Cloud Printer Sharing via Intermediary Code and Server Linking

The patent introduces a sharing code as an intermediary element that bridges the cloud printer and the second terminal. Instead of requiring direct scanning between the printer and terminal, the sharing code acts as a mediator that can be transmitted through various channels (messaging apps, social media, etc.), allowing users to complete binding without physical proximity while maintaining accurate device identification and binding.

The patent extracts the sensitive access key information from the manual input process. Instead of requiring users to manually type access keys, the system generates a sharing code that contains embedded binding information. This separates the security-critical authentication data from the user interaction, allowing flexible sharing while the server securely handles the actual authentication credentials.

The patent performs preliminary actions by pre-generating sharing codes with embedded binding information when the cloud printer is first registered. The server pre-processes the authentication credentials and embeds them in the sharing code, so that when a user receives and scans the code, the binding process is streamlined. This preliminary preparation reduces the complexity of the actual sharing operation, as the heavy authentication logic has already been executed in advance.
