Username needs to be exactly how it is shown on yours in the brackets here
The port should be 445 not 139
The firmware also needs to be the latest, which is the one here to have any realistic hope of scanning to Windows 10, but even then, it only supports SMBv1, and MS/Apple and everyone else has effectively disabled the use of SMBv1. (Yes, I see you manually enabled it, but MS will now disable it on the next update, and many routers will actively stop it too)
Your best bet by far is to add the share as FTP, then everyone can use it how they are currently, and the printer can do it via FTP.
