The Apple Printer Utility that ships with the LaserWriter 16/600 PS enables you to configure the communication channels of the printer:
1) Verify the printer's configuration switch is in the up position
(p32 of the Apple LaserWriter 16/600 PS manual).
2) Launch the Apple Printer Utility and select the 16/600.
3) Choose Communication Configuration from the menu
4) Choose "Up Switch Position (Custom)"
5) Set the Netware mode to off.
When you quit the Apple Printer Utility, you'll have the option to send this change to the printer: click send.
