Cloud PIN Printing Workflow to Prevent Unnecessary Job Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cloud printing systems with PIN printing, if a user forgets the PIN code, the print job is transmitted to the printing apparatus, leading to wasted traffic and communication fees due to unsuccessful PIN verification.
Innovation Solution
The printing apparatus checks the job attributes for a PIN attribute before fetching the print job, and only if it matches, it requests the PIN code from the user and verifies it with the cloud printing service, thereby reducing unnecessary data transfer.

Engineering Contradiction Analysis
1Productivity
If the print job is transmitted to the printing apparatus before PIN verification, then the printing process can proceed smoothly, but wasted traffic and communication fees occur when PIN verification fails
Solution Approach 1:
The printing apparatus performs PIN verification before transmitting the print job data. The authentication unit verifies the PIN code against the print job information received from the cloud printing service, and only transmits the print job if verification succeeds. This preliminary verification action prevents wasted communication traffic when PIN verification would fail.
Solution Approach 2:
The system applies preliminary anti-action by verifying the PIN code before allowing the print job transmission to proceed. If the PIN verification fails, the system actively prevents the transmission of print job data, thereby counteracting the potential waste of communication resources before it occurs.
2Ease of operation
If the PIN verification is performed after print job transmission, then the printing apparatus can receive the job data, but unnecessary data transfer occurs when verification fails
Solution Approach 1:
The authentication unit verifies the PIN code against the print job information before the print job data is transmitted to the printing apparatus. This preliminary verification ensures that only authenticated print jobs receive data transmission, preventing unnecessary data transfer when PIN verification would fail.
3Adaptability or versatility
If the print job is transmitted without checking PIN attribute, then the system maintains compatibility with non-PIN printing, but traffic is wasted when PIN verification is required but not checked
Solution Approach 1:
The printing apparatus checks the job attributes to determine whether a PIN attribute is present. This local quality check allows the system to adapt its behavior based on the specific print job requirements - performing PIN verification only when necessary while maintaining compatibility with non-PIN printing jobs, thereby avoiding unnecessary communication traffic.
Solution Approach 2:
The system dynamically adjusts its operation based on the presence of PIN attributes in job information. The authentication unit checks job attributes and conditionally performs PIN verification and data transmission only when PIN attributes are detected, making the system flexible and adaptive to different printing scenarios.

AI summary
An information processing apparatus is provided. The apparatus transmits, to a printing apparatus, attribute information regarding a designated print job, out of at least one print job registered together with attribute information, in response to a request, from the printing apparatus, for the attribute information regarding the designated print job, receives a job fetch request from the printing apparatus together with password information input to the printing apparatus in accordance with a password attribute included in the attribute information, verifies the received password information with a value of the password attribute included in the attribute information regarding the designated print job, and transmits the designated print job and the attribute information regarding the designated print job to the printing apparatus if the verification is successful.
