Mode Switch
Mode Switch 1
The LaserWriter Pro has a ten-position rotary wheel that allows you to set the printer to
work in different communication environments. The first six positions (0–5) allow you to
select a set of fixed parameters for each of the communication channels. You cannot
change these sets of parameters using the PostScript operators. You may change the
remaining sets of parameters (6–9). See Chapters 2 and 3 for further information.
Table 1-8 shows the types of connections and the default parameter values for each
switch setting.
