Connecting to a Macintosh
What You Need
To connect your printer to a single Macintosh, you need the items
shown in the illustration below:
■ Two PhoneNET-type transformer boxes
You need one with a DIN-8 connector for the printer port
and one with the connector required by your Macintosh
(usually a DIN-8).
■ RJ11 (telephone) cable
■ Terminating resistors—probably two
If you’re replacing a printer already connected to a Macintosh, you
probably already have this equipment.
