Hi Bodahnz,
Yes, the LW 16/600 is definitely supported under OSX (Apple supplies the Postscript printer descrition for it), so when you add it under X, it should automatically be detected and will select the proper ppd for you. you should be able to plug it in directly (using a crossover cable), or via an ethernet hub (this is the preferred method and they are very inexpensive)
good luck and great catch!
