Print Control Apparatus Code System Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print control systems fail to correctly display characters and symbols input on a print control apparatus on a printing apparatus due to mismatched character code systems, leading to garbled characters, and require operators to manually match code systems, which is cumbersome and prone to errors.
Innovation Solution
A print control apparatus that requests and receives character code system information from the printing apparatus, allowing attribute information to be input using the received code system, ensuring that characters and symbols are displayed correctly by matching the input code system with the printing apparatus's code system, thereby avoiding garbled characters and simplifying operator interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the print control apparatus uses its own character code system for input, then the operator can input characters easily according to local habits, but the characters may be displayed as garbled on the printing apparatus due to code system mismatch
Solution Approach 1:
The print control apparatus automatically requests and receives character code system information from the printing apparatus before the input operation. The apparatus preliminarily acquires the target code system information and stores it, so that when the operator inputs characters, the correct code system is already prepared and automatically applied, eliminating the need for manual code system selection while preventing garbled character display
Solution Approach 2:
The print control apparatus acts as an intermediary between the operator's input and the printing apparatus's display. It receives character code system information from the printing apparatus and uses this information to automatically convert and transmit the input characters in the correct code system, serving as a mediator that translates between different code systems without requiring manual intervention
2Reliability
If the operator manually matches character code systems between PC and printer, then character display accuracy can be maintained, but the operation becomes cumbersome and error-prone
Solution Approach 1:
The print control apparatus performs self-service by automatically requesting and receiving character code system information from the printing apparatus. The apparatus independently acquires the necessary code system information and applies it without requiring operator intervention, thereby maintaining character display accuracy while eliminating the cumbersome manual configuration process
Solution Approach 2:
The system implements feedback by having the print control apparatus request character code system information from the printing apparatus and use this feedback information to automatically configure the input code system. This feedback mechanism ensures that the correct code system is automatically applied based on the printing apparatus's capabilities, eliminating manual matching while maintaining accuracy
3Reliability
If the printing apparatus displays attribute information using its stored character code system, then the display can show characters correctly for that code system, but characters input from PC may appear garbled due to code system mismatch
Solution Approach 1:
The print control apparatus dynamically adapts the character code system based on the printing apparatus's capabilities. By automatically requesting and receiving character code system information from the printing apparatus, the system dynamically adjusts the input code system to match the display code system, ensuring compatibility while maintaining display correctness across different code systems

AI summary
A print control apparatus that transmits print data and attribute information regarding the print data to a printing apparatus, which comprises a printing section and a display that displays the attribute information and stores a predetermined character code associated with a character or a symbol displayed on the display, comprises: a code system information request unit that requests the printing apparatus to transmit information of a code system of the stored character code; a code system receiving unit that receives information of the transmitted code system in response to request; an operation input unit to input information; a character code storing unit that stores a predetermined character code associated with a character or a symbol in each code system; and an attribute information input unit that inputs attribute information according to a received code system among code systems associated with the stored character code in response to inputting the attribute information.
