Warning
:
If you choose a non-LocalTalk setting for the LocalTalk (8-pin) port while the printer is connected to an AppleTalk network, you can do permanent damage to devices on the network! Settings 1, 4, 5, and 6, (and possibly 9, since you can customize 9) are non-LocalTalk settings for the 8-pin port. Before you choose one of these settings, disconnect any LocalTalk connector box connected to the printer.
If you have a non-Macintosh computer that requires special settings to work with the Personal LaserWriter NTR, you can choose a different group of settings. You use the ten-position push-button switch on the back of the printer to choose a group of settings.
If you need to change the setting, check the following table for the switch position that corresponds to the setting you need. If you need additional settings and have access to a Macintosh computer, you can program position 9 using the LaserWriter Utility software.
