Print Data Mediation for Indefinite-Length Sheet Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional OS-standard printing software does not support printer-specific settings for printing on sheets of indefinite length, leading to automatic reduction of image size when the print data exceeds the designated sheet size, resulting in unsatisfactory printing results.
Innovation Solution
An information processing device and program that modifies print data to size-reduced data when necessary, and upon request from a printer application, transmits original print data to ensure printing on sheets of indefinite length without reducing the image size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If OS-standard printing software automatically reduces image size when print data exceeds designated sheet size, then printing compatibility is improved, but printing precision deteriorates
Solution Approach 1:
The patent introduces an intermediary component between the OS-standard printing software and the printer that intercepts print jobs, detects when automatic size reduction has occurred, and retrieves the original print data to send to the printer instead. This mediator resolves the contradiction by preserving printing precision while maintaining compatibility with OS-standard software.
Solution Approach 2:
The system performs preliminary detection of print data characteristics before transmission to the printer. By analyzing whether the print data has been modified by automatic size reduction, the system can take preliminary action to retrieve the original data, thereby preventing precision loss before it occurs.
2Ease of operation
If printer driver is not used for driverless printing, then ease of operation is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements an intermediary layer that bridges the gap between driverless printing simplicity and printer-specific functionality. This intermediary component adds intelligence to the printing system, enabling it to detect when printer-specific features are needed and retrieve appropriate print data, thus providing adaptability without compromising ease of operation.
Solution Approach 2:
The system enables the printing apparatus to self-determine whether it needs original print data by analyzing the received print job characteristics. This self-service capability allows the printer to automatically adapt to different printing scenarios without requiring user configuration or driver installation, resolving the contradiction between ease of operation and adaptability.

AI summary
An information processing device includes a storage and a processor. The storage stores an information processing program supporting a printer. The processor executing the program receives specified print data from a standard printing software integrated in an operating system. The standard printing software performs a modification process modifying the original print data to size-reduced print data representing a size-reduced image when a size of an original image represented by original print data exceeds a designated sheet size of a printing sheet for printing. The specified print data is the original print data or the size-reduced print data. In response to reception of the specified print data, the processor executing the program transmits, to the standard printing software, a request for the original print data, receive the original print data from the standard printing software, and transmit, to the printer, finalized print data based on the original print data received.
