PS34-PoE offers one Centronics and one USB 2.0 port each; the USB interface supporting all currently existing USB standards: USB 1.1, USB 2.0 Full-Speed (12Mbit/s) as well as the fastest USB standard, USB 2.0 Hi-Speed (480Mbit/s). Plus, the print server's USB port may be extended using a standard hub to support up to four printers. PS34-PoE, therefore, homogenises the network infrastructure to a great extent, and reduces the number of required network adapters; lowering follow-up costs from operation and maintenance.
