Three emulation control command languages are available to
change the printer emulation:
Epson Job Language (EJL)
Printer Job Language (PJL)
Emulation Switch (ES).
Epson Job Language (EJL)
The Epson Job Language is an original Epson language. It can
perform the following operations for your printer:
Switching the printer emulation
Transferring the printer’s system information to the
computer
Entering the Printer Job Language (PJL) mode.
EJL can switch the printer emulation with a monodirectional
interface, but a bi-directional interface is required for the
computer to receive system information from the printer.
For more details on EJL commands, see the end of this section.
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.
