Software
When you select ESC/P, the printer operates in EPSON ESC/P
mode. When you select IBM PPDS, the printer emulates an IBM
printer.
0 slash
The zero character has a slash ( ) when this feature is on; it has
no slash (0) when this feature is off. The slash allows you to
easily distinguish between the uppercase letter “O” and a zero.
I/F (Interface) mode
The printer has built-in parallel, serial, and USB interfaces in
addition to a slot for an optional Type B interface card. You can
choose Auto (automatic), Parallel, Serial, USB, or Optional for
the interface mode. When you select Auto, the printer
automatically selects the interface that is receiving data, and
uses that interface until the end of the print job. The Auto setting
allows you to share the printer among multiple computers
without changing the interface mode.
If only one computer is connected to the printer, you can select
Parallel, Serial, USB, or Optional—depending on which
interface your computer uses—to lock the other ports, if
necessary.
Auto I/F (Interface) wait time
When the printer is in the auto interface mode and it receives no
data from the currently selected interface for the amount of time
specified with this setting, it determines which interface is
receiving data and switches to that interface. You can specify
either 10 seconds or 30 seconds for the auto interface wait
time.
