An elegant trick is actually used there: A network share is set up on a computer within the network, on which the scans can then be stored. Meanwhile there are a lot of multifunctional devices on the market, consisting of printer, fax and scanner including network connection. The software Vuescan, occasionally suggested, uses this interface according to my information. If there is no updated WIA driver, you can only try to scan via the TWAIN interface.

Scanning via this interface is not possible without a WIA driver adapted to the currently used Windows version. I had explained this in more detail in my German blog post Scanner unter Windows 7. This was first noticed on a wider front with Windows Vista, later with Windows 7 and subsequent versions.

As a result, all older WIA drivers no longer work under newer Windows versions. Starting with Windows Server 2003, Microsoft switched the model of the WIA service from Local System to Local Service. Microsoft has introduced the WIA 1.0 standard for Windows Millennium and also supported it under Windows XP. Unfortunately, there is a large hurdle for older scanners.
In order to run the scanner under Windows, a WIA driver of the scanner manufacturer suitable for this operating system must be installed. Windows Fax and Scan as well as other functions of the operating system or application programs can use WIA to initiate a scan. This is the interface introduced by Microsoft from Windows Millennium ( WIA stands for Windows Image Acquisition). Here you can only try to uninstall the manufacturer's Twain driver and reinstall a new driver or the old driver. If this does not work, the device's TWAIN driver may no longer be compatible with the existing Windows version. can be used to address the scanner directly and to continue using the image data of the scan. Then application programs such as PhotoFiltre etc. This must be supplied with the device in a version compatible with the Windows version or may be downloaded and installed at a later date from the manufacturer's website. The data source is formed by the scanner or digital camera driver. TWAIN 2.4, released December 15, 2015, consists of three elements: The data source, the application program and the source manager. TWAIN is is a standard established in 1992 by Aldus Corporation, Eastman-Kodak, Hewlett-Packard and Logitech for exchanging data between image input devices (scanners, digital cameras, etc.) and applications for Microsoft Windows and Apple Macintosh. With modern scanners connected to a computer via USB, the scanner is controlled from applications using two standards: Twain and WIA.
Within the text below I will try to explain the various approaches to control scanners and point out the associated problems.
