Note
When you use the Automatic emulation selection, note the following:
•
The EPSON or IBM emulation mode priority must be selected, because
the printer cannot distinguish between them. Since the factory setting is
the EPSON emulation mode, to use the IBM emulation mode you may
need to select it in the EMULATION menu in SETUP mode using the
control panel.
•
Try this function with your application software or network server. If the
function does not work properly, either select the required emulation
mode manually using the printer panel switches or use the emulation
selection commands from your software.
