It is in this unit to a USB Device Server, so no print server. The device allows a system with a USB drive to connect, which is not in the immediate vicinity of the USB device or no physical USB connection has. For example, virtual systems. Via software emulates USB ports on the system and is connected via the IP network with the USB Device Server, as they really put on the system. So, for example, the USB printer then connected directly to the system and not as irrefuehrender way with a USB print server. This is an entirely different principle. The USB Device Server gets from me 5stars since been in multiple systems, mainly virtualized systems 24/7 in server segment, error-free in use.
