Do not display the TWAIN device user interface when acquiring images.  This argument is only valid for TWAIN drivers that allow the user interface to be turned off when acquiring images.


Please note:
Some devices that have document feeders can acquire without a user interface, however may not work correctly if the device detects that no paper is in the document feeder at the start of the acquisition.  For these devices, the -nouiwait option may work successfully instead of -noui.


Default Setting:

Show the user interface of the device when acquiring images.
