Epson EPL-N3000 Reference Manual page 388

T. Margin
Sets the distance from the top of the page to the baseline of the
first printable line. The distance is measured in inches. The
smaller the value, the closer the printable line is to the top.
Text
Sets the page length in lines. For this option, a line is assumed to
be 1 pica (1/6 inch). If you change the Orientation, Page Size, or
T. Margin settings, the page length setting automatically returns
to the default for each paper size.
Auto CR
Specifies whether the printer performs a
carriage-return/line-feed (CR-LF) operation whenever the
printing position goes beyond the right margin. If this setting is
off, the printer does not print any characters beyond the right
margin and does not perform any line wrapping until it receives
a carriage-return character. This function is handled
automatically by most applications.
Auto LF
If you select Off, the printer does not send an automatic line-feed
(LF) command with each carriage-return (CR). If On is selected, a
line-feed command is sent with each carriage-return. Select On if
your text lines overlap.
Alt.Graphics
Turns the Alternate Graphics option on or off.
Bit Image
The printer is able to emulate the graphics densities set with the
printer commands. If you select Dark, the bit image density is
high, and if you select Light, the bit image density is low.
