What port does Windows use for printing?

It depends on how you print using your Windows computer. For example, if you have installed an offline printer, there is nothing called a port for that purpose. However, if it is a network printer, it may use TCP or RPC. For your information, TCP uses 139 (SMB) port for Windows SMB printing works.

What ports are required to print?

Different printers use different ports to communicate with the host computer and client computers. In most cases, you can find them using 2501, 9101, 9600, etc. However, it is not definite that your printer uses the same ports. As the most recent Windows 11 update has opted for RPC, these ports might be different if you use Windows 10.
