HP PCL/PJL reference - Printer Job Language Technical Reference Manual

EN Environment Commands 6-39
INITIALIZE Command
The INITIALIZE command resets the PJL Current Environment and
the User Default Environment variables to their Factory Default
values. This command does not affect the I/O configuration values,
some of the configuration values, and the unsolicited status settings.
Use the INITIALIZE command to set the printer environment values to
their factory default state, such as when you move the printer to a new
installation site. (This command is not intended for frequent use,
since it resets most environments and control panel settings.)
For printers that support the PASSWORD variable, the INITIALIZE
command will not take effect unless it is used within a secure job (if a
password is in use, a secure job is one that contains the correct
password in the JOB command).
Note In situations where the printer is shared by several users, such as
networks, restrict the INITIALIZE command. This recommendation
allows a standard print environment to be used and avoids having
default features changed by different print jobs. In this way, jobs may
be successfully printed in any order since they are not affected by
settings from previous jobs.
Syntax:
@PJL INITIALIZE [<CR>]<LF>
Parameters:
The INITIALIZE command has no parameters.
Comments:
The INITIALIZE command resets the following environment variables
to their Factory Default values.
Note Because personalities can be dynamically added to some HP
LaserJet printers, these printers support more personality-specific
variables than those listed here. In any case, the INITIALIZE
command causes the PJL Current and User Default environment
values for all personalities to default to their factory default state.
