Cloud Printing File Transmission via Embedded App
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud printing technologies require users to download files to their terminal devices before uploading them to cloud printing servers, which complicates the printing process and increases the risk of file leakage.
Innovation Solution
A method and apparatus that allow users to initiate printing directly from a first application by transmitting the target file to a cloud printing server through a preset printing application, eliminating the need for local file storage and reducing security risks by encrypting files and using specific identifiers for acquisition requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users download files to terminal devices before uploading to cloud printing servers, then the printing process can be completed, but the process becomes complicated and the risk of file leakage increases
Solution Approach 1:
The patent extracts the file storage function from the terminal device and places it directly on the cloud printing server. Users can directly select and print files from the cloud without downloading them to their terminals, thereby simplifying the printing process and reducing the risk of file leakage during local storage and transfer.
Solution Approach 2:
The patent introduces an intermediary mechanism where the cloud printing server acts as a direct bridge between the user's terminal and the printing device. The server receives printing requests, manages file storage securely in the cloud, and coordinates the printing process, eliminating the need for files to be stored locally on terminal devices.
2Ease of operation
If files are stored locally on terminal devices, then printing can be performed, but the risk of file leakage increases
Solution Approach 1:
The patent removes the file storage step from the terminal device and relocates it to the cloud printing server. Users can directly access and print files from the cloud without them being stored locally, thereby maintaining ease of operation while eliminating the security vulnerability of local file storage.
Solution Approach 2:
The patent implements preliminary actions by pre-uploading files to the cloud printing server before the printing process begins. This allows files to be securely stored and managed in the cloud in advance, so that when users want to print, they can directly select from already-stored files without needing to transfer or store them locally at the moment of printing.
3Reliability
If cloud printing server stores all files, then security is improved, but server storage requirements increase
Solution Approach 1:
The patent applies local quality by storing only the specific files that are needed for printing on the cloud printing server, rather than storing all user files. Files are stored in the cloud on a per-printing-request basis, allowing the server to maintain high security for printed files while optimizing storage resource utilization.
Data Source
AI summary
Provided are a printing method and apparatus, and an electronic device. The method includes: receiving, in an interface where a first application runs, a printing request initiated by a user for a target file displayed in the interface; running, according to the printing request and in the interface where the first application runs, a preset printing application embedded in the first application; and transmitting the target file to a cloud printing server by using the preset printing application, and instructing the cloud printing server to send the target file to a printing device upon receiving an acquisition request from the printing device, to cause the printing device to print the target file.
