This is simply not possible right now, because we have no way of
retrieving or saving the authentication information in the backend
other than via a hardcoded username and password in the URI.

That is why we do not recommend using SMB for printing *to* Windows,
and why all of the documentation says not to do it.

You can use TCP/IP printing services (aka LPD) and IPP (via IIS and
a /printers virtual directory) to print from CUPS to a Windows print
server without requiring authentication; both methods will get the
(unauthenticated) username from the CUPS system...
