PJL Current Environment
The PJL Current Environment is the set of features
that is active when a PJL job is entered. As soon as a
PJL job is entered, the PJL Current Environment set-
tings are the same as the User Default Environment.
Applications then can modify the PJL Current Environ-
ment values using the PJL SET command. The PJL
Current Environment provides a base set of values
when entering a printer language.
PJL Job
A PJL job is any print job containing PJL commands.
Properly formed PJL jobs always begin and end with
the UEL command.
PJL Reset Condition
A PJL reset condition prompts the printer to load the
User Default values into the PJL Current Environment,
which are then loaded into the Modified Print Environ-
ment. In this document, the term PJL reset condition
refers to any of the following events: a power-on, UEL
command (when not between a JOB/EOJ command
pair), the @PJL INITIALIZE, @PJL RESET, @PJL JOB,
or @PJL EOJ commands. Also included are other
printer-specific events, such as control panel reset,
a printer language-specific exit command (when not
between a JOB/EOJ pair), such as ^D for PostScript,
and data stream idle timeouts (see Appendix A for infor-
mation about job boundaries and timeouts for the
HP LaserJet 4 and 5 printer families.)
