Print Job Name Modification for Pass-Through Mode Identification

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing document management systems lack the ability to efficiently identify and manage print jobs that utilize the pass-through print mode, leading to potential mismatches in color spaces and printing issues when converting between formats like PDF and GDI, which can result in unsatisfactory print quality.

Innovation Solution

An information processing apparatus that includes a printer driver and a digital frontend, which upon receiving a print instruction, obtains and modifies the print job name according to a predetermined rule, and processes document data in a pass-through print mode by adding or removing identifiers to indicate the print mode, ensuring proper handling and display of print jobs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system uses pass-through print mode to output document data directly without processing, then printing speed is improved, but color space mismatches and printing quality issues occur

Engineering Contradiction:

Improveprinting speedVSAvoidprinting quality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The patent introduces an intermediary mechanism (the processor that adds/removes identifiers and the manager that handles print jobs) to mediate between the pass-through print mode and the color management system. This intermediary ensures color space consistency is maintained even when direct pass-through printing is used, resolving the contradiction between printing speed and quality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the system does not modify print job names, then system complexity is reduced, but the ability to identify and manage pass-through print jobs deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidprint job identification capability

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent applies local quality by modifying only specific portions of the print job name (adding or removing identifiers indicating pass-through mode) rather than completely changing the naming system. This localized modification provides necessary identification capability while minimizing the increase in system complexity.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the system converts between PDF and GDI formats, then compatibility is improved, but color space mismatches and processing time increase

Engineering Contradiction:

Improveformat compatibilityVSAvoidprocessing time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing the pass-through print mode identification through identifier modification before the actual printing process. This allows the system to prepare color space conversion parameters in advance, reducing real-time processing time while maintaining format compatibility.

Inventive Principle:

Principle #10Preliminary action

AI summary

An information processing apparatus includes a unit that, upon receiving from an application a print instruction for outputting document data to an image forming apparatus for printing without performing a process on the document data, obtains a print job name relating to the document data and changes the print job name in accordance with a predetermined rule.
