Scanning on non-windows client platforms - SANE Redirection
Introduction
Users can scan documents from TWAIN applications inside their Citrix sessions from ChromeOS endpoints. When a user tries to scan a document from an application, the Citrix scanning module redirects the request to the client endpoint to achieve scanning from the scanner and the files are sent to the VDA once the scan is complete.

- Citrix DaaS
Session Host
- Operating system
- Windows 10 1809 or later
