimized drivers for each platform combination, a single driver implementation with configurable parameters achieves system-specific optimization dynamically. This universality reduces driver management complexity while preserving system-specific optimization capabilities.
Data Source
AI summary
Some embodiments of the invention provide a printer user interface (UI) component configured to handle presentation of information to a user during printing operations. The printer UI component may de-couple the rendering and configuration functionality provided by a printer driver from the presentation of information to end users, thereby reducing the risk that applications may crash or hang due to printer driver malfunction. In some embodiments, a registry of events upon which information should be presented to the user is established, and the printer UI component may be registered for some or all of these events, so that when the specified events occur the printer UI component may be invoked to cause information to be presented to the user.
