Printing from a Computer Causes an Error (Network Environment)

If you change the IP address of the machine or add a printer, an error might occur and printing may not be possible.
This problem occurs when there is a problem with the print port setting. Log in to the computer as an administrator and configure the settings.

This port can automatically detect the IP address of the machine. Even if you change the IP address of the machine, the connection is maintained if the machine and the computer are on the same subnet. Therefore, you do not need to add a new port each time you change the IP address. Usually, select this option.
To add a standard TCP/IP port,
This is a built-in port for Windows. If you change the IP address of the machine, you need to add a new port each time. Select this option if you are using the machine in a IPv6 environment or if you cannot add an MFNP port.

Change the port type and number.
If you change the print protocol (LPD or RAW) settings or the port number on the machine, also change the settings on the computer to the same settings. This operation is not required for the WSD port.
