You have to create a plotter as described in the NX documentation for the SDI printer administration.
NX doesn't use the printers installed through the operating system.

What do you mean by "plot file"?
Note "as installed" you could try CGM, as I believe that CGM is a vector based format
Production: NX10.0.3.5 MP5 + patch/TC11.2
