By using scanner redirection, end users can scan information in their remote desktops and applications with scanning and imaging devices that are connected locally to their client computers.
Scanner redirection supports standard scanning and imaging devices that are compatible with the TWAIN and WIA formats on Windows clients, ICA on Mac clients, and SANE on Linux clients.
After you install Horizon Agent with the Scanner Redirection setup option, the feature works on your remote desktops and applications without further configuration. You do not have to configure scanner-specific drivers on remote desktops or applications.
To ensure the optimal host consolidation, make sure that the Scanner Redirection setup option is only selected for those users who need it. (By default, the Scanner Redirection option is not selected when you install Horizon Agent.) For users who need the Scanner Redirection feature, configure a separate desktop pool and select the setup option only in that pool.
You can configure group policy settings to change default values to adapt to particular scanning and imaging applications or environments. You can also set a policy to deactivate or activate the feature altogether. With an ADMX template file, you can install scanner redirection group policy settings on your Active Directory server or on individual desktops. See Configuring Scanner Redirection Group Policy Settings.
When scanning data is redirected to a remote desktop or application, you cannot access the scanning or imaging device on the local computer. Conversely, when a device is in use on the local computer, you cannot access it on the remote desktop or application.
