and
all

Printers that
do
not require lpc:
26-1150,
1152, 1153, 1154, 1159,
and
the
a
version of
lpiii
(26-1 156A).
You must
load
the
lpc program
before you
load an
application
program. The
easiest
way
to
do
this
is
to
copy
lpc onto your data/program
diskette
and
then
use
the
auto
command
to
load lpc
automatically each time you
use the system.
For
instance, type:
COPY LPCsi
:0
(ENTER)
Then,
to
make
lpc an
auto command
on
the diskette, type:
AUTO LPC/CMD
CENTER!
Whenever
you
use
your program
diskette,
lpc
will
automatically load
into
memory
and you can
use the
program
as usual.
lpc
locates into the highest available memory.
There
is
no need
to set
MEMORY
SIZE
to
protect lpc.
It
"hides"
itself.
However, you
still
need
to set
memory
if
required
by your
application program, lpc
will
be
killed
if
the
clear
command
is
used.
Warning: Once
the
lpc
utility
program
is
loaded and
installed,
you
should
not
reload
it
except
after a reset.
Reloading
re-installs the
program and
uses
up more
space each
time! lpc
will not execute
if
the Printer has been
routed elsewhere.
Also,
if
lpc has been executed and
then
the Printer
is
routed elsewhere,
the
original printer driver
will
regain control
after the routing.
