When scanning data is redirected to a remote desktop or application, you cannot access the scanner on
the local computer. Conversely, when a scanner is in use on the local computer, you cannot access it on
the remote desktop or application.
Tips for Using the Scanner Redirection Feature
n
Click the scanner icon ( ) in the system tray, or notification area, of the remote desktop to select a
non-default scanner or to change configuration settings. On published applications, the system tray
icon is redirected to the local client computer.
You do not have to use the menu that appears when you click this icon. Scanner redirection works
without any further configuration. The icon menu allows you to configure options such as changing
which device to use if more than one device is connected to the local client computer.
Note If the menu that appears does not list any scanners it means that an incompatible scanner is
connected to the client computer. If the scanner icon is not present, it means that the scanner
redirection feature is disabled or not installed on the remote desktop. The scanner icon also does not
appear on client systems that do not support this feature.
n
Click the Preferences option in the menu to select options to control image compression, hide
webcams from the scanner redirection menu, and determine how to select the default scanner.
You can select the option to hide webcams if you plan to use the Real-Time Audio-Video feature to
redirect webcams, which is what VMware recommends. Use scanner redirection with webcams to
take a photograph of yourself and scan it.
Note If a Horizon administrator has configured scanner redirection to use a specific scanner and
that scanner is not available, scanner redirection will not work.
n
Although most TWAIN scanners display the a scanner settings dialog box by default, some do not.
For those that do not display settings options, you can use the Preferences option in the scanner
icon menu, and select Always show Scanner Settings dialog option.
n
Scanning too large an image or scanning at too high a resolution might not work. In this case, you
might see the scanning progress indicator freeze, or the scanner application might exit unexpectedly.
If you minimize the remote desktop, an error message might appear on the local client system,
notifying you that the resolution is set too high. To resolve this issue, reduce the resolution or crop the
image to a smaller size and scan again.
Using the Real-Time Audio-Video Feature for Webcams
and Microphones
With the Real-Time Audio-Video feature, you can use the local client system's webcam or microphone on
a remote desktop. Real-Time Audio-Video is compatible with standard conferencing applications and
browser-based video applications, and supports standard webcams, audio USB devices, and analog
audio input.
