CHAPTER 5 PJL - 16
The diagram below illustrates how the environments interact and how the modified print environment is
affected.
FACTORY

USER DEFAULT ENVIRONMENT
PJL CURRENT ENVIRONMENT
MODIFIED PRINT ENVIRONMENT
@PJL INITIALIZE
@PJL RESET
LANGUAGE RESET, @PJL ENTER, OR ANY LANGUAGE SWITCH
CONTROL PANEL
OR @PJL DEFAULT
@PJL SET
6.1.2. PJL reset conditions
The result of PJL reset condition is different from that of a printer language reset (for example,
ESC E
). Printer
language reset loads the PJL Current Environment values into the Modified Print Environment. PJL reset
conditions load the User Default values into the PJL Current Environment, which are then loaded into the
Modified Print Environment.
PJL reset occurs on the following events.
1.
Power on
2.
UEL
command (when not between a
JOB
and
EOJ
command pair)
3.
@ PJL INITIALIZE
command
4.
@ PJL RESET
command
5.
@ PJL JOB
or
EOJ
command
6.
Other printer-specific events
7.
Reset from Control Panel
8.
Language specific exit command
9.
Emulation switching command
6.1.3. Remember these points about environments
Remember the following points when you use PJL to set the printer to a desired state.
1. The current feature settings are the same as the control panel values ( or values in the remote printer
console program) when beginning a PJL job.
2. The current feature settings (Modified Print Environment) become the same as the PJL Current
Environment when the printer enters a printer language. The feature settings are modified by the printer
language command once a printer language is started. All other settings are overridden by printer
language commands.
3. The
SET
command changes the PJL Current Environment settings. These settings are effective until the
next PJL reset condition.
4. Control Panel settings, the remote printer console program settings or the
DEFAULT
command changes
the User Default Environment.
5. Printer language commands change the Modified Print Environment. These settings are effective during a
printer language job. The PJL Current Environment settings are loaded into the Modified Print
Environment by a printer language specific reset, for example,
ESC E
for PCL.
