Printer Driver Interlocking Mechanism for Monochrome Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current printer drivers lack efficient mechanisms to manage print data output between color and monochrome image forming apparatuses, leading to potential image quality deterioration and increased processing burdens when converting color images to monochrome, especially when the application program generates print data without interlocking settings.
Innovation Solution
The printer driver incorporates an interlocking setting mechanism that allows it to determine whether the color setting is interlocked with the application program, and if not, it generates and processes monochrome image data by converting color images within the printer driver, thereby avoiding unnecessary processing on the computer and maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application program generates print data without interlocking settings, then the printer driver must convert color images to monochrome, but this causes image quality deterioration and increased processing burden
Solution Approach 1:
The patent introduces an interlocking setting mechanism as an intermediary between the application program and printer driver. This setting allows the printer driver to determine whether color conversion should be performed, thereby mediating the conflict between maintaining image quality and reducing processing burden. When interlocking is enabled, the application program can control color settings directly; when disabled, the printer driver performs intelligent conversion based on the target device capabilities.
Solution Approach 2:
The patent implements preliminary action by establishing the interlocking setting configuration before print data generation occurs. This allows the system to pre-determine the color conversion strategy based on whether the application program or printer driver should control the color settings, preventing unnecessary processing burden and image quality deterioration from the outset.
2Reliability
If the printer driver converts color images to monochrome internally, then image quality is maintained, but processing time increases
Solution Approach 1:
The patent applies dynamics by making the color conversion process conditional rather than static. The interlocking setting allows the system to dynamically adjust whether color conversion is performed based on the specific printing scenario, target device capabilities, and user preferences. This dynamic approach prevents unnecessary conversion operations that would waste processing time while maintaining image quality when conversion is actually needed.
3Adaptability or versatility
If the color setting is not interlocked with the application program, then the printer driver has full control, but the application program cannot optimize print data generation
Solution Approach 1:
The patent implements preliminary action by establishing the interlocking setting configuration before print data generation occurs. This allows the system to pre-determine the color conversion strategy based on whether the application program or printer driver should control the color settings, preventing unnecessary processing burden and image quality deterioration from the outset.

AI summary
A computer, which executes a color machine driver for outputting print data generated by an application program for generating the print data to a color image forming apparatus, accepts an interlocking setting, which is a setting for whether a color setting which is a setting for causing the color image forming apparatus to execute color printing or monochrome printing is interlocked with the application program. In case that the color setting is set not to be interlocked with the application program in the interlocking setting, when the color setting in the color machine driver is a color setting that causes the color image forming apparatus to execute the monochrome printing, the computer causes the application program to generate print data for the color image, and executes a monochrome image forming process for converting the color image into a monochrome image.
