All About The Windows Event Manager and scanner events in
Windows 98, Windows Me, Windows 2000 and Windows XP.
Windows Platforms provide a mechanism for software to handle external events for
a scanner device like the SHARP AL-1642CS products. This mechanism is
controlled by the device manager on a device basis. Applications that can handle
events from a scanner/camera device register with the Windows Event Manager and
shown as available in the registered applications. The path an event takes to get to
the user's selected application depends upon the event settings for the device.
