6. Functions
6.1. Self test
The DPP-255 has a built-in test pattern that shows the printer’s current configuration as well as the
various resident printer fonts. The self-test can also be used as a troubleshooting tool to determinate
problems or battery level.
Holding FEED button while power on for ~ 0.5 sec (STATUS LED lights)

6.2. Page mode
In page mode the result the result of incoming commands is forwarded to a reserved memory
area (page). The page place and size is defined using commands ESC W. Command GS T selects the
print direction in this page. At the end the collected information is printed using one of the
commands, provided for this. Commands ESC FF and GS FF print only the currently defined page, but
command ESC Z prints the area between the first and last line containing at least one black point.
All commands except GS L and GS W work in page mode. The centering and right alignment
(command ESC a) id working in the currently defined page width.
6.3 Ruled lines
The printer has two line buffers with size the maximum printing width (paper width in standard
mode or the selected page width in page mode). When ruled lines are active, then every horizontal
line of the text line is combined with the selected ruled line buffer. Bit ‘1’ in the ruled line buffer is a
black dot in OR mode and inverts the color of the dot in XOR mode. Two commands allow the ruled
line buffers to be printed without combining with a text line.
When pressing the FEED button, no ruled lines buffer is applied.
All ruled lines commands start with symbol DC3 (ASCII code 13h). Please see command DC2 =, too
6.4. Protocol mode
The purpose of this mode is to give stronger real time access to the printer. All input data are
sent in packets. The printer returns an answer to the packet immediately.

No error signal Is detected
- Standby – It is possible to print and the printer waits for printing data
- Initialization – Initialize printer memories. The printer goes OFFLINE during
initialization. After completing initialization, the printer goes stanby.
- Status of waiting error cancellation – Printer status move to this status when some
error factors like paper end etc. is removed. OFFLINE status and STATUS LED remain its
status. Printer becomes standby when FEED button is pressed.
Status of detecting errors
- Temperature – The print head temperature is increased when heavy-duty printing is
continuous. If the print head temperature exceeds 70 degrees oC, operation of the
print head is automatically stopped to prevent overheating. The printer goes OFFLINE.
- Paper empty – Detect the paper empty through paper end sensor. Paper runs out and
the printer detects paper empty, the status LED turns On and the printer goes OFFLINE
- Paper cover open – When the Paper cover open, the status LED turns ON ant the
printer goes OFFLINE

The DPP-255 printer is equipped with Bluetooth module obtained MFi license which can be
communicated with the device of iOS including iPhone, iPod, and iPad. Besides iOS devices, Android
and PC terminals can be communicated through SPP profile and the printer is widely used for
electronic equipment.
PIN code: 0000
1) If 1Mbites or larger data are sent to the printer during BT communications, the printer buffer becomes over
loaded and it causes the printer not to print properly.
2)It is recommended to change the default PIN code of the printer.
3) In case of interference occurred at the circumstance, turn off the power of interrupted devices ot move the
place where is not influences.
