I. Product
Thank you for purchasing our LDT114 series thermal barcode printer. This desktop printer
will provide you with safe, reliable and efficient printing at a reasonable price. By using it,
the volume labels can be printed in a wide range of texts or graphic formats. Meanwhile, its
superior function and easy operation make it your best choice among the thermal barcode
printers.
The LDT114 series printer provides thermal printing. The printing speed is adjustable from
2.0, 3.0, 4.0, 5.0 to 6.0 inches per second. It applies to a variety of printing materials,
including paper rolls, paper slices and fan-fold labels. In addition, the printer has the built-in
1D and 2D barcodes that are commonly used, a TTF font and eight sets of English numeric
fonts in different sizes and supports printing in 4 different directions. And through the zoom
function, the fonts can be enlarged. All these will enable you to improve the label printing
efficiencysignificantly.

IV. LED indicator and button functions
This printer has one button and one indicator that can display three colors. Pressing the button in
conjunction with different colors or collaborating with the power switch will enable the printer to
start multiple functions, such as feeding paper, pausing the printer, calibrating the label sensor,
printing the self-test value, and initializing the printer. Details are described asfollows:

11
4.1 LED indicator
LED indicator color
Description
Blue (fixed)
Power on, printer standby to print.
Blue (blinking)
The printer is downloading data or the printer is paused.
Purple
The printer is formatting the data.
Red (fixed)
Printer is in head opened or cutter errorstatus.
Red (blinking)
Printing error occurs, e.g. out of paper, paper jam, ormemory
error, etc.
4.2 General button functions
1. Paper feeding
When the printer is standby (LED blue fixed), the installed paper will move forward one unit
if feed button is pressed once.
2. Pausing of printing operation
While the printer is printing, Press the feed button will pause the operation. At this point,
the power indicator blinks blue. Press the button again to resume theprinting.
4.3 Boot function
This printer has four boot functions that can be used to set or test the printer'shardware.
Please follow the steps below to start the bootfunction:
1. Turn off the printer.
2. Turn on the printer while holding down the button.
3. Release the button with the light signal indicating the required function, as listed in the table

4.3.1 Gap/black mark sensor detection
This test aims to determine the sensitivity of the label paper sensor after the printer is turned on.
When the user installs a new paper roll of a different specification or initializes the printer and
restores it to the factory default value, the label paper gap sensor needs to be re-measured. The gap
detection or black line mark calibration will be completed with your last set value as the reference
value. The default value of this printer sensor is set to gapcalibration.

12
Please follow the steps below to calibrate the ribbon and gap/black marksensor:
1. Turn off the printer.
2. Turn on the printer while holding down the feedbutton.
3. When the indicator blinks red after the first purple, release the feedbutton.
◼ Indicator color cycle mode:
Purple →Blue →Red (blink 5 times) →Purple (blink 5 times) →Blue (blink 5 times) →Blue (fixed)
Note:
Whether the printer volume label sensor detects the gap or the black mark depends on the GAP or
BLINE command sent to the printer (with your last set value as the reference value, the default
value of the printer sensor is set to gap calibration); for more information on GAP and BLINE
commands, please refer to the TSPL2 programmingmanual.
4.3.2 Gap/black mark sensor detection; printing self-test value and entering the
debugging mode
This test aims to determine the sensitivity of the label paper sensor after the printer is turned on.
When the user installs a new paper roll of a different specification or initializes the printer and
restores it to the factory default value, the label paper gap sensor needs to be re-measured. The
gap detection or black line mark calibration will be completed with your last set value as the
reference value. The default value of this printer sensor is set to gapcalibration.
Please follow the steps below to calibrate the label paper by thesensor:
1．Make sure that the label paper is properly installed
2．Turn off the printer
3．Turn on the printer while holding down the feed button
4．When the indicator blinks purple after the first purple, release the feedbutton
◼ Indicator color cycle mode:
Purple →Blue →Red (blink 5 times) →Purple (blink 5 times) →Blue (blink 5 times) →Blue (fixed)
5．The sensor will calibrate the label paper and the printer will print out the self-test value, and
finally enter the debugging mode and print out the value
6．Turn the machine off and on again to return the printer to the normal printing mode
Note:
Before carrying out the label paper sensor calibration, first confirm the type of label to be detected
with Diagnostic Tool or GAP/BLINE command. For more information on GAP and BLINE
commands, please refer to the TSPL2 programmingmanual.
Self-test
When the sensor calibration is completed, the printer prints out the self-test value. Before
connecting the printer to your computer, you can use self-test to confirm that the printer is
functioning properly. The self-test info can be used to check the printing quality of the print head
and know the internal settings of theprinter.

◼ Debug mode
After the self-test is printed, the printer system enters the debugging mode. In the debugging
mode, all the volume labels will be printed as machine code. The ASCII strings on the left are
the data received by the system. The data on the right are printed from the strings on the left, in
hexadecimal values. This function is provided for users or engineers to debug programs. You
only need to restart the printer to leave the debugging mode and return to the normal printing
mode.

Note:
1. Label paper of 4" wide is required to print all the debugging modedata.
2. Restart the printer to leave the debugging mode and return to the normal printingmode,
or press the FEED button to return to the standby state.
4.3.3 Printer initialization
The printer initialization function is to clear the downloaded files in the memory (DRAM)and
restore the print parameters to the factory defaultsettings.
Please follow the steps below to complete theinitialization:
1. Turn off the power.
2. Hold down the feed button and turn on the power. At this point, the power indicatorcolor
will cycle as follows:
◼ Indicator color cycle mode:
Purple →Blue →Red (blink 5 times) →Purple (blink 5 times) →Blue (blink 5 times) →Blue (fixed)
3. Release the feed button when the power indicator is blinking blue. At this point, the printer
will be reset, and then the power indicator will blink purple once, and finally the power
indicator will be blue in ready state.
After initialization, the printer configuration is restored to its default values asfollows:

4.3.4 Skip the AUTO.BAS program
The TSPL2 command language allows the user to load an auto-execute file (AUTO.BAS) into
the flash memory. When the printer is turned on, it will be automatically executed according to
the file loaded by the user. When you want to skip the AUTO.BAS after power-on, you can use
this boot function to ignore this auto-executefile.
Please follow the steps below to skipAUTO.BAS:
1. Turn off the power.
2. Hold down the feed button and turn on the power. At this point, the power indicator color
will cycle as follows:
◼ Indicator color cycle mode:
Purple →Blue →Red (blink 5 times) →Purple (blink 5 times) →Blue (blink 5 times)→Blue (fixed)
3. Release the FEED button when the indicator is fixedblue.
4. The printer will skip the AUTO.BAS program.

V. Diagnostic Tool
Diagnostic Tool is an easy-to-use window-type utility program that allows you to check the current
status and settings of the printer, download graphic files, programs, font files, etc., and complete
firmware updates according to the actual need. Moreover, it supports creation and download of
dot-matrix fonts, transmission of commands or files and so on. By using it, you can complete the
printer setup, check the printer status and troubleshoot the printer usage problems moreeasily.
5.1 Enable the Diagnostic Tool program
1. Move the mouse cursor to the Diagnostic Tool and double click the
left mouse button.
