Printer Software Extension for Device-Specific Interfaces and Functions

The patent uses a standard driver that can be universally applied to multiple printing apparatuses from different vendors. This standard driver serves as a universal interface that maintains compatibility across various devices while providing a consistent user experience. The standard driver includes a spooler that can handle different print formats and communicate with various printing apparatuses through standardized protocols.

The patent introduces an extension application as an intermediary layer between the standard driver and the printing apparatus. This extension application receives print instructions from the standard driver, processes them according to the specific capabilities of the target printing apparatus, and forwards appropriately formatted instructions to the device. This intermediary enables customized functionality without compromising the universality of the standard driver.

The standard driver is designed to be universally installable on multiple printing apparatuses without requiring vendor-specific drivers. It includes a spooler that can automatically detect and adapt to different printing devices, eliminating the need for complex installation procedures. The standard driver comes with basic print functions built-in, and additional functions can be added through extension applications.

The extension application is designed to work preliminarily with the standard driver, adding extended functions before the actual printing process. The extension application can pre-process print instructions, add specialized functions (such as stamping, form filling, or document assembly), and then pass the enhanced instructions to the standard driver for execution. This preliminary action enables extended functionality while maintaining the simplicity of the standard installation process.

The patent segments the printing system into distinct functional components: the standard driver handles universal printing operations, the extension application manages device-specific customization, and the spooler coordinates between them. This segmentation allows each component to focus on specific tasks, reducing overall system complexity while enabling sophisticated device-specific settings through the extension application layer.

The extension application acts as an intermediary that translates generic print instructions from the standard driver into device-specific commands. It receives standardized print tasks, processes them according to the target printing apparatus's capabilities and requirements, and generates appropriate control instructions. This intermediary approach maintains simple driver configuration while enabling sophisticated device-specific customization.
