Printer Job Language (PJL)

The Printer Job Language mode uses PJL commands to change printer emulations. Because the PJL mode emulates the HP LaserJet series IIP (ActionLaser 1000) or III (ActionLaser 1500) printer PJL feature, you can use software written for that printer when it is shared in a network environment.

You can also enter the EJL mode from the PJL mode. For information on the PJL commands, see Appendix B.
