Compatible Devices
The DPP-350 (Serial & USB) / DPP-350 (Bluetooth®) portable
ESC/POS thermal printer is designed specifically for use with most
PDA & Smartphone devices.
The DPP-350 can be used in a variety of applications where Printing
/ Card Reading is required.
User Notes:
Compatibility depends on the type of communication method
“Serial / USB / Bluetooth®” your PDA or Smarphone supports and
the availability of DPP-350 driver for your device.
• Determine the method of communications your device supports.
• Next determine if your device is supported by the DPP-350
Drivers & SDKs.

Power On Self-test
The DPP350’s LF switch/button is used for entering various printer
modes. These modes can be used to assist developers in debugging
problems related to programming and communication. The
following explain how to access the various operating modes.
Step #1: Make sure the printer is OFF (On-line LED is OFF) before
performing step #2.
Step #2: Press and hold the line feed button (LF). While pressing
the (LF) button, press the (ON) button momentarily and
release when the Status LED turns green. Release LF
button after the printer Beep once. Shortly after the LF
button is released the printer will print self-test.

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
