Default Command

The DEFAULT command changes the User-Default environment which is stored in NV-RAM and it is
activated following a PJL reset condition. The current print environment is not affected by the DEFAULT
command, but when a PJL reset condition happens, this command takes effect. This doesn't change the
current print environment, but is activated when a PJL reset condition happens.
It is recommended to restrict the use of the DEFAULT command when the printer is shared by several users
such as in a network environment. This allows use of the standard print environment and avoids changing
default features for each print job. If you have to change the default for a particular print job, use the SET
command.
Syntax
@PJL DEFAULT [LPARM : personality] variable = value [<CR>]<LF>
LPARM : Personality
This optional parameter is used to set personality-specific (emulation) environment variables.
variable = Value
This parameter is used to set one of the environment variables to the specified value. For example, the @
PJL DEFAULT RESOLUTION = 300 command sets the user-default resolution to 300 dpi. Use the @PJL
INFO VARIABLES command to obtain valid variables and the range of values for each variable. This
command can request the information directly from the printer.
Example
<ESC>%-12345X@PJL <CR><LF>
@PJL COMMENT Control Panel Defaults <CR><LF>
@PJL DEFAULT PAGEPROTECT = LEGAL <CR><LF>
@PJL DEFAULT LPARM : PCL SYMSET = PC850 <CR><LF>
@PJL RESET <CR><LF>
<ESC>%-12345X

Initialize Command

The INITIALIZE command resets the PJL Current Environment and User Default Environment variables to the
Factory Default values. I/O configuration values and the unsolicited status settings are not affected by this
command.
It is recommended to restrict the use of the INITIALIZE command when the printer is shared by several users
such as in a networking environment in order to use a standard environment and avoid having default
features changed by different print jobs.
Syntax :
@PJL INITIALIZE [<CR>]<LF>
Parameters :
The INITIALIZE command has no parameters.
The INITIALIZE command resets the following environment variables to the Factory Default values.
If any additional personality (emulation) is added to the printer, the printer may support more personality-
specific variables than the variables listed. In any case, the INITIALIZE command resets the PJL Current and
User Default environment values for all personalities to their factory default.
Example :
<ESC>%-12345X@PJL <CR><LF>
@PJL COMMENT setting to <CR><LF>
@PJL COMMENT factory defaults <CR><LF>
@PJL INITIALIZE <CR><LF>
<ESC>%-12345X
