quality achieves its crisp appearance
by
printing each
hill' twice.
The
speed
of
near letter quality
print
is therefore
slower
I
hall
standard print.
If
you
are printing a
long
document, the
slower
speed can
make
a considerable difference.
III
some
cases,
you
may
want
to change
between
ncar letter quality
and standard
mode
without
using
BASIC
to send the MPS 1200 a
command.
For example,
when
using a
word
processor
you
may
want
to use a standard
mode
for quick notes
and
draft copies, and
ncar letter quality
mode
for finished products. For these applica-
tions, the
MPS
1200 provides a
way
to
turn
ncar letter quality
mode
on
and
off
using the
control
panel.
With
the
MPS
1200 on-line, hold the LF (line feed) switch
down
while pressing the
On-line
switch.
You
will sec the print head shift
twice, indicating that the
MPS
1200
is
now
in ncar letter quality
mode.
To
change back
to
standard
mode,
repeat the procedure.
This
time
the
print
head
jumps
just
once, indicating that the
MPS
1200 has changed
to
standard draft mode.
You
can usc the
control
panel to change
between
near letter quality
and
standard
mode
any
time
the on-line
and
ready lights arc lit,
even
if
the
mode
was previously changed
by
a
program
command.
For example,
you
can have
your
word
processor select near letter
quality
mode
automatically
by
including
ESC
"xl"
in its
printer
initialization string.
If
you
later
want
to
print
a quick draft copy,
you
can use the
control
panel to change to standard mode.
NOTE:
Some
word
processing
programs
send a reset code to the
printer
as
they start printing. This reset code will change the
printer
back to
draft
printing.
These
programs
won't
allow
you
to change to near letter quality using the control panel,
unless
you
can
make
the
word
processing
program
pause
dur-
ing
printing
so
that
you
can change modes.
CHARACTER
PRINT
WIDTH
The
MPS
1200 has three ways to change the
width
of
a printed
character:
(1)
changing the basic pitch,
(2)
expanding
the charac-
ters,
and
(3)
compressing the characters.
By
combining
these three
methods,
the
MPS
1200 can
print
in
eight
different character
widths
as
shown
in
Table
3.1.
