Print Job Routing via Server or Printer Based on Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional print systems face inefficiencies in transmitting print jobs due to prioritization issues between servers and image forming apparatuses, particularly when network connectivity and job size are considerations, leading to suboptimal traffic management and potential delays.
Innovation Solution
A print job transmitting apparatus with a transmission destination confirming portion that prioritizes servers over image forming apparatuses when connected, but switches to image forming apparatuses for larger jobs or when server connectivity is lost, optimizing traffic by reducing network bandwidth usage and ensuring job execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the print job transmitting apparatus always transmits print jobs to the server when connected, then centralized job management is improved, but network bandwidth consumption increases and transmission speed decreases for large jobs
Solution Approach 1:
The system changes the transmission destination parameter dynamically based on job size. For large print jobs (exceeding a predetermined threshold), the system transmits directly to the image forming apparatus instead of the server, while smaller jobs continue to be routed through the server for centralized management.
Solution Approach 2:
The transmission destination is made dynamic rather than static. The system adaptively selects between server and image forming apparatus as the destination based on real-time conditions including job size, achieving optimal balance between centralized management and transmission efficiency.
2Loss of energy
If the print job transmitting apparatus prioritizes server transmission, then network traffic management is improved, but system availability deteriorates when server connectivity is lost
Solution Approach 1:
The system prepares alternative transmission paths in advance. When server connectivity is lost or unavailable, the system can immediately switch to transmitting print jobs directly to the image forming apparatus, preventing system failure and ensuring continuous operation.
Solution Approach 2:
The image forming apparatus serves as an alternative intermediary for job transmission. When the server intermediary is unavailable, the print job transmitting apparatus can directly communicate with the image forming apparatus, maintaining the transmission function through an alternative path.
3Reliability
If large print jobs are transmitted through the server, then centralized processing is improved, but network bandwidth consumption increases
Solution Approach 1:
The system changes the transmission parameter based on job size. For large print jobs exceeding a predetermined threshold, direct transmission to the image forming apparatus is selected to minimize network bandwidth consumption, while smaller jobs use the server path for centralized processing.

AI summary
In a print job transmitting apparatus, when the print job transmitting apparatus is communicably connected with a server configured to spool a print job, a transmission destination confirming portion prioritizes the server over an image forming apparatus and confirms the server as a transmission destination of the print job. When the print job transmitting apparatus is not communicably connected with the server and is communicably connected with the image forming apparatus, the transmission destination confirming portion confirms the image forming apparatus as the transmission destination, and even in a case where the print job transmitting apparatus is communicably connected with the server, when a size of the print job is greater than or equal to a specific size, the transmission destination confirming portion confirms the image forming apparatus as the transmission destination.
