Method to realize scanner redirection between a client and an agent

A non-transitory computer-readable medium comprising instructions that are executable in a remote desktop system that includes a client computing device that has running therein a scanner redirection module, and a host server, the scanner redirection module including a data source manager for communicating with a data source that is configured to communicate with a physical scanner, wherein the instructions when executed cause the client computing device to carry out a scanner redirection method comprising:

• in response to receiving from an application running on the host server, a request for scanner properties:
• acquiring from the data source, properties of the physical scanner that the data source acquired from the physical scanner, and then transmitting the properties of the physical scanner to the application;
• after transmitting the properties of the physical scanner to the application, in response to receiving from the application, a request to adjust one of the properties of the physical scanner:
• transmitting to the data source, a request to adjust the property of the physical scanner, in response to which the data source requests the physical scanner to adjust the property of the physical scanner;
• after transmitting the request to adjust the property of the physical scanner to the data source, in response to receiving from the application, a request for a scanned image:
• transmitting to the data source, a request to acquire the scanned image from the physical scanner, in response to which the data source acquires the scanned image from the physical scanner having the adjusted property;
• and
• upon receiving the scanned image from the data source, transmitting the scanned image to the application.

A client computing device of a remote desktop system, the client computing device having running therein a scanner redirection module, the scanner redirection module including a data source manager for communicating with a data source that is configured to communicate with a physical scanner, and the client computing device including a processor configured to execute instructions from memory to:

• in response to receiving from an application running on a host server of the remote desktop system, a request for scanner properties:
• acquire from the data source, properties of the physical scanner that the data source acquired from the physical scanner, and then transmit the properties of the physical scanner to the application;
• after transmitting the properties of the physical scanner to the application, in response to receiving from the application, a request to adjust one of the properties of the physical scanner:
• transmit to the data source, a request to adjust the property of the physical scanner, in response to which the data source requests the physical scanner to adjust the property of the physical scanner;
• after transmitting the request to adjust the property of the physical scanner to the data source, in response to receiving from the application, a request for a scanned image:
• transmit to the data source, a request to acquire the scanned image from the physical scanner, in response to which the data source acquires the scanned image from the physical scanner having the adjusted property;
• and
• upon receiving the scanned image from the data source, transmit the scanned image to the application.
