The operating pressure is usually set by the temperature of the condenser.  The cooling medium will set that, and the bubble point of the overhead liquid product (or reflux) at that temperature will set the pressure.

 

The column operating temperature is set primarily by the reboiler temperature required at that pressure to boil the bottoms product.
