Technical Specifications for the LaserWriter Select 360 can be found at the AppleCare database site:

According to the specs the LaserWriter 360 has an AppleTalk port and RS-232/RS-422 serial
Centronics parallel port hich is where your friend connected the PC to the printer. The new iMac will be connected to the AppleTalk port. Mac OS 10.2 and up includes drivers for the LaserWriter 360. To connect the 360 to your FP iMac you will need an Ethernet to AppleTalk (LocalTalk) bridge. Asante makes such a bridge (Asante calls their's AsanteTalk). I believe there are others available as well.
If you have no other ethernet devices connected to your iMac you can connect the bridge directly to your iMac with an Ethernet crossover cable. The AsanteTalk bridge comes with that cable. If you have other ethernet devices connected to your iMac or if you want to network 2 or more Macs together then you'll also need an ethernet router or switch. If you're connecting to a router or switch do not use the cross over cable but use regular ethernet cables instead.
One caveate that seems to be a known problem in that it is listed in the AppleSupport boards is that when printing to any printer connected to an AsanteTalk bridge (and most likely to other Eternet to AppleTalk bridges as well) you will get a Printer Error alert after selecting Print in the Print dialog box. After a short wait, or by clicking OK in the alert box, the alert box will go away and printing will occur normally. I'm not sure why this happens but it may be related to the slow throughput of the bridge. I use an AsanteTalk bridge connected to my LaserWriter IIf and printing occured OK under OS X 10.1.5 but I get the Error alert with 10.2 and now 10.2.1.
