Universal Scanning

Scanner redirection enables users who are connected to a remote desktop or accessing a published application to make a scan using the scanner that is connected to the client machine. This chapter describes how to configure and use RAS Universal Scanning services.

To configure Universal Scanning, navigate to Site Settings > Universal Scanning.

Universal Scanning uses WIA and TWAIN redirection to let any application using either technology hardware connected to the client device for scanning. With Universal Scanning there is no need to install a specific scanner driver on the server.

Note: The server feature Desktop Experience is required in order to enable both WIA and TWAIN scanning on RD Session Hosts.

By default, the Universal Scanning driver is automatically installed when a host server is added to a RAS Farm and the Agent software is installed on it.

Configuring a scanning rename pattern

By default, Parallels RAS renames scanners using the following pattern: %SCANNERNAME% for %USERNAME% by RAS. For example, if a user named Lois, who has SCANNER1 installed locally, connects to a remote desktop or published application, her scanner is renamed to "SCANNER1 for Lois by RAS".

To change the pattern used to rename scanners, specify a new pattern in the Scanner rename pattern input field. The variables that you can use for renaming are:

  • %SCANNERNAME% — client side scanner name.

  • %USERNAME% — username of the user connected to the server.

  • %SESSIONID% — ID of the active session.

You can configure a different renaming pattern specifically for each server in the list.

Note: Redirected scanners are only accessible by administrator and the user who redirected the scanner.

Adding a scanning application

TWAIN applications that will use the Universal Scanning feature have to be added to the TWAIN configuration. This way they will use the TWAIN driver, hence making it easier for the administrator to set them up.

To add an application to the list of scanning applications:

  1. Select the TWAIN category.

  2. In the right pane, click the plus-sign icon and type the application executable name.

Note: Some applications might use different or multiple executables. Make sure that all required executables are added to the list of scanning applications.

To delete a scanning application from the list, select it in the list and click minus-sign icon.

Note: If you delete an application from the list, the installation of the application will not be affected.
