RONGTA RP411 4 Inch Desktop Label Barcode Printer Instructions

RONGTA RP411 4 Inch Desktop Label Barcode Printer

**Bluetooth pairing and printing (only valid for printers with

Bluetooth)**

The Bluetooth printer needs to be paired with the main device driving the printer before working, and the pairing process is initiated by the main device.
The general pairing method is as follows:

1. Turn on the printer.
2. The main device searches for external Bluetooth device.
3. If there are multiple external Bluetooth device, select the printer corresponding to BOA address (see self-test page for details).
4. Enter the initial password “0000” or “1234”.
5. Complete the pairing.

Please refer to the Bluetooth function description of the main device for the specific pairing method.When pairing, the label printer with Bluetooth interface must be on.
Note: During pairing, please do not turn on multiple printers at the same time, otherwise you may not be able to judge which printer was successfully paired.

After successful pairing, other host computers can still be paired with the printer, and each printer can be paired with up to 8 host computers. If more upper computers are paired with printers, the host computer paired with the printer at the earliest will be automatically removed from the pairing list by the printer. At this time, if this host computer needs to drive the printer for printing, it needs to be paired again. (For multi-connected Bluetooth only)

Use Bluetooth interface for printing

(only valid for the printers with Bluetooth)

For host computers with virtual Bluetooth serial ports (such as mobile phones using SMARTPHONE, POCKET PC, PALM, notebook computer, etc.), after successful pairing, printing data can be sent to the printer via the virtual Bluetooth serial port for printing. If the host computer does not have a virtual Bluetooth serial port, when you want to drive the printer for printing, please consult the supplier of the host computer.

Printer Test

Print self-test page
When the printer is initially installed or there are any problems with the printer, you can run self-test program to confirm the following status: firmware version, printer parameter setting status, print quality, and related setting information of external devices, etc. After confirming that there is no problem with the printer after the self-test, please check other devices or software. This function runs independently of other devices or software.
The self-test method is as follows:

1. Confirm that the printer is connected to power supply and the paper roll is loaded correctly.
2. Confirm that the printer is turned off and the top cover is closed in place.
3. Press and hold the FEED button, then press the POWER button to turn on the printer; release the button after the printer is turned on.

Print with the Window driver

1. To install Windows driver, please refer to “Driver Installation Instruction”.
2. Set the “port” of the Windows driver as the appropriate interface to use. Print the test page with the “Print test page” function of Windows driver.

Label learning

Note: In the following cases, the user can perform label positioning learning so that the printer can better position the label:

• Install and use the printer for the first time.
• First use of printer after sensor cleaning.
• Reuse the printer after it is not used for a long time.
• Replace with a new type of paper roll.
• The printer cannot recognize the mark effectively during printing.

When the printer is ready, press and hold the FEED button for 3s until the standby status indicator flashes twice, release the button, and the printer will start learning and feed paper. If the printer learns under continuous paper mode, the learning is invalid. Users can also complete the learning through the printer tool software (refer to “Instruction for Printer Setting Tool”).

Note: After learning, you can re-open the top cover and place the blank label paper just fed during learning back for printing to avoid paper waste.

USB Interface

The printer’s USB interface socket is standard USB type-B
