How to add a wired printer to a wireless printer

Ordinary printers have USB interfaces. In order to realize wireless printing, the printer needs to be connected to the network. At this time, a "print server" is needed, which will be introduced in detail below.

1, print server

Through the print server, you can enjoy the printer and realize the wireless printing function. The size of a print server is similar to that of a home network set-top box, and it has a USB interface and a network port, wherein the USB interface is connected to the USB interface of a common printer, and the network port is connected to a switch (wireless router of the home network) in the local area network, as shown in the following figure.

Step 2 do it yourself DIY

Materials prepared: openwrt router or industrial computer, ordinary printer. I use an idle industrial computer J 1900 here.

Firmware preparation: you can download the corresponding firmware from koolshare forum. I use lede firmware.

Transformation steps

1) Write lede firmware into the industrial computer or router, and the specific process will not be described in detail. There are related tutorials online.

2) Connect the printer to the USB interface of the industrial computer through a USB cable;

3) Log in to the background of the industrial computer, click Service Printing Service in turn, and automatically detect the printer, as shown in the following figure;

4) After identifying the printer, make relevant settings and select the LAN interface and port corresponding to the printer (default is 9100);

5) When computers and other terminals use "modified" printers, they need to install relevant drivers, and then add printers by "adding printers using TCP/IP addresses or hosts";

6) When adding a network printer to the computer, you need to enter the IP address and port number of the printer, as shown in the figure below;

The above is the method of transforming ordinary printers into network printers. If there is a wireless router in the network, you can support wireless printing. The easiest way is to buy a print server on a treasure, of course, using an industrial computer or a DIY router that supports brushing.
