PJL Job Security Printers that support PJL job security: HP LaserJet 4/4M Plus, 4V, 4MV, 4Si, 4SiMx, 4000 series, 5, 5M, 5Si, 5SiMx, 5Si Mopier, 2100 series, 4500 series, 5000 series, 8000 series, 8100 series, 8500 series (5P, 5MP, 6P, 6MP, 2100: password only), The printers listed above provide two PJL security features: password protection and control panel lockout. HP LaserJet 4V/4MV and 5Si/5SiMx printers also provide disk lock protection. As discussed in Chapter 5, the DEFAULT command can be used to set a PJL password. Once the password is set, all succeeding jobs must issue the correct password in order to enable the DEFAULT and INITIALIZE commands. The password can only be changed from within a secure PJL job. On printers with a control panel, the control panel can be "locked out" so that users cannot modify settings using the control panel keys. This is accomplished using the DEFAULT command to set the CPLOCK variable to ON. The LaserJet 4V/4MV and 5Si/5SiMx printer's disk can be "locked" so that it cannot be formatted, fonts cannot be written to it, and disk fonts cannot be erased. For more information on CPLOCK, DISKLOCK and other security issues, see "PJL Job Security" in Chapter 5. A-50 Product-Specific Feature Support EN
