and Hn
=
0 when both
t-unit
and
g-unit
parameters
are
spec-
ified.
If only the
t-unit parameters
are
specified,
then use
Ln
=
2
and
Hn
=
O. The number of
parameter
bytes is 256 times
Hn
plus
Ln.
The t-unlts
parameter is a two-value parameter indicating
the
ver-
tical index increment
used by
subsequent
ESC
A
commands.
When the printer is initialized
I-units
is set to 72.
A
value of zero
will not change the current
setting.
Valid values are given in the
table
below.
The
g-unlts
parameter is a two-value parameter indicating
the
vertical
index
increment used by subsequent ESC 3
(Set
Graphics
Line
Spacing),
and ESC J (Variable Line Feed)
commands.
When
the printer is
initialized,
g-units
is set to
216.
A value of zero will
not change
the
current
setting.
The values in
the
following table represent the valid values fo
r
both the t-units and g-units
parameters.
Other values
result
in no
change.
