Printer Button Display Control for File Identification

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional printing apparatuses may inadvertently print a file different from the user's intended file due to reliance on setting histories without proper confirmation, leading to unintended printing.

Innovation Solution

A printing apparatus with a button display control unit to show character strings for identifying data and print settings, and a determination unit to ensure all character strings are displayed, prompting a notification screen if any part is not, preventing unintended printing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If printing is executed based on setting histories without displaying file identification information, then printing operation speed is improved, but printing accuracy deteriorates (wrong file may be printed)

Engineering Contradiction:

Improveprinting operation speedVSAvoidprinting accuracy

Core Design Contradiction:

Loss of timeVSManufacturing precision

Solution Approach 1:

The system performs preliminary display of file identification information on the setting call button before the printing operation. This allows the user to confirm the correct file is selected before initiating printing, preventing wrong file printing while maintaining efficient operation through pre-prepared identification display

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides visual feedback by displaying the file identification character string on the setting call button. This feedback mechanism allows the user to verify the file to be printed before execution, ensuring printing accuracy without sacrificing operational speed

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If file identification character string is always fully displayed on setting call button, then printing accuracy is improved, but device complexity increases

Engineering Contradiction:

Improveprinting accuracyVSAvoiddisplay control complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary assessment of whether the file identification character string can be fully displayed on the setting call button. If space is sufficient, the full string is displayed; if not, alternative arrangements are made. This preliminary check avoids unnecessary complexity while ensuring accuracy when possible

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system displays the file identification character string partially (truncated or abbreviated) when full display is not feasible, rather than implementing complex dynamic resizing or multi-line display mechanisms. This partial display approach maintains simplicity while still providing sufficient identification for user confirmation

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A printing apparatus which is capable of preventing printing from being performed based on setting histories against user's will. The printing apparatus displays a setting call button for calling data to be printed and print setting information. A character string for identifying the data is displayed on the setting call button. It is determined whether or not all of the character string is displayed on the setting call button. When a user has selected the setting call button on which at least a part of the character string is not displayed, a notification screen that prompts a user to confirm the data to be printed is displayed.
