First of all, we need to know that the printer can connect to different ports of the computer, such as USB interface, Ethernet interface, parallel port, wireless network and so on. And the setting method of each port is slightly different.
1.USB interface
If the printer is connected to the computer through a USB interface, you can set the selected port of the printer by the following steps:
A. Open the "Devices and Printers" (or "Printers and Scanners") option of the computer.
B locate the icon of the printer, right-click the printer and select "printer properties".
C. In the pop-up dialog box, click the "Port" tab, find the USB interface for connecting the printer, such as "USB00 1", and then click "Apply" or "OK" to save the settings.
2. Ethernet port
If the printer is connected to the computer through an Ethernet port, you can set the selected port of the printer by the following steps:
A. Open the "Devices and Printers" (or "Printers and Scanners") option of the computer.
B locate the icon of the printer, right-click the printer and select "printer properties".
C. In the pop-up dialog box, click the "Port" tab to find the Ethernet port connected to the printer, such as "IP _192.168.100", and then click "Apply" or "OK" to save the settings.
3. Parallel port
If the printer is connected to the computer through a parallel port, you can set the selected port of the printer by the following steps:
A. Open the "Devices and Printers" (or "Printers and Scanners") option of the computer.
B locate the icon of the printer, right-click the printer and select "printer properties".
C. In the pop-up dialog box, click the "Port" tab to find the parallel port connected to the printer, such as "LPT 1", and then click "Apply" or "OK" to save the settings.
4. Wireless network
If the printer is connected to the computer through a wireless network, you can set the selected port of the printer by the following steps:
A. Open the "Devices and Printers" (or "Printers and Scanners") option of the computer.
B locate the icon of the printer, right-click the printer and select "printer properties".
C. In the pop-up dialog box, click the "Port" tab to find the wireless network port to which the printer is connected, such as "IP _192.168.100", and then click "Apply" or "OK" to save the settings.
In addition, some high-end printers may need more complicated setup procedures, including access control, IP address, gateway, subnet mask, etc. At this time, we can get more detailed instructions by looking at the user manual of the printer or official website.
In a word, no matter what port the printer connects, the settings it chooses are very important. Only by selecting and setting the port correctly can the printer work normally and improve the work efficiency. Therefore, you need to be careful when setting the printer port, and set it according to the above steps.
