Supporting Program for Printer Image Sheet Size Conformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printer control technologies using OS-standard print programs often result in unintended print results due to size mismatches between images and printing sheets, leading to increased processing loads and potential paper waste, especially when using high-value sheets.
Innovation Solution
A supporting program that compares the size of an image to be printed with the sheet size in the print settings, warning the user through a user interface if a mismatch is detected, allowing for user intervention to adjust settings before printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the OS-standard general-use printing program is used without printer driver, then the ease of operation is improved, but the reliability of print results deteriorates due to size mismatch detection failure
Solution Approach 1:
The patent introduces a supporting program as an intermediary between the OS-standard printing program and the printer. This supporting program specifically detects size mismatches between images and sheets, compensating for the lack of specialized detection in general-use printing programs while maintaining ease of operation.
Solution Approach 2:
The supporting program performs preliminary detection of size mismatches before printing executes. By checking whether the image size matches the sheet size in advance and warning users beforehand, it prevents unreliable print results without requiring users to change their operating procedure.
2Reliability
If size mismatch detection is implemented, then the reliability of print results is improved, but the device complexity increases
Solution Approach 1:
The patent segments the printing system into multiple components: the OS-standard printing program for general control, and a dedicated supporting program for size mismatch detection. This segmentation allows the detection function to be added without complicating the core printing mechanism.
Solution Approach 2:
The supporting program acts as an intermediary layer that adds detection capability without modifying the OS-standard printing program or the printer hardware. This approach improves reliability while minimizing increases in overall system complexity.
3Productivity
If printing without size verification is performed, then the productivity is improved, but the loss of substance increases due to paper waste
Solution Approach 1:
The supporting program performs preliminary verification of image-sheet size compatibility before printing. By detecting mismatches in advance and warning users, it prevents paper waste without significantly slowing down the printing process, thus maintaining productivity while reducing substance loss.
Solution Approach 2:
The system provides feedback to users when a size mismatch is detected, allowing them to adjust settings before printing. This feedback mechanism prevents paper waste by enabling corrective action without requiring reprints, thereby reducing loss of substance while maintaining productivity.
Data Source
AI summary
In response to a print instruction instructing a printer to print an image being made with respect to a general-use printing program implemented in an operating system of the information processing device, the information processing device uses a supporting program to obtain an image size of print data subject to printing based on the number of vertical dots, the number of horizontal dots, and print resolution of the print data. Further, the information processing device obtains second size information indicating a sheet size included in a print setting and determines, by comparing the image size the sheet size, whether the sheet size conforms to the image size. When determining that the sheet size does not conform to the image size, the information processing device performs a warning process of displaying a warning message using a user interface.
