18 Using the Printer
* The options available vary depending on the country of purchase.
** These settings take effect only when IBM 2380 Plus (for LX-300+)/ IBM 2381 Plus (for
LX-1170) emulation is selected.
Page length for tractor
This setting allows you to set the page length (in inches) for
continuous paper.
Skip over perforation
This feature is available only when continuous paper is selected.
When you select On, the printer provides a one-inch (25.4 mm)
margin between the last line printed on one page and the first line
printed on the next page. Because the program margin settings in
most applications override marginsettings made from the control
panel, you should use this setting only if you cannot set your top
and bottom margins using your application.

Auto tear off
When auto tear off is on and you are using continuous paper with
the push tractor, the printer automatically advances the paper
perforation to the tear-off position, where you can easily tear off
the printed pages. When the printer receives the next print job, it
automatically moves the unused paper back to the top-of-form
position and starts printing, so you can use all of the next page.
When auto tear off is off, you need to move the perforation to the
tear-off position by pressing the control panel button. See “Using
the Tear Off button” on page 38 for more information.
Auto line feed
When auto line feed is on, the printer accompanies each carriage
return (CR) code received with a line feed code, and the print
position moves to the next line. If the printer adds an extra line
after every carriage return, select Off.
Print direction
You can select bidirectional printing (Bi-D) or unidirectional
printing (Uni-D). Printing is normally bidirectional for faster
printing; however, unidirectional printing allows for precise
vertical printing alignment, which is useful for printing graphics.
Software
When you select EPSON ESC/P, the printer operates in the EPSON
EPSON ESC/P mode. When you select IBM 2380 Plus (for
LX-300+)/IBM 2381 Plus (for LX-1170), the printer emulates an
IBM printer.
0 slash
The zero character has a slash ( ) when this feature is turned on.
It has no slash (0) when this feature is turned off. The slash allows
you to easily distinguish between the uppercase letter Oand a
zero.

20 Using the Printer
High speed draft
When you choose On, the printer prints up to 413 cps (characters
per second) at 10 cpi (characters per inch). When you choose Off,
the printer prints up to 310 cps at 10 cpi.
I/F (interface) mode
The printer comes with a built-in parallel interface and serial
interface.
If your printer is connected to only one computer, select Parallel
or Serial 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.
Auto I/F (interface) wait time
This setting takes effect only when I/F (interface) mode is set to
Auto. This setting determines how long the printer waits when it
no longer receives data from an interface before it checks whether
a print job is being sent through the other interface. You can
specify 10 seconds or 30 seconds for the auto interface wait time.
Baud rate
Use this option to set the data transfer rate (baud) for the serial
interface. The baud rate is measured in bits per second (bps). See
your computer manual and software documentation for the
proper setting.
Parity
When this option is set to None, parity checking is disabled. The
parity bit, if used, provides a basic form of error detection. See
your computer manual and software documentation for the
proper setting.
