Cloud Print Reference Job URI Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud print services face issues with capacity limits, where print jobs exceeding file size limits are not transmitted, leading to incomplete printing and increased data transfer costs due to excessive data transfer.
Innovation Solution
An information processing apparatus that transmits a reference print job, formatted with a designated storage location in URI format, instead of the original print job, allowing the image forming apparatus to obtain data directly from the cloud storage, thus avoiding capacity limits and reducing data transfer costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the original print job with large document data is transmitted to the cloud print service, then the printing can be performed with complete data, but the data transfer cost increases and the capacity limit is exceeded
Solution Approach 1:
The patent extracts only the necessary reference information (URI pointing to document data) from the original print job and transmits this minimized reference print job to the cloud print service. The actual document data is obtained directly from the cloud storage service by the image forming apparatus, eliminating the need to transfer the entire large document data through the cloud print service, thus reducing data transfer costs while ensuring printing completion.
2Reliability
If the capacity limit for print jobs is enforced by the cloud print service, then the load is reduced and service stability is improved, but print jobs exceeding the limit are refused and printing cannot be executed
Solution Approach 1:
The patent introduces a cloud storage service as an intermediary between the client terminal and the image forming apparatus. The client terminal stores document data in the cloud storage service and transmits only a reference print job containing the URI to the cloud print service. The image forming apparatus then directly obtains the document data from the cloud storage service, allowing large files to be handled without exceeding cloud print service capacity limits while maintaining service stability.
3Productivity
If the cloud print service receives and stores the complete document data in the print job, then the printing can be performed, but the data transfer cost increases
Solution Approach 1:
The patent extracts only the essential reference information (URI) from the complete document data and transmits this minimized reference print job to the cloud print service. The actual document data is obtained directly from the cloud storage service by the image forming apparatus, eliminating the need to transfer the entire large document data through the cloud print service, thus reducing data transfer costs while ensuring printing execution.

AI summary
It is possible to suppress a data transfer cost in printing using a cloud print service. A client terminal 102 transmits a print job for printing data to an image forming apparatus 101 via a cloud print service 107. In a case that the image forming apparatus 101 has a capability to process a reference print job that has designated a storage location of the data in a URI format, the client terminal 102 transmits the reference print job to the cloud print service 107.
