Description:

CA DLP includes functionality to control print functionality including Print Screen. In order for DLP print functionality to work in a Citrix Presentation Server version 10 environment, a registry fix is needed to keep the ALT+PRINTSCREEN keyboard shortcut available on the local desktop.

Solution:

IMPORTANT: This article contains information about modifying the registry.
Before you modify the registry, make sure to create a back up of the registry and ensure that you understand how to restore the registry if a problem may occur.
For more information about how to back up, restore, and edit the registry, please review the relevant Microsoft Knowledge Base articles on support.microsoft.com

On the Citrix client system, change the value of the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA
Client\Engine\Configuration\Advanced\Modules\WFClient
Value Name: ICAPrntScrnKey
Type: REG_SZ
Value: <value>

For example: Value: F12

Where the Print Screen function in the ICA session has been assigned to the F12 key.
