Making a print is very easy, but making a very good print is very hard.
The process is very similar to making developing a negative.
The negative goes in the enlarger, and shines onto a piece of paper. You start by making a test strip, where you expose different parts of the paper for different times, to find the best exposure. Then you make a print, by exposing the paper for an amount of time.
You then place the paper in the developer (normally for 60 seconds) this is when the image appears. It then goes into the stop, to stop the deveopment, then into the fix for a couple of minutes, to fix the image to the paper.
The final step is to wash in running water, then hang up to dry.
