6.5.

Reset Command 

The 

PJL RESET

 command resets the PJL Current Environment variables to the User Default values.  

Use this command at the end of any PJL jobs in which the 

PJL SET

 command was used.  

Syntax  

@PJL RESET [<CR>]<LF> 

Parameters  



The 

RESET

 command has no parameters 



When an application such as a Spooler or Print Data Generator uses the 

SET

 command to set PJL variables,  

the application has to conclude with the 

RESET

 command (before the 

UEL

 command) to return the 

variables to the previous state.  



The 

RESET

 command resets the environment variables to their user default values. 

In any case, the 

RESET

 command resets the PJL Current settings for all personalities to the User Default 

values. 



Use the 

@PJL INFO VARIABLES

 command to obtain valid variables and the range of values for each 

variable. This command requests this information directly from the printer. 

Examples  

<ESC>%-12345X@PJL <CR><LF> 
@PJL COMMENT Reset variables to <CR><LF> 
@PJL COMMENT control panel settings <CR><LF>

6.6.

Set Command 

The 

SET

 command enables you to change the value of PJL Current Environment variables during a PJL job 

until a PJL reset condition resets the default values. 

Use this command to make a job-specific environment. 

Syntax 

@PJL SET [LPARM : 

personality

] variable = 

value

[<CR>]<LF> 



LPARM : 

Personality

This optional parameter is used to set personality(emulation) -specific environment variables.   



variable = 

value

This parameter sets one of the environment variables to the specified value. 
For example, 

@ PJL SET RESOLUTION = 300

 command sets the current resolution to 300 dpi.   For a list 

of variables and values, see the following table. 



Use the 

@PJL INFO VARIABLES

 to obtain valid variables and the range of values for each variable. This 

command can request this information directly from the printer. 

Parameters 



The printer control panel setting values and the feature settings stored in NV-RAM are not affected by the 
values modified with the 

SET

 command.  



The setting values selected with the 

SET

 command are valid until the next PJL reset condition occurs. 



If the SET command is used in a job, use the 

RESET

 command after the job to reset the printer to User 

default settings.
