NOTE: The previous sequence can
be
shortened
by
combining
sequences that have the same two characters following the
Ec
character and by eliminating unnecessary zeroes:
Once you have selected
the
font
as explained above, selecting a
font
with similar characteristics only requires changing the
characteristics
that
are different.
For
example,
to
specify a
font
differing only in style (upright)
and
stroke weight (bold), only
the
following escape sequence would be required:
or
shortened sequence: Ec{ss3B
Note
that
after a
font
has been selected, the printer "remembers"
what
was last specified.
When
selecting a new font, the printer
compares the specified characteristics with those last specified,
not
with those
of
the
font
last selected.
For
example,
if
you
!>pecify
an
italic
font
and
an upright
font
is
selected (because,
for
example, no italic
font
was available),
the
printer stores
the
style
last specified (italic). Therefore, when you wish
to
specify
another
font, if you
do
not
wish
to
select an italic font, you must
specify the upright style.
S'VITCHING
BET'VEEN
PRIMARY AND
SECONDARY CHARACTER FONTS
Once you have specified
your
primary and secondary fonts
as
explained above, you may switch between them using the Shift
Out
(So)
and
Shift In
(~)
control
codes. A Shift Out selects
the
secondary
font
and
a Shift In selects the primary font.
