Configuring For Port Switching - IBM 6400 Operation Manual

Configuring for port switching

If you will be port switching with the MPI,
you must set the printer emulation used by
the PC application to match the emulation
you have set in the printer.
For example, when you have set the printer
emulation to 6400-Epson, your host ASCII
application, should use a standard Epson
print driver.
When you have set the printer emulation to
the P-Series emulation, your application
should use a standard P-Series printer
driver.
