COMPUTER TO PRINTER
DATA
TRANSFERS
With
the
printer
selected
as
a
destination
device, you
can
copy
up
to
256
characters
of
a
data
string
from
the
computer
to
the
printer.
The
data
can
be
sent
in
either
binary
or
ASCII form,
depending
on
the
escape sequence used.
To
copy a
binary
data
string
to
the
printer
from
the
computer,
use
the
following escape sequence:
Ec
&p
<x>W
<data
5tring>
This
sequence
transfers
the
first
((x"
bytes
of
the
data
string,
in
binary
form, to
the
printer.
The
maximum
value
for
((x"
is
256.
To
copy
an
ASCII
data
string
from
the
computer to
the
printer,
use
the
following escape
sequence:
Ec
&p
W<
da
t a 5t
ring>
The
entire
data
string
is
copied.
The
string
is
terminated
either
by
an
ASCII
line
feed
character
or
by
the
256th
character.
PRINTER STATUS
It
is possible for a
program
to
determine
several
items
of
printer
status
information
using
escape sequences. These
items
are:
•
Whether
or
not
the
terminal
contains
an
integral
printer.
•
Whether
a
printer
error
exists
(no
paper
or
the
printer
top cover
is
open).
•
Whether
or
not
the
printer
is
busy.
•
Whether
the
last
command
sent
to
the
printer
was
completed
or
interrupted
(by
the
terminal
operator
pressing
the
1:1
key).
•
Whether
the
last
command
was
completed sucessfully
or
failed.
For
detailed
information
on
printer
status,
refer
to
the
Status
section.
An
alternative
method
exists
for
determining
the
status
of
the
last
command
sent
to
the
terminal.
After
issuing
a copy line, copy page, copy all, advance line,
or
advance
page
Ec
&p
sequence,
the
remote
program
can
determine
whether
or
not
the
operation
was
successfully
performed by
executing
an
I
NPUT
(BASIC language)
or
similar
instruction
that
requests
one
ASCII
character
from
the
terminal.
The
terminal
responds by
sending
an
((5", ((F",
or
((U".
An
((5"
indicates
successful completion,
an
((F"
indicates
that
the
operation
failed,
and
a ((U"
indicates
that
the
terminal
operator
interrupted
the
data
transfer
by
pressing
1:1.
These completion codes
cannot
be suppressed by configuration
parameters
or
any
other
means.
They
are
always
transmitted
and
your
programs
should include
input
commands
for
accepting
them.
