1.4.6 Emulation Mode Switch Function

This section describes the emulation mode switch function.

1.4.6.1 Emulation Switch by SPL

The four types of emulation switch functions described below are available on this printer.
EJL: Eson Job Language
This is EPSON's original language system. It is able to skip among various destinations, as shown
in Figure 1-11.
PJL: Printer Job Language
This is HP's original language, which is available with the LaserJet 4 printer.
It is able to skip among various destinations, as shown in Figure 1-11. The precise specifications for
this language are based on the HP LaserJet 4.
The figure below shows three types of mode switching.
Neither EJL nor PJL switches the mode directly. They first exit the current mode and return to EJL
or PJL. Then they enter another mode.

1.4.6.2 Intelligent Emulation Switch

The Intelligent Emulation Switch (IES) automatically switches the emulation switch mode,
depending on the data sent from the host computer through one of the interface channels. It is able
to switch between EPSON Script and other modes, as shown in the figure below.
