Reversing
a Field
This function
inverts
the dot matrix
to
produce
the
effect of
white
on
black.
DO NOT
use
this
mode
of printing for
more
than
five
consecutive
lines
since
extended
printing
in
this
mode
will
damage
the
print
head.

The
Carriage Return
If
you
attempt
to print
more
than 80 characters
on
a
line,
a
Carriage Return with Line
Feed
will
be
forced
and
the overflow characters
will
be
printed
on
the next
line.
If
you
transmit a
Shift
Carriage Return
($8D),
a Carriage
Return without Line
Feed
is
executed. This allows
overprinting
on
a
line.
A
Carriage Return turns
off
reverse
field,
character
enhance and
the
quote mode.
Quotation
Maries
If
an
odd number
of
quotation
marks have been
transmitted, control
characters are
made
visible.
This
can be
particularly useful
when
you
are
making
a
listing
of
a
BASIC
program
containing cursor
control characters
in
quotation marks.
