6. Automatic Printing
Automatic
printing will
occur
under 3 conditions. In
order
to
understand
exactly
what's
happening,
you
have
to
have a little knowledge
about
how
your
printer
works. First, each printed character
is
made from 6 rows
of
dots.
Next,
you
can have
up
to
80
characters per printed line (spaces
count
as 6
dot
positions
just
like letters and numbers). This means
that
there are
a
total
of
480
dots
per line. Now
you're
ready for the 3
conditions.
a. When
the
buffer
fills
up
during
the
input
of
data.
b. When
your
printer
"sees"
that
you
have used
up
more
than
the
480
dots
per
line
that
was described above.
c. When
both
a and b
happen
at the same time.
What will
happen
when these conditions occur?
a.
When
the
buffer
fills during printing, it prints
out
everything it has
been storing
onto
your
paper. But
...
it remembers where it stopped
printing so
that
it can continue from
that
point,
when
and
if
you
want
to.
Or,
it
will
print
again when
you
fill the
buffer
again.
b. When the printer uses
up
more than
480
dots,
then
it
prints
out
the
line and
then
stops and tells
you
that
it's READY for more
information.
c. When
both
a and b occur,
your
printer will
"dump"
only the first
80
characters and
print
them.
Then it will move
to
the
next
line. At this
point,
the
printer
will
do
2 things: 1)
It
will hold any characters
that
have been left
in
the
buffer and add to them; 2)
It
will give
you
a
READY for more information statement.
