TSScan

TSScan is a remote terminal service utility designed to help you scan documents and save them as images or PDF, but without having to bother with installing the scanner drivers on your main machine.

Simply put, the program can act as a virtual scanner for your terminal server. As a result, the tool first needs to map all locally available scanners that are stored in the virtual DS of the host. Consequentially, after you are done with the scan, you can easily transfer the images to the desired applications, by selecting the one listed within the GUI.

In case you are concerned about security, then you will be happy to learn that all the communication is done locally using the dynamic redirection of TWAIN technology. As a side note, you should make sure that the scanners support TWAIN protocol, mainly since not all manufacturers strictly follow it.

You should bear in mind that you need to activate these settings and the only way to get the adequate configuration window is after you install the server app via an account with Administrator privileges. Accessing the app as Administrator allows you to transfer RAW images, compress images that are being scanned and enable the support for bundled memory transfer. The later entails that each picture can be sent to the host as a package combining the image transfer as a whole, rather than a separate piece.
