After selecting the port, you need to set the port accordingly. The specific setting method can be carried out according to the instructions of the printer.

The setting of network ports requires network configuration, including IP address, subnet mask, gateway and other parameters.

If the printer uses LPT port, you need to check whether there is any hardware conflict before setting.
