Printer Language Layer Selection for Direct Print
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multilingual files, such as PDFs, cannot be printed in the desired language using the direct print function, as the printer defaults to printing layers based on the default display setting, leading to unintended language printing.
Innovation Solution
A printer system that determines the print target layer by matching the language information from the printer's settings with the language layers in the document file, allowing the user to select and print the desired language layer even when the file is printed directly without viewer display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printer uses the default display setting to determine print target layers, then the printing process is simple and fast, but the printed language may not match the user's desired language
Solution Approach 1:
The printer acquires language information from an information source (such as printer settings or user input) and uses this feedback to determine which language layer to print. The system compares the acquired language information with the languages of available layers, and selectively prints the matching layer, ensuring the printed output matches the user's desired language while maintaining operational simplicity
Solution Approach 2:
The printer performs preliminary language matching before the actual printing process. By acquiring language information in advance and identifying the corresponding language layer beforehand, the system ensures that the correct language is printed without requiring complex user intervention during the printing process itself
2Manufacturing precision
If the printer prints all layers regardless of language matching, then all content is printed, but the file size and processing time increase unnecessarily
Solution Approach 1:
The printer extracts and identifies only the language layer that matches the acquired language information from the multiple layers in the document file. Instead of processing all layers, the system selectively extracts the relevant language layer for printing, reducing processing time and improving efficiency while ensuring complete printing of the desired language content
Data Source
AI summary
A printer includes a print engine, a processor, and a memory. The print engine is configured to print an image on a print medium. The memory stores instructions, the instructions, when executed by the processor, causing the printer to perform: in a case where a plurality of layers is included in a document file that is acquired from one of a storage medium connected to the printer and an apparatus configured to communicate with the printer, determining whether the plurality of layers includes a selection target layer that is a layer corresponding to a same language as a language indicated by language information acquired from an information source; in response to determining that the plurality of layers includes the selection target layer, determining a layer including the selection target layer as a print target layer; and controlling the print engine to print the print target layer.
