This
command
sets the line spacing to n/216
of
an inch, adjusting
the line spacing to
1/3-dot
increments.
To
use it, send the printer
chr$(27)
"3"
followed
by
the ASCII code for the
number
of216ths
you want,
from
0 to 255. For example, chr$(27)
"3"
chr$(24) will
change the line spacing
to
24/216
of
an inch
or
9 lines per inch.

Spacing
with
Secondary
Address 6
There's
another
way
to change line spacing,
by
using the secondary
address
of
the
OPEN
command.
A secondary address value
of
6
controls the
number
of
n/216
"steps"
between successive lines
of
print.
The
number
you
give
is
divided into 216 to determine the
number
of
lines per inch.
Thus,
a value
of
27 produces eight lines
per inch, 72 produces three lines per inch, etc.
The
default value
is
36,
which
produces 6 lines
per
inch.
The
following illustrates
spacing determined by a secondary address:
