Metadata-Driven Print Job Format Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses face challenges in seamlessly integrating with diverse user devices and servers, particularly in handling various print job formats and protocols, leading to limitations in direct printing capabilities and user interface complexities.
Innovation Solution
The solution involves an image forming apparatus, user device, and server communication framework that generates and transmits metadata for print jobs, allowing the apparatus to determine the appropriate printing method based on format, with optional external conversion for unsupported formats, and enhancing user interface capabilities through interconnected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image forming apparatus supports multiple print job formats and protocols, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a metadata-based intermediary system that acts as a mediator between diverse print job formats and the image forming apparatus. The metadata contains format identification information and processing instructions, allowing the apparatus to handle multiple formats through a unified interface without requiring complex native support for each format, thus resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The image forming apparatus is designed with universal functionality to process various print job formats (such as PDF, JPEG, PNG, and other document formats) through a common metadata-driven architecture. This multi-functional capability allows a single device to perform multiple format conversions and printing operations without requiring separate specialized systems for each format
2Adaptability or versatility
If the image forming apparatus performs format conversion for unsupported formats, then the adaptability is improved, but the loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-defining metadata templates and conversion rules for various print job formats. The metadata structure is prepared in advance with format identification fields and processing instructions, allowing the apparatus to quickly determine the appropriate conversion path without performing complex format detection and analysis during the printing process, thereby reducing conversion time while maintaining broad format support
Data Source
AI summary
A user device generates metadata including location information of a print job target, based on a user input made via a user interface device, and transmits the generated metadata to an image forming apparatus. The image forming apparatus analyzes the metadata received from the user device via a communicator, obtains a print job target from a server storing the print job target, based on location information of the print job target included in the metadata, and performs a printing job according to a format of the obtained print job target.
