Printer is one of the most important devices in our daily office or home use, but in use, it is very likely that it will not work normally or the printing speed will be slow. One way to solve these problems is to change the port settings of the printer. This article will introduce how to change the port settings of the printer, as follows:

1. First, we need to find the device manager of the printer. On Windows systems, you can open the Device Manager by pressing the Win+X key and then selecting the Device Manager option.

2. In Device Manager, we can see the name of the printer, which is listed in "Printer" or "Other Devices". Right-click the printer name and select Properties.

3. In the Printer Properties dialog box, select the Ports tab. Here, we can see the current port settings of the printer.

4. Click the "Change Port Settings" button to pop up the "Port Settings" dialog box. In this dialog box, you can choose the print port used by the printer, and you can also add or delete ports.

5. If you want to add a new port, you can select the "Add Port" button. Then, select a new port type, such as network port or local port.

6. If you want to delete an existing port, you can select the port to be deleted, and then select the "Delete Port" button.

7. In the process of changing the printer port, you need to ensure that you have administrator rights, otherwise you may encounter an error with limited rights.

8. After changing the port, you need to restart the printer and computer for the change to take effect.

In a word, changing the port settings of the printer is a relatively simple process, which can help you solve many printer-related problems if used correctly. Be sure to back up important data and make sure that you have administrator rights.
