If I'm correct the Image Writer has an AppleTalk/LocalTalk port to connect to your Mac. There is a converter for this. I use it to connect my PM G5 to my Personal Laserwriter NT. I can also print from a network with this (connected to my router). The converter is called Farallon EtherMac iPrint Adapter. You can still buy them second hand, but they are a bit pricey. Also it takes a while to get a printjob done.
