I own a "workhorse" Apple LaserWriter 4/600 PS bought in 1996. I have manual but have lost software. My son has a Macbook Pro. Will the printer be compatible w/ macbook pro? (I'm assuming it will). How can I get missing printer software he needs to load on his macpro in order to use the printer? Anything else I need to get him for this all to work? He's in college and going through his grandparents ink! Me, my son, and grandparents all on fixed incomes so cheapest solutions most welcome.
