Printer Controller Querying Print Engine for Dynamic Printmodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers lack a method to dynamically ascertain and utilize the supported printmodes by the print engine, limiting flexibility and user options, as existing systems require pre-programmed lists and are not adaptable to different print engines.
Innovation Solution
A querying component within the printer system queries the print engine to determine its supported printmodes, receiving a list that describes these modes, allowing flexible processing and user interface presentation, and enabling adaptation to various print engines without specific programming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pre-programmed printmode lists are used in existing printer systems, then the system structure is simple and easy to implement, but the system lacks flexibility and cannot adapt to different print engines
Solution Approach 1:
The print engine provides self-service by automatically generating and providing its own printmode list to the printer controller through querying mechanisms. This eliminates the need for the controller to have pre-programmed knowledge of specific print engine capabilities, allowing the system to adapt to different print engines while maintaining relatively simple architecture.
Solution Approach 2:
The querying component is designed with universal functionality to work with multiple different print engines. By implementing a standardized querying interface that can obtain printmode information from any print engine, the system achieves multi-engine compatibility without requiring engine-specific programming in the controller.
2Adaptability or versatility
If the printer controller stores pre-programmed printmode lists for each print engine, then it can provide comprehensive printmode options, but it requires specific programming for each print engine and cannot adapt dynamically
Solution Approach 1:
The system transitions from static pre-programmed printmode lists to dynamic querying where the printmode list is obtained on-demand. The querying component dynamically retrieves the current printmode list from the print engine, allowing the system to adapt to changes in print engine capabilities without requiring reprogramming or updates to the controller.
Solution Approach 2:
The printmode information is extracted from the print engine itself rather than being stored in the controller. By separating the printmode data storage from the controller and placing it in the print engine, the system eliminates the need for duplicate programming across different engine implementations.
3Ease of operation
If the system uses fixed printmode lists, then implementation is straightforward, but user flexibility and available options are limited
Solution Approach 1:
The querying component implements a feedback mechanism where the printer controller queries the print engine to obtain the current printmode list. This feedback loop ensures that the controller always has access to the most up-to-date information about available printmodes, providing users with comprehensive options while maintaining a relatively simple implementation through standardized querying protocols.
