That tells us nothing!

You've been directed to the Posting Tips before:

You need to give full details before anyone is going to be able to help you!

So, again:

1. What, exactly, have you tried?
   Show code (following the instructions above) & give full hardware details, tools used, etc.
2. What were you expecting to happen?
3. What actually happened - give full details; not just, "it didn't work"
4. What investigation/testing/debugging have you done to find out what's going wrong?

Some general debugging tips here:

Hello, I'm finding the article very interesting and it seems to be the answer to my question about how to direct the printf output to the virtual connection port on the USB, but I couldn't help but ask if the process is exactly the same for the Nucleo-F411RE board.

Is the UART used the same? And how many pins are also the same? I think the rest is the same.

In response to my anxious question, it worked perfectly on the Nucleo-F411RE.

Now the STM32 world opens up to great challenges.
