Network printer

What kind of printer is really a network printer, there is no clear definition in the industry, the more popular argument is that the network printer should be able to print at least on the network, that is to say put this printer on the network connected to the Internet cable installation The corresponding software can be printed without having to connect directly to any computer host. If divided according to this definition, network printers currently have two main methods, one is to use an external print server to achieve network printing, the other is through the built-in print server (commonly known as "network card") To achieve network printing. However, some people think that an external print server can also be used as a network printer because the printer itself is not connected to the network through a network interface. It is still connected to the network through a parallel port. The interface between the parallel port and the network cable is an external device. Print server, not the printer itself. Strictly speaking, when a network prints, only a printer with a built-in print server is a true network printer. In this sense, the network printer is no longer a peripheral device of the PC, but is an independent network node to achieve high-speed printout. Print server: It not only can transmit data, but also organizes and arranges printers and print jobs on the network in a row, using them to work more efficiently.
