Printer Cutter Control for Continuous Paper Cutting Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers lack the ability to automatically adjust cutting methods according to the specific requirements of the host apparatus, often resulting in inconvenient default cutting methods when receiving printing data, especially during automatic feed and cutting operations without explicit commands.
Innovation Solution
The printer includes a command receiving module, a first cutting control module, and a recording module to switch between full and partial cutting methods based on instructions from the host device, and a second cutting control module to cut the paper according to the stored method without continuous commands, ensuring alignment and tidy cutting of the continuous paper.

Engineering Contradiction Analysis
1Extent of automation
If the printer uses a default cutting method preset before shipment, then the printer can automatically cut the continuous paper without receiving commands from the host apparatus, but the cutting method may not match the host apparatus's operational requirements, reducing convenience
Solution Approach 1:
The printer dynamically switches between different cutting methods (full cutting, partial cutting, no cutting) based on the operation mode. When operating in normal printing mode, it follows host apparatus commands. When operating in automatic feed mode without commands, it automatically selects the appropriate cutting method, making the system adaptive rather than static.
Solution Approach 2:
The printer serves itself by automatically determining and executing the appropriate cutting method when no command is received from the host apparatus. The control unit detects the operation mode and autonomously decides whether to perform full cutting, partial cutting, or no cutting, eliminating the need for continuous external commands.
2Manufacturing precision
If the printer receives cutting method commands together with printing data, then the cutting method can be precisely controlled according to host apparatus requirements, but the printer cannot automatically adjust cutting methods during automatic feed operations without commands
Solution Approach 1:
The control unit performs multiple functions: it receives and executes cutting method commands from the host apparatus when printing data is provided, and simultaneously autonomously determines cutting methods when operating in automatic feed mode without commands. This multi-functionality allows the printer to adapt to different operational scenarios.
Solution Approach 2:
The printer preliminarily determines the cutting method based on the detected operation mode before actually performing the cutting operation. This preliminary determination allows the printer to be prepared and ready to execute the appropriate cutting method whether a command is received or not.
3Manufacturing precision
If the printer always performs full cutting, then the continuous paper is completely separated for clear receipt ends, but the time required for cutting increases and may not be suitable for all operational scenarios
Solution Approach 1:
The cutting operation is localized to only what is necessary for the specific operational scenario. Instead of always performing complete full cutting, the printer applies partial cutting (cutting only at specific positions like leading end or trailing end) when appropriate, and no cutting when the receipt should remain attached, optimizing both quality and efficiency.

AI summary
A printer comprises a cutter; a non-volatile storage module; a command receiving module configured to receive a command for instructing a cutting method of a continuous paper from an information processing apparatus connected to the printer; a first cutting control module configured to control an operation of the cutter to cut the continuous paper in the cutting method instructed by the command; a recording module configured to record information indicating the cutting method in the storage module at the time of paper cutting based on the command; and a second cutting control module configured to cut the continuous paper in a cutting method indicated by the information stored in the storage module at the time of paper cutting without the command.
