Instructions for the switches, buttons, and indicator lights of the Rongda RP80 series thermal printer.

1.RP80thermal printerpower switch

The power switch is used to turn the printer on and off. The printer's power switch is located on the left side of the printer. Pressing the "-" button turns the printer on; pressing the "O" button turns the printer off.

Notice:

(1) Turn on the switch only after the power supply is connected.

2. Buttons and indicator lights of the RP80 thermal printer

The buttons and indicator panel are shown in the following figure:

3. Set printer mode

80. The printer is set to default settings at the factory. However, the settings can be changed for specific user needs. Use the DIP switches on the bottom of the printer to adjust the printer settings.

The functions of each DIP switch are set as follows:

4. Thermal printer self-test

The self-test function can check whether the printer is working properly. If it can correctly print the self-test checklist, it means that the printer is working properly except for the connection interface with the host computer. Otherwise, it needs to be repaired.

The self-test will print out the software version number, print density, interface type, and English and some Chinese characters in sequence.

The self-test operation method is as follows: After the printer is connected, press and hold the paper feed button and then turn on the printer power. First, the printer will reset and test. After the reset is completed, release the paper feed button in less than 5 seconds. At this time, the printer will perform a self-test and print out a self-test checklist.

5. Special functions of thermal printers

1) WIFI function (WIFI printer)

WiFi is a technology that allows electronic devices to connect to a wireless local area network (WLAN). Currently, the company's printers use the 2.4 GHz radio frequency band. Connections to a WLAN are usually password protected; however, they can also be open, allowing any device within WLAN range to connect.

Currently, models such as 80WUS and 80WUE support WIFI functionality, while other models do not.

For detailed WIFI setup steps, please refer to the "WIFI Settings" section in the integrated tool's setup manual.

2) Bluetooth function (Bluetooth printer)

Bluetooth is a wireless technology that supports short-range communication (typically within 10 meters) between devices. It enables wireless information exchange between a wide range of devices, including mobile phones, PDAs, wireless headsets, laptops, and related peripherals. The Bluetooth standard is IEEE 802.15, operates in the 2.4 GHz band, and has a bandwidth of 1 Mb/s.

Currently, models such as the 80USEB support Bluetooth functionality, while other models do not.

For detailed steps on setting up the Blue function, please refer to the integration tool setup manual.

3) Paper will soon have exhausted its function

The low-paper-ready function uses an optocoupler sensor to detect the status of the printer's paper tray, which is then displayed by the PAPER light on the printer. Specifically, if the paper roll height in the printer's paper tray is greater than 12 units of the optocoupler height (meaning the paper roll is large), the PAPER light is off. If the paper roll height is less than the optocoupler height, the PAPER light remains on.

4) Sound and light function

The sound and light function means that if the printer has a printing task, and the paper has not been removed after printing, the printer will detect the paper feed by using the paper feed optocoupler, read the corresponding value, and send feedback to the printer. The printer will then control the sound and light indicator lights to remind the user of the printer's current status.

Currently, only printers with sound and light functions can support this feature; other models do not.

This sound and light function does not require manual setup by the user.
