Viewing and changing communication settings
The standard communication settings of the LaserWriter 12/640 PS work for
most environments. To make sure the printer is set up to use the standard
settings, check that the communication switch on the left side of the printer is
in the Normal (in) position. The switch is located below the interface
connectors.
You can view and change the standard communication settings for the printer
with the Apple Printer Utility. The NetWare, TCP/IP, and Parallel interfaces
are set to AutoSelect, which turns on automatic language sensing. Automatic
language sensing allows the printer to receive information over the network
and determine which page-description language—PostScript or PCL5—is
required.
