Many people misunderstand the word “develop” – it does not mean “make a paper print” of a photograph.
When you shoot on film, you take the film out of the camera, and the film then has to be developed (and “fixed”) in total darkness. That gives you the negative, which is then not altered unless you damage it.
So the scanner you buy will simply digitise the negs – what you do with the files after that is a further set of choices.
The negative can then be printed photographically (another operation in total darkness), or you can scan it. When you have the digital file from the scanner in your computer you can look at the picture on your computer screen, or you can get it printed by a computer printer, or you can take the file to a photo lab for darkroom printing.
