As said above, optical printing from negatives is pretty much dead these days, I only know of one lab that still does it exclusively that way. The main advantage of scan and laser/LED printing is that you can easily correct for white balance, underexposure etc whilst with the traditional optical method it was possible to correct for both but for it took much longer and was more difficult so few labs offered it except for pro labs (hence why you used to get little notes back with the prints about it being the 'wrong film' when you shot daylight film under tungsten lights and got an orange cast)
These days the scanners used by pro labs and in minilabs are so good (much better than anything consumer based) that its usually not possible to tell the difference between an optical and laser/LED print.
