Printing System Server Data Transfer Removable Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing systems face challenges in preventing data leakage from removable media, as users often forget to remove these media after printing, and transferring all data to the printer's storage can burden the printer's capacity and reduce its performance.
Innovation Solution
A printing system comprising a printer and a server that communicates to transfer and store data from removable media, allowing selective data transfer based on priority and storage capacity, with the server acting as a secure storage area to prevent data leakage and alleviate printer storage burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all data is transferred from removable medium to printer storage, then data leakage risk is reduced, but printer storage capacity is burdened and performance deteriorates
Solution Approach 1:
The patent extracts the data storage function from the printer system and places it in an external storage device. The controller transfers data from the removable medium to the external storage device, which has sufficient capacity to hold all transferred data without burdening the printer's internal storage resources.
Solution Approach 2:
The patent introduces an external storage device as an intermediary between the removable medium and the printer. This mediator handles the data storage burden, allowing the printer to maintain its performance while still achieving data leakage prevention through the controlled transfer process.
2Reliability
If printer storage capacity is increased to accommodate all transferred data, then data leakage prevention is improved, but device cost and complexity increase
Solution Approach 1:
The patent extracts the large-capacity storage requirement from the printer system and assigns it to a separate external storage device. This allows the printer to maintain its original configuration without internal expansion while still achieving comprehensive data transfer capability.
Solution Approach 2:
The external storage device serves multiple functions: it provides large-capacity data storage, acts as a secure repository for transferred data, and can be connected to various printers without requiring modifications to the printer's internal architecture.
Data Source
AI summary
A printing system comprising a printing device and a server configured to perform data communication with the printing device. The printing device comprises a printing unit configured to print an image on a printing sheet, an attachment unit to which a removable medium is removably attached, a first communication interface configured to communicate with the server, and a first controller configured to acquire at least part of data in the removable medium attached to the attachment unit, control the first communication interface to transmit the acquired data to the server, delete the data in the removable medium corresponding to the acquired data. The server comprises a second communication interface configured to communicate with the printing device, a server-side storage configured to store the acquired data, and a second controller configured to store the acquired data received by the second communication interface in the server-side storage.
