The Window Size setting specifies the maximum number of infrared frames
the printer can receive before it must send an acknowledgment to the host
computer. If Auto is selected, the printer automatically sets the window
size during power-on reset to maximize link performance.

The Transmit Delay setting defines the amount of time the printer must
wait before transmitting meaningful infrared data to the host computer and
the amount of time the printer requests the host computer to wait before it
transmits meaningful infrared data. The Auto setting is recommended.

The maximum baud rate possible for both the printer and the infrared
adapter is automatically set during power-on. However, if your printer is
situated in a bright or highly reflective environment, you may experience
intermittent communication problems. If you do, select a lower baud rate
for the infrared connection.
Note: Only displayed when Infrared Port is not set to Disabled.

Some printer models allow installation of multiple interface cards;
however, the printer does not allow the activation of more than one
LocalTalk port. This setting lets you select which port is active or lets you
specify that no port is active by selectingDisabled.
The LocalTalk Port menu items are displayed according to the way you
installed your options. For example, if cards are installed into connectors 1
and 3, onlyDisabled,LTa l k O p t i o n 1,andLTa l k O p t i o n 3are displayed.
PCL SmartSwitch Off

SettingPCL SmartSwitch Onlets the printer examine the data on the
parallel interface connection and select PCL emulation if the data indicates
that is the printer language.
If bothPCL SmartSwitchandPS SmartSwitchare setOff,theprinter
uses the language specified in the Printer Language menu as the default. If
only one SmartSwitch setting is setOff, the printer uses the language that
has its SmartSwitch setting setOnas the default.

SettingPS SmartSwitch Onlets the printer examine the data on the
specified network interface connection and select PostScript Level 2
emulation if the data indicates that is the printer language.
If bothPCL SmartSwitchandPS SmartSwitchare setOff,theprinter
uses the language specified in the Printer Language menu as the default. If
only one SmartSwitch setting is setOff, the printer uses the language that

NPA Mode Off
Auto*
NPA is a mode of bidirectional communication that follows theNetwork
Printing Alliance Protocol, A Printer/Host Control Specification Developed by the
NPA. This mode requires the printer to perform special processing of the
data. The NPA Mode menu item under LOCALTALK MENU only applies
to the specified network interface connection.
IfNPA Modeis setOff, the printer does not perform any NPA processing. If
NPA Modeis set toAuto, the printer examines the data to determine the
format and then processes it in either format.
Changing the NPA Mode setting automatically resets the printer.
LocalTalk Buffer Disabled
Auto*
6K to maximum size allowed
Your printer has a variable buffer size that can be changed from the
operator panel. You can configure the size of the input port buffers to meet
your system needs. The maximum size available for modification depends
on the amount of memory in your printer, the size of the other link buffers,
and if theResource Savesetting isOnorOff. To maximize the range for
the LocalTalk Buffer size, you can disable or reduce the size of the parallel,
serial, network, Fax, and Infrared buffers. The Auto setting indicates the
printer selects the buffer size based on the total memory available.
Changing the LocalTalk Buffer setting automatically resets the printer.
Job Buffering Off*
On
TheJob Bufferingmenu item does not display if the formatted hard disk
is defective, is Read/Write or Write protected, or if the Job Buffer Size is set
to Disabled.61 Defective Diskdisplays during printer power on. See61
Defective Diskon page 189 for more information. Also, see Job Buffer Size
on page 93.
Job buffering lets you delay processing of a print job. The job is temporarily
stored on an optional hard disk before being printed. This usually frees the
host computer during the actual printing of a print job.
IfJob Bufferingis setOn, print jobs are buffered to the hard disk. IfJob
Bufferingis setOff,theprintjobsarenotbuffered.
Changing the Job Buffering setting automatically resets the printer.

Use this setting to specify the maximum number of NPA hosts which may
register for NPA printer alerts. When the number of hosts registered for
NPA alerts exceeds the quantity specified by NPA Hosts, any additional
hosts attempting to register for alerts are ignored. Changing the NPA Hosts
setting automatically resets the printer.
LocalTalk Name Lexmark (Printer Name)
This setting represents the printer model name.
LocalTalk Addr (LocalTalk Node Number)
The LocalTalk Address is actually the LocalTalk Node number assigned to
the printer. It is determined between the network and the printer, so it
cannot be modified through the printer operator panel.
LocalTalk Zone (Zone name provided by LocalTalk network)
This setting determines the LocalTalk Zone. This setting cannot be modified

Even Theportexpectstoreceivedataframeswithanevennumberof
logical 1’s per byte. The port transmits XOFF and XON with
even parity. If the port detects a parity error, the port sends an
inverted question mark to the printer instead of the character
sent by the host system.
Odd The port expects to receive data frames with an odd number of
logical 1’s per byte. The printer transmits XOFF and XON with
odd parity. If the printer detects a parity error, the port sends
X5F to the printer instead of the character sent by the host
system.
None The port expects no parity bit when it receives data. The port
transmits XON and XOFF without parity bits.
Ignore The port expects a parity bit when the port receives a data frame.
The port ignores the parity bit. The port uses even parity when it
transmits XON and XOFF.
Refer to parity in theTechnical Referencefor more information.

Print Materials
The print quality and feeding reliability you get with the printer
and options can vary with the type and size of print material you
use. Guidelines are provided in this chapter for each type of print
material.
Always print samples on the print material you are considering
before buying large quantities.
The table on page 125 lists the types of print material you can use
with your printer. It indicates which paper sources can handle
each type of print material.
