USB print server is the best method for sharing your local USB over the network or accessing USB remotely from a network computer. In this article we went over the most popular methods of sharing a device over Ethernet.
USB print server allows you to avoid using computers when installing the network printing service. You just insert your printer into a print server and connect the print server to your network router with an Ethernet cable. In some cases you may also need to install some additional software. 
One of the best things about an Ethernet USB print server is that it’s completely independent of any network PC, and, in fact, works as a small computer itself. This ability helps to not overload the user’s work environment.
One more thing you should keep in mind selecting a hardware print server is the maximum number of USB or serial devices it supports. A standard hardware print server is able to share from 1 to 4 serial devices at a time, so if you need to provide remote access to more devices simultaneously, it’s better to consider the software method.
As it doesn’t seem possible to share an unlimited number of USB or serial peripherals with a hardware print server, you may try the software method to achieve this.
One of the key advantages of the program is that it lets you share not only printers but USB or serial devices of any other type, including keyboards, hard drives, cameras, etc. What is more, with the software you get the ability to choose the number of devices that will be shared.
Another good software option that can function as a USB print server is USB Network Gate. 
An ability to share USB port devices via LAN only is its greatest advantage over FlexiHub, which requires Internet access all the time. What is more, USB Network Gate allows redirecting USB devices to virtual machines and blade servers. Sharing USB devices over RDP protocol is USB Network Gate's another main feature, which makes it easy to access local devices while working in the RDP session.
Here are some benefits FlexiHub and USB network Gate offers:
Cons:
The USB 10/100 Mbps print server is a great solution for sharing a USB printer on office LANs or home networks. It’s a small piece of equipment that fits in the palm of your hand but offers big benefits. Using this device saves the hassle and expense of providing a printer for each user.
Besides being small and lightweight, this print server is easily installed using remote access and its intuitive wizards. Your printer does not need to be directly connected to your workstation. The printer can be located anywhere on your network and can be monitored and managed through a web browser interface.
You only need two cables to complete the installation of the print server. Connect the device to your printer via a USB cable attached to the printer’s USB port. An RJ45 cable is used to connect the server to the network, making it accessible to remote network-connected users.
