I’m not aware of any such trick on MacOS. But, as you are printing to a Windows based system, I think you use a unique backend for all those printers.
If so, I’d suppose to write a wrapper script for your backend which in turn calls the original backend but exchanges the username 
(the second command line option, I think).
