Introduction
The printer has an extensive set of system parameters that control
its behavior. These govern the baud rate, the communication
protocol of the serial channels, the printer’s margins, the timeouts,
and other similar functions.
There are two kinds of system parameters:
■ Volatile - parameters that remain in effect only through the
processing of a single file.
■ Persistent - parameters that persist even when the printer
is turned off.
This chapter documents both kinds of parameters. Before changing
a parameter, read all the material relating to it first. This helps you
avoid mistakes that might have undesirable effects on the printer’s
software.
In addition, read chapter 10, “PostScript: Technical Overview”
before you read this chapter.
NOTE: Most operations detailed in this chapter can be
accomplished quicker and more easily through the PS
Executive Series Utilities.
