Printer Power Cycle Setting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printers require complex processes to change settings, such as enabling or disabling notification units, which makes quick and appropriate setting changes difficult, especially in environments like restaurant kitchens.
Innovation Solution
A printer configuration that allows settings to be changed by simply turning the power on or off, using a controller to modify settings information stored in the printer's storage based on power supply status, with options including a power switch, plug, or count of power cycles, enabling easy operation of notification units and other settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printer is connected to a host computer and uses a utility or application program to change settings, then the settings can be changed with detailed control options, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent extracts the setting change function from the host computer environment and relocates it directly to the printer. The controller reads the power supply count from storage and automatically determines notification unit settings based on whether the count is odd or even, eliminating the need for host computer connection and utility programs.
Solution Approach 2:
The printer performs setting changes autonomously using its own controller and stored power supply count information. The controller automatically adjusts notification unit settings based on the power supply count without requiring external intervention from a host computer or user interaction with complex software interfaces.
2Productivity
If the printer requires connection to host computer and use of utility programs to change settings, then comprehensive setting options are available, but the setting change process takes too much time
Solution Approach 1:
The printer pre-stores power supply count information in its storage unit, preparing the data needed for setting determination in advance. When power is supplied, the controller immediately reads this pre-stored count and determines settings without requiring time-consuming host computer connections or software operations.
Solution Approach 2:
The patent skips the entire host computer connection process and utility program execution by implementing direct power supply count-based setting determination within the printer. The controller rapidly changes settings by simply reading the stored power supply count and applying the odd/even determination logic, dramatically reducing setting change time.

AI summary
A printer enables easily changing settings. The printer has storage 20c that stores settings information related to the printer 10; and a controller 20 changes, based on the power supply to the printer 10 turning on or off, settings information stored in the storage 20c.
