You are correct about the Windows situation.  In fact 3rd party drivers/RIPs 
are generally very expensive and in most cases require specialized work flows.  
The situation for *nix and OS/X users is somewhat different because the 
GutenPrint drivers have many features in common with high end RIPs and it is 
steadily getting more of this type of functionality over time.  There are many 
*nix and OS/X GutenPrint users who use it like it was an ordinary printer 
driver who do not even know how powerful it is.   With a specialized front end 
like PhotoPrint the GutenPrint drivers can also be used in Windows although 
you would need to do all of your printing outside of the normal apps print 
dialogs to use it (IE. GutenPrint + PhotoPrint = a RIP like environment).
