Depends on the negative... if I really like a picture and I'm in the mood for darkroom work, it gets printed as soon as the film is dry. Sometimes I go out shooting in the morning, develop in the afternoon and print at night - now tell me one more time, that film photography is slow
On the other hand, there are a lot of negatives that aren't printed for months. They're not necessarily less important pictures, but less urgent. Some pictures also need a little time before I actually like them enough to print.
From time to time, I also like to browse through all my negatives and see if any are worth printing again... some pictures are so fascinating to me, that I can print them again and again months or years after taking the picture. As I do a lot of dodging, burning and contrast adjustements, the prints also turn out differently in different printing sessions. For example, I used to like a very high-contrast (always grad 4-5) look on glossy paper, but now I prefer more balanced prints on warm-tone FB paper and very intense dodging and burning (to the point were it becomes almost "painting with light") I also used to print 15-20 different negatives on postcard formats in one night, but now it's more like 3-4 big prints.
It's interesting to see the different results that can be obtained from the "same" picture just by changing the printing process... the print can't really be perfect right away. Some prints need years to become just right in my eyes and that's why I never put any negatives in the "printed and ready for final archival" folder.
If I ever become famous, art collectors will hate me, because there are dozens, sometimes hundreds of prints from the same negative, some with variations so slight, nobody but myself would even notice....
