(line-feed command).
LF
CHR$(10)
The line feed is set to 1/6 inch if DIP switch 1-5
is "on" upon "power up" or printer reset. If DI P
switch 1-5 is "off" the line feed will be 1/8 inch.
The size of the line feed can be changed using
the codes listed below. When DIP switch 2-4 is
"on;' a line feed is automatically generated
when the printer receives a CR code CHR$(13}.
Change the line feed to
a
pre·set value.
ESC "n"
CH R$(27) CH R$(m)
When this command is sent to the printer, the
size of the line feed is changed according to
the value of "n" (CHR$(m)).
For "n"
=
"0" (m
=
48),
successive line feeds become 1/8.
For "n"
=
"1" (m = 49),
successive line feeds become 7/72.
For "n"
=
"2" (m
=
50),
successive line feeds become 1/6.
