[Cura 4.3 How to send to the printer.]

I was using Cura version 14 for my Prusa I3

 

Just got a new computer and upgraded to 4.3.

 

I can load my stl file, slice it and output a gcode file.   But...

 

I see no way to send it to the printer!  How do I do that?  Printer is connected via USB was called COM3 on the old computer.
