When set to 
Auto
, the printer analyzes the data and uses 
unidirectional printing for any lines which require vertical 
printing alignment.
Software
When you select 
ESC/P2
, the printer operates in the EPSON ESC/
P2 mode. When you select 
IBM 2390 Plus
, 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.
High speed draft
When you choose On, the printer prints up to 400 cps (characters 
per second) at 10 cpi (characters per inch). When you choose Off, 
the printer prints up to 300 cps at 10 cpi.
I/F (interface) mode
The printer comes with a built-in parallel interface and an 
interface slot in which you can install one optional interface. For 
information on using an optional interface, see “Optional 
interface cards” on page A-4.
If your printer is connected to only one computer, select 
Parallel
 
or 
Optional 
for the interface mode, depending on the interface you 
use. If your printer is connected to two computers, select 
Auto
 
(automatic) to allow the printer to automatically switch between 
interfaces depending on which one is receiving data.
