Batch: The specified number of labels is continuously issued in a batch.
Cut: The specified number of labels is issued while being cut at the specified cut interval.
Cut issue will be ignored if the cut issue is specified while the printer is in the peel-off
mode.
Peel-off: Next label will not be printed until the current label is removed from the strip shaft.
However, when the application is programmed so that the applicator of a labeler ignores
the peel-off sensor, subsequent labels are printed regardless of whether the current label
is removed or not.

2.19 RIBBON SAVING FUNCTION
When the ribbon saving function is enabled, the print head is raised when non-print area is detected
during printing. While the print head is raised, only the media is fed, causing ribbon loss to be
reduced. RIBBON save, Head up related parameter are included in system menu. However, this
function will not be supported by LE840/LE850. Therefore these parameter setting will be ignored and
no effect.
2.20 AUTO CALIBRATION
When the auto calibration function is enabled, the printer performs an auto calibration at a power on
time and the open/close of the print head. During the auto calibration, the threshold value, gap length,
label pitch, effective print length and whether the ribbon is used or not are automatically detected. The
printer performs subsequent printing based on the detected settings.
2.21 MANUAL HOME POSITION DETECTION
When the manual home position detection function is enabled, the printer feeds media to the print
start position after a power on, a batch reset (cause by Z0 command or W@ command), depression of
the FEED key which follows the closing of the print head block.

(13) Transmission Control: XON/XOFF (DC1/DC3) Protocol
READY/BUSY (DTR) Protocol
XON/XOFF (DC1/DC3) Protocol + READY/BUSY (DTR) Protocol
READY/BUSY (RTS) Protocol
XON/XOFF (DC1/DC3) Protocol
● When initialized after the power is turned on, this printer becomes ready to receive data
and sends an XON code (11H). (Transmission or non-transmission of the XON code is
selectable by means of the parameter setting.)
● The printer sends an XOFF code (13H) when the free space in the receive buffer become
10 Kbytes or less.
● The printer sends an XON code (11H) when the free space in the receive buffer become
512 Kbytes or more.
● When there are no free space in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
XOFF code, the host computer must stop transmission before the printer receive buffer
becomes full.)
● The printer sends an XOFF code (13H) when the power is off. (Transmission or nontransmission of the XOFF code is selectable by means of the parameter setting.)
● The DTR signal is always “High” (READY).
● The RTS signal is always “High”.
READY/BUSY (DTR) Protocol
● When initialized after the power is turned on, this printer becomes ready to receive data
and turns the DTR signal to “High” level (READY).
● The printer turns the DTR signal to “Low” level (BUSY) when the free space in the receive
buffer become 10 Kbytes or less.
● The printer turns the DTR signal to “High” level (READY) when the free space in the
receive buffer become 512 Kbytes or more.
● When there are no free space in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
BUSY signal, the host computer must stop transmission before the printer receive buffer
becomes full.)
● The RTS signal is always “High”.

XON/XOFF (DC1/DC3) Protocol + READY/BUSY (DTR) Protocol
● When initialized after the power is turned on, this printer becomes ready to receive data
and turns the DTR signal to “High” level (READY). The printer also sends an XON code
(11H).
● When the free space in the receive buffer become 10 Kbytes or less, the printer turns the
DTR signal to “Low” level (BUSY) and sends an XOFF code (13H).
● When the free space in the receive buffer become 512 Kbytes or more, the printer turns
the DTR signal to “High” level (READY) and sends an XON code (11H).
● When there are no free space in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
XOFF code or BUSY signal, the host computer must stop transmission before the printer
receive buffer becomes full.)
● The printer sends an XOFF code (13H) when the power is off.
● The RTS signal is always “High”.
READY/BUSY (RTS) Protocol
● When initialized after the power is turned on, this printer turns the RTS signal to “High”
(READY).
● The printer turns the RTS signal to “Low” (BUSY) when the free space in the receive buffer
become 10 Kbytes or less.
● The printer turns the RTS signal to “High” (READY) when the free space in the receive
buffer become 512 Kbytes or more.
● When there are no free space in the receive buffer, the printer discards data received
exceeding the receive buffer capacity, without storing it in the buffer. (After detecting the
BUSY signal, the host computer must stop transmission before the printer receive buffer
becomes full.)
● The DTR signal is always “High” (READY).
● The DSR signal from the host shall be always “High”.
* When the flow control is performed with a Windows PC, “READY/BUSY (RTS) protocol” shall
be selected, and “Hardware” shall be selected for the flow control in the Windows
communication port setting.
NOTE: For “READY/BUSY (DTR) protocol”, data shall be sent after 200 ms from when the
DTR signal is turned to “High” (READY). For “READY/BUSY (RTS) protocol”, data
shall be sent after 200 ms from when the RTS signal is turned to “High” (READY).

