6.2.6 Printer Type
This feature applies
to
Printer Controller mode and Copy mode and determines whether
or
not
the
terminal
will
pass
the
code seqµences for exiting these modes on
to
the
attached
printer.
When
this feature
is
set
to
the
OFF position,
the
ESC
code sequences for exiting Printer Con-
troller and Copy modes
will
be transmitted
to
the
printer. The CANCEL SELECT feature
will
then append
the
CAN
or
DEL code
to
cancel
the
effect
of
the
ESC
code on
the
printer.
This feature should be set
to
the
OFF position for full-line buffered printers.
When
this feature
is
set
to
the
ON
position, no codes
in
the
sequences for exiting Printer
Controller and Copy modes
will
be transmitted
to
the
printer. Thus, the setting
of
the
CANCEL SELECT feature
is
disregarded. This feature should be set
to
the
ON
position for
FIFO buffered printers,
or
printers with no buffer
at
all.
6.2.7
LF
Suppress
This feature determines whether
or
not
LF
codes received by
the
terminal are sent
to
the
printer.
In
the
ON
state, no
LF
codes
will
be sent
to
the
printer.
In
the
OFF state,
all
LF
codes
will
be
sent
to
the
printer. When this feature
is
set
to
the
ON
position, no codes
in
the
sequences for exiting Printer Controller and Copy modes
will
be transmitted
to
the
printer.
Thus,
the
setting
of
the
CANCEL SELECT feature
is
disregarded. This feature should be set
to
the
ON
position for FIFO buffered printers,
or
printers with no buffer
at
all.
The setting
of
this feature depends on how
the
attached printer reacts
to
received
CR
codes.
Some printers perform a new line function
(CR
& LF)
in
response
to
the
CR
code.
In
this
case,
the
LF
Suppress feature should be enabled
to
prevent double line spacing on the
printed data. Some printers perform only
the
carriage return function
in
response
to
the
CR
code.
In
this case,
the
LF
Suppress feature should be disabled
to
allow
LF
codes
to
be sent
to
the
printer.
6.2.8 Cancel Select
This feature applies
to
Printer Controller mode and Copy mode, (see Section 6.3.3) and
determines whether
the
terminal
will
automatically append and transmit
to
the
printer
the
CAN
code
or
the
DEL code immediately following
the
Control Sequence
to
exit Printer
Controller mode,
or
exit Copy mode.
Select
the
CAN
code
if
the
printer interprets
CAN
as
the
"Cancel function", and select
the
DEL code if
the
printer interprets
DEL
as
the
cancel function. The cancel function causes
the printer
to
erase its buffer.
6.2.9 Parity Select and Parity Enable
These two features determine if parity
is
enabled, and if it
is,
whether parity
is
odd
or
even.
Parity enable determines whether
or
not parity
is
enabled. Zero
(0)
corresponds
to
parity
disabled and
one
(1) corresponds
to
parity enabled.
Parity select determines whether parity
is
odd
or
even. Zero
(0)
corresponds
to
odd parity
and
one
(
1)
corresponds
to
even parity.
