So, we are just going to have to ignore this part of your statement. I need to install SMB scanning in an office where there is no network
If they don't mind typing their password at the device they can just use the Address book instead. Do it like this:
Click on the highlighted Details and you can add the username to the share, but passwords can't be done (Address book doesn't encrypt data so the password would be visible to anyone)
Or, if they got it with the printer, scan to personal USB
So that is 3 ways to do it including one that works if the ignored "no network" statement is true (USB)
