Print Environments At any time during printer operation, the printer’s current
feature settings are referred to collectively as the print
environment. When certain printer events occur, such as
the incidence of a printer language reset, RESET command,
or other PJL reset condition, the print environment settings
can default to the settings of other stored environments.
The printer constantly maintains four environments, which
are listed below in priority order:
Factory Default Environment (lowest priority)
User Default Environment
PJL Current Environment
Modified Print Environment (highest priority)
The Factory Default Environment holds the initial feature
values set at the factory, which can be used for default
values when a complete reset is needed. The User Default
Environment holds the settings modified with the
DEFAULT command, or set from the control panel. The
print environment defaults to the User Default values when
various printer conditions occur, such as the end of a PJL
job, a PJL reset condition, or when certain PJL commands
are executed. The PJL Current Environment contains the
current PJL feature settings. When a printer language is
entered or a new job begins, the PJL Current Environment
settings are loaded into the Modified Print Environment,
providing a base feature set which the application can
modify if needed. After a printer language is entered,
feature settings are recorded in the Modified Print
Environment.
Note HP LaserJet 4L, 5L, and 6L printers do not have NVRAM.
The PJL Default and Current Environment settings are
stored in RAM and are reset to the factory default values
during a power cycle.
