Printing System Physical Configurations for Job Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared printing systems, simultaneous usage by multiple groups leads to errors due to mixing of print jobs and difficulty in maintaining resource usage, especially when groups have separate accounts and are located remotely.
Innovation Solution
A controller configures and maintains distinct physical configurations of the printing system, ensuring each group has exclusive access to its input and output resources, preventing inter-group resource usage and job mixing, with a user interface limiting access to only relevant options for each group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the printing system is shared by multiple groups simultaneously, then the productivity and utilization of the printing system is improved, but the reliability deteriorates due to mixing of print jobs and errors
Solution Approach 1:
The printing system is divided into multiple isolated physical configurations, where each configuration is assigned to a specific user group. The controller creates separate paper paths and resource allocations for each group, preventing job mixing while allowing simultaneous usage. This segmentation resolves the contradiction by enabling multi-group productivity without compromising job accuracy.
2Ease of operation
If remote users access the printing system, then the ease of operation is improved, but the reliability worsens due to difficulty in maintaining resource usage and separate accounts
Solution Approach 1:
The controller acts as an intermediary that manages resource allocation and job routing between remote users and the printing system. It automatically assigns print jobs to the correct physical configuration based on user group credentials, eliminating the need for manual resource management. This intermediary function enables easy remote access while maintaining reliable resource usage through automated control.
3Reliability
If multiple physical configurations are created for different groups, then the reliability of print job separation is improved, but the device complexity increases
Solution Approach 1:
The controller provides universal management capabilities that handle multiple physical configurations through a single interface. It automatically routes jobs to appropriate configurations based on user credentials, and manages all configurations centrally without requiring separate management systems. This multi-functionality achieves reliable job separation while minimizing the operational complexity users experience.

AI summary
The present invention relates to a printing system (1) comprising a controller (37) for controlling the processing of print jobs, a plurality of input holders (44, 45, 46) for holding print media to be printed upon, a print engine for disposing marking material on the print media, and a plurality of output holders (51, 57) for holding the print media when the marking material has been disposed on the print media by the print engine and the print media is ready for taking out by an operator. The controller (37) is configured to establish and to maintain a plurality of physical configurations of the printing system (1). Each physical configuration comprises the print engine, at least one input holder (44, 45, 46) out of the plurality of input holders (44, 45, 46) and at least one output holder (51, 57) out of the plurality of output holders (51, 57). Each physical configuration is disjunctive from the at least one other physical configuration of the plurality of physical configurations with respect to the at least one input holder (44, 45, 46) of the at least one other physical configuration of the plurality of physical configurations and with respect to the at least one output holder (51, 57) of the at least one other physical configuration of the plurality of physical configurations. The invention also relates to a job submission device and a method for the printing system (1).
