Environment Commands

Introduction
Hewlett-Packard printers have many features you can set
using printer commands or by pressing control panel keys.
Since previous jobs can change feature settings to
unwanted values, applications should set printer features
affecting the print job to a desired state at the beginning of
the job.
Setting features to a desired state is easily accomplished
using a combination of PJL and printer language
commands. This chapter describes sets of printer features
known as print environments, and the PJL commands you
use to set printer features to a desired state, such as:
DEFAULT sets the default value for environment
variables, storing these values in non-volatile RAM.
INITIALIZE resets the current and default PJL
variables to the factory default values.
RESET resets the current PJL variables to the default
values.
SET sets an environment variable to a specified value
until the next PJL reset condition.
Note
For a list of default feature settings, see Appendix A.
