QR Code Address Conversion for Mobile Printer Job Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming systems require manual input of printer network addresses from mobile terminals, which is cumbersome and prone to errors, and do not provide a straightforward method for instructing printers to execute jobs.
Innovation Solution
An image forming system that uses a two-dimensional code output unit to convert address information into a QR code, which is photographed by a mobile terminal, inversely converted back into address information, and used to access and transmit job instructions to the image forming apparatus, eliminating the need for manual address input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of network address is used, then connection to image forming apparatus can be established, but operation complexity increases and error rate increases
Solution Approach 1:
A two-dimensional code (QR code) is introduced as an intermediary carrier that contains the network address information. The mobile terminal photographs this code to automatically obtain the address, eliminating manual input while ensuring accurate transmission of connection information.
Solution Approach 2:
The manual mechanical input process (typing address characters) is replaced by an optical system (photographing the two-dimensional code with camera). This substitution eliminates typing errors and simplifies the operation to a single photographing action.
2Ease of operation
If two-dimensional code system is implemented, then ease of operation improves, but system complexity increases
Solution Approach 1:
The two-dimensional code serves multiple functions: it contains network address information, enables automatic connection establishment, and triggers job transmission. This multi-functionality consolidates several operations into a single code structure, managing complexity through functional integration.
Solution Approach 2:
The mobile terminal automatically performs address extraction, connection establishment, and job transmission after photographing the two-dimensional code. The system serves itself by automatically processing the information contained in the code without requiring user intervention for each step.

AI summary
An image forming system includes an image forming apparatus and a mobile terminal. The image forming apparatus includes: a two-dimensional code output unit for outputting a two-dimensional code into which address information of the image forming apparatus is converted; and a job execution unit for executing a job transmitted from the mobile terminal that has accessed the image forming apparatus based on address information into which the two-dimensional code obtained by photographing an image of the two-dimensional code outputted from the image forming apparatus by the mobile terminal is inversely converted. The mobile terminal includes: a photographing unit for photographing an image of the two-dimensional code; an inverse converter for inversely converting the photographed two-dimensional code into address information; and a communication unit for accessing an address of the image forming apparatus, which address is obtained through the inverse conversion, to transmit a job.
