TWAIN devices

Requirements

• The scanner must be TWAIN compliant.
• Install the TWAIN drivers on the local device. They are not required on the server.
• Attach the scanner locally (for example, through USB).
• Ensure that the scanner is using the local TWAIN driver and not the Windows Image Acquisition service.
• Ensure that there is no policy applied to the user account that is used for the test, and which is limiting the bandwidth within the ICA session. For example, client USB redirection bandwidth limit.
