Service Linking Server for Cross-System Print Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to allow users to download and print data registered in a server when the device installed in a store operates as a different system from the server that registered the print data.
Innovation Solution
An integrated printing system comprising a first print management server, a second print management server, and a service linking server, where the first print management server issues job identification information including issuance source information, the service linking server manages this information, and the second print management server acquires and executes print processing based on the identified print data from the first print management server when instructed by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If print data is registered in a server and users attempt to print at a store, then printing functionality is provided, but when the store device and server operate as different systems, the user cannot download and print the registered print data
Solution Approach 1:
The patent introduces a service linking device as an intermediary between the first print management server and the second print management server. This mediator acquires job identification information from the first server, manages it in its own database, and enables the second server to access print data through this bridging mechanism, thereby resolving the incompatibility between different print management systems
Solution Approach 2:
The service linking device performs multiple functions: it acts as a job information management server that stores and manages job identification information, serves as a translation layer between different print management systems, and enables universal access to print data across system boundaries, allowing any print management device to access print data from any server through the unified interface
2Adaptability or versatility
If a service linking device is introduced to enable cross-system printing, then adaptability between different print management systems is improved, but the system complexity increases
Solution Approach 1:
The patent extracts the complex cross-system coordination functionality into a separate service linking device, isolating the complexity from the core print management servers. This extraction allows the first and second print management servers to remain relatively simple while delegating the complex job information management and system bridging functions to the specialized service linking device
Solution Approach 2:
The service linking device creates a copy and centralized management of job identification information from the first print management server. By maintaining a replicated version of job information in its own database, the service linking device enables access without requiring direct connections between all system components, simplifying the overall architecture
Data Source
AI summary
An integrated printing system includes a first print management server, a second print management server, and a service linking server. When receiving a print instruction designating job identification information, the second print management server transmits job identification information to the service linking server. The service linking server includes a transfer control unit configured to acquire issuance source information included in the job identification information received from the second print management server and transfer, to the second print management server, print data corresponding to the job identification information stored by the first print management server indicated by the issuance source information.
