Switch settings, from EK-OLN03-RM-002, "LN03 Programmer Reference
Manual". I presume that SP2-4 (Autowrap) will no longer have any
function because of the PostScript upgrade.

2.4.1 Switch Pack 1 (SP1)
Switch pack 1 controls the printer's interface type, baud rate,
and data format (7 or 8 bits). Switch pack 1 also enables or
disables parity checking.

Interface Type (SP1-1)
This switch is set to match the data communications interface,
either serial or parallel (future option).

SP1-1 Function
On Parallel interface
Off Serial interface (factory setting)

Baud Rate (SP1-2, SP1-3, and SP1-4)
These switches select the transmit/receive speed the printer uses to
communicate with the computer.

SP1-2 SP1-3 SP1-4 Baud Rate
Off Off Off 1200
Off Off On 2400
Off On Off 3600
Off On On 4800 (factory setting)
On Off Off 7200
On Off On 9600
On On Off 19200
On On On 19200

7 or 8 Data Bits (SP1-5)
This switch is set to match the character format used by the host
computer, either 7 or 8 data bits.

SP1-5 Function
On 7 data bits
Off 8 data bits (factory setting)

Parity Enable (SP1-6)
This switch enables or disables parity. If enabled, the printer
checks the parity bit selected by switch SP2-1.

SP1-6 Function
On Parity enabled
Off Parity disabled (factory setting)

2.4.2 Switch Pack 2 (SP2)
Switch pack 2 controls the type of parity bit checked, the printer's
identification (ID) response, the autowrap feature, and XON/XOFF or
restraint protocol.

Parity Bit (SP2-1)
If switch SP1-6 is on, switch SP2-1 selects the type of parity bit
the printer checks for and sends.

In 7-bit mode, the printer can

- check for odd parity and send a space parity bit, or
- check for even parity and send a mark parity bit.

In 8-bit mode, the printer can only check and send even or odd
parity. Switch SP1-5 selects 7-bit or 8-bit mode.

SP2-1 Function
       7-Bit Mode 8-Bit Mode
On Check odd, send space parity. Check and send odd parity.
Offf Check even, send mark parity. Check and send even parity.

Device ID Select (SP2-2 and SP2-3)
These switches set the printer identification (ID) response to LN03,
LQP02, or LA100. These switches are usually set for an LN03 ID
response, except when the printer is connected to a system that
requires an LQP02 or an LA100 ID response. These switches do not
affect the printer's response to control functions.

SP2-2 SP2-3 Device ID
Off Off LN03 (factory setting)
Off On LQP02
On Off LA100
On On LN03 (same as factory setting)

Autowrap (SP2-4)
This switch selects the method of controlling a line of characters
that exceed the right margin. If you select no wrap, the printer
drops characters exceeding the right margin. If you select autowrap,
the printer prints characters exceeding the right margin on the next
line.

The printer remains in this state, unless you send an autowrap mode
(DECAWM) sequence to override the switch setting. A soft terminal
reset (DECSTR) or a reset to initial state (RIS) sequence resets the
printer to the state selected by the switch setting. Chapter 5
describes the DECAWM, DECSTR, and RIS sequences.

SP2-4 Function
On Autowrap (factory setting)
Off No wrap

XON/XOFF or Restraint Protocol (SP2-5)
This switch selects XON/XOFF or restraint protocol for data
transmission.

SP2-5 Function Description
On Restraint Para. 2.5.4
Off XON/XOFF (factory setting) Para. 2.5.2

Restraint Polarity (SP2-6)
This switch selects the polarity of the restraint signal when you
use restraint protocol (SP2-5) for data transmission.

SP2-6 Function
On Inverted
Off Normal (factory setting)