(10) Input/Output Signals :
Compatibility mode
Data 1 to 8 (Printer ← Host)
● Input data signals for the 1st to 8th bits.
● Logic 1 is “High” level.
● Min. data pulse width of 2.5 µsec.
nStrobe (Printer ← Host)
● Synchronizing signal for reading the above data.
● Normally at “High” level. The data is read at the rise of the Low level pulse.
● Minimum data pulse width of 0.5 µsec.
Busy (Printer → Host)
● This signal indicates that the printer is in a Busy state.
● When initialized after the power is turned on, the printer becomes ready to receive data
and turns the signal to “Low” level.
● The signal turns to “High” level (in a Busy state) when data is set from the host (at the fall
of the nStrobe signal).
● The signal turns to “Low” level when the printer reads the data.
● When the free space in the receive buffer become 512 bytes or less, the printer keeps the
signal at “High” level (in a Busy state) for 10 seconds when data is set from the host, to
extend the data read interval.
● When there are no free space in the receive buffer, the printer stops reading data. Then,
it keeps the signal at “High” level (in a Busy state) until there are free space in the receive
buffer when data is set from the host.
● The signal is kept at “High” level (in a Busy state) until the current state (one of the
following states) is reset.
• PAUSE state caused by the [PAUSE] key
• Paper end state
• Ribbon end state
• Head open state
• Printer error state
• Initialization in progress upon receipt of the nInit signal
nAck (Printer → Host)
● This signal indicates that the printer has read the data set by the host and is ready to
receive the next data.
● The signal is normally at “High”. It is at “Low” for about 5 µsec. after the fall of the BUSY
signal. The host should usually set data after the ACK signal is turned from “Low” to
“High”.
● If the nAck signal is ignored and the next data is set while the nAck signal is Low, the
“LOW” level continues about further 5 µsec at the fall of the BUSY signal. However, the
data can be received properly.
3-12
nInit (Printer ← Host)
● Reset request signal from the host.
● Normally at “High” level. A low on this input causes the printer to be initialized in the
same manner as when the power is turned on.
* When “Reset process when the nInit signal is ON” is set to “OFF” in the parameter setting
in the system mode, the printer is not initialized even if it receives a low signal.
● When the nInit signal is input during printing, the printer completes printing one tag/label
which is being printed, cancels the next processing, then is initialized in the same manner
as when the power is turned on.
* When “Reset process when the nInit signal is ON” is set to “OFF” in the parameter setting
in the system mode, the next process proceeds without being canceled.
● Minimum pulse width of 0.5 µsec.
Select (Printer → Host)
● This is an output signal which indicates whether the printer is in Pause state or placed
online. The printer can receive data while placed online.
● The signal is at “Low” level while the printer is in a Pause state.
● The signal is kept at “Low” level (in a Pause state) until the current state (one of the
following states) is reset.
• Pause state caused by the [PAUSE] key
• Paper end state
• Ribbon end state
• Head open state
• Printer error state
• Initialization in progress upon power on or receipt of the nInit signal
nFault (Printer → Host)
● Output signal indicating that the printer is in a Fault state.
● At “Low” level while the printer is in a Fault state.
● The signal is kept at “Low” level (in a Fault state) until the current state (one of the
following states) is reset.
• Pause state caused by the [PAUSE] key
• Paper end state
• Ribbon end state
• Head open state
• Printer error state
• Initialization in progress upon power on or receipt of the nInit signal
PError (Printer → Host)
● Output signal indicating a label end or ribbon end state.
● At “High” level when the printer is in a label end or ribbon end state.
● Turns to “Low” level when the label end or ribbon end state is reset.
+5 V
● This is not a signal but a +5 V power supply voltage.
● The maximum current of 500 mA can be taken out.

Nibble mode
PtrClk (Printer → Host)
● Reverse data transfer phase: It is used for evaluating data sent to the host.
● Reverse idle phase: When the printer changes the signal from Low to High, an
interrupt informing the host that the data is available, occurs
PtrBusy (Printer → Host)
● Reverse data transfer phase: Data bit 3 is used for the first transfer. Data bit 7 is used for
the second transfer. Indicates the forward channel is in a
Busy state.
AckDataReq (Printer → Host)
● Reverse data transfer phase: Data bit 2 is used for the first transfer. Data bit 6 is used for
the second transfer.
● Reverse idle phase: This signal is set to high until the data transfer is requested
by the host. Then, the process is performed according to
the nDataAvail signal.
Xflag (Printer → Host)
● Reverse data transfer phase: Data bit 1 is used for the first transfer. Data bit 5 is used for
the second transfer.
HostBusy (Printer ← Host)
● Reverse data transfer phase: It indicates that the host can receive data from the printer by
setting the signal to low. Then, the host sets the signal to
high, and sends the Ack indicating that the nibble data is
received. When the signal is set to low after the reverse
channel data transfer is performed, the interface phase
changes to the idle phase. At that time, there is no
available data on the printer.
● Reverse idle phase: When this signal is set to high according to the low pulse of
the PtrClk signal, the host enters the reverse data transfer
phase again. If this signal is set to high when the
IEEE1284 Active signal is low, the IEEE1284 idle phase
stops, and the interface enters the Compatibility mode.
nDataAvail (Printer → Host)
● Reverse data transfer phase: When the signal is low, it indicates the printer has data to be
sent to the host. And it is used for sending data bits 0 and
4.
● Reverse idle phase: It is used for indicating that the data is available.

Receiving data in the Compatibility mode when the free space in the receive buffer is 512

bytes or less:
● When the free space in the receive buffer becomes 512 bytes or less, the printer stores all
of the already received data in the receive buffer, stays in a Busy state (Busy signal at
“High” level) for 10 seconds to extend the data read interval when data is set from the host,
then reads the data 10 seconds later.
● If the free space becomes 513 bytes or more while waiting for the data read, the printer will
receive the data with the normal data receive timing.
● When there is no free space in the receive buffer, the printer stops reading data. Then, it
stays in a Busy state (Busy signal at “High” level) until a free space is generated in the
receive buffer after data is set from the host.
