Print System Server Transmits Screen Information to Second Printer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print systems experience high communication loads due to the transmission and reception of print job data between management servers and multifunction peripherals, leading to inefficiencies and potential security risks.
Innovation Solution
A print system architecture where a server transmits screen information associated with print jobs to a second print apparatus, which displays the screen and receives print job data from a first print apparatus for execution, reducing direct communication between the server and the first print apparatus and enhancing security by preventing unauthorized printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the management server transmits and receives print job data before the multifunction peripheral executes printing, then the printing process can be managed centrally, but the amount of communication in the system becomes large
Solution Approach 1:
The patent extracts the print job data transmission from the global network communication path. Instead of transmitting print job data through the management server over the global network, the system stores print job data locally in the multifunction peripheral's storage unit. The server only transmits lightweight screen information (URLs, metadata) rather than the actual print data, dramatically reducing global network communication volume while maintaining centralized management capabilities.
Solution Approach 2:
The patent introduces a local storage unit in the multifunction peripheral as an intermediary between the terminal device and the management server. Print job data is stored locally in this intermediary storage, allowing the server to manage print jobs through screen information without requiring direct transmission of print data through the global network, thus reducing communication overhead.
2Extent of automation
If print job data is transmitted through the global network between server and print apparatus, then centralized control is achieved, but security risks increase due to unauthorized access potential
Solution Approach 1:
The patent extracts print job data from the global network transmission path and stores it locally in the multifunction peripheral. Only screen information (URLs, metadata) is transmitted through the global network, while the actual print data remains in the local storage unit. This extraction eliminates the security vulnerability of transmitting sensitive print data over the network while maintaining centralized control through server-managed screen information.
Solution Approach 2:
The patent performs preliminary storage of print job data in the multifunction peripheral's storage unit before any printing operation. By pre-storing the data locally and only transmitting screen information through the network, the system establishes a security barrier that prevents unauthorized access to print data during transmission, while still allowing centralized management through the server's control over screen information distribution.

AI summary
A print system includes a first multifunction peripheral, a second multifunction peripheral configured to communicate with the first multifunction peripheral, and a server configured to communicate with the first and second multifunction peripherals. The first multifunction peripheral receives print job data from a terminal device and stores the received print job data. The server transmits an HTML file of a screen for printing associated with printing based on the print job data to the second multifunction peripheral. The second multifunction peripheral displays, based on the HTML file of the screen for printing received from the server, the screen for printing and, when a print instruction operation is performed on the displayed screen for printing, receives the print job data stored in the first multifunction peripheral from the first multifunction peripheral and executes printing based on the received print job data.
