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.

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.
n
When you operate a TWAIN scanner, the TWAIN Scanner Redirection for VMware Horizon menu
provides additional options for selecting regions of an image, scanning in color, black and white, or
grayscale, and choosing other common functions.
n
To display the TWAIN user interface window for TWAIN scanning software that does not display the
window by default, you can select an Always show Scanner Settings dialog option in the VMware
Horizon Scanner Redirection Preferences dialog box.
Note that most TWAIN scanning software displays the TWAIN user interface window by default. For
this software, the window is always displayed, whether you select or deselect the Always show
Scanner Settings dialog option.
Note If you run two RDS applications that are hosted on different farms, two scanner redirection tool tray
icons appear on the client computer. Typically, only one scanner is connected to a client computer. In this
case, both icons operate the same device, and it does not matter which icon you select. In some
situations, you might have two locally connected scanners and run two RDS applications that run on
different farms. In that case, you must open each icon to see which scanner redirection menu controls
which RDS application.
For end-user instructions for operating redirected scanners, see the Using VMware Horizon Client for
Windows document.
Configuring Scanner Redirection Group Policy Settings
You can configure group policy settings that control the behavior of scanner redirection on your Horizon 7
desktops and applications. With these policy settings, you can control centrally, from Active Directory, the
options that are available in the VMware Horizon Scanner Redirection Preferences dialog box on users'
desktops and applications.
You do not have to configure these policy settings. Scanner redirection works with the default settings that
are configured for scanning devices on remote desktops and client systems.
