INTRODUCTION
Now,
hear
this! -
to
all
microprocessor
users
who
require a low-cost,
medium-speed,
impact
printer
with
system
interface.
The
IMP-00/812(E)
is
the
printer
you
want
for
IMP
and
PACE
Prototyping
Systems. Using
appropriate
software,
this
printer
provides an
output
of
100
characters
per
second
at
a
maximum
line
width
of
80
characters;
the
characters
are
imprinted
with a
standard
9-bt-7
dot
matrix.
For
80-character
lines,
the
average
speed
is
50
lines
per
minute;
for
lines
with
less
than
30
characters,
speeds in
excess
of
150
lines
per
minute
are
obtainable.
Special
paper
is
not
required,
and
one
original
and
one
to
four
carbon
copies,
all
very clean
and
legible, can be
produced.
The
paper
is
sprocket-fed
and
can be varied in
width
to
a
maximum
of
9Y:!
inches.
As
an
option,
special
character
sets
can
be
implemented,
and,
under
software
direction,
elongated
boldface
characters
can
also be
printed.
The
printer
is
completely
self-contained.
