XenApp lets users control client-attached TWAIN imaging devices, such as scanners and cameras, from published applications. This feature is known as TWAIN redirection because XenApp provides TWAIN support by redirecting commands sent from a published application on the server to the client device.
Users can connect regardless of connection type. However, XenApp requires the following for TWAIN support:
- The imaging device must be connected locally to the user device and have the associated vendor-supplied TWAIN driver installed locally.
- Citrix online plug-in 11.x or later or the Citrix offline plug-in.
- XenApp 32-bit and 64-bit servers support TWAIN redirection for 32-bit TWAIN applications only. XenApp does not support 16-bit TWAIN drivers.
- The Client TWAIN device redirection policy setting must be added to the appropriate policy. To configure image compression, add the TWAIN compression level setting and select the appropriate compression level.
The following table lists the TWAIN hardware and software tested with XenApp. While other TWAIN devices may work, only those listed are supported.
