I believe that OS X only has drivers for Postscript printers.
There was this software package I once saw for Classic Mac OS that provided printer drivers for PCL printers. Unfortunately, I can't remember the name of it! :-( Perhaps someone can chime in with its name?
The only other way I know how to print to PCL printers from a Mac is to use Windows NT or 2000 Server with Services for Macintosh enabled. Microsoft implemented a Postscript to PCL converter in their software. There is probably a solution on UNIX servers as well.
