Economic Printing Mode Font Modification Ink Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and time consumption in manually adjusting print settings to reduce printing ink consumption, as existing methods require manual modifications to documents and print settings.
Innovation Solution
A computer system implements an economic printing mode by transforming source printing content into target content with lower ink consumption through selectable levels for print quality, image information, and textual information modifications, providing automatic transformations and ink consumption estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If manual adjustments are made to reduce ink consumption (deleting words, adjusting paragraph settings, reducing images), then ink consumption is reduced, but user convenience and time efficiency deteriorate
Solution Approach 1:
The system performs automatic ink optimization without requiring user intervention. The processor automatically analyzes the document, identifies ink-consuming elements, and applies optimization techniques (such as converting images to grayscale, removing redundant whitespace, optimizing font rendering) to reduce ink consumption while maintaining document readability and layout integrity.
Solution Approach 2:
The patent replaces manual mechanical adjustments (user manually deleting words, adjusting settings) with an automated computational system. The processor uses algorithms to automatically analyze and optimize the document's ink consumption characteristics, substituting human manual operations with automated digital processing.
2Loss of substance
If manual adjustments are made to reduce ink consumption (modifying document content and print settings), then ink consumption is reduced, but time consumption increases
Solution Approach 1:
The system performs ink optimization automatically during the printing preparation phase, before the user initiates the print job. The processor pre-analyzes the document, identifies optimization opportunities, and applies reductions in ink consumption automatically, so that when the user sends the document to print, the optimization is already complete and no additional time is required from the user.
Solution Approach 2:
The system autonomously performs the time-consuming task of ink optimization without requiring user involvement. The automated processor handles document analysis, optimization strategy selection, and implementation entirely on its own, eliminating the time users would otherwise spend manually adjusting settings.
3Loss of substance
If automatic transformations are applied to reduce ink consumption, then ink savings increase and user effort decreases, but control over document appearance may be reduced
Solution Approach 1:
The system applies different optimization strategies to different elements within the document based on their specific characteristics. For example, it may apply grayscale conversion only to certain image types, optimize font rendering selectively, or adjust spacing locally in specific sections. This localized approach allows ink reduction while preserving the critical visual qualities of different document elements.
Solution Approach 2:
The optimization system is designed to be adaptive and configurable. Users can adjust optimization parameters and select which types of transformations to apply, allowing the system to dynamically adapt between maximum ink savings and maximum document fidelity based on user preferences and specific document requirements.

AI summary
Example methods and systems to implement an economic printing mode with font information modification are described. In one example, a computer system may obtain source printing content associated with a print job that is destined for a printer and the economic printing mode may be selected for the print job. The computer system may extract, from the source printing content, (a) textual information to be printed and (b) font information associated with the textual information. The source printing content may be transformed to generate target printing content that is printable using a lower ink consumption compared to the source printing content by modifying the font information associated with the textual information. The computer system may provide the target printing content that includes modified font information to the printer for printing and/or generate a preview of the target printing content prior to printing using the printer.
