I/F (interface) mode
The printer provides a slot for an optional interface in addition
to its built-in parallel interface. You can choose Auto
(automatic), Parallel, 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 or Optional, depending on which interface your
computer uses.
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.
0 slash
The zero character has a slash (0) 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.
High speed draft
When high speed draft mode is on, you can choose between
two different font sizes: 10 cpi (characters per inch) or 12 cpi.
When you select 10 cpi, the printer prints up to 410 cps
(characters per second); at 12 cpi, it prints up to 455 cps. When
high speed draft mode is off, the printer prints in normal draft
mode (310 cps at 10 cpi).
