Radio Shack TRS-80 Operation Manual page 27

This
is
a useful feature
if
you
need
to stop printing temporarily
at a certain
point
in
the
file
for
any
reason.
For
instance,
suppose
that
you wish
to print
some
text
and
then a
large table
of
figures
which
requires
you
to
change
printer
paper from
13" to
15".
All
you have
to
do
is
define a Print
Control
Code
for the
PAUSE
sequence
(with
its
Hex.
value, 1B25) using exactly the
same
procedure
as
described
in
Using
PTC-64
Special Characters.
Then
simply
insert
the Print Control
Code
at
the
appropriate place
in
your
file.
This
will
cause the printer
to
stop temporarily
(after
having
printed
any
text
previous
to
the
PAUSE
code). You'll hear a
beep
to
announce
the printer has stopped.
You may
then
change
the paper. Printing
will
resume
only
after
pressing the
PAUSE
key
on
the Printer Controller.
