System Requirements for Scanner Redirection

End users can scan information into their remote desktops and applications with scanners that are connected to their local client systems. To use this feature, the remote desktops and client computers must meet certain system requirements.

• Remote desktops

  Remote desktops must have Horizon Agent installed with the Scanner Redirection setup option selected on the parent or template virtual machines or RDS hosts. On Macs, the Horizon Agent Scanner Redirection setup option is deselected by default.

  For information about which guest operating systems are supported for virtual desktops and RDS hosts, and for information about configuring scanner redirection in remote desktops and published applications, see "Configure Scanner Redirection" in the Horizon Remote Desktop Features and GPOs document.

• Horizon Client computer or client access device

  Scanner redirection is supported on macOS Monterey and Big Sur. The scanner device ICA drivers must be installed, and the scanner must be operable, on the client computer. You do not need to install the scanner device drivers on the remote desktop operating system where the agent is installed.
