INTERFACE
You can select an interface to receive your print data. When you
select AUTO, the printer automatically switches between interfaces,
depending on which one is receiving data first. When you select
USB, IEEE1394, or OPTION, only the selected interface receives your
print data. If no more print job is received, the printer returns to
an idle state after 10 seconds or more.
CODE PAGE
You can select a code page: PC437 (extended graphics) or PC850
(multilingual).
PAPER MARGIN
You can select margins for roll paper: T/B 15 mm, T/B 35 mm,
15 mm, or 3 mm.
