stm32F0 discovery and printf on usart

Hi all. I'm net to STM micros , so excuse the stupid question.

I've set up USART1 on the stm32F0 discovery board, using the SPL , NOT cube.

If I send data out the usart using the "USART_SendData" function provided by the peripheral library , the data

is sent out no problem , but if I use printf("dsfs") , nothing is sent.

How do I ensure the printf sends data to the serial port , and not a screen or anywhere else?

I am using Atollic6
