7. Status & Operating Modes
The DPP-250 uses LEDs to indicate various conditions of operation. This
may be charging, active or online, battery low conditions. The following
explains these conditions and LED indication.
LED Function
1. It lights in green – the printer power is on.
2. It lights in red – end of the paper or paper out. After the loading a new paper roll,
LED turns green.
3. It flashes green/red – the printer thermal head is overheating. The printer stops
printing. When the printer head temperature returns to normal the ERR LED lights
ERR
BATT
green and the printer continues to print.
4. It flashes green – low battery.
5. When switching ON the printer, while the LF button is pressed, red and green
lights are rotated after every beep (up to the fifth).
6. While long pressing the ON/OFF button it flashes green/red after a beep. After
releasing the ON/OFF button it lights green.
1. When the adapter is switched ON only one of the BATT LED diodes is lighting
green, depending on the battery status (from left to right - low battery to fully
charged battery). For details see Section "Charging the Battery".

performing step #2.
Step #2: Press and hold the line feed button (LF). While pressing
the (LF) button, press the (POWER) button momentarily
and release when one of the conditions below:
LF Button Operation Modes
Holding LF button while power on
for ~ 0.5 sec and releasing it
after 1-beep.
Holding LF button while power on
for ~ 2.5 sec and releasing it after
2-beep.
Holding LF button while power on
for ~ 4.5 sec and releasing it after
3-beep.
Holding LF button while power on
for more than 8.5 sec and releasing
it after the 5-beep (long 4-tone)
beep.
Holding ON button while power on
for ~ 4 sec and releasing it after 1-
beep.
Holding ON button while power on
for ~ 6 sec.

10. DIP Switch Settings
The DPP-250 is designed to use different methods of
communications. Care must be taken to ensure that the DIP
Switches are not changed from its default factory configuration unless
required.
10.1 DIP SWITCH SETTINGS:
The printer has two absolutely different operation modes.
They are determined by the state of switch Sw2:
•Continuous Paper mode
•Black Mark mode
These two modes detect paper present conditions differently. The black
mark searching mode is designed for proper alignment of the starting
print position on indexed media with printed information.

11. Pairing Info Details
BAUD RATE: Default is 115200
AUTO OFF TIME: Default is 5 minutes
PRINT DENSITY: Default is 100%
CHARACTER TABLE: Default is WESTERN (1252)
PAIRING INFO: Default is (SAVE=No)
Notes:
When saving pairing information, the printer remembers Bluetooth
information of the last device connected (paired) to the printer.
Saving pairing info prevents the printer from asking for passkey
upon initialization. The process for using this option is described
below. "To speed this programming process, you may bypass the memory
switch settings by indicating "NO" via pressing of the <ON/OFF>
button when the printer prints "CHANGE MEMORY SWITCHES" as
shown on page 17. This will advance you to the next level of
setting where pairing can be found".
1. Following instruction on page-13, change the Pairing Info option to
[Save = Yes].
2. Turn the printer on and pair the printer to your Bluetooth device.
3. The printer will now remember the pairing information and not
prompt user for a passkey on every printer initialization.
Clearing Pairing Info:
1. Following instruction on page-13, change the Pairing Info option to
[Save = No].
2. Turn on the printer and pair the new Bluetooth device to the printer.
3. The printer will prompt user for a passkey on every printer
initialization.

15. Magnetic Card Reader (MS Version only)
The DPP-250 has a built-in magnetic card reader. The card
reader incorporates a (3)-track magnetic read head requiring a
single swipe to read field data from all three tracks.
The reader’s magnetic head faces towards the front of the
printer. When placing the card into the reader, the magnetic strip
must be facing as show in the figure above. Keep the bottom
edge of the card flat on the inner base of the reader to ensure
that the magnetic strip passes over the read head evenly.
When swiping the card through the reader, use an even consistent
motion from start to finish. The speed of swiping can vary
however the speed must be consistent from start to finish of the
swipe in order to accurately read card data.
User Notes:
To use the magnetic card reader feature, special software must be
used to read and process the card information. If you do not have
card reading software, please consult your reseller to find out if this
software is available or contact DATECS for recommendations on
compatible third party software solutions.
16. Smart Card Reader (SC Version only)
The DPP-250 has a built-in smart card reader (optional). The smart
card reader is designed to read information stored embedded on
smart chips and process the information using device side
software.
25
Page 26
1 DATECS DPP-250 User manual
When placing the card into the reader, the smart chip must
be facing to the front of the printer as show in the figure
above. Insert the card in to the reader until the card stops.
User Notes:
To use the smart card reader feature, special software must
be used to read and process the smart chip information. Please
consult your reseller if this software is available or contact DATECS
for recommendations on compatible third party software solutions.
