GRAPHICS HARDCOPY OPERATIONS
There
are
two methods
of
obtaining
a hardcopyof
the
contentsof
graphics
memory. One
method
uses
the
function keys
and
graphics keys on
the
keyboard.
The
other
method
uses
escape
sequences which
may
be coded
into
a program
running
on a
host
computer.
The
hardcopy
may
be
output
from
the
optional
integral
printer
or from
an
external
printer
connected to
the
external
printer
port
at
the
rear
of
the
terminal.
When
the
optional
integral
printer
is selected
as
the
output
device, a dot-by-dot
transfer
of
the
graphics memory is
made
on
thermal
paper.The image
is
14.5
cm
by 11 cm(5.75 by4.25 inches)
centered on
the
paper.
The
transfer
takes
approximately 30 seconds.
The
external
printers
that
can
be usedfor graphics hardcopy
are
the
HP
2671G,
HP
2673A,
HP
2932A,
and
HP
2934A.
If
the
terminal
is equipped
with
the
alternate
peripheral
interface,
the
HP
82906A
can
also be used.
Plotters
that
can
be
used
for graphics hardcopy include
the
HP
7220C/T,
HP
7221C/T,
HP
7580B,
and
HP
7585B. When equipped
with
the
alternate
peripheral
interface,
the
HP
7470A,
HP
7475A,
HP
7580B,
HP
7585B,
and
HP
9872C/Tcan be used
as
graphics
hardcopy devices.
Initiating A Transfer From The Keyboard
The
G.
COpy
key
on
the
graphics/numericpad
initiates
the
graphicstransfer.
The
keypad
must
be
in

function to be performed
.•
NUM
PAD
toggles
the
function of
the
keypad
between
graphics mode
and
numeric
mode.
Pressing
the

no valid destination device
has
been specified.
The destination(s)
may
be selected by pressing
_,
device
control,

printer.
TO
AL
T
PRT
selects
an
external
printer
on
the
alternate
peripheral
interface.
Using The
Ec
& p Escape Sequences
Coding a
program
to
transfer
graphics
data
either
to
the
integral
printer
or
to
the
external
printer,
or
both,
requires
selecting
the
graphicsmemory
