The standard lpd that you get when you turn on spooling in /etc/rc.conf.

Thanks for the feedback.  I've been using lpa0 with some success, but 
I'll ask about the problems on the Mac port lists.  Enscript seems to 
work with it, but the activity light is left blinking when the job is 

Would I be better off with the patched ulpt driver?  I guess that's a 
stupid question unless I can get lpt working.  Polling has to hog the 
system badly.
