Windows does that behind your back because DOT4_001 is not a real port, 
so it gets treated as a file name in the default-directory. To print on 
such a printer directly, you will have to share it and configure Emacs 
to use the network share name, or I think there is a way to redirect a 
real port (eg LPT1) to such a USB port.
