Workspace Mode displays both the ThinOS taskbar and the Workspace desktop.
To enable the Workspace Mode option on Admin Policy Tool or Wyse Management Suite, do the following:
1. Go to Configuration Control > ThinOS > Advanced > Broker Settings > Citrix Broker Settings in Admin Policy Tool or
Wyse Management Suite and enable Citrix Workspace Mode.
2. Click Save & Publish.
To enable the Workspace Mode option on Admin Policy Tool or Wyse Management Suite, do the following:
1. On the ThinOS desktop, go to System Setup > Remote Connections and enable Workspace mode.

Citrix printer update limitations
● The ThinOS solution to support the client printer redirection functionality is limited to Type 3 printers only. However, the
solution is subject to changes in the future according to the changes made by Citrix.
● ThinOS supports only PS class when using the Citrix Universal Print Driver policy to automatically create ThinOS client
redirected printers. PCL5 and PCL4 classes are not supported. This is a Citrix limitation.
Citrix printer update
The Citrix printer package on ThinOS is updated to CWA2012 to support all the client printer redirection functionality that is
available in ThinOS v8.6.
Based on the Citrix Host Printer Policy settings, ThinOS 9.1 supports the following:
● Device-Specific Printer Driver support—This method allows Citrix hosts to automatically create client redirected printer
queues based on the peripheral management printer settings of the ThinOS client. The following details are used by the host
print manager to automatically create the printer queues:
○ Name—Printer queue name
○ Printer ID (Printer Identification)—Printer driver name
● Citrix Universal Print Driver support—This method allows Citrix hosts to automatically create printer queues based on the
peripheral management printer settings of the ThinOS client. The following details are used by the host print manager to
automatically create the printer queues:
○ Name—Printer queue name
○ Class—Printer class that is associated by the Citrix host registry to a printer-specific driver name.
NOTE:
ThinOS 8.6 supports the association of PS, PCL5, and PCL4 classes. However, ThinOS 9.1 associations are limited
to the PS class only.
Keyboard Layout Mode
Keyboard Layout Mode enables the user to select the preferred keyboard layout during a Citrix session.
NOTE: To make the Keyboard Layout Mode to take effect, you must sign off broker or reboot the client.
To select the keyboard layout using Keyboard Layout Mode, go to Advanced > Session Settings > Citrix Session Settings >
Keyboard Layout Mode on the Admin Policy Tool or Wyse Management Suite. The following are the available selections from
the drop-down menu:
● Server Default
● Client Setting
● Dynamic Sync
