Printer Job Owner Identification via Wireless Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing apparatuses cannot determine the job owner of print data received from mobile terminals, as user information is not included in the transmitted data, unlike from personal computers, leading to difficulties in managing print jobs and user authentication.
Innovation Solution
The printing apparatus includes a wireless local area network interface with a direct wireless function for communication with mobile terminals, a memory, and a processor that determines the user logging into the apparatus as the job owner by authenticating through an IC card or user input, allowing user management and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If print data is transmitted from a mobile terminal using direct wireless communication, then the printing apparatus can receive print data without a printer driver, but the printing apparatus cannot determine the job owner because user information is not included in the transmitted data
Solution Approach 1:
The printing apparatus performs user authentication and obtains user information before receiving print data. The processor authenticates the user via IC card or user input, and stores the obtained user information in advance. When print data is received from a mobile terminal, the processor retrieves the pre-stored user information to identify the job owner, thus resolving the information loss issue while maintaining mobile terminal compatibility
2Measurement precision
If user authentication is implemented through IC card or user input, then the printing apparatus can accurately identify the job owner, but the device complexity increases due to additional authentication components and processes
Solution Approach 1:
The printing apparatus uses existing user authentication mechanisms (IC card readers or user input interfaces) that are already present in the device. The processor leverages these existing components to obtain user information, rather than introducing entirely new authentication hardware. This approach maintains high identification accuracy while minimizing additional device complexity by reusing existing self-service authentication capabilities

AI summary
A printing apparatus determines a user who is logging into the printing apparatus as a job owner in a case where the printing apparatus receives print data through wireless communication in an access point mode.
