affected.

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.
