User`s manual

The LocalTalk port is for connecting to any computer in a LocalTalk cable system.
In addition, the LaserWriter IIntx connector panel includes a 50-pin SCSI port for attaching a
dedicated hard disk. This port is not to be used for connecting to a Macintosh.
The LaserWriter IIntx has one expansion slot for ROM expansion.

Downloading a PostScript program can change the switch con-figuration. If any switches are
subsequently changed, the configuration changes to match the new switch settings. If the
LaserWriter IInt will not print, check the switch settings and change them as required. If the
settings are correct, reverse the switch 1 setting, wait 30 seconds, and switch it back. Then
turn the power off and on again. The test page should show the correct choice of either
PostScript or emulation, and the correct port-either LocalTalk or serial. Do not connect
LocalTalk if using serial port configuration.
