Print Job Redirection via Device Capability Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in finding and redirecting print jobs to alternative printing devices due to lack of information about available devices and their capabilities, leading to issues like paper jams or device unavailability.
Innovation Solution
A method and apparatus for print job redirection that provides users with options based on printing device capabilities, allowing for mandatory and desirable preferences, determining if a print job requires forwarding, and automatically forwarding the job to a suitable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user sends a print job to a printing device, then the print job can be processed, but the user may find the device down, having paper jams, or having many print jobs ahead, requiring redirection to another device
Solution Approach 1:
The printing device automatically performs redirection by evaluating its own status and the status of other devices in the network, selecting an appropriate alternative device without requiring user intervention. The system monitors its own operational state (down, paper jam, queue length) and autonomously redirects print jobs to suitable alternatives.
Solution Approach 2:
The system continuously monitors the operational status of printing devices and uses this feedback information to determine when redirection is needed. Status information about device availability, queue length, and operational state is collected and used to make real-time redirection decisions.
2Adaptability or versatility
If the user wants to forward the print job to another printing device, then the print job can be processed on a different device, but the user will not know which other printing devices are available and will not know which features are offered by the other printing devices
Solution Approach 1:
The system pre-gathers and maintains information about available printing devices and their capabilities before the user needs to redirect a print job. Device status, queue length, and feature capabilities are collected in advance and made available to the redirection system, eliminating the need for users to query device information at the moment of redirection.
Solution Approach 2:
The printing device acts as an intermediary that collects and processes information about networked printing devices. It maintains a database of available devices, their capabilities, and current status, then uses this information to automatically select and redirect print jobs to appropriate devices without requiring users to manually search for device information.
3Ease of operation
If the printing device provides detailed information about other printing devices and their capabilities, then the user can make informed redirection decisions, but the system complexity increases
Solution Approach 1:
The printing device automatically handles the complex task of gathering, processing, and using device capability information without requiring users to interact with complex systems. The redirection logic is encapsulated within the printing device itself, which autonomously evaluates device status and selects appropriate alternatives based on pre-collected information.

AI summary
An apparatus and method for print job redirection is disclosed. The method can include providing print job forwarding preference options. The print job forwarding preference options can include options for print job preferences based on printing device capabilities. The method can include receiving print job forwarding preferences at a printing device. The print job forwarding preferences can include at least one mandatory print job preference that specifies a mandatory printing device capability for a specific print job and at least one desirable print job preference that specifies a desirable printing device capability for the specific print job. The method can include determining whether the specific print job requires forwarding from the printing device to another printing device. The method can include forwarding the specific print job for printing if the specific print job requires forwarding.
