6.3 Special Functions of Printer

6.4.1 WIFI function (alternative)

WiFi is a technology that allows electronic devices to connect to a WLAN. Currently, the company’s printers use 2.4G RF frequency band. There is a password for protection for the connection to WLAN; However, it can also be public, thus allowing any device within WLAN range to be connected.
For specific WIFI setting steps, please refer to the “WIFI” setting in the integrated tool setting manual.

6.4.2 Bluetooth function (alternative)

Bluetooth is a radio technology that supports short-distance communication of equipment (generally within 1 Om). It can conduct wireless information exchange among many devices including mobile phones, PDA, wireless headphones, notebook computers, related peripherals, etc. The Bluetooth standard is IEEE802.15, which works in the 2.4GHz band, and the bandwidth is 1 MB/s.

Bluetooth pairing and printing (only valid for printers with Bluetooth)
The RP335 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 MAC 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 RP335 thermal receipt 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.

XII. Troubleshooting

When the printer fails, it can be handled according to the method in this section. If the problem cannot be solved, please contact the distributor or manufacturer.

12.1 The indicator on the control panel is not on

Check whether the power cord is properly plugged into the printer, power adapter, and power outlet or not. Check if the printer’s power switch is on.

12.2 The indicator is normal, while the printer does not work

Run the self-test to check whether the printer can work properly. If you cannot perform self-test, please contact your distributor or the technical service personnel.

If the self-test can be performed normally, check the following:

  1. Check the interfaces at both ends of the connection line between the printer and the computer. At the same time, confirm whether the connection meets the specifications of printer and computer.
  2. The data transfer settings between the printer and the computer may be different. You can use self-test to print out the printer’s interface settings.
    If the printer cannot print, please contact your distributor or the technical service personnel.

XIII. Driver Installation

There are two ways to drive the thermal receipt printer, one is to install the driver directly under XP,Win7,Win8,Win10, Linux, MacOS, the other is to use the port for direct driving.

13.1 Installation for Windows

Add the printer to Windows and assign the driver files in the driver disk to Windows. You can start printing only by calling the print command in the program. In this way, the printer driver of Windows actually converts characters into graphic dot matrix for printing.

13.2 The Port direct drive

In this way, there is no need to use a driver, only the characters need to be directly output to the port, and the built-in and cartridge font inside the printer is used to realize the conversion and printing of the characters. Using the port direct drive way, the printing mode is also changed from page printing mode to line printing mode, making printing control more convenient. If the port direct drive mode is used, the instruction set needs shall be used to control the printing of the printer, and the ESC/POS command set has been integrated inside the thermal receipt printer.
