PJL Job Security
HP LaserJet 4/4M Plus, 4V, 4MV, 4Si, 4SiMx, 4000 series,
5, 5M, 5Si, 5SiMx, 5Si Mopier, 5P, 6P, and 6MP printers
support the following types of PJL security:
Password protection of default feature settings—this
type of security prevents applications from modifying the
printer’s default feature settings unless the correct
password is specified.
Control panel lock—prevents users from modifying
control panel settings using the control panel keys.
Disk lock (LaserJet 4V, 4MV, 4000 series, 5, 5M, 5Si,
5SiMx, 5Si Mopier only)—prevents writing to the
printer’s disk (or flash memory [LaserJet 5/5M printer]).
File system initialization—for printers with a PJL file
system, the FSINIT command will not initialize the file
system unless specified in a secure job.
All types of security are set using the DEFAULT command
and queried using DINQUIRE or INQUIRE.
Password Protection
of Default Feature
Settings
You can use a password to protect the printer’s default
features by sending the @PJL DEFAULT PASSWORD =
number command, specifying a number between 1 and 65,535
(the 0 value disables password protection). Once password
protection is enabled, the DEFAULT or INITIALIZE
commands are disabled unless the correct password is
specified in the JOB command. Printer languages, such as
PCL and PostScript, are also prevented from changing default
variables.
Secure PJL jobs are able to use the DEFAULT and
INITIALIZE commands (or printer language commands) to
set default features, including the value of the PASSWORD,
CPLOCK, and DISKLOCK variables, until the next EOJ
command is received.
