Printing System Server Authentication Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing systems lack flexibility in system operations due to the use of the same authentication server for both storing and transferring print jobs, limiting their operational flexibility.
Innovation Solution
The printing system employs a server device that communicates with multiple printers, each with different authentication methods, allowing for flexible operations by using first and second authentication information to store and retrieve print jobs associated with user identification, enabling printers to authenticate and access print jobs independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same authentication server is used for storing and transferring print jobs, then system structure is simplified, but system operational flexibility is reduced
Solution Approach 1:
The patent divides the authentication function into separate authentication servers for different operations: one authentication server handles print job storage authentication, while another authentication server handles print job transfer authentication. This segmentation allows each authentication server to be optimized independently, improving system operational flexibility without significantly increasing overall system complexity.
2Adaptability or versatility
If multiple authentication methods are used for different printers, then system flexibility is improved, but authentication management complexity increases
Solution Approach 1:
The patent implements a universal authentication framework where multiple authentication servers can be used across different printers and operations. Each authentication server can handle multiple authentication methods (such as certificate-based authentication, password-based authentication, or biometric authentication), allowing the system to support diverse authentication requirements while maintaining a consistent authentication management approach.
3Reliability
If authentication is performed separately for each printer, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs authentication in advance during print job submission and storage. The client device authenticates with the first authentication server before the print job is stored, and the printer authenticates with the second authentication server before retrieving and executing the print job. This preliminary authentication approach ensures high authentication accuracy while reducing processing time during actual print operations, as the authentication credentials are already verified and cached.

AI summary
A printing system includes: a first printer; a second printer; a server device; and a client device. The first printer is configured to perform: receiving first authentication information; accessing, in response to determining that first authentication performed according to a first authentication method is successful, the server device using first account information; receiving, from the server device, a print job stored in association with user identification information included in the first authentication information; printing an image based on the print job. The second printer is configured to perform: receiving second authentication information including the user identification information; accessing, in response to determining that second authentication performed according to a second authentication method is successful, the server device using second account information; receiving, from the server device, the print job stored in association with the user identification information; and printing the image based on the print job.
