User Operation of Scanner Redirection
With scanner redirection, users can operate physical scanners and imaging devices that are connected to
their client computers as virtual devices that perform scanning operations in their remote desktops and
applications.
Users can operate their virtual scanners in a way that closely parallels the way that they use the scanners on
their locally connected client computers.
n
After the Scanner Redirection option is installed with View Agent, a scanner tool tray icon icon ( ) is
added to the desktop. On RDS applications, the tool tray icon is redirected to the local client computer.
You do not have to use the scanner tool tray icon. Scanning redirection works without any further
configuration. You can use the icon to configure options such as changing which device to use if more
than one device is connected to the client computer.
n
When you click the scanner icon, the Scanner Redirection for VMware Horizon menu is displayed. No
scanners appear in the menu list if incompatible scanners are connected to the client computer.
n
By default, scanning devices are autoselected. TWAIN and WIA scanners are selected separately. You
can have one TWAIN scanner and one WIA scanner selected at the same time.
n
If more than one locally connected scanner is configured, you can select a different scanner than the one
that is selected by default.
n
WIA scanners are displayed in the remote desktop's Device Manager menu, under Imaging devices.
The WIA scanner is named VMware Virtual WIA Scanner.
n
In the Scanner Redirection for VMware Horizon menu, you can click the Preferences option and select
options such as hiding webcams from the scanner redirection menu and determining how to select the
default scanner.
You can also control these features by configuring scanner redirection group policy settings in Active
Directory. See “Scanner Redirection Group Policy Settings,” on page 167.
