Apple ColorLaserWriter 12/600PS - Manual (Page 66)

If you have changed any of the settings and want to reset the printer to the
standard settings, move the configuration switch on the printer to the left-
hand position. Then restart the printer (using the Restart Printer command
from the Apple Printer Utility or by turning the printer off and then on).
Finally, return the switch to the right-hand position.
Why customize communication settings?
Though the standard communication settings work well for most
environments, you might want to customize communication settings to turn
off network interfaces you don’t need. For example, if you know the printer
will never receive a NetWare message over the network, you can turn off the
interface and stop the printer from sending out unnecessary NetWare packets.
How to customize communication settings
Change the settings with either of the following two programs:
m Apple Printer Utility on the Macintosh (see Chapter 2 for details on how to
install and use the program)
m Apple Printer Utility for Windows (see Chapter 3 for details on how to
install and use the program)
