Print Job Intermediary for Unapproved Printer Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When printing with a printer not connected to or not approved by an information processing system, specific processes such as history management, authorization, and confidentiality are not available.
Innovation Solution
An information processing system that accepts a print request, executes predetermined processes, and transmits the print request to a preregistered information processing terminal, which then forwards it to the printer, enabling printing even with unconnected or unapproved printers through spooling and short-range wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If printing is performed with a printer not connected to or not approved by the information processing system, then printing flexibility and mobility are improved, but system security and process control deteriorate
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the information processing system and the printer. The mobile terminal receives print jobs from the system, processes them through short-range wireless communication, and transmits to the printer. This intermediary approach allows printing with unconnected or unapproved printers while maintaining system security, as the mobile terminal acts as a trusted bridge that can operate independently from direct printer connections.
2Ease of operation
If print requests are transmitted directly to unconnected printers, then operation simplicity is improved, but availability of specific processes deteriorates
Solution Approach 1:
The patent implements preliminary action by having the mobile terminal store print jobs locally after receiving them from the information processing system. The print jobs are processed and prepared in advance, with authentication and authorization completed before transmission to the printer. This allows the system to maintain security processes while enabling simple operation, as users only need to initiate printing from the mobile terminal without complex system configurations.
3Adaptability or versatility
If a mobile terminal is used as an intermediary for print job transmission, then process availability is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by enabling the mobile terminal to autonomously handle print job processing, storage, and transmission. The mobile terminal independently manages authentication, authorization, and communication with the printer without requiring continuous system intervention. This self-service capability reduces the operational burden on users and simplifies system management, offsetting the initial complexity of introducing an intermediary device.

AI summary
An information processing system includes a processor configured: to accept a print request including print information to be printed and execute one or more predetermined specific processes on the print information included in the accepted print request; and transmit the print request including the print information after execution of the one or more specific processes to a preregistered information processing terminal that is to transmit the print request to a printer.
