novice attempting to assign address to interface

Hello everyone.

I have a network-capable printer, but the ability to configure the IP ​address on the printer has stopped working. In an attempt to extend the lifetime of the printer I purchased a RB750r2 with the thought of assigning an IP address to an interface and plugging the printer into that interface. However, I find the language and explanations in the MikroTik RouterOS documentation to be quite ambiguous and incomplete, especially for a novice.

I would be very grateful if someone could point me in the correct direction in order to achieve the above described task, preferably in terms of the WinBox GUI. Thanks very much.

It would probably help to share some more info. What address is the printer stuck with, the new address that it should have, things like that…
