You could save the file and use Printrun (pronterface) or OctoPrint to print the file.

Is there a small down-arrow next to the “print to file” button? Press the arrow and see if print to USB is an option.

Make sure your printer is set to the correct com port in Machine settings menu.  If the com port is set to AUTO it doesn't work! (Mine needs to be set to COM 7)

Ultimaker Cura versions 2.1 and up don't have a COM port selection in Machine Settings. The (very old by now) Cura 15.04 does have it. The Lulzbot Edition of Cura (Cura LE) also has it.
